Title: Semiconductor circuit
Inventor: ASANO MASAMICHI
IPC: H03F3/50
Filed: 1988-07-29
Abstract: PURPOSE:To perform quick operation by providing a level holding means which forcibly sets the output voltage of a MOS driving circuit to a value lower than a supply voltage after boosting the gate voltage of a TR of a MOSFET driving circuit. CONSTITUTION:MOSFETs 7-10 and 12-15 constituting twostage delay circuits 50 and 60 are connected to a circuit consisting of MOSFETs 1-6, and further, voltage level compensating MOSFETs 11 and 16 are connected there. When an input (d) is changed from '0' to '1', charging of an output terminal D is started by the FET 1. An output terminal A rises from '0' to '1' after the delay of the circuit 50, and this level is applied to the gate of the FET 5 of a buffer 40. The FET 11 forcibly sets the value of the output terminal D to a value lower than the supply voltage. An output Dout of the buffer 40 outputs '1'. When the input (d) is changed from '1' to '0' and the output Dout outputs '0', said operation is performed also by voltage rise of an output terminal D'. Thus, quick operation is possible and the output short current is suppressed.

Title: Protecting device of magnetic head for magnetic disk device
Inventor: OGAWA TOMIHISA
IPC: G11B5/596
Filed: 1982-10-29
Abstract: PURPOSE:To protect a mgnetic head based on an information signal by converting the variance component of the position detection signal of the magnetic head into a DC signal to compare this DC signal with the reference value, and performing said protection of the head in case the amplitude of the fluctuation component of the position detection signal shows an abnormal level. CONSTITUTION:If a servo system is oscillated due to the generation of some fault, the amplitude of a position detection signal is increased Vs as shown in a figure A. This is due to the fact that a magnetic head is vibrated by the oscillation of the servo system. The signal Vs is converted into a DC signal corresponding to an AC component which has increased its amplitude via a DC preventing circuit 2 and a rectifying circuit 4. As a level of the DC signal is high, the integration output signal VA of an integration circuit 6 has a higher level than the refernce voltage VR. As a result, a comparator 8 delivers a signal of a logic level ''H'' and an oscillation detection signal VB informs a fault of the servo system. The signal VB is applied to a protecting device. This protecting device retracts the magnetic head to the surface of a magnetic disk.
