IPC: G11B7/09
Filed: 1980-10-31
Abstract: PURPOSE:To prevent the influence due to secular change of parts, by moving a position of a photodetector to an optimum position in accordance with the magnitude of a signal of the photodetector. CONSTITUTION:A light beam emitted from a semiconductor laser 31 is made incident to a photodetector, and is inputted to a photodetector position control part 39 through a recording signal reproducing part 36, a rectifying circuit 37 and an A/D converting circuit 38.

Abstract: PURPOSE:To make a diagnosis of every circuit surrounded with shift registers of one circuit block or blocks by selecting a shift path arranged for every circuit block while circuits in a data processor are sectioned into circuit blocks. CONSTITUTION:When a selection signal e2 is a (1) and selection signals e1 and e3 are (0)s, the output 120 of an AND circuit 20 is a (1) and the output hold signal of an AND circuit 26 is a (0), so that a shift register 6 holds itself in readiness for shifting operation.

Then, a shift mode signal (d) is held at a (0). As a result, the output of an AND circuit goes down to a (0) and in this state, a synchronizing signal a2 is supplied to a shift register 7 by one pulse, thereby diagnosing combinatorial logical circuits 9 and 10 on the basis of the diagnostic data set in the shift register 6.

Inventor: NAGAOKA JIROU
IPC: H02P7/288
Filed: 1977-12-21
Abstract: PURPOSE: To reduce the power consumption of a controlling transistor by stepwisely switching a power supply voltage.  
     CONSTITUTION: When feeding a tape at high speed, a switch SW1 is closed, transistors Tr2, Tr3 are not conducted, a transistor Tr4 is conducted, transistors Tr5, Tr6 are not conducted, and the base voltage of a transistor Tr1 is increased in the state that the voltage V 1  is produced from a power supply. As the base voltage of the transistor Tr1 is increased, the emitter voltage of the transistor Tr1 is accordingly raised to start rotating of a motor. When the emitter voltage approaches the voltage V 1  of the power supply, a zener diode ZD is conducted. Accordingly, the transistors Tr6, Tr5 are conducted to increase the power supply voltage to V 2 . Thus, the consumption of the power of the controlling transistor is largely reduced by stepwisely switching the power supply voltage.

During rich air-fuel composition excursion, the spark advance is instantaneously reduced, and on the other hand, during lean air-fuel composition excursion, the spark advance is instantaneously increased. Thus, desired engine efficiency and operational easiness of vehicle can be obtained.
