In 2002 a mother was killed in an accident caused by a tire fallen out of the front left hub of a large trailer truck. Investigation found that the tire fell off because of fatigue failure of the hub. Investigation also found that cracks had been found in many hubs of the same type, but the manufacturer of the truck, Mitsubishi Motor Company, had not taken such steps as recall in order to prevent an accident. Two managers of the manufacturer were indicted for negligently killing a person, and found guilty. We have studied the criminal decisions of the case, which went through the first instance and the appeal, and even to the Supreme Court. Although all the three instances found the defendants guilty, they gave slightly different reasons. Close study of their reasoning has shown that the true cause of the fatigue failure is still unknown, and there is still reasonable doubt that a recall, even properly performed, may not have prevented the accident.

In 2004, Mitsubishi Motors Corporation recalled the D-type hub of a front shaft of a large-sized truck due to fatigue. The managers of the Mitsubishi were indicted for too late execution of the recall without any scientific discussion on the fatigue mechanism. The paper presumes the fatigue mechanism using the similar accident of a hub/wheel in the new transit Yurikamome. The hubs have a vibration due to positive camber angle; the vibration induces a wear between the hub/wheel: the wear makes a deformation of the worn flange part of the hub/wheel; a hub bolt tightly fastens the wheel/hub with slightly titled posture; a small radius corner has an excess tensile stress; the stress makes crack propagation. The failure scenario of the Mitsubishi hub accident should be similar to that of the Yurikamome hub.

In 2002 a mother and a child were injured and killed in an accident caused by a tire fallen out of the front left hub of a large tractor. Usually, in such an accident, engineering accident investigation is conducted thoroughly. However, it seems that this case of the engineering investigation by a specialist is insufficient since correspondence of a maker had too many problems. So, in this paper, I analyzed the accident carefully from a viewpoint of fracture mechanics. As a result, I got reasoning that the margin of safety ratio of the hub of accident vehicles was insufficient. A maker's engineers must also have had the same conclusion in the early stage. Why couldn't the maker recall these tractors independently?

This paper describes a new model for industry-academia collaboration, "Market to Business to Academia" (M2B2A) model, which will enhance academia's role in social innovation much more effectively than the conventional model of "Academia to Business to Market" (A2B2M) model that traditionally seeks collaboration with industry on academia's proprietary technologies. In this new M2B2A model, an academic institution seeks a collaborative research with a business enterprise on a new technology that the market requires the enterprise to develop. This paper will quantitatively discuss performance of the M2B2A model that the University of Tsukuba initiated, and compared it with the A2B2M model. As more and more financial autonomy is required for universities, M2B2A model for industry-academia collaboration will be increasingly important.

Head injuries are the most common cause of road users in real-world accidents. For pedestrian safety, this paper describes the developments of head injury risk curves and development of test tools, i.e., child and adult pedestrian headform impactors, for evaluation of safety performance of vehicle structure. For the development of head injury risk curves, relations between head injury risk and head injury criterion (HIC) are clarified based on accident reconstruction by means of headform impactors. In 2005, Japan introduced the type approval test for pedestrian head protection using the newly developed pedestrian headform impactors. For cyclist safety, this paper shows that wearing a helmet has a great potential in preventing cyclist head injuries based on impact experiments of the adult headform impactor against vehicle A-pillar and road pavement.

Mass production of surface mount devices (SMDs) relies heavily on reflow soldering and has become the cornerstone of today's electronic industry. However, the traditional reflow soldering technique is characterized by high heating temperatures, toxic solder materials and low recycling rate of SMDs. Here, we introduce a new patterned structure of nanowire arrays named a surface fastener through which cold bonding for surface mount technology can be realized. The mechanical bonding enables normal and shear bonding strengths of more than 5 N/cm^2. Simultaneously, the parasitic resistance of a pair of surface fasteners is only approximately 2Ω. The present technique can be performed at room temperature, thereby improving the process compatibility and reliability of SMDs. Surface fasteners based on high melting point metallic nanowires are temperature-resistant for many critical applications. In addition, bonding without solder material is positive for the recycling of rare metals in SMDs.

