IPC: H01S5/40
Filed: 1988-02-25
Abstract: PURPOSE:To apply an APC to discrete lasers of a multi-beam laser by providing a temperature detector which outputs a signal output for controlling a driving current value from an automatic output control (APC) circuit fed to a laser diode. CONSTITUTION:A control circuit 321 drives laser diodes 311-313, and is so driven as to obtain optical outputs corresponding to the inputs to input terminals 301-303. A temperature sensor 322 monitors the case temperatures of the diodes 311-313, and applies cage temperature information to a control circuit 321. Normally, temperature dependency is provided in the relationship between the driving current and the optical output of the diodes, and it is necessary to increase the driving current by approx. 1mA per 1 deg.C of temperature rise so as to maintain the optical output constant. Since the characteristic for compensating the property is incorporated in the circuit 321, the diodes 311-313 obtain optical outputs corresponding to the inputs of the input terminals 301-303 irrespective of the case temperatures of the lasers.

Title: Drive force transmission
Inventor: SAKAI TOSHIBUMI
IPC: F16D25/063
Filed: 1988-02-25
Abstract: PURPOSE:To prevent trouble in ABS(anti-lock brake system) control by providing a frictional plate rotatable through frictional function with respect to a blade in the housing and arranging a means for communicating between high and low pressure sides in a pressure chamber only at one rotary and position of the frictional plate. CONSTITUTION:When brake is applied, torque flows from rear wheel side to front wheel side in reverse input characteristic and a blade 42 rotates relatively to a rotary housing 21 through relative rotation between front and rear drive shafts 15, 16. Consequently, a frictional plate 45 makes accompanied rotation through frictional function with respect to the blade 42 thus communicating a pair of adjoining communication holes 50A, 50B. Since pressure leaks from a pressure chamber 43 through the high pressure side communication hole 50A and a communication groove 48 to the low pressure side communication hole 50B, pressure in the pressure chamber 43 lowers thus decreasing torque to be transmitted from the drive shaft 16 to the drive shaft 15. Consequently, slippage of a multi-board clutch 25 is allowed thus causing no trouble in ABS control.
