In recent years, the number of the accidents of the dangerous facility is increasing. One of the reasons of the accidents is the corrosion by aged deterioration. For the oil storage tanks, the initial thickness is important to accurately estimate the metal loss. Since the thickness is usually not measured before using the tanks, the designed thickness is used as an initial thickness. However, the actual initial thickness distribution is unknown because of the allowable error. Therefore, in the present study, the initial thickness distribution of bottom floors is estimated due to the method using the average value and standard deviation of the thickness measurement data of shut down inspection. Furthermore, from the results, the corrosion damage parameter was proposed by using the relationship between the cumulative probability and the depth of corrosion.

Fiber Reinforced Plastics (FRPs) are used as pipe, tank and duct in chemical plant because they have corrosion resistance and strength. However, FRPs might degrade slowly over a few decades. Since FRP and the other organic materials have been used rather recently and there is not so much information of durability compared with metals. Furthermore, applicable non-destructive test (NDT) on FRP is not confirmed yet. Hence, it is important to apply a NDT method on FRP equipment used in chemical plant. In this report, Ultrasonic Test (UT) inspected the degraded FRP tank used in chemical plant and error of UT was evaluated as standard deviation. The results of SEM, EDS and FT-IR indicated that degradation of this tank was categorized as 'surface reaction type'. Moreover, 'Damage Factor' in case of FRP tanks was calculated by reference to API 581 and 'Inspection Effectiveness' of UT was proposed from Risk Based Inspection points of view.

During lifecycle of chemical plants, various changes of raw materials, products, operation and/or process structure are performed during the plant life cycle in order to cope with the economic environment. However, it may lead to a leak, a fire, an explosion accident if the operating conditions after the change do not satisfy the mechanical integrity of the plant, and the management of change becomes indispensable. The changemanagement is classified into tow; management of changes and process hazard analysis (PHA), and many incidents are taking place for insufficiency of PHA. In this study, applying HAZOP record for PHA in change management is proposed. The HAZOP record protocol is defined, and, the performance of PHA is demonstrated.

High explosives are useful material to generate great amount of energy in short time. Since controlling their releasing energy is hard, the use of explosives is limited to specific fields and industries. The reduction of the explosive powder mass used at a time makes the handling safe, and use of explosives in a continuous producing process leads the new utility of the explosion. Based on this concept, we enclosed small mass explosives with a polyethylene sheet and initiate them by using metallic foil explosion. In present study, we use comparatively small power-supply unit(200uF,450V) with an improved foil explosion system. Finally we observed much better results of the initiation of PETN explosives.

The purpose of risk assessment (RA) is the determination of quantitative or qualitative value of risk related to a concrete situation and a recognized hazard. The results of them are used for preventing occupational and process accidents. For the workplace in the chemical process industries (petroleum refinery, petroleum chemical, chemical, etc.), we summaries three types of RA methods (chemical RA, plant facility RA, work safety and health RA) which contributes to prevention of occupational and process accident, and the targets and purposes of each RA method which is implemented at each stage of plant lifecycle engineering. To perform RA and consideration and implementation of risk control adequately and to share the process safety information can make it possible to prevent the occupational and process accident from occurring and mitigate the damage.

Risk management system for supporting process safety management through a plant-lifecycle is developed by use case driven development. The use cases are directly derived from the business process model and associated with primary actors with consideration of the corresponding role of plant-lifecycle engineering and process safety management activities. Functional requirements for the support system are defined in accordance with the use case analysis and implemented to the existing engineering support tools. The implemented functions are strictly combined with user requirements, because they are derived from to-be use cases based on a reference business process model.

For a chemical plant, changes caused by load fluctuation, transition of product markets, revamping of the plant's facilities, et al. are inevitable. Uncontrolled changes caused many accidents or disasters. Thus, management of change (MOC) has been a very important issue in process safety management. In this paper, it is considered that the MOC is divided to two parts: one is an individual change management and the other is a management of them. An individual change management is an instance of engineering over the plant lifecycle (Plant-LCE). A business flow of MOC is expected to be based on a business process model (BPM) of Plant-LCE. An overview for the BPM of Plant-LCE has been proposed. Using an individual change management example, this paper demonstrates that a business flow of the MOC can be described in the overview of the BPM of Plant-LCE. According to the results, importance of sharing information among design, operation and maintenance activities and requirement of supporting system for MOC and Plant-LCE were indicated.

