Title: Switching power circuit
Inventor: SENBA KAZUHISA
IPC: H02M3/28
Filed: 1987-06-19
Abstract: PURPOSE:To prevent the breakage by overvoltage on the load side, by providing an oscillation stop circuit in low input power voltage. CONSTITUTION:A switching power circuit made up of a self-oscillatory flyback converter is composed of a diode 23, a capacitor 24, a Zener diode 25, transistors(Tr) 27-28, etc. and an oscillation stop circuit 29 is provided in low output voltage. When the input power voltage Vin of a power source 1 gets lower, the voltage rectified with the diode 23 from a feedback winding 8 is lowered, so that the Tr 27 is turned OFF and Tr 28 ON when it is lower than the Zener voltage of a Zener diode 25. When the Tr 28 is turned ON, a main switching Tr 6 stops oscillation. No boosting of no-loaded output voltage Vout will thereby occur any longer in low input voltage.

Title: Faulty facility judgement in power system
Inventor: KOMATA TAKAO
IPC: H02H7/26
Filed: 1987-06-19
Abstract: PURPOSE:To judge a faulty facility automatically with high speed and high reliability, by extracting a facility to be included commonly in protection ranges of a plurality of protective relays when they function upon occurrence of fault and judging that facility to be faulty. CONSTITUTION:Inherent identification numbers(S2-S6) are allocated previously to facilities requiring judgement of fault, and the identification numbers of facilities included in respective protection ranges are stored in a storage device 94 for respective protective relays (C1-Cn). Upon occurrence of fault, contents stored in the storage device 94 are read out for functioned protective relays (C1-C3, for example). Then common facility numbers (e. g., S4, S5) are extracted, and judgement of faulty facility is made corresponding to the common number. Since logic for fault judgement is clarified, judgement of fault can be made automatically with high speed and high reliability.

IPC: F24H1/18
Filed: 1990-06-08
Abstract: PURPOSE:To prevent the occurrence of overboiling and to perform uniform boiling of hot water in a hot water storage tank by a method wherein boiling is effected bit by bit at temperature approximately equal to a set value as a hot water temperature is detected with time intervals. CONSTITUTION:When a set temperature H is set to 99 deg.C being a boiling temperature, a hot water temperature in a hot water storage tank 1 attains a detecting temperature H1=97 deg.C, an electric heater is turned OFF. When a given time T1 elapses, a current hot water temperature h1 is detected, and the electric heater 5 is turned ON. When a given time T2 elapses, the electric heater 5 is turned OFF, and a current hot water temperature h2 is detected again. The detecting hot water temperature h1 is compared with a hot water temperature h2, in the case of h2<=h1, a hot water temperature is not increased during a time T2 in which the electric heater 5 is turned ON, namely, it is decided that hot water in the hot water storage tank 1 is uniformly boiled. When a hot water temperature is decreased to a value lower than a lower limit temperature H2, for example, 95 deg.C, due to the use of hot water in the hot water storage tank 1, temperature control described above is repeated again.

Filed: 1986-06-30
Abstract: PURPOSE:To extract a character signal by a succeeding digital processing by providing a threshold deciding circuit and a character signal deciding circuit or the like so as to sample the video signal of character broadcast at one sampling block. CONSTITUTION:A character broadcast video signal 100 is sampled at an A/D converter 1 by using a 4fsc clock and processed digitally. Then an output signal 102B is given to the threshold decision circuit 3 via a gate circuit 2 and an output signal 102A is given to the character signal decision circuit 9. Then the signal 102B inputted to the circuit 3 is subjected to the decision of threshold level 104 to synchronize the sampling data and the character signal via the comaprator 4 or the like. Further, the signal 102A inputted to the circuit 9 is inputted to a parallel/serial (P/S) conversion circuit 7 via adders 11a, 11b or the like and outputted to a comaprator 8 as a serial data from the circuit 7. The comaprator 8 compares the input data with the level 104, binary-codes it and outputs the result to a character signal processing section. Thus, the character signal is extracted from the sampled signal value.

Filed: 1978-12-08
Abstract: PURPOSE: To detect the dielectric strength and leakage current of the semiconductor integrated circuit with non-destructive method, by detecting the current flowing when the specific active element in the semiconductor integrated circuit operated in fine current breaks down, with the current versus voltage charactristics detector.  
     CONSTITUTION: DC voltage V cc  is fed from the DC voltage source 4 between the terminals 2, 3 of the semiconductor integrated circuit 1. When this voltage increases and it is more than the dielectric strength of the input transistor Tr1 as the specific active element of the integrated circuit 1, since Tr1 breaks down, current flows to Tr1, and the current versus voltage characteristics of the curve tracer 8 is changed to the break down characteristics of Tr1. The voltage V cc  in this case is detected with the DC voltmeter 5. The voltage V cc  at break down of Tr1 and the true dielectric strength of Tr1 are in correlativity relation, and the dielectric strength of Tr1 can directly be detected as the voltage V cc .
