Title: Amplifier circuit
Inventor: SHIROGANE TATSUO
IPC: H03F3/45
Filed: 1984-05-16
Abstract: PURPOSE:To operate an amplifier circuit with a low voltage stably well by providing a variable current source which changes the bias voltage of a transistor (TR) in accordance with the change of the current amplification factor of the TR of the first stage.

Title: Soft-touch operating mechanism of tape recorder
Inventor: TOMITA SEIJI
IPC: G11B15/10
Filed: 1980-07-15
Abstract: PURPOSE:To give a reverse operation to the normal state to a soft-touch operating mechanism and thus secure a reset to a nonoperation state, by providing a changeover means that supplies the power of battery in adverse polarity to a motor through a manual operation. CONSTITUTION:If the power of a battery is exhausted to cause an extremely slow rotation of a cam gear 513, a button 83 is pushed to reverse the polarity of the battery voltage applied to a motor 55. Thus the motor 55 has the adverse rotation to the normal state. Accordingly, a cam gear 51 also has the adverse rotation (counterclockwise in the diagram), and thus the load is reduced for the gear 51 less in the counterclockwise rotation than the clockwise rotation owing to the shape of the curved part of the cam 513 and the clockwise energization of a drive lever 59. Accordingly, the load of the motor 55 is also reduced. As a result, the gear 51 can be reset to its original position when the battery power is exhausted.

Abstract: PROBLEM TO BE SOLVED: To shorten the length of a dental straight hand piece. SOLUTION: A pair of axially symmetric slits 3a, 3a are formed so as to axially extend in a hollow part formed in the distal end part of a rotary shaft 3. A chuck shaft 1 is inserted in the hollow part of the rotary shaft 3 so as to be axially movable therein, and upon chucking, a chuck shaft pressing unit 7 is pressed in the direction of the arrow.
