Filed: 1986-06-19
Abstract: PURPOSE:To measure with reliability by utilizing the charge to be charged electrostatically by electrostatic induction to a metal plate placed at a definite distance from a high voltage part and constituting to sense the high voltage. CONSTITUTION:The metal plate 1 is placed at the definite distance from the high voltage part 4, a propeller-shaped metal body 2 is rotated by a motor 3 near in front of the metal plate 1 and the metal body 2 is short-circuited electrically by earth 8. Then the motor 3 rotate the metal body 2 at a constant speed and covers the metal plate 1 periodically two times per one rotation, and a voltage waveform takes a saw-tooth-wave having two fold frequency due to the charge of the metal plate 1. This signal wave is amplified by a high impedance amplifier 5 to be inputted to a comparator 6 and compared with a constant threshold voltage Et at the comparator 6 to be outputted as a square-wave of a constant amplitude. And measuring a duty ratio by means of a duty ratio measurement instrument 7, high voltage is thereby sensed. The reliable measurement is thus executed.

IPC: H02H3/28
Filed: 1995-06-12
Abstract: PURPOSE: To prevent an erroneous control by quickly detecting the failure in reception data by a differential current protection relay device based on CPU processing. CONSTITUTION: A ready signal S3a which is turned on or off at each sampling period is inserted from a transmission part 7a to transmission data and is fed to a differential current protection relay device 4b at one's party terminal when a device normally operates at a ready signal creating part 7a. Transmission data from one's party edge which are similarly treated are compared with the ready signal of a previous sampling by an own terminal reception part 8a and are outputted as a ready normal signal S8a after confirming that they change from ON to OFF or from OFF to ON. When a transmission line 1 fails, a relay operation output S6a of a differential current relay operation part 9a is outputted and a command S9a is outputted by performing AND operation with the ready normal signal S8a.

Title: Field effect transistor
Inventor: YANO NORIYUKI
IPC: H01L29/812
Filed: 1984-07-11
Abstract: PURPOSE:To remarkably improve a gate delay time by providing a buried layer having a conductivity type opposed to that of the operation layer to a semi-insulated substrate provided between a high concentration layer and operation layer. CONSTITUTION:A high concentration layer 4 consisting of the n<+> layer having a high carrier concentration in the same conductivity type as the operation layer 2 is formed by ion implantation with a gate electrode 3 used as the mask. The p type buried layer 5 having the conductivity type opposed to that of the operation layer 2 is also formed by the ion implantation. Since the p type buried layer 5 is embedded at the lower end part of the source and drain of operation layer 2, sufficiently small amount of electrons are implanted to a semi-insulated substrate 1 from the high concentration layer 4 and therefore short channel effect is difficult to occur. Therefore, a threshold voltage is not lowered even when the gate length is made shorter than the existing one. As a result, a mutual conductance can be set large and a gate delay time can also be shortened.

Filed: 1989-06-09
Abstract: PURPOSE:To reduce a noise factor by a method wherein wiring metal films for coupling a gate metal film with gate pads are respectively coupled with the gate metal film through 3 pieces or more of contact windows and the contact windows are linearly coupled with the gate pads by the wiring metal films. CONSTITUTION:A gate metal film 4 is connected with gate pads 7 by wiring metal films 9 through contact windows 8 and the pads 7 are connected with gate terminals of a package by the wiring metal films. As these windows 8 are linearly coupled with the wiring metal films 9 and are coupled with the gate metal film 4 in a fan form, the gate metal film 4 is connected with the pads 7 at short distances and a resistance and a phase difference between the windows and each power feeding point become very small. Therefore, the loss can be lessened, the noise factor is significantly improved and the gain is also augmented. For example, in a 12-GHz band, the noise factor can be reduced from 1.0dB to 0.5dB and the gain can be augmented to 10dB to 12dB.

Title: Liquid discharging head, liquid discharging unit and recording method
Inventor: ISHINAGA HIROYUKI
IPC: B41J2/05
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of unevenness in a recording image at a gap of a plurality of isolation walls or a gap of a plurality of boards by making a discharging characteristic distribution uniform in a liquid discharging head having a plurality of boards and(or) a plurality of isolation walls. SOLUTION: A gap 35 is generated between a board 1a and a board 1b. Foaming pressure might be sometimes released via the gap 35. Thus, a shape of movable member 31b is formed so as to enhance a discharging efficiency to more sufficiently receive the foaming pressure corresponding to heaters 2 at ends of the boards 1a and 1b. Specifically, its size is increased more than that of the other movable member 31a. Thus, discharging characteristics of respective nozzles are made uniform, and hence no irregularity that a recorded image become pale in density does not occur on this part due to reduction in discharging amount caused by a decrease in an efficiency only at the ends of the boards 1a and 1b. The member 31b may be dealt with other parameter which can alter discharge characteristics such as position of a fulcrum or a free end in addition to size.
