Title: Rice bran removing cylinder of transverse type rice grinding and polishing apparatus in rice polisher and manufacture of rice bran removing cylinder
Inventor: ASAKURA KUNIKATSU
IPC: B02B3/06
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To make a rice bran removing cylinder easy to manufacture and provide efficient rice bran removing performance by using a martensite type stainless steel sheet for making a rice bran removing cylinder in which a rice polishing roll is to be housed and which is installed continuously to the outlet side end of a horizontally transporting roll chamber and forming a large number of rice bran removing long holes in the cylinder by laser processing. SOLUTION: In a rice polisher, a large number of rice bran removing holes 31, 32 are formed in a rice bran removing cylinder 30 and rice bran on the surface of unpolished rice is scraped and dropped when the unpolished rice passes through respective rice bran removing holes 31, 32 following the rotation of a rice polishing roll 40. In this case, a martensite type stainless steel sheet is employed as a material for the rice bran removing cylinder 30 and a large number of rice bran removing long holes 31, 32 are formed by radiating laser beam from the side of the stainless steel sheet to be the surface side of the rice bran removing cylinder 30. Consequently, martensite having remarkably high hardness is formed in the surrounding of the rice bran removing long holes 31, 32 due to the heat generated at the time of cutting process by laser beam.  Moreover, at the same time, flange-like parts are formed in the back sides of the rice bran removing holes 31, 32 and the rice bran removing holes are sharpened.

Title: Manufacture of electric oscillation circuit
Inventor: FURITSUTSU PIHIRU
IPC: H01L27/01
Filed: 1991-08-16
Abstract: PURPOSE: To prevent new activities from occurring attended with malfunctioning due to breakdown, without exposing Al yarns by introducing many fibrous moldings and at least enough buried in a dielectric so as to cause the conductive coupling between two faces of a capacitor. CONSTITUTION: For the spark discharge between faces of capacitors at both sides of a dielectric, many moldings having a size of a micron range, e.g. Cu dusts are introduced and buried fibrously in a dielectric 1 so as to cause the conductive coupling. This introducing of the moldings includes selecting zones overlapped with the capacitor faces in a support film and blowing the moldings on the dielectric 1 by heating, having, pressuring or pushing them by rollers. This perfectly eliminates the malfunction and makes Al yarns produced during inactivating never break due to the electric insulation breakdown but protect in the dielectric and buried.

Title: Magnetic disk device
Inventor: AKAMATSU NAOTOSHI
IPC: G11B25/04
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To decrease polymerizable gaseous components of the inside, to suppress the formation of deposits by the reaction at a head-disk boundary and to prevent the magnetic disk fault by the deposits by providing the above device with a mechanism which polymerizes the gaseous component having polymerizability by a catalyst, etc., converting these components to material having a small vapor pressure and adsorbing and fixing the material. SOLUTION: The cause for the magnetic disk device fault by the trace gaseous components lies in that the gaseous components give rise to a polymerization reaction between the magnetic head 3 and the magnetic disk 2 and that the polymerized matter thereof turns to the deposit and accelerates wear. Then the expulsion of the material having the polymerizability is necessary. The mechanism for progressing the polymerization reaction at a temperature as low as possible is required for this purpose and the use of the ionic catalyst having an acidic active point or basic active point on the surface is recommended. As one example, a porous crystalline body consisting essentially of SiO-Al2O3 molded to a planar form is installed as the catalyst 1 in part of a disk housing part.  As a result, the amounts of the head deposits decrease drastically as compared with the case the catalyst 1 is not installed.

Title: Reproducing time managing device
Inventor: YASUDA TAKEHIKO
IPC: G11B20/12
Filed: 1994-08-31
Abstract: PURPOSE: To attain the reducing of the burden of a system controlling microcomputer by counting the number of sound groups in an encoded signal decoding part. CONSTITUTION: An encoded signal decoding part 4 checks data transmitted from a buffer memory control part 3 and checks whether a sound group to which the data belong is the starting of a music or not. When the group is the starting of the music, a procession SG is defined as '0'. When the group is not the starting, whether a CUE/REV mark is present or not in the data is checked. When the mark is present, the number of procession SGs is added by the number of jumpted SGs. When the marke is not present, the decoding part receives the data of one SG from the control part 3 and executes an expanding procession to them to output audio data to output terminals. Next, the number of the procession SGs is increased by 1. A reproducing time is calculated by multiplying the number of procession SGs by the time of one SG.  Then, whether the reproducing procession is completed or not is checked and in the case the reproducing is not completed, whether the starting marke is present or not is repeated again. Thus, the burden of the system controlling microcomputer is reduced by performing in such a manner in the encoded signal decoding part 4.
