Abstract: PURPOSE:To easily adjust a damper through operation from outside by providing a block disposed vertically movably at a position of axis of a container and capable of freely entering liquid or powder and an operating member for vertically operating this block from the outside of the container. CONSTITUTION:Liquid 8 or powder is stored in a storage part 7 of a container 6 coaxially attached to an upper part of a motor 1. Thus, vibration generated by the motor 1, namely, energy of a mechanical resonance system is absorbed by the liquid 8 or power to reduce vibration. When a block 9 disposed in the container 6 is moved downward to enter the liquid 8 or powder, level of the liquid 8 or powder in the storage part 7 having an upper diameter larger than a lower diameter rises and accordingly, the diameter thereof becomes large. Therefore, inertial force changes, and an energy absorbing condition based on the liquid 8 or powder changes so as to meet the adjustment as a damper.

Title: Information storage device, and method and device for controlling same
Inventor: OKADA YUTAKA
IPC: G11B21/10
Filed: 1990-11-05
Abstract: PURPOSE:To enable scattering adjustment of a machine system to be simplified by storing control information for adjusting the machine system or an electrical circuit system in a storage device and then reading it when starting to control. CONSTITUTION:A target head speed corresponding to the number of tracks is output from a processor according to a command from a main computer. Signal from a servo disk is demodulated and a position is obtained and then it is subjected to differential calculation, thus obtaining head speed. A motor is controlled by a difference signal with a target speed, thus enabling the target speed to be maintained. Control information of a machine electrical system is memorized in a disk, is reproduced and amplified, and then is sent to the processor. A notch filter is controlled by information of a resistor 1, frequency is varied, and compensation is performed even if a resonant frequency such as an arm scatters for each disk. Information for compensation for an external force is memorized in a register 2 and the outer force is compensated for each disk. Information for control is read from the disk at the time of starting and is transferred to a servo system register or a memory for waiting. This configuration allows tracing accuracy to be improved and amount of offset to be reduced.

Abstract: PURPOSE: To enhance the activation rate of zinc by eliminating heat treatment and removing thermally damaged layers without increasing the number of production steps. CONSTITUTION: Major parts (N-type clad layer 13, active layer 14, P-type clad layer 15, etc.) are formed on an N-type GaAs substrate 11 by a metal organic vapor phase epitaxial growth system and a channel groove 22 is made by selective etching. It is then heat treated in a preliminary chamber using a liquid phase epitaxial growth system comprising a preliminary chamber for carrying out heat treatment in an inert gas atmosphere, and a chamber for forming a semiconductor layer by liquid phase epitaxial growth. Subsequently, a P-type clad layer 19 and a P-type cap layer 20 are grown in the chamber. Since a liquid phase regrowth is carried out, the most superficial surface (heat damaged layer) 23 subjected to thermal damage through heat treatment for activating zinc is melt back.  Furthermore, since a liquid phase epitaxial growth system comprising a preliminary chamber and a growth chamber is employed, the heat treatment step and the regrowth step can be carried out continuously in a same liquid phase epitaxial growth system.