In development of high strength magnesium alloys with large elongation for medium plate, effect of rolling process and heat treatment of magnesium alloy on mechanical properties of rolled Mg-Al-Mn-Ca (AMX alloy) and Mg-Al-Zn-Ca (AZX alloy) alloys with thickness of 3 mm were investigated used by cast materials. The casting and rolling process and mechanical properties of flame-resistance AMX and AZX alloy were examined. Casting is carried out by the antigravity suction casting process and then subjected to hot rolling. The microstructure and mechanical properties of the cast alloy were dependent on the cooling rate and molten metal temperature. In rolling process, the dendrite structure was also elongated in the rolling direction after total reduction in thickness of 60%. The existence of shear deformation of the microstructure when the total reduction more than 60%, this stage, Al-Ca compounds were beginning to be crushed. As the result, we were able to rolled plate of 3 mm in thickness of this alloy subjected to rolling process showed a high tensile strength and large elongation by dynamic recrystallization and recovery.

Fiber reinforced thermoplastic composites has poorer matrix resin impregnation to fiber reinforcement, because of extreme high viscosity of molten thermoplastics. Intermediate materials using Micro-Braiding technique have been developed to overcome these difficulties. In this study, composite textiles plates were fabricated under various fabrication conditions, and their impregnation were investigated experimentally and predicted by theoretical formulae. As a result, impregnation increased with molding pressure and time, and impregnation of single-ply textiles is improved compared with that of multi-ply textiles because they have more collapsed fiber bundles, hence closer impregnation distance. On another front, the analytical predictions were in disagreement with the experimental results.

Rolling of neutrophils on vessel wall of post-capillary venules is the earliest event of a cascade of a multistep process of extravasation for the host defense. Since this rolling is considered to be a trigger to initiate the subsequent extravasation process, numerous in vitro studies have been performed on their rolling characteristics using parallel flow chambers mainly focusing on contribution of binding of adhesion molecules on neutrophils and endothelial cells to their behavior. In addition to the binding of the molecules, axially aggregated red blood cells in the vessels are thought to help the neutrophils to be marginated to the vessel wall. Though the pressing force applied to the cells on the vessel wall could enhance possibility of the bond formation of the molecules, the parallel flow camber cannot apply such a force to the cells in the experiment. In this paper, a homemade inclined centrifuge microscope system was introduced. Mechanism of the system to apply a pressing force to the cells was briefly explained. Then, some experimental results of rolling characteristics of HL-60 cell line, which is a well-known model cell of neutrophils, on various types of substrate under the pressing forces were shown.

Non-scanning 3D-CT technique using a multi-directional quantitative schlieren system with flash light sources, is proposed. The image set of 20 directional schlieren images of target flames are processed by MLEM CT-algorithm to obtain the 3D reconstruction of instantaneous density distribution. In this investigation, the target high-speed turbulent flame is anchored on the burner of a nozzle exit diameter of 4.2 mm. The average flow velocity of the propane-air mixture of equivalence ratio of 1.1 is set to be 4, 6, 8 and 10 m/s. Results of the 3D-reconstructions indicates that the distributions show the complicated shape of the high speed turbulent flames. Three-dimensional solid models of the 3D data have been also made by 3D-printing for data visualizations.

We had proposed a lifetime-based simultaneous measurement method of temperature and velocity and applied it to several liquid or gaseous flow fields. Temperature sensitive luminescent particles were dispersed into a flow. The luminescent lifetime indicates temperature and the particle displacement shows velocity. This study focused on the uncertainty and applicability of the proposed method. Measurement errors were analyzed by using simulated ideal images. When the displacement was smaller than 8 pixels between images, velocity measurement errors were at the same level as that of traditional PIV method. The errors of temperature (lifetime) calculation became large with the displacement over 8pixels during a decay. Then, we measured temperature and velocity of gaseous flow around a heating cylinder. The experimentally measured results were compared with numerical ones.Key Words : Flow visualization, Temperature, Velocity, Combined measurement, Temperature Sensitive ParticlesWe had proposed a lifetime-based simultaneous measurement method of temperature and velocity and applied it to several liquid or gaseous flow fields.

We proposed spatiotemporal filter velocimetry (SFV) based on a frequency analysis of time-series spatiotemporally-filtered particle images, which conisits of an imaging system using a highspeed camera and a software program for image processing by a computer. Main features of SFV are (1) velocity of a single tracer particle is measurable, so that accuracy, spatial and temporal resolutions can be as high as LDV, (2) simultaneous measurement of two velocity components is possible at arbitrary multiple points in recorded particle images, (3) it is applicable to flows with low concentration of tracer particles, (4) processing conditions such as an interrogation area, a pattern of spatial filter, a shift frequency and a frequency evaluation method can be easily optimized after recording particle images, (5) translational velocity of a pattern such as bubble and wave velocities can be measured and (6) it is applicable to non-rectangular interrogation regions by using coordinate transformation. In this report, we breifly explain the principle of SFV and present several applications of SFV to demonstrate its potential.

