Abstract: PURPOSE:To provide a DC current sensor having a relatively simple structure and a detection capacity with excellent linearity over a wide range of current from a micro current to a relatively high current (e.g. 0.2-20A). CONSTITUTION:In the structure where an exciting coil 13 and a detection coil 14 are toroidally wound around an annular core 11 made of a soft magnetic material, the direction of flux in the core 11 is reversed when the exciting coil 13 is fed with a triangular exciting current for generating a magnetic field stronger than the coersive force of the core 11. The timing of reversion is detected based on a pulse voltage induced in the detection coil 14 and the absolute value of DC current flowing through a lead wire to be detected is detected, along with the direction thereof, by comparing the pulse intervals.

Title: Manufacture of continuity contact terminal
Inventor: HITOMI YASUYUKI
IPC: G01R31/28
Filed: 1992-09-25
Abstract: PURPOSE:To provide a method for manufacturing an inexpensive contact terminal, allowing an electrical connection properly corresponding to a high-density and fine pattern such as in a liquid crystal display panel. CONSTITUTION:In this method for manufacturing a continuity contact terminal, many conductive members 3 of spring quality having micro breadth are fixed to an insulation member 2 at micro intervals, while the ends of the members 3 are projected from one end of the insulation member 2 by the predetermined length. The members 3, after subjected to an etching process for having the predetermined size and arrangement, are bonded and fixed to the insulation member 2. Thereafter, both ends of the members 3 are cut off. Many conductive members 3 can be thereby arranged accurately at micro intervals. Also, the warp or strain thereof is small after the process, and a continuity contact terminal can be manufactured at extremely low cost as small as 1/10 of the conventional method. The use of the same material for a tested substrate and the insulation member of the contact terminal results in the same thermal expansion coefficient. Thus, a proper electrical connection can be ensured without any dislocation of a pitch in measurements, tests or the like involving a temperature change. According to this construction, a continuity contact terminal capable of coping with a micro pattern having a pitch as small as 0.1 mm can be manufactured.

Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce the strain and initial deformation of a spacer and also to equalize the clamping force of a disk in the circumferential direction of the disk. SOLUTION: A notch groove of a prescribed size is formed on the surface of a spacer that is set opposite to a disk, and the spacer separates each pair of adjacent disks from each other among plural sheets of disks.
