Title: Optical pickup device
Inventor: NISHINOMIYA MASANOBU
IPC: G11B7/125
Filed: 1990-08-15
Abstract: PURPOSE:To suitably control the quantity of light by providing a photodetector arranged in an optical path from a deflecting prism to an objective lens so as to photodetect the light flux, and a control means to control the driving current of a semiconductor laser element based on the photodetection signal of this photodetector. CONSTITUTION:A deviation signal ER corresponding to deviation between a reference value VR and a photodetection signal SR is outputted from a differential amplifier 11 and applied to a semiconductor laser element driving circuit 13 to control the driving current of a semiconductor laser element 1. The circuit 13 controls the magnitude of a driving current ID impressed to the element 1 in a direction where the deviation signal ER is zero. When the quantity of light made incident to an objective lens 5 is lowered by sticking dirt onto optical parts, the quantity of light made incident to a photodetector 7 is lowered as well and therefore, a signal SR is lowered. Thus, the value of the signal ER outputted from the amplifier 11 becomes a value corresponding to the reduction in the quality of light made incident to the lens 5, and the circuit 13 changes the driving current ID so that the quantity of light made incident to the lens 5 can be coincident to a reference value.

Title: Input circuit
Inventor: NAGANAMI TORU
IPC: H03K19/00
Filed: 1991-08-27
Abstract: PURPOSE:To reduce the number of required MOS transistors(TRs) to a half and to suppress the increment of a semiconductor chip area to its minimum by providing this input circuit with a pseudo latch circuit for latching either one of input level signals of 'H' and 'L' levels. CONSTITUTION:If a noise is mixed between a power supply VC and ground G at the time of outputting data, when the gate/source voltage VGS of an NMOS TR Q12 in an inverter circuit 11 exceeds a threshold voltage VT the TR Q12 is made conductive. Thereby the drain potential of the TR Q12 is turned to '0' level, and a '0' level output is inverted to '1' level, generating malfunction. However when a '0' level control signal phi1 is inputted to the pseudo latch circuit 1 at the timing of noise mixing, '1' level power supply VC is applied to a node A through the PMOS TRs Q11, Q12 to suppress the malfunction. Thus the number of required MOS TRs can be reduced to a half and the increment of the chip area can be suppressed to a minimum.
