Title: High-speed separation and restoration system of trouble of distribution line
Inventor: FUJIKI TOSHISADA
IPC: H02H7/26
Filed: 1988-07-27
Abstract: PURPOSE:To improve the reliability of the supply of a distribution system largely by combining and using a current circulation type pilot wire relay deciding a trouble section at high speed and static type switches installed at each sectional point. CONSTITUTION:When the trouble of a short circuit or a ground fault is generated at the point F of a section 102, current circulation type pilot-wire protective relays 63, 64 respond by the exchange of a current input through a pilot 602, a static type switch 711 is opened by the operation of the pilot-wire protective relay 63, and an opening command is emitted to a static type switch 712 by the working of the pilot-wire protective relay 64. Since the pilot-wire protective relays 63, 64 respond, on the other hand, a closing command is transmitted to a loop-point static type switch 700 through an information transmission line not shown. Accordingly, after trouble is generated, the static type switches 711, 712 at both ends of a trouble corresponding section respond at high speed while the loop static type switch 700 treated in normally opening is closed, thus restoring the voltage sections 101, 103 except the trouble section at approximately the same time as trouble is eliminated.

Inventor: OGURI KATSUHIKO
IPC: G11B5/31
Filed: 1995-06-29
Abstract: PURPOSE: To obtain a low-impedance-noise thin-film magnetic head. CONSTITUTION: The thin-film head is constituted by laminating an insulating film 2, magnetic cores 3, 9, and 12, and a coil 7 on a substrate 1 in order. The coil 7 is formed etching the insulating film 2 to form a coil groove 7a and then embedding a conductor film in the coil groove; and the thin-film head has a stopper film 18 for groove depth control at the coil groove etching, and the formation range of the stopper film 18 on a lower core 4 is limited to the area sandwiched almost between the upper and lower cores 4 and 12, thereby overetching the insulating film by a specific quantity at the coil groove etching. Consequently, the coil groove depth in an area where the stopper film is not present is made deeper than the coil groove depth of the area where the stopper film 18 is present to lower impedance noise.

Title: Microsequence control system
Inventor: HOSAKA KAZUHIDE
IPC: G06F9/22
Filed: 1988-07-29
Abstract: PURPOSE:To omit a microbranch deciding register, etc., and to perform the microbranch operation at high speed by designating the bit position and the bit width into a microinstruction and producing an optional mask bit pattern. CONSTITUTION:A right shifter 2 produces '1' in number equal to the number of bits designated D by the bit width of an internal register of a microinstruction register 1. These '1' are shifted to the right by a right register 3 in number equal to the number of bits designated C by the bit position of the internal register. Thus a mask bit pattern is obtained. The right shift operation is also applied to a bit pattern designated E by a bit pattern by a right register 4. This pattern is compared with the data on an internal bus 10 for each bit by a comparator 5. A coincidence detecting circuit 6 detects the coincidence between said bit pattern and a non-masks pattern of a mask bit pattern. Then the propriety of the microbranch is set at a flip-flop 8.
