Title: Protection method for transformer
Inventor: UCHIYAMA TOMOYUKI
IPC: H01F29/02
Filed: 1995-06-08
Abstract: PURPOSE: To detect the inner fault of a phase regulation transformer reliably by deciding whether a fault is present in the phase regulation transformer based on the current flowing through a regulating winding to be connected in parallel with a power system and the phase of a current flowing through a tap winding. CONSTITUTION: A series transformer 3 has a series winding 31a to be connected in series with a transmission line and a voltage is fed from an exciting winding 32a to the series winding 31a. The series winding 31a and the exciting winding 32a are wound around a core. On the other hand, a regulation transformer 4 has a regulation winding 41a to be connected in parallel with a power system and a predetermined voltage is fed from a tap winding 42a to the exciting winding 32a of series transformer 3. A stabilizing winding 43a, the regulation winding 41a and the tap winding 42a are wound around the core. A decision is made whether a fault is present in the regulation transformer 4 based on the phase difference between currents flowing through the regulation winding 41a and the tap winding 42a. Consequently, the inner fault of regulation transformer 4 can be detected reliably.

Inventor: SUDOU MASATOSHI
IPC: C21D9/48
Filed: 1979-10-31
Abstract: PURPOSE:To impart excellent press formability comparable to that obtained by batch annealing, by performing simultaneous quenching and strain developing of cold rolled steel sheet having been recrystallization-annealed with a water-cooled roll, then by overaging the steel sheet while cooling slowly. CONSTITUTION:Cold-rolled steel sheet is heated rapidly from room temp. T0 to a temp. T1 which is not lower than the recrystallization temp. so as to perform recrystallization-annealing. The recrystallized steel sheet is quenched at 50-500 deg.C/sec cooling rate C2 by passing it between plural water-cooled rolls, at the same time 0.2-3% strain is imparted to the steel sheet. That is, the oversaturation of solid soln. carbon is increased at the step, and dislocation is introduced by strain, and the overaging time is reduced by the quick decrease in carbide and solid soln. carbon which precipitates during overaging process. Then the steel sheet having been imparted with strain is slowly cooled continuously or stepwise so as to overage it. The slow-cooling rate from the starting temp. T5 of overaging to the final temp. T6 (250-400 deg.C) of the overaging is set at 10-100 deg.C/min, and the overaging may be completed in about 2-8min.

Abstract: PROBLEM TO BE SOLVED: To make measurable the shape of particles by making minute particles travel in an AC magnetic field, detecting a magnetic field change as electromotive force from the travel of the particles, and finding the relationship between the posture and the electromotive force by changing the posture of the particle with respect to the magnetic field.

Title: Communication processing system

IPC: H04L1/00
Filed: 1992-05-07
Abstract: PURPOSE:To improve the reliability by checking a header, a sequence number and an error check value in received data at a reception station so as to discriminate the validity of the received data and making a retransmission request to a transmission station when the data are not valid. CONSTITUTION:A transmission station A sends transmission data 1a with a header 21a, a sequence number 22a, and an error check value 23a as redundant information added to them. A reception station B discriminates the validity of the received data by checking the header 21a, the sequence number 22a, and the error check value 23a and sends an affirmative reply or a re- transmission request to the transmission station A. Thus, the transmission station A makes transmission of succeeding data or re-transmission of preceding data on a request of the reception station B. When an error takes place in the data received by the reception station B and the lapse of the occurrence of the error takes place in the opposite direction to the flow of events, the reception station B makes processing of defective reception and gives an affirmative reply to the transmission station A to allow the station A to send succeeding data.

Title: Image pickup device
Inventor: OKINO TADASHI
IPC: H04N5/238
Filed: 1983-08-03
Abstract: PURPOSE:To enable precise and quick exposure control by controlling exposure condition of an image pickup device by using output of the image pickup device or output of a sub-photometric circuit continuous in time sequence. CONSTITUTION:After lapse of sufficient time after a power source switch is turned on, a diaphragm 2 is stabilized at a proper value. Accordingly, the result of photometry by a subphotometric circuit 8 does not deviate largely from proper range and output of a window comparator 9 becomes high level. Under this condition, a diaphragm driving circuit 13 controls the diaphragm 2 at high accuracy and in long time constant basing on luminance information from an image pickup element 5. On the other hand. In the case of sudden change of luminance of the subject, the diaphragm can not follow up quickly. Accordingly, output of the circuit 8 becomes a value largely deviated from the proper range, and output of the comparator 9 becomes low level. Then, the circuit 13 controls the diaphragm 2 in real timing basing on information of the circuit 8.

Filed: 1986-06-17
Abstract: PURPOSE:To increase the speed of response of the control of an optical output, to remove the difference of optical outputs on a continuous output and on pulse modulation while lowering loss in a control system and to reduce power consumption by detecting the peak value of laser output beams and comparing the peak value with a reference signal. CONSTITUTION:A gate is opened only when there is an output from a laser diode 1 in a gate circuit 3, and the gate circuit 3 is synchronized with a pulse modulation circuit 9, thus operating the gate circuit 3 so as to prevent the leakage of a peak-output detection circuit 4. The peak output detection circuit 4 detects the peak value of laser output beams 11 from the laser diode 1 and transmits it over a comparator 5, compares it with the reference voltage Vs of a reference supply 6, and controls a current control circuit 7 by a control signal 13 on the basis of the comparison. Accordingly, speed detection-responding to the fluctuation of a laser output is increased, the difference of optical outputs on a continuous output and on pulse modulation is removed while the loss of a control system is lowered, and power consumption can be reduced.

IPC: C12N1/16
Filed: 1987-06-09
Abstract: PURPOSE:To prepare an alcoholic drink, etc., rich in caproic acid and/or ethyl caproate, by using a cerulenin-resistant mutant yeast produced by proliferating a yeast variant in a cerulenin-containing medium. CONSTITUTION:Various kinds of yeast are mutated by physical process (e.g., ultraviolet irradiation) or chemical process (suspension in a solution of a mutagenic agent such as ethylmethane sulfonate) and the variant is transferred to a cerulenin-containing medium and cultured at about 30 deg.C. The grown yeast strain is separated and a strain having high activity to produce caproic acid is selected from the strain. The obtained cerulenin-resistant strain has increased productivity of medium fatty acid including caproic acid compared with the parent strain. Since any variant yeast derived from SAKE yeast, SHOCHU yeast, beer yeast, wine yeast and bakers' yeast is imparted with high productivity of caproic acid, a SAKE (refined Japanese rice wine) produced by the use of the yeast is rich in ethyl caproate having an apple-like flavor.

Abstract: PROBLEM TO BE SOLVED: To simplify attachment of a double-sided tape to a heat radiation plate and application of an adhesive and manufacture an inexpensive thermal head, by making a flat even face a face of the heat radiation plate to which a heat-generating resistor substrate and a flexible circuit board are secured, and bending the flexible circuit board when fixing the board to the heat radiation plate. SOLUTION: A face of a heat radiation plate 5 to which a heat-generating resistor substrate 1 and a flexible circuit board 4 are attached is made an even face without a step. The substrate 1 and board 4 are attached to areas of the face having a breadth conforming to an attachment breadth.