To improve the performance of Automatic Collision Avoidance Systems, it is essential to consider the vehicle dynamics when the vehicle with the system urgently avoids an obstacle in downhill. In this paper, we confirm the performance of Automatic Collision Avoidance System on the decline road by computer simulation. In case of the steep downgrade or quick steering wheel speed, it is shown that the vehicle motion is not straight after end of automatic steering input. Finally the cause of such vehicle motion can be considered by yaw-rate time series data.

This paper analyzes the driver's collision avoidance behavior in an emergency. Experiments, in which participants drove a test vehicle at around 40km/h and a dummy vehicle suddenly appeared from the side, were conducted on a proving ground. Two out of 56 participants could not respond to the emergency situation, that is, they did not apply the brakes. The driver behaviors were analyzed, for example, it was revealed that average brake response time was 0.45 seconds and average deceleration after braking was 7.0 m/s^2.

When a vehicle is equipped with two or more driving support functions as compared with a single driving support function, the driver has need to understand the contents of each driving support function. If the driver does not understand each function enough, the drivers' operation for risk avoidance may be delayed. In this study, each alarm sound was designed in consideration of drivers' mental model related to the collision to the preceding car or lane deviation. The drivers' operation was evaluated through the Monte Carlo simulation which was based on results in a driving simulator. As a result, two different kinds of driving support alarm systems showed that the drivers' risk-avoidance behavior to avoid collision or lane deviation was not worsen when two alarm functions were mounted, compared with the situation when the single alarm function was mounted.

In this research, we focused on the saliency map that predicts the visual attention based on analyzing the image of driver view, and we apply the saliency map as an index of the risk level of traffic environment. We proposed an evaluation method of intersection visibility using Saliency map, and investigated correlation between driver's timing of discovering intersection and visibility of intersection. From the experiment result, we confirmed that the coefficient of correlation is 0.88, thus strong correlation between them was confirmed. In addition, we proposed an alarm system according to the intersection visibility and evaluated the validity of the alarm system in a driving simulator experiment. From the experiment result, we clarified that brake start timing was delayed and sudden braking was often occurred at the low visibility intersection. Furthermore, we confirmed the effect of alarm system that induced a driver to discover the presence of the stop sign and operated the braking safely.

A procedure is established to digitize a three dimensional structure within a carbon foam using a commercially available X-ray Computed Tomography (CT). The digitized model will be used to evaluate radiative transport coefficients such as absorption and scattering coefficients of the carbon foam. The obtained radiative transport coefficients will be used to calculate radiative transfer in the porous material, which is believed to strongly affect a thermal protective performance of an atmospheric entry vehicle. For the first step to achieve the objectives of the present study, X-ray images are obtained by using a micro-focus X-ray CT system(Shimadzu, SMX-100CT), and the validity of the 3-dimensional digitized model so obtained is discussed. In the present study, whether a representative elementary volume (REV) is taken or not within the digitized model is examined. It should be noted that the REV represents a minimum size of the digitized model within which a macroscopic nature of a material such as porosity can be replicated. The results show that even though a carbon-based material is known to be difficult to model a three-dimensional sturucture by using a X-ray CT due to its low absorptivity against X-ray beams, we can successfully reproduce the macroscopic porosity value of about 90% by using a digitized model larger than REV.

When we produce a thermal protection system (TPS) for the space vehicle entering a planet, the arc-heated wind tunnel is used widely. The arc-heated flow is very complicated. In addition, we assume the on-board measurement of spectroscopy to understand the flow properties of very strong shock-heated gas. Present work show a method of head-on measurement of spectroscopy used optical fiber in high-enthalpy gas. At first, the head-on measurement of spectroscopy and side-on measurement were compared. At argon flow, the electronic excited temperature has 500 K difference between these two methods. At the nitrogen flow, in the case of the head-on, it could see only the spectrum from nitrogen atom. The light weight ablator (like PICA) materials was used as TPS. The head-on measurement could operate over the 10 seconds for light weight ablator. In addition, the time resolved measurement of spectroscopy caught the change of the property of spectrum.

The reentering capsule with super-orbital velocity in manned space flight missions such as return from the lunar orbit, or from asteroids requires lifting entry in order to restrict deceleration and heat transfer rate within a given range. At the first entry, appropriate control of the L/D, namely bank-angle, based on the states of the vehicle, is crucial not only for the landing point guidance but also for the flight environment relaxation. In the process of research activities on the synthetic analysis of the skip entry of the lifting-flight capsule with super-orbital velocity, the present paper analysis introduces the state-estimation by extended Kalman filtering (EKF) method with noise superimposed on the true value. Especially the effect of the attitude motion during the bank-control on the control errors is quantitatively estimated. The state estimation of the reentry flight has been presented thorough experiment/flight data and numerical simulations.

