IPC: C22C45/02
Filed: 1990-08-31
Abstract: PURPOSE:To produce an Fe-base soft-magnetic alloy excellent in high frequency magnetic properties, etc., and reduced in magnetostriction by temporarily applying rapid solidification to a molten metal of the undermentioned alloy, subjecting the resulting amorphous alloy to heat treatment, and regulating the structure so that fine crystalline grains of specific grain size comprise the greater part of the structure at the time of producing an Fe-base soft-magnetic alloy with a specific composition. CONSTITUTION:A ribbon-shaped amorphous alloy of about 5-100mu thickness is formed by means of rapid solidification by chill block melt spinning from a molten metal having a composition (atomic%) represented by a general formula, where M means Co and/or Ni, M' means one element selected from Nb, W, Ta, Zr, Hf, Ti, and Mo, 0<=a<=0.5, 0.1<=x<=30, 0<=y<=30, 0<=z<=25, 5<=y+x<=30, and 0.1<=alpha<=30. This amorphous ribbon is worked into the prescribed shape by means of coiling, punching, etching, etc., and heat-treated in vacuum or in an inert gas atmosphere at 450-700 deg.C for 5min-24 hr, by which a structure in which fine crystalline grains of <=1000Angstrom  average grain size comprise at least 50% is formed. By this method, the Fe-base soft-magnetic alloy reduced in core loss and also reduced in the change in core loss with the lapse of time can be obtained.

Title: Hooded cutter link and grinding method
Inventor: MAIKERU BUI PETOROBUITSUCHI
IPC: B24B3/40
Filed: 1988-09-16
Abstract: PURPOSE: To obtain an optimum cutting efficiency by taking a large hook angle, and reducing a rake angle, thereby suppressing a reaction force to an allowable range. CONSTITUTION: A top plate angle is changed, and a reduce allowable side plate angle of 25 degrees is formed. Accordingly, an influence of an ellipse affecting to a hook angle HA is reduced. A position of a top 34 of a file 12 to a cutting edge 28 is lowered to set the angle HA to 30 degrees. The angle HA is obtained by drawing a line at one point of a side plate cutting edge 26 disposed down from a cutting end. Thus, a predetermined top plate cutter edge angle of about 25 degrees is obtained, and a lowering angle is set to 0 degree. When the angle HA is increased in the degree of allowing against a reaction force to provide a rake angle for allowing the top plate, an optimum cutter can be manufactured.

IPC: H02M3/28
Filed: 1988-09-19
Abstract: PURPOSE:To perform a stable constant-voltage operation over a wide range of AC input voltage by changing the maximum attainable value of a switching pulse duty ratio in a switching pulse duty ratio control circuit using a low voltage and a small current in such manner that the number of turns of a demagnetization winding is changed by a power converter part.

Title: Method for regulating air-core coil
Inventor: UCHIDA MASAMI
IPC: H01F21/02
Filed: 1985-10-18
Abstract: PURPOSE:To enable inductance of air-core coils to be regulated without changing their coupling state even in case of regulating M-coupled air-core coils, by keeping an earth-connected metal plate away from and near to the air-core coils. CONSTITUTION:Inductance of air-core coils 2 (or 3) can be changed by moving a metal plate 1 in the arrow-indicated direction, so that a coupling state between these air-core coils 2 and 3 may not be changed. Because the inductance of the M-coupled air-core coils can be changed in this way without changing a coupling state in which the air-core coils are coupled to each other, the regulation method becomes simpler and easier than that for the previous regulation one. Besides, even one air-core coil becomes superior in its appearance.

Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To narrow the pitch of fuses according to the increase in the degree of integration of a semiconductor device by arranging zigzag laser light casting regions used when cutting a fuse which are provided in a plurality of fuses respectively. SOLUTION: On a base substrate 50, a block layer 52 for suppressing laser ablation is formed.

Abstract: PURPOSE:To expand the freedom of solder selection by fixing a light emitting element and an optical fiber opposed to the light emitting element respectively on a carrier forming a through hole with solder. CONSTITUTION:The light emitting element 1 is joined through solder 2a on the carrier 3 joined with a package 4 through solder 2b, solder 2c is mounted on the surface of the carrier 3 and heated and melted so that an optical fiber 5 is embedded in the solder 2c, and then the fiber 5 is positioned and fixed so that optical coupling efficiency for the light emitting element 1 is improved.
