Title: Power supply unit
Inventor: SUGIYAMA MASAHIRO
IPC: H02M7/48
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a power supply unit which can reduce a harmonic component, without increasing switching losses. SOLUTION: If the voltage of a charging capacitor C4 is higher than that of a full-wave rectifying circuit 11, electric power is supplied to an inverted circuit 12 from a first capacitor C1 to light a fluorescent lamp at a high frequency. If the output voltage of the full-wave rectifying circuit 11 is lower than the voltage of the charging capacitor C4, electric current is supplied to a transformer Tr2 and a second capacitor C2 from the changing capacitor C4, to reduce a harmonic component. To prevent the switching loss of a transistor Q1 from increasing, a field effect transistor Q2 is turned on, while the charging capacitor C4 is being discharged without sufficiently increasing the capacity of the second capacitor C2, and a resistor R2 is parallel-connected to the first capacitor C1. Electric current is supplied to an inverted circuit 12 through the resistor R2 to restrain the harmonic component, even of the capacitor of the second capacitor C2 is not sufficient.

Title: Fuel cell power source system
Inventor: KAWASAKI TETSUO
IPC: H01M8/04
Filed: 1986-08-13
Abstract: PURPOSE:To prevent the overdischarge and overcharge of a secondary battery by installing a fuel cell current detector, in which a measured signal is outputted according to output current, and a controller, in which a setting signal and the measured signal are inputted and a control signal is outputted and the output current of a fuel cell is feedbackcontrolled by a power converter. CONSTITUTION:When a secondary battery 3 is discharged and the quantity of electricity Q of the battery is decreased, a setting signal 12a and output voltage V2 are increased to retard decrease in the Q, or adequate charge current flows to the battery 3 to recover the Q. When output current If of a fuel cell 1 is increased than a value corresponding to the signal 12, a controller 14 outputs a control signal 14a to decrease the voltage V2 and the current If to the value corresponding to the signal 12 and the overdischarge of the battery 3 can be prevented. When the battery 3 is charged and the quantity of electricity Q is increased, the setting signal 12a and the output voltage V2 are decreased to retard increase in the Q or charge current of the battery 3 to recover the Q to an adequate value. Therefore, the overcharge of the battery can be prevented. Even when the load 4 is increased, the overdischarge of the battery and sharp voltage drop in the load 4 can be prevented.

Title: Semiconductor device and motor driver circuit using same
Inventor: HATTORI MASAYUKI
IPC: H01L21/336
Filed: 1993-07-30
Abstract: PURPOSE:To prevent On of a parasitic bipolar transistor between a drain and a source by bringing a source electrode of a field-effect transistor only from a source region and providing a high concentration base region. CONSTITUTION:Since a field-effect transistor has a source electrode 9 in contact with a source region 6 and a high concentration base region 4, it scarcely operates a parasitic bipolar transistor formed of the region 6, a base region 5 and a well base region. However, when the current density is increased and an applied voltage between a drain and a source is raised, the bipolar transistor is turned ON. Accordingly, when the electrode 9 is not brought into contact with the region 5, a parasitic diode between the drain and the source can be eliminated. However, since the bipolar transistor is easily turned ON, ON of the bipolar transistor can be prevented by providing the region 4 in the region 5.

Abstract: PURPOSE:To compensate the shift of orthogonal properties and the distortion of a phase shifter and a reception signal and to improve the reliability of signal quality, by connecting a multi-value discriminator and a logical circuit to a phase detector and using the output of said detector to control a phase shifter for orthogonal reference carrier wave. CONSTITUTION:The output signals of quadruple discriminators 13 and 14 are controlled by a logical circuit 15 and added by an adder 15-4 to be applied to an LPF16. The LPF16 converts the output signal into a control signal of a DC level and applies it to a variable phase shifter 17. The shifter 17 flows the control signal to a varactor to maintain the correct orthogonal properties of the reference carrier wave applied to the discriminators 13 and 14 with control of output phase value in 90 deg. to the reference carrier wave C. Therefore, X1 and Y1 bits are demodulated in correct orthogonal properties to obtain digital signals DATA-1 and DATA-2 at the output sides of discriminators 13 and 14.
