Filed: 1995-05-11
Abstract: PURPOSE: To obtain the smooth torque having small pulsation of the torque of a motor by driving the motor based on the output signal of a phase waveform converter for converting a plurality of phases having different phases to the waveforms of an AC current and outputting the output signal. CONSTITUTION: Trapezoidal waveform data, for example, is stored in a data storage unit 8. The waveform data read from the unit 8 is used to match the rotation of a motor 5, converted to a plurality of phases of AC waveforms having different phases by a phase waveform converter 9, and the AC current based on the converted AC waveform is supplied to the motor 5. Then, the torque of the motor 5 is increased at the time of the maximum torque generated by the currents of the phases, the time from when the maximum torque of the one phase starts to be decreased to when the torque generated by the current of the other phase becomes maximum is shortened, and the pulsation of the generated torque is decreased. Thus, the torque of the motor 5 can be smoothened.

Title: Light-activated thyristor and photo-coupling type semiconductor relay
Inventor: YAMADA KOICHI
IPC: H01L31/111
Filed: 1994-05-26
Abstract: PURPOSE:To improve photosensitivity by completely avoiding lock-on phenomenon. CONSTITUTION:A resistor R1 and a MOSFET 1 are connected in parallel between a second gate C2 and a cathode terminal K of a thyristor SCR. The gate of the MOSFET 1 is connected to the cathode terminal K and a first gate G1 of the thyristor SCR via diodes D1 and D2, respectively. A phototransistor PT is connected between the first gate G. of the thyristor SCR and the cathode terminal K, thus enabling light excitation current flowing to the phototransistor PT where light is applied to contribute as the gate current of the first gate G1 of the thyristor SCR and improving the photosensitivity of the light-activated thyristor PTh. Also, since the resistance between the second gate G2 and the cathode terminal K of the thyristor SCR is not large, the generation of heat by the thyristor SCR can be reduced, thus preventing lock-on phenomenon from being generated.

Title: Fuel filtering unit with automatic drain
Inventor: KONDOU SEIICHI
IPC: F02M37/32
Filed: 1982-06-30
Abstract: PURPOSE:To prevent a coil from being heated by providing a thermistor with positive characteristics on a drain solenoid valve control circuit between the solenoid valve of a fuel filtering unit with an automatic drain and the power supply, and reducing an electric current immediately after opening said drain solenoid valve to a degree that the opened condition of the valve can be maintained. CONSTITUTION:If the level of the separated water rises and detecting electrodes 34, 35 are immersed in it, potential difference arises across a resister R1, a transistor Tr1 is made conductive, and the resultant current ignites a thyristor TH. Then, an electric current flows through a thermistor 53 with positive characteristics located between the power supply 52 and a drain solenoid valve 4, opening the valve. Since the thermistor is heated and the value of its resistance is increased when an electric current flows through it, the flow of a current to an exciting coil 45 is reduced, after a short time, due to the resistance of the thermistor, maintaining less flow of a current than that when the operation is started, while the draining is continued. Thereby, the coil can be prevented from being heated, and its size can be reduced.

Filed: 1990-04-26
Abstract: PURPOSE:To warrant the stable operation of a repeater by constituting an AGC circuit based on a signal always superimposed on a main signal having a different frequency. CONSTITUTION:When a signal from a 2nd filter 4 is smaller than a reference value, an AGC amplifier 6 increases the gain to a signal from a 1st filter 5, and conversely when the signal from the 2nd filter 4 is larger than the reference value, the AGC amplifier 6 decreases the gain. Thus, the amplitude of a monitor and control signal inputted to a supervisory and controlling circuit 7 is always made constant and the repeater is operated stably. Moreover, even when a signal from the 1st filter 5, the signal from the 2nd filter 4 is always present thereon the the gain of the amplifier 6 is not too much increased, thereby preventing a malfunction.

Abstract: PURPOSE:To improve the gain of the entire antenna at each frequency band by calculating an optical length correction through the weight mean of phase errors of a primary radiator according to a function of calculated power density and modifying a curved face of a sub reflecting mirror based on the result. CONSTITUTION:The shape of a main reflecting mirror 3 and a sub reflecting mirror 2 is decided in advance based on a condition that an optical length from a primary radiator 1 to an aperture 4 of an antenna is constant. Then a power density and a phase error of a radio wave radiating from the primary radiator 1 are calculated as to plural frequencies included in a multi-frequency band at each point on the sub reflecting mirror 2 phase errors of the primary radiator 1 at plural frequencies are subjected to weighted mean value calculation based on the calculated power density function. Thus, an optical path length correction at each point of the sub reflecting mirror 2 is calculated and a curved face of the sub reflecting mirror 2A is modified based on correction data. As a result, the gain of the Cassegrain antenna system using the multi-frequency band is improved over the entire multi-frequency band.
