Title: Brake, lock and open holding mechanism for elevator door
Inventor: JAMINET JEROME F
IPC: B66B13/08
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain force keeping a brake and closing/opening of an elevator door, satisfying safety standards, independent of a linear electric motor, in relation to an elevator door operating device. SOLUTION: A friction material brake pad 11 is pressed against a surface of a door hanger 24 by a push type solenoid 19, and when no brake action is required, a brake shoe is pulled to be separated from the door hanger by a spring means. When a door power source is supplied, always a current is carried in the solenoid 19, and in the case of moving a door, always resultant force is placed in a neutral condition by force generated by a current supplied to a linear electric motor. When the power source is tripped during operation of the door, an instantaneous brake is executed by instantaneously operating the solenoid 19.

Title: Electric double-layer capacitor
Inventor: ANDO KAZUO
IPC: H01G11/22
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To secure the continuity between collector lead and an electrode terminal even if a polarization electrode is increased and the capacity of a capacitor is increased by using a collector lead lamination body as a connection part, and connecting the connection part to the electrode terminal via a junction part for integrating the collector leads of the collector lead lamination body. SOLUTION: A collector lead lamination body 8a where a plurality of collector leads are laminated for the same pole is used as a connection part 19, and a junction part 21 is formed at one portion of the connection part 19 by ultrasonic diffusion junction. A plurality of collection leads are lightly joined by the junction part 21. Then, a projection 18 of the electrode terminal is inserted into a through hole 22 that is formed at the center of the junction part 21 for welding. In this manner, the junction part where each collector lead is integrator by ultrasonic diffusion junction is welded to the electrode terminal instead of directly performing the ultrasonic diffusion junction of the electrode terminal and a collector lead lamination body 8a as in the above, thus securing improved continuity even if the capacity of a capacitor is increased by increasing a polarization electrode.

Title: Vehicle travelling speed control device
Inventor: YAMANE YUICHI
IPC: F02D11/04
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To improve the operational safety of the industrial vehicles such as fork lift trucks during operation within the plant, etc., by enabling the control of vehicle speed to a predetermined speed limit by providing a first lever connected to the throttle lever of the injection pump and a second lever which controls the turning angle of the first lever. SOLUTION: In this vehicle speed control device, an accelerator pedal 2 is connected to a shaft 4 and a first lever 6 via a spring 5 attached to a spring hook 3a. When the accelerator pedal 2 is operated to the maximum stepping distance, the first lever 6 is turned via the spring 5. The turning angle of the first lever 6 is controlled by turning a second lever 7 to a predetermined turning angle by means of an actuator 30. If the second lever 7 is turned to a predetermined turning angle, in other words, operation of the accelerator pedal 2 to the maximum stepping distance only causes elongation of the spring 5 and turning of the first lever 6 is prevented. Therefore, the operating range of a throttle lever 20a is limited and the traveling speed of the vehicle in the plant is controlled to a predetermined speed.
