Title: Automatic voltage controller for power plant
Inventor: SATO OSAMU
IPC: H02P9/14
Filed: 1992-06-08
Abstract: PURPOSE:To improve an efficiency of a power plant by so selecting a voltage change amount of a terminal of a generator and a step-up transformer switching tap as to minimize a sum of a generator loss and a step-up transformer loss for a reactive power of the generator or a secondary side voltage of the transformer. CONSTITUTION:The automatic voltage controller for a power plant comprises a transformer 11 for an instrument, a signal input circuit 14 and an operating state calculator 15, etc., as shown by a broken line in the drawing. Particularly, a loss calculator 19 calculates a loss based on a generator constant and a transformer constant previously stored at a combination of a generator voltage and a step-up transformer tap position selected by a possible operation state calculator 18, and selects a combination of a minimum loss. Further, a setter 20 outputs the generator voltage and the tap position to become minimum loss selected by the calculator 19 to a voltage setter 7 and an LTC tap position setter 21. Thus, total sum of the losses of the generator and the transformer can be minimized, and it can contribute to an improvement in an efficiency of a power plant.

Title: Semiconductor device and its manufacture
Inventor: KAJIYAMA HIDETO
IPC: H01L21/768
Filed: 1994-06-06
Abstract: PURPOSE:To expand the alignment displacement margin of a wiring pattern when the wiring pattern is formed to the upper section of a contact hole formed onto a substrate. CONSTITUTION:An inter-layer insulating film 2, and inter-layer films 12, 13 are laminated on an Si substrate 1, a contact hole 4 is formed through RIE, and a conductive material 5 is buried, thus forming a plug 6. The inter-layer film 13 is removed while leaving the inter-layer 12, thus projecting the plug 6. A wiring material 8 is deposited on the plug projecting section 14 and the inter-layer film 12, and a wiring is shaped onto the plug 6 through etching by resist patterning. A sidewall is formed even to the periphery of the projected plug at the time of the etching of wiring formation, thus preventing the intrusion of etching into a boundary between the plug 6 and the contact-hole sidewall by the sidewall even when a resist 7 at the time of wiring patterning is to some extent displaced from the contact hole 4.

Abstract: PURPOSE:To detect a phase current by a simple structure by detecting a voltage between terminals of a current detecting resistor between a detecting timing delayed by a predetermined time from ON timing of a plurality of switch elements and a detection finishing timing earlier by a predetermined time than OFF driving. CONSTITUTION:When a drive signal is externally input to a driver 21, it is passed through a limiter 29, converted into a PWM signal by a PWM circuit 30, and input to a signal generator 31. A dead time td is set to ON periods of transistors Q1, Q4 according to drive signals U, EU, the transistor Q4 is turned ON after the time td after the transistor Q1 is turned OFF by the signal U, and after the time td is elapsed, a sample and hold circuit 41 starts sampling. When the transistor Q4 is turned OFF by the signal EU, the circuit 41 finishes sampling earlier by the time td and starts holding. As a result, accurate phase current can be detected by a simple structure.

Title: Optical scramble method and optical transmission system using the same
Inventor: IIDA MASANORI
IPC: H04B10/00
Filed: 1993-06-18
Abstract: PURPOSE:To apply scrambling to an optical signal optically. CONSTITUTION:A burst light source 3 whose wavelength is close to that of a transmission light source 2 is arranged and both optical signals are scrambled in the optical signal processing way and when an optical path changeover section 6 selects an optical path 10, the original signal cannot be demodulated because the optical signal with a burst optical signal mixed therein is received by an optical receiver 8. Furthermore, when an optical path 11 is selected, a wavelength selection section 7 suppresses the burst optical signal and the original optical signal is led to the receiver 8. The optical path is selected as required to decode the scrambled optical signal.

Title: Computation method of differential voltage for ac voltage
Inventor: TAKEUCHI REIJI
IPC: G01R29/18
Filed: 1991-06-20
Abstract: PURPOSE:To enable the computation of a differential voltage of an AC voltage at a high accuracy by determining a compensation coefficient from amplitudes and a phase difference of two AC voltages measured with a breaker closed to compensate a amplitude difference and the phase difference based on a compensation formula. CONSTITUTION:When amplitudes Vgamma1 and Vgamma2 and a phase difference DELTAPHIgamma of an AC voltage measured 101 and 102 with a breaker 1 closed are computed by a differential compensation coefficient computing means 104 by a command of a differential voltage compensation coefficient computation command means 103, errors of the voltage measuring means 101 and 102 do not bring an amplitude difference DELTAVgamma and the phase difference DELTAPHIgamma to zero. Here, a required coefficient of a specified compensation type is computed 104 and stored beforehand based on the measured values and a differential voltage computing means 105 compensates computed values of a difference DELTAVR of the amplitudes DELTAVR1 and DELTAVR2 and the phase difference DELTAPHIR as when the breaker 1 is kept optional based on the compensation formula to output a compensation coefficient and the difference DELTAVRH of the amplitudes and the difference DELTAPHIR of the phases compensated. Thus, the computation of a differential voltage with limited error is made possible thereby enabling the measuring of the differential voltage of the AC voltage at a high accuracy.

Abstract: PURPOSE:To minimize the defects in production and to simplify a production process by producing UV shielding film parts by high-temp. calcination of a positive type photoresist. CONSTITUTION:The film obtd. by calcination of the positive type photoresist at 200-400 deg.C is used as the film for shielding UV rays of a photomask for shielding the UV rays in a pattern shape.

Title: Colored original reader
Inventor: SHIRAISHI MASAYOSHI
IPC: H04N1/19
Filed: 1988-06-15
Abstract: PURPOSE:To uniformize the S/N of the title reader at each color so that the S/N can be compensated automatically even when the spectral sensitivity characteristics of the reader change by reading a white reference plate immediately before reading an original and automatically setting the accumulating time of each color. CONSTITUTION:When an image sensor 2 reads a white reference plate 14 for a fixed accumulating time, an output corresponding to the state of a color separation switching means 1 at that time is obtained as the picture signal 8 of the sensor 2. The picture signal 8 becomes a white reference plate reading signal 13 through an output detecting means 4 and is inputted to a control circuit 5. The circuit 5 calculates the signal 13 and inputs a timer setting signal 11 together with a color switching signal 7 so that a prescribed accumulating time can be obtained. An accumulating time setting means 6 has three timers when color separation is to be made against three colors of R, G, and B and adds a line signal 10 which decides the accumulating time to the sensor 2 by means of the timers. The sensor 2 reads an original with an accumulating time which is different from that used for reading the reference plate 14 and the picture signal 8 is inputted to a picture signal process circuit 3, from which the picture signal 8 is finally outputted as picture data.

Abstract: PURPOSE: To perform condensation treatment of NH 3  cycle that can cope with sea water leakage by adding a simple regeneration operation to a desalting process of using a cation exchange resin layer and a mixed bed type ion exchange resin layer.  
     CONSTITUTION: The condensate of a boiler etc. is flowed into a desalting tower 1 from its upper part and at normal time it is taken out through an outflow pipe 9 from the approximate intermediate part of a mixed bed type ion exchange resin layer MB. At this time, iron oxide etc. are removed by a cation exchange resin layer CR s . In the event of sea water leakage, a valve 26 is closed and a valve 27 is opened to flow the treated water to the under layer part of the layer MB and is treated in the part where the exchange resins are held of H type right after regeneration. The regeneration is performed separately by separating both cation and anion exchange resins to prevent the reverse regeneration that occurs in the mixed state.