Japan Aerospace Exploration Agency has a plan to develop the HTV-R which is an extended version of the HTV. The HTY-R will be a spacecraft for developing a re-entry capsule similar to the Apollo spacecraft. The recovery on the sea surface is the promising methods to develop a Japanese capsule, therefore the shock mitigation at splashdown is one of the key technologies. In the present study, preliminary splashdown tests using a 6.8 percent scale model of the re-entry capsule were performed in the required three kinds of splashdown velocities and four kinds of initial attitude angles of the model. A measuring system of acceleration was constructed, which recorded time histories of acceleration and sent the data to PC wirelessly and measured its splashdown behaviors using five accelerometers. Experimental data obtained from five accelerometers are evaluated based on water impact theory that is considered from virtual mass and conservation of momentum. It was made clear that the maximum acceleration at splashdown was obviously mitigated in the case of initial attitude angle 30 degree compared to other initial attitude angles.

A prototype of an embedded optical sensor mainly made of a quartz fiber and a Si photodiode is developed to measure recession behavior of an ablative heatshield material. In order to test the operational principle of the developed sensor, a composite test specimen is prepared: a spread carbon fiber sheet is put onto a graphite tube. The spread carbon fiber sheet is ablated by irradiating the frontal surface of the sheet by using a CO_2 laser, and the radiation emanated from the back surface of the heated sheet is detected by using the fabricated optical sensor embedded into the graphite tube. The irradiated surface is recorded by using a video camera. In the present study, the ablative characteristics of the spread carbon fiber sheet are interpreted by comparing the recorded images with the temporal variation of the sensor output voltage. The results implies that the developed sensor works in principle: the sensor can successfully detect the rapid increase of the temperature of the sheet, and the mass loss behavior of the ablated spread carbon fiber sheet.

The utilization of the micro/nano satellites with 50kg or less weight has been rapidly growing and lots of micro satellites are going to be launched within several years. The micro/nano satellite has been expected to realize the various space missions with low cost and short development period. For example, large apparatus antenna with sufficient shape accuracy is required for future earth observation mission. Other than these requirements, the micro/nano satellites generally have deployable solar array panels to provide sufficient electric power. Thus low-cost deployable panel structure is getting important for micro/nano satellites. The key technology to reduce the production cost of the deployable panel structure is the simple and reliable deployment device, for example the hinge with sufficient deployment torque, the joint or latch mechanism with appropriate accuracy of relative position and angle, the hold release mechanism with enough holding force. Based on the above, we are advanced the development of the hinge with latch mechanism and the hold release mechanism as a simple and low-cost panel deployment device. In this paper, we will report on the status of development of the hold release mechanism and the hinge with latch mechanism which is the deployment mechanism of panel structure for micro/nano satellite.

Recently, deployable membrane structure has been applied to deorbit mechanism for small satellite. One way to deploy membrane structure is to use convex tapes as extension booms. This membrane deployment mechanism is simple and lightweight. Convex tapes winding around a spool store strain energy. Putting some guide rails around the spool, the convex tapes unwind from the spool and extend straight along the guide rails like extension booms. We will make two kind of guide rails and perform deployment test. In this report, we will show deployment dynamics of convex tapes, and show result of two kind of examination.

A guide for the thermal design of micro and nano satellites is proposed in order to complete the thermal design of micro and nano satellites for about 1 year. Two concepts of thermal design are considered to keep the temperature change of components within the design temperature range of components. One concept is to decrease the temperature change using the whole heat storage of the micro and nano satellite. The other is to decrease the temperature change of the inner structure where the components with the narrow design temperature range are mounted. The temperature of micro and nano satellites designed in the former concept is calculated using one-nodal analysis method. The temperature of micro and nano satellites designed in the latter concept is calculated using twonodal analysis method. The combinations of optical properties on structures and components to keep the temperature within the design temperature range of components are clarified using one- or two-nodal analysis. Then, the multinodal analyses are carried out to be designed in detail based on the optical properties clarified from the one-nodal analysis and two-nodal analysis. This guide of thermal design is applied to Hodoyoshi-1 satellite. Hodoyoshi-1 satellite is the micro satellite that is about 50 cm in width, 50 cm in depth, 50 cm in height, is about 50 kg in mass, has two inner plates, has solar cells on the body, flies on the sun-synchronous orbit of the 500 km of altitude and is pointing to the Earth. The thermal design of Hodoyoshi-1 satellite has been completed for about ten months. The validity of this procedure is confirmed and the problems of this procedure are clarified.

