Title: Free wheel type clutch
Inventor: KURAUSU KEMUPUFU
IPC: F16D41/12
Filed: 1990-07-06
Abstract: PURPOSE: To shorten a response travel by oscillating both blocking pawls through control rings isolated from each other, and allowing the control rings to turn to each other in relation to clutch parts supporting the blocking pawls respectively. CONSTITUTION: When an outer member 2 is turned in n-direction, a blocking pawl 4 is turned from a disengaged position to an engaged position to be brought into contact with a supporting slot 18 in an inner member 3 by sliding friction between a friction ring 34 and a control ring 32. On the other hand, since a blocking pawl 5 is arranged on opposite direction to the blocking pawl 4, the blocking pawl 5 is separated from a supporting face of the supporting slot 18. In the following stage, the blocking pawl 4 is moved into a receiving position. Thus the blocking pawl 5 radially departs from the supporting slot 18 in the inner member 3. As a result, a response travel when torque is switched from one direction of rotation to the other direction of rotation can be shortened.

Title: Semiconductor laser driver
Inventor: SAKURAI TATSUAKI
IPC: G11B7/125
Filed: 1990-07-05
Abstract: PURPOSE:To prevent flow of a current which is not controlled, to eliminate an abnormal light emission and to protect a semiconductor laser against deterioration by providing a quasi-signal input circuit and controlling by ON, OFF of first and second switches at a suitable timing. CONSTITUTION:A power source 7 is turned ON in a state that first and second switches 9, 12 are opened at the initial time of turning ON the power source. Then, when a semiconductor laser 1 actually emits a light, the switch 12 remains opened, and the switch 9 is closed. Thus, a voltage gradually raising through a slow-starter 8 is applied to the anode of the laser 1. In this case, the input of a current controller 5 constitutes a quasi-signal input circuit. A GND level signal is applied to a resistance circuit 11 as a quasi-signal reception signal. When the laser 1 is deenergized, the switch 12 is previously opened to set the input of the controller 5 to a quasi-reception signal, and then the switch 9 is opened. Thus, a current which is not controlled does not flow to prevent emission of an abnormal light.
