Title: Ground protection relay device for synchronizer
Inventor: FUJIMOTO MUTSUZOU
IPC: H02H7/06
Filed: 1995-06-09
Abstract: PURPOSE: To detect grounding even in a condition that it is not incorporated in parallel in the system, without malfunctioning even at operation with rather weak excitation. CONSTITUTION: In a first setting means 7, an operation range is set, on the basis of the correlative relation between the field current of a synchronizer and the third harmonics contained in the zero-phase voltage at the neutral point, and in the second setting means 8, an operation range is set, on the basis of the correlative relation between the revolution of the synchronizer and the third harmonics. A switching means 10 selects the operation range of the first setting means 7, when the synchronizer is incorporated in parallel in the system, and it selects the operation range of the second setting means 8 when the synchronizer is switched off from the system. And, a detection means 11 detects the neutral point grounding when the detected third harmonics get in the operation range selected by the switching means.

IPC: H01F7/20
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To provide an electronic controller capable of normally processing the voltage signal generated based on the potentials of different ground lines. SOLUTION: This controller has a diode 40 which conducts and limits the control ground potential VGc when the potential (drive ground potential) VGd of a drive ground line Gd which grounds a drive part 10 that drives the load L is lower than the potential VGc of a control ground line Gc which grounds a control part 20 that controls the part 10 by 0.5 V or more. The part 20 includes the level shift circuits 32 and 34 which shift a pair of voltage signals VH and VL showing the potentials at both ends of a current detection resistance 14 placed at the part 10 by an extent equivalent to the shift voltage (1.5 V) and supply the shifted voltage signals to an operational amplifier circuit 22. Thus, the input of the circuit 22 is always higher than the potential VGc and the circuit 22 can always operate in a normal state.

Title: Two-dimensional fourier transformation device
Inventor: YOROZU JUNICHI
IPC: G06F17/16
Filed: 1988-07-07
Abstract: PURPOSE:To always perform the 2-dimensional Fourier transformation with the optimum efficiency by using a single data train transformation part, a plural-data train parallel transformation part, and transformation method selection part which selects the optimum one of two said transformation parts based on the size of the input data. CONSTITUTION:A single data train transformation part 3 performs the Fourier transformation via the vector arithmetic to the vector element produced by taking an element out of the single 1-dimensional data. While a plural-data train parallel transformation part 4 performs the Fourier transformation via the parallel vector arithmetic to the vector elements produced by taking the data having the same element number out of plural data having the same length. In addition, a conversion method selection part 2 selects the part 3 or 4 in accordance with the length of each dimension of the input data so that the optimum processing efficiency is secured for the vector arithmetic. In such a constitution, it is possible to prevent the deterioration of the arithmetic speed of a vector processor and to ensure the optimum Fourier transformation despite the large difference produced among the data lengths in each dimensional direction.

Title: Apparatus for decontamination of pool water
Inventor: HASEGAWA JIYOU
IPC: C02F1/32
Filed: 1979-12-26
Abstract: PURPOSE: To effectively remive COD components from pool water and to remarkably reduce a required amount of supplemental fresh water, by radiating ultraviolet rays to the pool water in the presence of an injected chlorine agent.  
     CONSTITUTION: Water withdrawn from a pool 1 is carried to a strainer 4, where bulky solid in separated from the water, and to a filter 5 by a pump P, where solid suspensions are separated. The water is then carried to an ultraviolet radiation device 6, where COD components are separated from the water by the ultraviolet radiation, while a chlorine agent is charged from an injector 7 so as to keep a residual chloride content in the water at a predetermined level. The treated water is returned to the pool 1. In case where the residual chlorine content in the water out of the filter 5 is too low, the chlorine agent is charged from the injector 7 into the water to be carried in the ultraviolet radiation device 6. Consequently, the ability of ultraviolet rays for removing COD components is improved several times in the presence of chlorine.

Title: Power source
Inventor: NAKANO KATSUAKI
IPC: H02M3/28
Filed: 1982-09-29
Abstract: PURPOSE:To prevent a power transistor from breaking at a trigger signal applying time by clamping the control voltage of a voltage controlled oscillator by a voltage corresponding to the control voltage at the lower or supply limit of the output voltage controlling range. CONSTITUTION:When an output voltage or current increases, the control voltage from an error amplifier 13 decreases, and the oscillating frequency from the voltage controlled oscillator 1 rises. Thus, the ON and OFF frequency of a power transistor 5 increases, and the output voltage or current is maintained constant. When a trigger signal is applied in the state that an input power is applied, the minimum value of the control voltage is clamped substantially at the initial voltage determined by a Zener diode 20. In this manner, the oscillating frequency of the oscillator 1 is prevented from abnormally rising after the trigger signal is applied.

Title: Operation bending degree setting type bending conductive element

IPC: G01B7/16
Filed: 1987-07-08
Abstract: PURPOSE:To obtain a bending conductive element which accurately detect variation in electric resistance value due to bending deformation by providing a bending control member for setting the operation bending area of the element within a specific range. CONSTITUTION:The deforming conductive sheet 3 which has electrodes 4 fitted on both ends is stuck on a lead spring 2 and bending control members 1 are fitted to both ends of the leaf spring 2. Then one end of the member 1 is fixed to one end 2a of the leaf spring 2, and a stopper 1c is provided to the other end of the member 1 and engaged loosely with the other end of the leaf spring 2. The end 2b is therefore freely movable in the bending direction of the leaf spring 2 from a position prescribed by the stopper 1c. Consequently, an electric resistance measuring instrument connected to the electrodes detects a decrease in the resistance of the bending conductive element which bends more than the initially set degree of bending and when no stress is applied, the element returns to the initially set degree of bending by the member 1.
