IPC: H01L41/09
Filed: 1989-10-13
Abstract: PURPOSE:To reduce the consumption of expensive wear resistant material for making the cost down feasible by a method wherein clamping members are composed of a material in the different kind from that of a basic material to be used as the clad material on the inner surface of the clamping members. CONSTITUTION:An inner surface of almost cylindrical base material (m) is clad with a metallic material (n) in different kind from that of the basic material (m) so as to form the inner surface (q) of clamping members k, l. As for the raw material of the base material (m), a highly elastic metallic material such as phosphor bronze etc., is applicable while as for the clad material (n), a high wear-resistant material such as silver is applicable. Accordingly, the high wear-resistant material will suffice to be used only for the inner surface of the clamping members k, l thereby enabling the consumption of expensive material to be reduced. Through these procedures, the wear resistance can be enhanced without increasing the cost by using the expensive material such as silver as the clad material on the inner surface of the clamping members.

IPC: B60K17/30
Filed: 1985-11-29
Abstract: PURPOSE:To improve the driving efficiency and to prevent occurrence of noise by changeably providing a wheel frame direction, bearing a wheel rotatably, and controlling the rotation of a motor for rotating the wheel according to the changing angle of the wheel frame at the time of changing the direction. CONSTITUTION:Upon operation of a motor 7 for rotating a wheel, the wheel 1 will rotate to travel an object 13. While, upon operation of a steering motor 8, a wheel frame 3 will rotate around an axis. Consequently, the direction of the rotary face of the wheel 1 will change to perform direction change in that direction. Here, the rotary angle of the wheel frame 3 is detected by a potentiometer 15 to feed a signal to a control circuit 16. Consequently, the motor 7 for rotating the wheel will rotate to enable directional change of the wheel 1 without slippage. As a result, a bevel gear for driving the wheel 1 is not required, thereby the entire apparatus can be simplified and thus improving the efficiency and eliminating the noise.

Filed: 1984-12-20
Abstract: PURPOSE:To decrease the temperature dependancy by using two transistors (TRs) whose collectors are connected to a common connecting point between a reference voltage generating terminal and a constant current source via a resistor. CONSTITUTION:An emitter of a TRQ7 acting like a constant current source is connected to a reference voltage terminal Vref, and collectors of the TRs Q3, Q4 are connected to the common connecting point via the resistors R1, R2 respectively.
