Abstract: A power converter having a transformer with a primary side winding and a secondary side winding, each having a switch. When the primary master switch is switched on, the transformer charges. When it is switched off, the intrinsic capacitance of the secondary slave switch discharges generating the zero voltage switching condition for the secondary slave switch. The secondary slave switch is switched on at a time determined in accordance with the waveform generated by the transformer. When the secondary slave switch is switched on, the transformer discharges and ultimately the charge from an output capacitor flows into the transformer as a backflow which charges the transformer. The secondary slave switch is switched off at a time determined in accordance with a current flowing through said secondary switch. The intrinsic capacitance of primary master switch discharges generating the zero voltage switching condition for primary master switch which is then switched on.

Abstract: Antenna elements 20 are arranged at intervals “d” greater than &lgr;/2, e.g., 5&lgr;. A signal received by an antenna element 20 is sent by way of an antenna multiplexer 21 to a receiver 23, where the signal is demodulated. The thus-demodulated signal is sent to a phase-and-power detection section 25, where a phase and power of the signal are detected. On the basis of the result of such detection, a control section 26 calculates the phase and power of a transmission signal. On the basis of the result of the calculation, a transmission signal generation circuit 27 transmits a transmission signal to each of the antenna elements 20 by way of the antenna multiplexer 21.

Abstract: A variable inductor with a saturable core having three legs, including a center leg and two outer legs. A control winding is wound on the center leg and two outer windings are connected in parallel and wound on the outer legs. The inductances of the windings on the outer legs vary with the current through the control winding. The current through the control winding varies the saturation level of the outer legs. In one embodiment, the inductance of the control winding is substantially constant with a change in current in the control winding. In another embodiment, the outer legs are saturated and the center leg is not saturated. Portions of the core connecting the three legs are tapered down from the cross-section of the center leg to the cross-sections of the outer legs. The invention further includes methods of varying the inductance of an inductive circuit element in accordance with a control current.

Abstract: There is provided a D-type flip-flop circuit which is improved in terms of operating frequency. First and second current supplying circuits are provided as sources for supplying currents to first and third differential circuits for inputting data and to second and fourth differential circuits for holding data in a master circuit and a slave circuit. Further, timing for supplying the currents to the respective differential circuits for inputting and holding data are controlled by first and second clock signals, respectively. The D-type flip-flop circuit is improved in terms of operating frequency by optimizing timing for writing input data and timing for holding data by arranging the first clock signal so as to have a certain delay with respect to the second clock signal. Further, the D-type flip-flop circuit is improved with respect to the operating frequency also by optimizing the value of the currents supplied to the respective differential circuits.
