Title: Optical disk reproducing method and optical disk device
Inventor: YAMAGUCHI HIDEO
IPC: G11B7/095
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To stably read out information from an optical disk. SOLUTION: An inclination of the optical disk is detected by a tilt sensor 13 provided in an inner circumference and a tilt sensor 14 provided in an outer circumference. An inclination of each part of the optical disk is calculated in direction and degree from a result of detecting this inclination in inner circumferential and outer circumferential positions (addresses) so as to be predictive. Thus, by moving an objective lens 3 for the purpose of reproducing information at an address, and at the same time, by driving a tilt servo motor 10 in accordance with an inclination in the position at these addresses based on the predicted calculation result, a deviation from perpendicularity between an optical axis of the objective lens 3 and a reflecting surface of the optical disk is corrected, and hence the information can stably be read out of the optical disk.

Abstract: PURPOSE:To reliably lubricate a sliding face such as the end plate section of a rotary scroll by forming an oil sump section storing the oil reclaimed by an oil dropping plate on a fixed scroll and providing a discharge hole protruded above the oil surface of the oil sump section. CONSTITUTION:An oil dropping partition plate 24, the end section 25 of which is arranged above an oil sump section 23 formed on a fixed scroll, is provided inside the upper shell 22 of an enclosed container 10.

Title: Signal processor
Inventor: IENAKA MASANORI
IPC: H03G3/34
Filed: 1984-02-10
Abstract: PURPOSE:To reduce power consumption with a signal processor by actuating a means which detects the presence or absence of an input signal for each fixed interval decided by the duty ratio of a control signal and applying a power supply to the signal processor when the input signal is supplied to a circuit having the specified actuation. CONSTITUTION:The signal of a line l6 is supplied to the gate of an NMOSTRQ1 via resistance R2. The TRQ1 is turned on when at least one of a control signal Pc and the signal of the line l6 has a high level. Thus a current path is formed for the TRQ1 and bipolar TRs Q2-Q5 respectively. Then the TRQ5 and TRs Q6-Q8 as well as the TRs Q9 and Q10 form current mirrors respectively and therefore TRs Q6-Q10 are turned on. While the TRs Q5-Q10 function as a constant current circuit. Thus a reception device can work just in an extremely short period of time during which the signal Pc is set at a high level. This reduces greatly the power consumption of said reception device. In addition, the workable period of said reception device can be freely set by the duty ratio of the signal Pc.
