Title: Head speed control system
Inventor: NOMURA HIDEO
IPC: G11B21/10
Filed: 1986-04-18
Abstract: PURPOSE:To reduce the acceleration for switching from speed control to position control without extending the access time by exponentially functionally reducing the absolute value of the acceleration of the head speed according as approaching a target position track if the head position is a prescribed length or shorter distant from the target position track. CONSTITUTION:The exponential function curve, where the head speed approaches a maximum speed line l1 gradually and is sufficiently reduced when a prescribed time 3T/2 elapses after the start of deceleration, is defined as a target speed curve l2 to set the acceleration of the head speed. If the speed control is performed by this system, the acceleration for switching from speed control to position control is reduced to an about half of that in a conventional system. The system is provided with a magnetoelectric element 5 which detects the change of a magnetic field accompanied with the rotation of a disk-shaped scale 4 which is magnetized with N and S poles alternately on the outer periphery and is attached to the rotates shaft 3 of a spindle motor 2 integrally, a speed detecting means 6, a target speed setting means 7, and a rotation control means 9 which sets and controls the speed of the rotary shaft 3 of the spindle motor 2 based on the comparison output outputted from a speed comparing means 8 which compares the target speed and the rotative speed with each other to detect the difference.

Abstract: PURPOSE:To stably produce a microcapsule incorporating diazonium salt in which a solvent is not substantially contained by dispersing the liquid wherein diazonium salt and high molecular substance are dissolved in a nonaqueous solvent into a hydrophilic colloid soln. and raising the temp. of the soln. CONSTITUTION:In the production of a microcapsule of thermal development type copying material, both diazonium salt and a compd. which produces high molecular substance such as polyurethance by reaction are dissolved in a nonaqueous solvent such as halogenohydroearbon having b.p. of 40-95 deg.C at ordinary pressure and fatty acid ester. When this soln. is dispersed and emulsi fied in a hydrophilic colloid soln., and thereafter this system is raised in temp., wall forming substance is migrated on the surfaces of oil droplets and therein high molecule formation reaction due to polyaddition and polycondensation is advanced and a wall film is formed. By such a way, a microcapsule incorpo rating diazonium salt wherein the solvent is not substantially contained is stably produced.

IPC: H01S5/00
Filed: 1985-04-26
Abstract: PURPOSE:To obtain a shape synchronized type semiconductor laser array with good reproducibility, by forming a plurality of grooves, through which light from a light emitting part is guided on a substrate, and melting back the protruded parts on the substrate, which isolate said grooves. CONSTITUTION:A mesa is formed on the surface of a p-type GaAs substrate 1. Then, an n-type GaAs blocking layer 2 is formed on said substrate 1. Thereafter, a plurality of ridges for forming a plurality of grooves are formed on the surface of a wafer. On the mesa, on which the ridges are formed, a p-type GaAlAs clad layer 3, a GaAlAs active layer 4, an n-type GaAs clad layer 5 and an n-type GaAs contact layer 6 are continuously grown. The width of the inner ridge between the grooves is narrow. Therefore, the height of said ridge becomes lower owing to the melt back of the ridge. Thus, the light absorption at this part is decreased, and the optical coupling between light emitting parts is carried out efficiently. As a result, the phase synchronized type laser array can be obtained with good reproducibility.