Fukuoka Institute of Technology (FIT) launched a satellite (FITSAT-1) whose object is to study and test optical signal transmission using LEDs between FITSAT-1 and ground station. It is extremely hard to track our satellite, because speed of satellite is fast comparing to the normal planet and the sight angle of observation must be small in order to decrease the stray light from the sky. Therefore, we have developed the system to search and track this satellite precisely. This system is divided into two parts, namely searching and tracking. The searching part is based on scanning of observation direction using a fast galvano scanning mirror. The tracking part is based on the feedback control by image processing and stepping motors. This system is automatically controlled by Lab VIEW program.

Recent years, there are problems of design of Electricity Power Subsystem (EPS) in university satellites. For example, it becomes impossible to operate satellites because battery charging or power supplying is stopped. Therefore, it is necessary to consider power balance, charge control, sizing of solar cells, inhibit function, and others, and evaluate the system from environmental test such as thermostatic bath, vacuum, vibration, shock and so on of the EPS for the satellite beforehand. In this research, for the purpose of sharing knowledge of development of satellite, we show the case and improvement measures of EPS of 10cm class satellite SEEDS and 20cm class satellite SPROUT from the point of view of operation and development. In SEEDS from the point of view of operation, it was confirmed that battery voltage is high level voltage attributing to a causes of battery protection circuit. In SPROUT from the point of view of development, it was confirmed that EPS didn't operate normally because of voltage drop and was renovated by optimization of component placement and extending circuit pattern and harness and confirmed the operation of EPS by environmental test such as vacuum, thermostatic bath, vibration and others.

We have developed a computer assisted instruction system that generates the 3-dimentional (3-D) model from the projection views of the object in order to enable students to learn machine drawing without the help of teachers. In this study, the function of overlaying the projection views on the 3-D model was proposed for the purpose of assisting to understand the correspondence of the projection views to the 3-D model. Each vertex of the projection views are linked to the 3-D model with dotted lines so that one can verify the validity of existence of the vertexes in the 3-D model and can find the portions and the contents of the errors included in the projection views. The correspondence of the lines between the projection views and the 3-D model can be also found by moving the overlaid projection views along those normal directions. By conducting trial use, it was demonstrated that one can specify errors in projection views by means of the proposed function.

The method to evaluate the effect of regenerator efficiency on an indicated work of low temperature differential Stirling engine is proposed. The method enables to estimate the ensemble averaged temperatures and temperatures at the outlet of the regenerator in both hot side and cold side of displacer chamber. The estimation requires assuming the surface temperatures of both sides heat exchanger, the ratio between the difference between regenerator outlet temperature and heat exchanger temperature and the difference between ensemble averaged temperature and regenerator outlet temperature, and regenerator efficiency. The abovementioned ratio caused by three temperatures can estimate by two-dimensional steady-state CFD, and is about 0.3 in case of conventional low temperature differential Stirling engine. Obtained ensemble averaged temperatures will cause an indicated work by isothermal model calculation, and regenerator efficiency will affect on the calculation result. Although the empirical method to estimate regenerator efficiency has been proposed, much inexpensive method for engineering education or hobby should be proposed as next step.

There are a lot of scientific phenomena and technological matters around us. Teaching materials in the science classes for children carried out last year were discussed in this report. The authors have learned some aspects from the science classes. First of all we should adopt the materials which are familiar to children and are able to attract the concerns of them. Secondly, the experiments should be certainly taken in the programs and for the experiments we should prepare the materials which could be easily available. Special tools should not be considered because children could not use. Expensive materials should not be considered because children could not get. Finally, fundamentals and principles on various scientific phenomena should be easily explained. It was expected that explanations about fundamentals and principles should be done after experiments or making. The results about questionnaires showed the encouraging effects of classes. It seems to be important for us to expand our actions into the community.

The Japanese engineering education is demanded now to possess engineering design education. However, this demand is accompanied with difficulty, because the problem that engineering design wrestles with is not the more or less simplified problems that engineering studies settled. Engineering design is the process of trial and error to break through the real situation including some various, vague, complicated and uncertain problems. Engineering design skill of engineer is ability to achieve this process. The engineering design process will be understood as an iterative process which is performed between two rationality; one rationality is internal-rationality which constitute the solution such as engineering science, and another is external-rationality in the meaning that the solutio Tn acts good for work place such as performance and conditions.
