Abstract: PURPOSE:To shorten an alternate processing time by providing a 2nd magnetic head accessing the alternate sector of the alternate cylinder corresponding to a defective sector and accessing the alternate sector by the 2nd magnetic head when a 1st magnetic head accesses the defective sector. CONSTITUTION:When the sector 1a in the track 1 to be accessed is found to be a defective sector, the access is switched from the head 4 to the access of a magnetic head 7 at the time when the magnetic head 4 accesses this sector 1a, the head 7 accesses the alternate sector 3a of the track 3 of an alternate cylinder and the information thereof is read.

Abstract: PURPOSE:To improve the efficiency of degaussing of an electromagnetic chuck and the like by a method wherein the voltage of the 1st capacitor, provided to a differential amplifier, is gradually reduced by FF and the charging speed of the 2nd capacitor, charged by FF, is gradually increased by comparing the 2nd capacitor voltage with the 1st capacitor voltage and the source whose plus and minus amplitude is alternately reduced gradually is used. CONSTITUTION:When a switch 10 is ON, an output (c) of a NOR circuit 11 becomes H through FFs 7, 8 and a thyristor T9 becomes conductive and a DC source is applied to a chuck 3 to magnetize it. When a switch 9 is ON for a certain period, an output Q of FF15 becomes H and an output Q' of FF17 becomes L and a coil 26 is excited and contacts K1, K2 are changed. The voltage of a capacitor C3 is reduced gradually and a capacitor C4 begins being charged. When an output of a differential amplifier is produced, a one-shot multiplexer 24 is triggered to discharge the capacitor C4 and the coil 26 is not excited and the contacts K1, K2 are changed. By repeating above procedure, the degaussing voltage is reduced gradually.

Title: Resin mold bonded with decorative film and its manufacture
Inventor: ARAKAWA YUKIYASU
IPC: B32B15/08
Filed: 1988-03-03
Abstract: PURPOSE:To make it possible to represent an elaborate pattern, by bonding and inserting a metallic layer into a transparent hole with pressure, aligning the upper surface of said metallic layer to be even with the upper surface of a printing ink layer and forming a very small gap between the inner surface of said transparent hole and the lateral surface of said metallic layer. CONSTITUTION:When a resin 11 is injected to within a cavity 2 of metal mold, the resin 11 and a base film layer 8 of a decorative film 3 are integrally welded because of the pressure of the injection molding. Simultaneously, each layer from a coating layer 5 to the base film layer 8 is, upon receipt of the injection molding pressure of the resin, bent towards a transparent hole 9 of a printing ink layer 4. As a result, a metal layer 7 coated with the coating layer 5 is pressed to inside the transparent hole 9. However, since the metal layer 7 is not allowed to bend at right angles to a lower edge 12 of the transparent hole 9 due to the bending resistance thereof, a very small gap delta is formed between the inner surface of the transparent hole 9 and the coating layer 5. The very small gap delta acts a so-called hemming effect. Accordingly, a resin mold 13 appears to have a thin black hem line 15 around a character section 14, thereby realizing stereoscopic feature.

IPC: C23C2/38
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of heat for holding the temp. of a plating bath and to reduce the cost by preheating a steel tube cut into a standard dimensional length to a specified temp,. thereafter dipping it into a plating bath at a specified temp. and time, next taking it up from the bath and controlling the coating weight of the plating on the outer face of the steel tube. SOLUTION: This steel tube is preheated to 100 to 600 deg.C before its dipping into a plating bath. The plating bath temp. is regulated to 430 to 480 deg.C in consideration of the fluidity of zinc and the facilitation of the control of the coating weight of the plating. Furthermore, the time for dipping the steel tube into the plating bath and executing plating is regulated to 20 to 100 sec. In this way, as a zinc-iron alloy layer formed on the surface of the steel tube, an alloy layer mainly composed of δ1 phases is formed by a suitable amt., and the adhesion of a galvanizing layer formed on its upper layer is enhanced to prevent the cracking and peeling of the plating layer at the time of subjecting the plated steel tube to bending.  Moreover, the plating can be executed in such a manner that the dipping time in the bath is regulated to a short time to increase the productivity.
