Title: Diagnostic system and method of evaluating performance of valve in steam turbine-system
Inventor: SAAJI PIITAA BAATON
IPC: F01B/
Filed: 1991-01-25
Abstract: PURPOSE: To diagnose the performance of a valve component by including a means of comparing the position of a shaft with a prescribed position, comparing the angular position changing rate of a shaft for discriminating fluctuations according to the characteristics of a check valve, and providing a status report indicating the working condition of the check valve through a computer means. CONSTITUTION: A valve 10 is disposed between an isolation valve 94 and a feed water heater 96. The isolation valve 94 and a check valve 10 are placed at an extraction steam pipe 98 where a steam turbine 99 is connected to the feed water heater 96. During the ordinary operation of a turbine, the isolation valve 94 and the check valve 10 are in the full-open condition, thereby permitting extracted steam to flow into the feed water heater 96. The first sensor senses the rotational position of the shaft of the check valve 10 and the second sensor senses the prescribed condition of the isolation valve 94 for outputting signals.  Computers 66/68 compares a shaft position with a prescribed one, discriminates fluctuations of the check valve 10 by comparing the changing rate, and indicates the status report of the check valve 10, thus it is possible to diagnose the performance of valve components.

Title: Vibration-analyzing apparatus
Inventor: TADA TAKESHI
IPC: G01M11/00
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To separately measure only the deformation of optical parts and a housing due to vibration by separating a vibration system, a measurement system and a light projection system in structure. SOLUTION: In a state in which an optical write unit 1 is not vibrating, the angle of a reflecting mirror 6 is adjusted to make a light reciprocate on the same optical path. A spot position of a position sensor 8 at this time is set as a reference position. Light projected from a light source 7 passes through a beam splitter 9, is reflected by a mirror 5 of a vibration-insulating structure arranged in front of a rotating polygon mirror 2 as a vibration system, is reflected by the reflecting mirror 6 arranged at an image form position of the unit 1, returns in the original course, is reflected by the beam splitter 9 and received by the position sensor 8. At this time, an optical part of the unit 1 is deformed upon the receipt of vibration, thereby minutely changing the optical path which is observed as a shift of the spot position on the sensor 8.  Optical influence due to the vibration can be measured by calculating the positional change (positional shift) of the optical spot at the stationary time and vibration time.

Title: Driving device of write head onto magnetic card
Inventor: KAWASAKI KAZUNORI
IPC: G11B5/09
Filed: 1983-02-17
Abstract: PURPOSE:To simplify remarkably a circuit for driving a transistor (TR) bridge circuit by making a device to have the constitution that a bias current of a PNP TR is supplied from a collector of an NPN TR of complementary TRs placed oppositely. CONSTITUTION:Suppose at first that a TRQ1 is switched ''ON'' by a signal S1 and a TRQ2 is switched ''OFF'' by a signal S2, then a bias current is applied from a bias current supply circuit RB2 to a TRQ3, thereby causing the TRQ3 to be switched ''ON''. On the other hand, since the TRQ2 is switched ''OFF'' and the TRQ3 is switched ''ON'', no bias current flows to a TRQ4, causing the TRQ4 to be switched ''OFF''. That is to say that it is possible to flow a current to a write magnetic head HD in both directions and to interrupt the current therefrom by changing the switch condition of the TRs Q1, Q2 by the signals S1, S2.

Title: Gate turn-off thyristor
Inventor: SAKAMOTO HIROAKI
IPC: H01L29/74
Filed: 1988-02-08
Abstract: PURPOSE:To uniformalize a forward voltage drop value and a gate current value and thereby to increase a controllable current tolerance, by depositing an N<+> layer on the fringe of a semiconductor substrate deeper in an NB layer or in larger than the one deposited on the center of the substrate. CONSTITUTION:A semiconductor substrate 1 is four-layer structured (PE-NB-PB- NE layers), with the NE layer split into some islands. Several N<+> layers are deposited in the PE layer so as to reach the NB layer, so the NB layer contacts an anode electrode 2 via these N<+> layers (Anode short structure). On each of the NE layer split into some lots, a cathode electrode 3 is formed, while a gate electrode 4 is formed on each portion of the PB layer which is deposited a little deeper than the NE layer. By this, stronger anode short effects can be gained on the fringe of the substrate than on the center of it. As a result, a forward voltage drop value and a gate current value of each of the cathode emitter NE layers can be uniformized and thereby, a controllable current tolerance can be increased.

Abstract: PROBLEM TO BE SOLVED: To make accurate picture recognizing processing executable even on such electronic parts that are one-sidedly stuck to a suction nozzle by vacuum and do not come within the range of a recognition camera. SOLUTION: When a suction nozzle 12 reaches a picture recognizing position, the position of a recognition camera 14 is corrected so that the whole body of electronic parts 13 may come within the range of the camera 14 only when it is discriminated that the parts 14 are partially positioned on the outside of the range of the camera 14 based on the comparison between picture data taken with the camera 14 and the preset attribute data of the parts 13. After the position of the camera 14 is corrected, the amount of the positional deviation of the parts 13 from the nozzle 12 is calculated by again performing recognizing processing based on the picture data taken by means of the camera 14 after correction.

Filed: 1978-03-08
Abstract: PURPOSE:To ensure a highly efficient use of the exclusive line with no especial addition of the D/A converter but by always setting the channel to part of the time division channel. CONSTITUTION:Both A station and C station are used as the space division type exchanges, and station C is the time division type exchange. And the time division transmission line connects between stations A and B as well as between B and C respectively.
