Title: Thin film magnetic head
Inventor: YAMAZAKI SHIYUUSUKE
IPC: G11B5/31
Filed: 1982-11-25
Abstract: PURPOSE:To prevent the damage on the surface of a magnetic substrate on account of overetching by laminating respectively a protective layer of Ti, a conductive layer of Cu, etc. and a mask layer of Ti on a magnetic substrate. CONSTITUTION:A Ti film 9 to serve as a protective layer is deposited by evaporation at about 1,000-1,500Angstrom  on a magnetic substrate 1 and further a Cu film 7 to serve as a lead is deposited by evaporation at about 2mu thereon; further, a Ti film 8 to serve as a mask is deposited by evaporation at about 1,000-1,500Angstrom thereon. A photoresist pattern is formed on a wafer and the film 8 is worked by a dry etching method. The film 7 is sputter-etched with the film 8 as a mask. Overetching is performed to etch off thoroughly the film 7 in this stage but the rate of the sputter etching for Ti is about 1/10 of the rate for Cu, therefore even if the overetching is performed, the surface of the substrate 1 is protected by the film 9 without removing the film 9 and the surface of said substrate is entirely smooth.

Title: Method for measuring electrostatic capacity of cable run to ground
Inventor: MATSUNO TATSUJI
IPC: G01R27/16
Filed: 1987-08-20
Abstract: PURPOSE:To measure accurate ground electrostatic capacity by compensating variation of the phase characteristics of a ground electrostatic capacity measuring circuit with simple circuit constitution. CONSTITUTION:A measuring low-frequency signal voltage of frequency f1 different from the commercial power source frequency is inputted to a cable 2 through the ground line LE of transformer T. A leak current component of frequency f1 fed back to the ground line LE and a voltage which is almost in phase with the low-frequency signal voltage are detected synchronously by a 1st synchronous detector MULT1 to obtain a 1st output. A voltage which deviates from the nearly in-phase voltage by a slight fixed phase quantity and a leak current component of frequency f1 are detected synchronously by a 2nd synchronous detector MULT2 to obtain a 2nd output. The ground electrostatic capacity of the cable is measured from the difference between the 1st and 2nd outputs. Consequently, the accurate ground electrostatic capacity is measured.

IPC: G06F3/033
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To easily and exactly detect and hold the timing of arbitrary and plural interrupting requests.
