Title: Method and device for effecting magnetic polishing of inner surface of container
Inventor: SUZUMURA TAKEO
IPC: B24B31/112
Filed: 1992-05-28
Abstract: PURPOSE:To improve polishing efficiency through cutting off of the protrusions and recesses of the inner surface of a container by a method wherein mixture magnetic grinding grains prepared by mixing together fine magnetic grinding grains and large iron powder larger than the magnetic grinding grains is charged in a position, situated facing a magnetic pole, in the container. CONSTITUTION:Mixture magnetic grains charged in a container W are formed of mixture of magnetic grinding grains J and iron powder F larger than the magnetic grinding grains. The iron powder F is aligned and intercoupled in a chain-form manner along the direction of a line of magnetic force. Fine magnetic grinding grains J are adhered to the periphery thereof to produce a firm magnetic force holding module (polymer). The magnetic force holding module is deformed in a form where a part of the mixture magnetic grinding grains J are slipped down over a slope owing to rotation of the container W. The direction of a firm line of magnetic force is kept approximately in a constant state and a polishing pressure is continued to exert a polishing pressure on the inner surface of the container W. The polishing pressure causes cutting off of the protrusions and the recesses of the inner surface of the container W to improve polishing efficiency.

Abstract: PURPOSE:To constitute a cylindrical magnet easily even when it has a large size, and to prevent flux concentration easily by using the cylindrical magnet by charging a thin cylindrical pipe with a permanent magnet block. CONSTITUTION:A rectangular parallelopiped unit magnet having the same shape is used as permanent magnets 5a, 5b in contents in a thin cylindrical pipe 1, and the permanent magnets 5a, 5b are charged vertically symmetrically, holding a soft iron block 4a. Unit magnets 5c of another kind are inserted into the clearances of these unit magnets, and soft iron blocks 4b-4d are charged into residual clearance sections. Consequently, the corner sections of the unit magnets are inscribed directly with the pipe 1 and the apices of the soft iron blocks 4a, 4d are inscribed with the pipe 1 in the contents of the pipe 1, the contents of the pipe 1 are unified and fixed to the pipe 1, thus acquiring an integral permanent magnet. Accordingly, magnetic flux concentrates to contacts among the unit magnets and the soft iron blocks and the pipe 1 when the pipe 1 has magnetism, but it does not concentrate to one point, and the degree of the concentration of magnetic flux is further lowered when the pipe 1 has non-magnetism.

Title: Superfinishing method for raceway groove of ball bearing
Inventor: KOSAKA KATSUTOSHI
IPC: B24B19/06
Filed: 1985-07-19
Abstract: PURPOSE:To have efficient processing by performing lapping by the use of a tape coated with abrasive grains consisting of boron nitride of cubic crystal type, thereby providing uniform striation due to processing in a raceway groove and lessening the frequency of tape replacement. CONSTITUTION:The foremost surface 5 of a tape pressing member 3 is given the same curvature as that of a raceway ring 1, and a lapping tape 10 consisting of a base tape 11 coated one one of the sides with abrasive grains 13' of cubic crystalline boron nitride (CBN) with the aid of adhesives 12, is pressed to the raceway groove 2 in the raceway ring 1. Then the tape 10 is run in the longitudinal direction (as shown by arrow), and the above-mentioned tape pressing member 3 is swung oscillatively in the direction along the curvature, and now processing is performed with the raceway ring 1 revolved at a high speed. These abrasive grains 13' which are harder than diamond cause less crush and eventual crush should produces a flat and smooth plane of cleavage, so that uniform and continuous striations 4' are left on the raceway groove 2, and thus noise generation is less when a ball bearing is formed. Sharpness in cutting should require less frequency of tape 10 replacement to accomplish effective processing.

Title: Automatic voltage regulator for ac generator
Inventor: OKABE SADAKATSU
IPC: H02P9/30
Filed: 1981-10-08
Abstract: PURPOSE:To prevent the burning of a field coil by restraining a field current at the time of low-speed rotation and of high-speed rotation. CONSTITUTION:Since the outputs of a voltage detecting unit 3 and a frequency counting unit 4 are small at the time of low-speed rotation, the reverse rotation output of a comparator 5 is added to an output of a reference voltage unit 8, and a comparator 7 gives a signal of normal rotation to a thyristor phase control circuit 9 to restrain a field current. When the speed of rotation reaches that of the rotation of medium - high speed, the output of the voltage detecting unit 3 turns large, thereby the output of the comparator 7 is inverted, and the field current increases. When the speed of rotation reaches high - maximum speed, the output of the voltage detecting unit 3 is saturated and the output of the comparator 5 is turned normal. Therefore, the comparator 7 is put against in the state of normal rotation, and thereby the field current is restrained. By this constitution, the burning of a field coil and the damage of a semiconductor can be prevented.