Regulations are continuously tightening. LEV III starts in MY 2015 and Tier3 regulation starts in MY2017. Both regulations are nominally a 70-80% tightening of NMOG (non-methane organic gases) and NOx from LEV n or Tier2 levels. These are roughly 40% tighter than Euro 6. More than 75% of emissions in FTP-75 regulatory test are released in the first a few seconds after cold-start. The heat capacity of catalyst the substrate is a factor effecting catalytic light-off. Historically, substrates with thinner walls and lower heat capacity have been developed to improve cold-start performance. A new material and process technology has been developed to achieve faster light-off performance with higher porosity compared to conventional substrates. The new material enables thin walls (2-3mil) in a 55% porosity substrate to reduce heat capacity by 30-38% while maintaining adequate strength. Faster light-off performance using new substrate was demonstrated in laboratory bench and actual vehicle testing.

A Particle Number (PN) limit for Gasoline Direct Injection (GDI) vehicles was introduced in Europe from September 2014 (Euro 6b). In addition, further certification to Real Driving Emissions (RDE) is planned, which requires low and stable emissions in a wide range of engine operation, which must be durable for at least 160,000 km. To achieve such stringent targets, a ceramic wall-flow Gasoline Particulate Filter (GPF) is one potential emission control device. This paper focuses on a catalyzed GPF, combining particle trapping and catalytic conversion into a single device.

Measuring steam quality could help increase the efficiency of industrial heating processes and air-conditioning systems. Furthermore, in various industrial applications, slight changes in steam quality greatly affect the quality of manufactured products. Current available technologies do not allow real-time, non-invasive measurement. Therefore, there is an important need for accurately measuring steam quality. We have developed a steam quality measuring system using the near-infrared region of the electromagnetic spectrum. The technology was tested on a pipe line connected to a boiler. This paper describes the technology and the results of a prototype evaluation.

It is well known that steam wetness sometimes causes measurement errors of steam flow meter. However, it is difficult to clarify a particular error quantitatively in actual plants or factories, and thus far, there has been no established method for estimating the error caused by steam wetness. Morita et al. conducted experiments for flow rate measurement under wet steam flow with 3 types of the steam flow meter; orifice, vortex and ultrasonic flow meter, and proposed correction methods for measurement error. This paper introduces evaluation of flow regime under wet steam flow by visual observation for considering the effect of flow pattern on the measurement error.

Steam flow measurement of a pipe flow such as factories and power stations is one of the significant techniques that enable us to diagnose and control the energy flow. The conventional flowmeter, however, needs the installation of the spool piece that disturbs the stable and continuous operation of the plants. In this study, the clamp-on ultrasound flowmeter has been developed by using focusing sensors. By the numerical simulation, the ultrasound propagation through steam and metal pipe was firstly investigated. The effects of the external damping material, applicable vapor pressure range as well as the appropriate shape of the acoustic lens were analyzed that was followed by the feasibility test of steam measurement system. Pressure and sensor dimension were varied to compare the efficiency of the ultrasound transmission between transducers. The signal processing algorithm was developed in order to discriminate the direct signal through the steam flow from the unwanted circumference noise through the solid stainless pipe. The linear relation between flow rate and ultrasound peak shift was confirmed.

It is necessary to structure a research and treatment system for squarely dealing with an elderly patient's cancer in Japan as a country with arrival of a super aging society. For that reason, it is important for healthcare professionals who provide medical care and rehabilitation to comprehend physical/mental characteristics of elderly patients. Cancer rehabilitation has been implemented so far, but there is still no clear relation between "Cancer" and "Rehabilitation" yet. Firstly, it calls for urgent attention to actually practice a cancer rehabilitation by accurately assessing a cognitive function and physical function of elderly patients. Furthermore, it is preferable that assessment results/issues in clinical practice should be utilized not only for healthcare professionals but also for development of welfare equipments. Even though it might be difficult to be directly connected between patient and engineer, it could make a contribution to a development of Kansei engineering in future through healthcare professionals such as occupational therapist.
