According to the present Building Standards Law, the structure of a restraint device is not defined in detailed standards corresponding to acceleration. Partly because of this, it was found from last fiscal year's research that only a few amusement facility enterprises either accurately know or have interest in acceleration data. In this research, standards on a restraint device will be reviewed by collecting scientific knowledge by means of actual measurement of data, interview to amusement facilities, etc. concerning the structure and combination of restraint devices corresponding to the acceleration and type of amusement facilities. Also, review will be made on conformity ・ response to overseas standards to assess standards, and structure standards specifications corresponding to acceleration, while paying consideration to the background of law, culture and others that are unique to Japan.

In buildings, escalators are set up as structure with bottom fixed and upper non-fixed style, in order not to restrict the truss deformation. In non-fixed side, Escalator is supported by L-form board, and hanging to the beam of building. Therefore, when building greatly shakes, escalator comes off from the beam of building and may drop. It is necessary to make the behavior of seismic of escalator clear to prevent such an accident. In this study, Analysis model which evaluable the seismic behavior of the escalator has been developed.

This paper presents new methods for elevator group management control system in order to improve transport capability and energy efficiency. We propose a transport capability improvement method for destination floor control system. Feature of this method is detecting the high demand destination floor in advance, and reducing number of stops of car assigned to the floor. In addition, we propose an energy efficiency improving method for elevator group management control system. Features of this method are (1) predicting trajectories of all cars considering of risk of large electric and mechanical losses in future, (2) reducing these losses over from present to the future, and (3) balancing between energy efficiency and passengers' waiting time depending on predictive energy efficiency. The effectiveness of these methods are evaluated by computer simulations.

A Support Vector Machine (SVM) is applied to discriminate disturbances during operation of an elevator door such as draft and a caught passenger. The SVM with a soft margin is designed with priority on detection of passengers for safety. Moreover, Fast Fourier Transform (FFT) is also utilized in the SVM for robust discrimination of a disturbance with an unknown time of occurrence. As a result, the SVM achieves nearly 100 % discrimination rate of human factors while achieving about 80 % discrimination rate of draft.

The earthquake load acting on the equipments of an elevator has been considered in the case of intensity calculation. However, when the resonance phenomenon is occurred to an elevator cage and counter-weight hang by wire ropes, the earthquake load acting on the equipments has not been clarified. In this study, we investigated the earthquake load, through simulation analysis for a dynamic model of an elevator. This paper describes analysis method and the simulation results of the earthquake load. As the results, the earthquake load can reach about 30% of static load at the maximum.

In an elevator system, if the machine or pulleys (sheaves) have some faults, the vibration will occur to the car. However, it is not easy to investigate the quantitative relationship between cause and result. In this report, we construct a dynamics model and clarify the relationship between the vibration of the car and the amount of disturbance caused by the core dislocation of the encoder and torque ripple of the motor through some experiments and simulations.

The vibration to occur in elevator traction machine may cause the vibration noise in the living room in the neighborhood. In this paper, We tried vibration properties analysis of the trestle of traction machine using the operational mode analysis for the purpose of the transmission reduction to the building of vibration. We confirmed that the mode analysis of the trestle of traction machine under the actual machine operation was possible. In addition, we confirmed the improvement of the vibration transmission characteristic to the building by the structure change plan by an experiment and confirmed the effectiveness of this technique.

In recent years, high-rise buildings more than 500 meters height have been built in the Middle East and China. Elevators in such high-rise buildings have long control cables and that causes weight of cables heavy, and the load on the elevator system becomes the greater. Non-contact power supply technology to the car power supply is one of the ways to resolve the problem because it can reduce the weight of control cables. In this paper, we propose a non-contact power supply system configuration that combines the power storage device as suitable for elevators. Furthermore, we show the outline of the prototype in order to verify the feasibility of the proposed system.

