Title: Method for measuring fundamental wave power and higher harmonic power of strain wave power supply
Inventor: HORII TATSUO
IPC: G01R23/20
Filed: 1991-01-24
Abstract: PURPOSE:To measure fundamental wave power and higher harmonic power by measuring the effective values of voltage and a current by an effective value indication type meter and storing the waveforms of both of them in a waveform memory apparatus and measuring average power by a voltmeter. CONSTITUTION:The effective values of voltage and a current are measured and the waveforms of both are simultaneously stored and average power is measured by a voltmeter. Next, the stored waveforms are subjected to FFT analysis to respectively determine the ratios of respective higher harmonics to a fundamental wave. By taking the sum of the values obtained by squaring the respective ratios from the order corresponding to the fundamental wave to the order of higher harmonics to be considered, the ratio of the effective value of a strain wave to the effective value of the fundamental wave is calculated and the fundamental wave effective values of line voltage and a phase current are determined. From the stored waveforms, the phase difference of the voltage and current of the fundamental wave is calculated. The phase difference of the fundamental waves of phase voltage and line voltage is 30 (150) deg. because both of a power supply and load are in an equilibrium state. By correcting this phase difference, fundamental wave power is calculated. Next, higher harmonic power is calculated by subtracting the calculated fundamental wave power from the average power of a wattmeter.

IPC: F24D17/00
Filed: 1984-04-27
Abstract: PURPOSE:To fill a hot-water supplying pipe with hot-water having a temperature higher than a predetermined temperature at all times in order to effect tap-controlled hot-water supplying by a method wherein a control valve is opened to discharge low-temperature hot-water when the temperature of hot-water is reduced while the same valve is closed when the temperature of the hot-water is increased. CONSTITUTION:When a switch is thrown in, the control valve 18 is opened, a flow amount detector 16 detects the flow amount of hot-water and a hot-water and water mixing valve 15 is driven to obtain a temperature set in a setting unit 20. When the switch of the setting unit 20 is put OFF, the control valve 18 is closed and the supply of hot-water is stopped. Simultaneously, the detector 16 detects the stop of supply of hot-water and the operation of the hot-water and water mixing valve 15 is stopped. When the temperature of hot water around a hot-water temperature thermistor 17 is reduced to a value lower than the set value due to natural heat dissipation under a condition that the supply of hot-water is being stopped, the control valve 18 is opened forcibly, the cooled hot-water in the hot-water supplying pipe 13 is discharged and the hot-water supplying pipe 13 is filled with high-temperature hot-water coming from a hot- water supplier heat source equipment 12 while the control valve 18 is closed when the temperature of hot-water around the thermistor 17 is increased to a value higher than the set value.

Abstract: PURPOSE:To stabilize blast furnace operation by measuring the position and distribution of the fusion zone in a blast furnace in the blast furnace operation and controlling fuel ratio, blast conditions and charge distribution in such a manner that the fusion zone attains a prescribed pattern. CONSTITUTION:The temps. at least at 3 points of the fusion zone, i.e., top layer part, intermediate part and root part are measured by flexible probes inserted through a rigid lance 3 embedded into the blast furnace 1 in order to detect the distribution of the fusion zone in the blast furnace.

Title: Broad-band reversed-l-shaped antenna
Inventor: MISHIMA AKIRA
IPC: H01Q13/08
Filed: 1979-07-11
Abstract: PURPOSE:To widen the frequency band of synthetic input impedance with a passive element roughly coupled, by adding a compensating element to a reversed-L-shaped antenna and then by varying the input impedance of the reversed-L-shaped antenna. CONSTITUTION:Electric current, once fed from input terminal 1, is shunted to radiating element 2 and parallel element 4 to radiate an electromagnetic wave into the air, but part of the electromagnetic wave propagates to passive element 6 to generate electric current on element 6 in proportion to the extent of coupling, so that part of it will be radiated again. When the extent of coupling between the reversed-L-shaped antenna and passive element 6 increases up to >= one tenth, rough coupling should be applied since an influence on directivity increases and, in consequence, mutual interference lessens, so that the frequency band of input impedance can not be widened. For the purpose, compensating element 7 with distribution constants of fine inductance L and fine capacity C is added to vary the input impedance of the reversed-L-shaped antenna, thereby widening the frequency band of the synthetic input impedance.

Abstract: PURPOSE:To simplify a program and to improve processing speed by providing a chip with an intellectualized hardware function. CONSTITUTION:Two DC motors (main driving M1, optical system scanner M2) are driven by intellectualized I/O ports PWM1, PWM2 in a microcontroller MCU1. There are two registers for counting up a pulse PI1 generated from the FG1 of the main driving motor M1 to control the whole sequence and for measuring the pulse interval to execute servo control. A pulse PI2 is also a pulse input from an FG2 for detecting the speed and position of an optical system scanner motor and its position and speed are detected by two registers similarly. The counted value of an encoder pulse controlled at its timing is inputted to the PI1 of the microcontroller MCU1. Consequently, a servo controller in a motor control system is processed by an I/O port register in the microcontroller.

Abstract: PURPOSE:To eliminate an offset voltage at a circuit output by bringing the level of the back gate of a transistor(TR) switch for capacitor changeover provided between an inverting input terminal of an operational amplifier and a capacitive element or a switched capacitor to the level of a noninverting input terminal of the operational amplifier.

Moreover, when the switches S1, S2 are realized by using P-channel MOS TRs, since the TRs are turned on and off, then the overlap capacitance of the gate being the parasitic capacitance caused in the process does not give effect on the offset voltage of the output VOUT of the circuit also.

Title: Method of detecting overload of motor
Inventor: OGINO SEIICHI
IPC: G01L3/00
Filed: 1994-03-31
Abstract: PURPOSE:To detect constant overload at all times without depending upon the magnitude of applied voltage in the detection of the overload of a motor. CONSTITUTION:A period tn is measured from pulses continuously generated with the revolution of a motor (ST1), and the next period tn+1 is measured when the next pulses are generated. A cycle is continued while the period tn+1 is used as a new one tn when the period tn+1 is smaller than a discrimination value consisting of the sum of the period tn and a value obtained by multiplying the square of the period tn by a constant B, and load is discriminated as overload and the motor is stopped when the period tn+1 is larger than the discrimination value (ST2-ST5). The constant B is acquired by multiplying each constant determined by the used motor by a coefficient correcting a delay by a mechanical time constant. Accordingly, overload can be discriminated by formula using the period without being converted into the number of revolution, thus simplifying processing, then allowing discrimination without being subject to the effect of voltage fluctuation.
