Title: Compensating circuit for magnetic disk device
Inventor: HIBINO YOZO
IPC: G11B21/10
Filed: 1986-03-12
Abstract: PURPOSE:To improve the stability and the quick-response of a follow-up control to a target track by putting a notch filter and a low pass filter into the loop of a compensating circuit. CONSTITUTION:A compensating circuit is composed of a read lag filter 3 to stabilize a control system, a notch filter 4 to compensate the resonance point of a mechanism system, a low pass filter 5 to remove a high frequency noise from a deviation signal showing the position dislocation of a magnetic head from a target track and a demodulating circuit 6 to generate the deviation signal from a servo pattern on a magnetic disk. To suppress the peak of a gain at the magnetic vibrating point of the lowest frequency, the notch filter 4 is putted in which a gain has a sharp trough opposite to this. Since the phase is delayed without fail at the low frequency side of the notch filter 4, the resonance frequency of the low pass filter 5 is made coincident with an antiresonant frequency applied to the frequency side higher than the resonance frequency of the lowest frequency of the mechanism system.

Filed: 1989-03-03
Abstract: PURPOSE:To form a minute pattern which can be applied to a substrate that is integrated at a high density by performing slant vapor deposition on the substrate, thereafter removing a resist pattern, and lifting off a material which is formed on the resist pattern by vapor deposition. CONSTITUTION:A hole 5 is formed so that it advances downward from the side of the surface, curves in its halfway and then further advances downward. A resist pattern 4 having the hole 5 is formed on a substrate 1. Then, etching is performed for the substrate through the resist pattern 4. A metal is formed by a slant vapor deposition method from the slant upper direction with respect to the substrate 1. Thereafter, resists 2a and 2b are removed. An unnecessary metal film 3b which is formed on the resists 2a and 2b is lifted off. Thus a minute pattern comprising a metal film 3a is formed on the substrate 1. Therefore, the metal film 3a formed on the substrate 1 is formed at a place separated from the resist 2a and the metal film 3b on the resist 2a. In this way, the unnecessary metal film 3b can be readily lifted off by removing the resists 2a and 2b. Thus, the minute pattern of the material formed by the vapor deposition can be formed on the substrate.

Title: Analog switch circuit using mis field effect transistor
Inventor: UCHIMURA KUNIHARU
IPC: H03K17/687
Filed: 1980-04-21
Abstract: PURPOSE:To obtain a high-precision function of switching by permitting the circuit to turn on input-output terminals when a switching signal applied to the source of MISFET is at ''1'' and to turn off when at ''0''. CONSTITUTION:At source S, MISFETM is applied with switching signal SW of ''1'' or ''0'' from terminal 3 of control circuit K. When signal SW is at ''1'', voltage VON turning on FETM is applied to source S from input terminal T1 through circuit K, setting an on-state between input terminal T1 and output terminal T2. When signal SW is at ''0'', FETQ2 is turned on to apply voltage VOFF, turning off FETM to source S of FETM from circuit K, and consequently FETM is turned off to set an off-state between input terminal T1 and terminal T2. Thus, the high- precision switching function is obtained without developing across load 2 at terminal T a fluctuating voltage which may cause noise.
