Title: Grinding method
Inventor: WATABE YOSHIHARU
IPC: B24B19/12
Filed: 1988-07-01
Abstract: PURPOSE:To make it possible to perform spark-out grinding without being affected by vibration originated in a motor to reduce chatter generation to improve the degree of machining accuracy by de-energizing the motor at the time of spark-out operation. CONSTITUTION:At the time of spark-out grinding or the final process of grinding, a switch circuit 4 is switched off by command from a controller 5 to de- energize a motor 2 for rotting a grinding wheel or a grinder, and a work W is spark-out machined by inertial rotation of the grinding wheel 1. Since the motor 2 is thus de-energized, vibration originated in the motor 2 does not occur and the generation of chatter due to the vibration can be positively prevented. As a result, the degree of accuracy of machining and grinding the work W can be improved.

Filed: 1981-10-14
Abstract: PURPOSE:To enable to obtain the prescribed precision of a laminated magnetic iron plate by one time punching by a method wherein before the punching processing of the magnetic iron plate, slit type punching processing is performed at the notch part corresponding position. CONSTITUTION:By the first time punching, a punching iron plate 100 of the first sheet is punched, and a slit 100S is punched at the punching position of the second sheet separated by L from the notch part 100C. Then the second punching iron plate 200 is punched, while a slit 200S is punched at the position of the third iron plate. At the time when the second punching iron plate 200 is to be punched, residual stress is in released condition owing to the previously punched slit 100S. Accordingly te prescribed precision can be obtained by only one time punching having no fear to give influence to punching precision.

IPC: B24B9/00
Filed: 1994-06-23
Abstract: PURPOSE:To easily carry out uniform chamfering by arranging a filing face in an approximately conical inner face part formed in the tip part of a bar member. CONSTITUTION:A main body part 10 is rotated while the tip part of a bar member 60 is brought into contact with sandpaper 20 fitted to a conical inner face part 12, and the bar member 60 is parallelly moved around a shaft of a rotary shaft without the bar member itself being rotated while the tip part of the bar member 60 is pressed onto the inner face part 12.

Abstract: PURPOSE:To reduce parasitic capacity and to enable an ultrahigh speed operation by composing an insulating layer region buried in the surface of a semiconductor substrate under wirings and in contact with an element isolating region. CONSTITUTION:Undercut parts formed at the inner walls 29, 31 and the upper edges of element isolation grooves 29, 31 are merely selectively oxidized to form an insulating layer region 34 so made of thick SiO2 as to bury in the surface of a substrate in contact with the upper edges of the grooves 29, 31. Accordingly, the substantial thickness y1 of the insulating layer between wirings for leading a base electrode, made of a polycrystalline layer 42 and an n-type semiconductor layer 24 is increased by the layer 34 and an SiO2 layer 36a formed thereon, and a parasitic MIS capacity C2 is decreased. A tolerance size between the isolation region and a base contact region can be determined in a self-alignment by the undercut or the like thereby to reduce the capacity C2. As a result, a capacity CCB between the base and the collector can be reduced, and an ultrahigh speed bipolar transistor integrated circuit can be obtained.
