Title: Ultrasonic motor
Inventor: INABA RITSUO
IPC: H02N2/00
Filed: 1988-10-28
Abstract: PURPOSE:To enable a motor to be driven in a point of maximum efficiency by variably adjusting an applied pressure for obtaining friction force between a stator and a rotor. CONSTITUTION:A connecting pin 7 is not actuated unless an applied pressure is adjusted between a stator 1 and a rotor 2 but actuated when the applied pressure is adjusted. When the connecting pin 7 is actuated, rotation of the rotor 2 is transmitted to a rotor energizing part 6 through a tooth 2a and the connecting pin 7, and an applied pressure adjusting screw thread 6a is rotated to enable a distance to be adjusted between the rotor energizing part 6 and a fixed bed 3. Accordingly, the applied pressure to the rotor 2 can be adjusted. On the contrary, when the connecting pin 7 is not actuated, rotary power of the rotor 2 is not transmitted to the rotor energizing part 6, so that the present applied pressure is maintained without changing the distance between the rotor energizing part 6 and the fixed bed 3. Thus a motor can be driven in a point of maximum efficiency.

Title: Surge absorber
Inventor: IGARASHI TAKASHI
IPC: H01C7/12
Filed: 1989-10-20
Abstract: PURPOSE:To obtain excellent surge absorbing performance, reduce the electrostat ic capacity, and decrease the leak current by providing a groove on the outer periphery electrode face or the inner periphery electrode face of a voltage nonlinear resistance element, and forming a gap on the electrode face of the above element. CONSTITUTION:A gap is provided on an inner periphery electrode 2 face, for example, and the discharge start voltage of the gap can be controlled by the distance (1) of the groove 4 on the electrode 2. When the circuit voltage is lower than the discharge start voltage of the gap, a leak current flows only in a dark current region due to the gap, it is very small, and the electrostatic capacity is decreased because the electrostatic capacity of the gap is low. When the abnormal voltage becomes higher than the discharge start voltage of the gap, the gap is discharged into the short-circuited state, a voltage nonlinear resistance element 1 absorbs the surge voltage, thus the dynamic current can be cut off.

Filed: 1993-11-02
Abstract: PURPOSE:To provide an excellent paper sheet carrying device, which can prevent the lowering of availability factor of a bill receiving/paying device and which can reduce the generation of broken bill to improve the availability factor, by utilizing a part of a DC servo unit as it is, and adding a few number of external-fitting circuits, namely, a bill-carrying-error detecting unit.
