In the vibration analyses for the elevator systems, especially in high-rise buildings, the elevator rope is assumed as an elastic model. There are caused two vibrations in the rope. One is the longitudinal vibration, and the other is the lateral one. Accordingly it is desirable to consider longitudinal and lateral vibrations at the same time. However many conventional works have been carried out with the longitudinal and lateral vibrations separately. This paper proposes a wave transmission model for the behavior of the lateral vibrating rope coupled with the longitudinal vibration. We explain the process of constitution for the analytical model. Furthermore, the validity of proposed model will be shown through some experimental data

Machine-Room-Less Elevator has the structure where a drive system is supported by the rail. So, the vibration generated at the time of an elevator run becomes easy to be transmitted to hoistway enclosure from a rail. For this reason, it needs to be cautious of the problem of generating noise in the room that adjoins by vibration from a hoistway. Then, the simulation technology for predicting the noise caused by vibration generated by elevator run was developed. Furthermore, this simulation performed optimization examination of a suppressing vibration design of elevator structure, and the effect was checked by examination.

In order to relax the impact to the elevator system when the car or counter weight collides with the terminal, the buffers have been installed. In this research, the application examination of a small, cheap shock absorber utilizing plastic deformation to the elevator system is done. Moreover, it proposes the cylinder buckling type buffer as a plasticity shock absorber, and the static characteristic is confirmed by the FEM analysis and the examination. In addition, the buffer characteristic of this shock absorber is confirmed from the dynamic test with impact testing machine, and the utility is confirmed.

Presently elevator industry meets the big change to machine-room-less. We developed a ultra thin thickness lift machine, which used the RV reduction unit and flat motor. This Lift machine (passenger weight is 1ton) thickness is 200mm. And weight is only 270kg. It can be installed in almost gap between car and wall. And control is very easy. We think this machine will be the next machine instead of DD type and we hope to contribute to elevator industry with it.

A high-speed and comfortable riding elevator with ultra-super-high speed of a world maximum speed 1010m/min has been developed. The elevator safety device, which bears the high temperature exceeding 1000℃ by working emergency safety device, was developed and acquired the twin drive control technique for driving a powerful traction machine. An atmospheric pressure control has also been developed in the riding comfort for a high-rise building. Corresponding to increase skyscrapers, the analysis of a rope vibration by the simulation made to accomplish the vibration-control system. These high-tech-items lead to the elevator in the Taipei financial center building of 508m high.

We developed a new screw type elevator that used the screw & nut drive method. It is a system that transports the basket by using the hollow shaft motor for driving device and driving the nut directly along the screw. The screw is hung and fixed on the overhead beam that is located at top of guide rails, and all vertical loads including the basket act on the pit through those rails. By using screw & nut drive method; we could reduce the pit depth from 1200mm (conventional elevators) to 150mm. We also developed exclusive compact hoist-way for the screw type elevator at the same time. It is constructed of several units and the elevator parts, including the basket, can be integrated in those units in the factory before delivery. In this case, the installation at the site can be done in a short time and we can save time and man-power as the result. This hoist-way unit can be applied for small gap such 1.0m heights. As we explained above, screw type elevator has advantages of only 150mm pit depth, compact hoist-way cross-section, applicable for small gap and quite easy installation. So screw type elevator can be installed even if the site has certain difficulties for installation and it can promote the modernization for barrier free access.

There are many outdoor type observation elevators that have glass panel cage and no hoist-way wall for enjoyment of panorama at Hotels and High-rise buildings in overseas. We have studied and developed several countermeasures for the environment-the wind, rainwater and so on. These high-technology features are employed in an elevator installed in the Izumi Garden Tower at Roppongi-1chome that has 17person capacity and 360m/min rated speed.

From the end of 2000,as the beginning of the project, we installed over 100 escalator units on the subway Oedo line. Due to the depth involved we had to develop supplementary devices to support our installation. This process and the problems involved are outlined in this report

In this paper, author evaluated the influence on the human body from the physical quantity of vibration received from rides and the response (psychological/physiological response) of the human body, from the ergonomics point of view. Rides are roughly classified into two types. One performs mainly a linear running motion which includes elevated facilities such as roller coasters. The other performs a rotary motion by power about the plumb or variable axis which includes merry-go-rounds, Ferris wheels and the like. As the index for studying the influence on the human body, author adopted the SD method (Semantic Differential method) for analyzing feeling, impression, etc, due to motion of the ride in respect or psychological response, and the electrocardiogram and the respiration exercise in respect of physiological response.

Since airships are an environmentally-friendly, safe and energy-saving vehicle, they are the most suitable vehicles to meet the modern social needs. If small airships with highly enhanced maneuverability can be realized, they will satisfy people's desire to fly freely in the air without anxiety. However, conventional propulsive systems have little possibilities to improve maneuverability. Hence, we try to adopt cycloidal propellers on airship as a new propulsive system. Cycloidal propeller is a type of propulsion system to generate thrust by controlling attack angles of blades rotating constantly. By adjusting the vehicle's gravity center and the buoyancy center as close as possible, we can perform somersault around the center of gravity of the airship.

In recent years. Enlargement of stations, airports, and commercial facilities has increased the traveling distance of people. With this trend, more and more expectations are put on the moving walks as a means of horizontal transportation Conventional moving walks run at a constant speed of 30 or 40m/min, so there is a strong demand for shortening of traveling time. Under such background, we have developed an accelerating moving walk SPEEDMOVE with a tread running about twice the speed of the enter and exit sections in the middle section and as slow as the speed of conventional constant speed moving walks at the enter and exit sections. In this system, a thin flat belt (groove-less) is adopted, and passengers are carried on multiple different-speed tread belts arranged in a straight line. The tread belt speed in the middle section reaches 72m/min.