With the increase in the number of elevator installation, it is important that the accuracy inspection and work efficiency are improved. In this study, in order to develop a remote maintenance inspection system of wire rope for structure, an inspection device was first mounted for evaluating structural integrity and an elevation mechanism (probe climber) was fabricated which was capable of even vertical automatic movements. This study considers the detection accuracy after configuring a sensor system of Giant Magnetic Resistance sensor-array which is more compact and accurate in detection than conventional products describes the evaluation results through experiments for identifying the locations of damage in conjunction with a drive control system of the automatic elevation device. We did experiments probe climber that elevates the wire rope with five concentrated damages to 50cm interval. As a result, it was able to identify the locations of damage and detect concentrated damages.

An overview of the "voice tweet system" and its possible use cases are described. The "voice tweet system" is developed to support voice communication among workers of what we call "action-oriented intellectual services". In the "action-oriented intellectual services", workers have to move around the work fields, perform both of physical tasks and information processing tasks, in the same time. The conventional IT (Information Technology) systems and devices however, are fundamentally designed for desk workers, so there are strong mismatch between "action-oriented intellectual services" and conventional technologies. Therefore we have developed the "voice tweet system" to overcome this serious gap. This system can be utilized in multiple fields including machine maintenance tasks, medical tasks, and health care tasks. This work is an implementation based on the original research project done as a joint research project between Toshiba corporation, Shimizu corporation and Japan Advanced Institute of Science and Technology as a national project supported by JST/RISTEX from October, 2010 to September, 2013.

This study is concerned with the dynamic modeling and simulation for the elevator rope vibration coupled with building vibrations excited by external forces such as earthquake and gusty wind. To this end, the extended Hamilton's principle was employed to cope with time-varying dynamic problem. The kinetic and potential energy expressions for the main and compensating ropes and building were derived and inserted into the Hamilton's principle. As a result, the dynamic model suitable for numerical simulation was derived and implemented by MATLAB code. Numerical simulations were carried out under various scenarios of elevator operation. Simulation results show that the vibration of the compensating rope becomes concern when the cage is moving up. To verify the theoretical prediction, an elevator simulator consisting of building and elevator rope is being developed.

In recent years, due to the increase of the height of the high-rise buildings, elevators become indispensable facilities. Consequently, during earthquakes, as natural periods of a building and an elevator system get close, the movement of the elevator ropes, the compensating ropes and the control cables become important. Moreover, when the ground motion becomes longer, the ropes may hit the wall of the shaft and cause damage to the equipment. In such case, the elevators have emergency stops. However, during the time required for the restoration of the elevators, the building's functions become unavailable. Therefore, to grasp the motion of the elevator's rope during an earthquake is important. Several manufacturers have used this kind of program in order to evaluate the response of their own elevator systems, but comparisons between all these results are difficult. For this research, the aim is to make the analysis program usable by each manufacturer. In this paper, consideration of the sheave mass, the displacement of the elevator's rope of time when cage going up and down is computied by the response of the top of the high-rise building, then examining for the displacement of the elevator's rope during an earthquake.

Elevator system has various safety devices for safe travel. The overspeed governor is one of the safety devices and connected to the elevator car through governor rope. When it detects the excessive velocity of the car, it stop operation of the elevator. In the case of the governor rope is shaken by car vibration, the circumferential velocity of the governor might become higher than car velocity and then elevator car stops suddenly. In previous study, governor and governor rope were modeled by multibody dynamics and good simulation results were obtained for short path elevator. In this study, the model was improved in order to adapt for running along the long path.

In the elevator installed in a high-rise building, the natural vibration of a building is more closer to the rope an elevator for a skyscraper. A building sway caused by the long-period ground motion or a strong wind makes the ropes of an elevator resonate and the rope contact to or connection to the apparatus attached to the wall of the hoist-way. This paper will introduce the method of the building sway transmitting to the rope deflection. The building sway in which an elevator is installed is always observed, and optimal operation is performed, securing safety from the length of the rope which can be found from the amount of building sway, and the cage position of an elevator using the technology of presuming the amount of rope deflections.
