Title: Optical recording and reproducing device
Inventor: TESHIROGI KAZUHIRO
IPC: G11B7/085
Filed: 1986-05-12
Abstract: PURPOSE:To control a tracking stable after the transfer of an optical head, by measuring a time required from a position separated by a micro distance DELTAx from a targeted position to the targeted position, and turning on a tracking control after deciding a stable pull-in time of the tracking. CONSTITUTION:The arrival of a transfer mechanism at this side by the micro distance DELTAx of the targeted position is decided by a comparator 11, and a time T10 is started to measure, and the arrival of the mechanism at the targeted position is decided by a comparator 14. And the time T10 required for the transfer for the micro distance DELTAx, and a time T0 possible to pull in the tracking stably at that time, are compared, and when it is T10>=T0, the tracking control is turned on. When it is T10<T0, the measurement of a time T20 is started, and the arrival at the position separated by the micro distance DELTAx from the targeted position is decided by the comparator 13, and the arrival time T20 at the targeted position, and the time T0 are compared, and when it is T20>=T0, the tracking control is turned on. Also, when it is T20<T0, the above operation is repeated until a time Tn required for the transfer of the mechanism for the micro distance DELTAx exceeds the time T0. In such a way, the tracking can be controlled stably.

Abstract: PURPOSE:To make it possible to read the precise engine state signal even when the voltage of a battery is low, by synchronizing the engine state signal with the rotation of an engine and picking up the engine state signal at a crank angle when the voltage of a battery is high. CONSTITUTION:When the engine is controlled digitally in accordance with the engine signal read from a sensor for detecting the state of the engine, the output of the sensor is synchronized with the rotation of the engine, and the engine state signal is picked out at a crank angle when the load on the engine is low, for example, at around the bottom dead center, and the voltage of the battery becomes high. Thus, a stable constant voltage Vc can be obtained, and analogue- to-digital conversion values for precise engine cooling water temperatures and suction air temperatures can be obtained. Therefore, the running state of the engine at its start or after the start can be retained properly and good starting performance and engine operation performance can be obtained.
