Abstract: If an intermittent oscillation pulse in a case in which the power consumption in the standby state is reduced at the maximum is supplied to a connection point from an output port of a microcomputer through a capacitor and a resistor, a DC component of the intermittent oscillation pulse is removed and is then supplied to the connection point. At this time, even when a voltage of the connection point becomes larger than a power supply voltage of the microcomputer, since a current does not flow backward from the connection point to the microcomputer, the microcomputer is normally operated. As such, the microcomputer is normally operated, so that the intermittent oscillation pulse is effectively supplied to the connection point. Thereby, a transistor is intermittently operated, the oscillation circuit intermittently performs oscillation operation, and the power consumption in the standby state is reduced.

Abstract: A flexible flat cable and an apparatus for assembling the flexible flat cable are provided. The flexible flat cable has a conductive wire group including conductive wires disposed parallel to each other and arranged in a synthetic resin cover, in which both end portions and of the conductive wire group protrude outward from the end edges of the cover, and a pair of synthetic resin reinforcing plates are fixed to areas extending from one surface at the respective end portions of the cover through one surface at the respective end portions of the conductive wire group. One of the reinforcing plates includes a hollow square reinforcing plate formed by providing a through hole at the center of a reinforcing plate, and the other reinforcing plate includes a central reinforcing plate extracted from the hollow square reinforcing plate.

Abstract: A disk reading apparatus for reading data recorded on a disk medium is disclosed. The disk reading apparatus comprises a motor for rotating the disk medium, a vibration sensor section for detecting vibrations generating inside the disk reading apparatus and for converting the vibrations into a signal, a binarized signal generation section for extracting only a frequency component corresponding to the rotary speed of the disk medium from the signal outputted from the vibration sensor section, and for outputting a signal in which a binaraization is performed, a vibration judgement section for measuring a period of the binarized signal outputted from the binarized signal generation section and for outputting a vibration detection signal when the period of the binarized signal corresponds to the rotary speed of the disk medium, and a rotation control section for lowering the rotary speed of the disk medium when the vibration detection signal is inputted.
