    摘要： When a front fog lamp and a rear fog lamp are turned on by swinging an operating knob 4, a holder 18 climbs up to the crest portion 13b of a cam 13 and brings the tip of an engaging piece 22 into contact with the edge face of a coupling member 41. When an operating knob 5 is swung from an OFF position to an AUTO position in this state, the engaging piece 22 is urged by a coil spring 21 to resiliently stick into an arcuate engaging hole 45. When the operating knob 5 is swung back to the OFF position, an operating knob 4 is swung back by the engaging piece 22 in an interlocking mode. Then the holder 18 climbs down from the crest 13b of the cam 13 and causes the rear fog lamp to be turned off and only the front fog lamp is held ON.

    摘要： A switching power supply which detects a power failure within a short period and maintains the DC output voltage (V.sub.O) for a long time. The switching power supply comprises a first voltage control means which controls a switching means (2) by means of a pulse width modulation means (9) which responds to a first voltage comparator means (8) which compares the DC output voltage (V.sub.O) and a reference voltage (V.sub.R); a second voltage control means having a pulse width modulation means working voltage range expansion means (12) which responds to a second voltage comparator means (11) which compares the DC output voltage (V.sub.O) and a second reference voltage (V.sub.RR); wherein further provision is made of a second switching means (16) for connecting a precharged second capacitor (15) in parallel to the first capacitor (1), in response to the second signal successively outputted by the second voltage comparator means (11) in a short period.

    摘要： A switching regulator for controlling an output voltage by a pulse width of a switching element such as a transistor and the like at a primary side of the switching regulator. The switching regulator is provided with a feedback element which converts an output voltage at a secondary side into a feedback current, and controls an amount of charge of a capacitor (C3) to control a time for which the transistor (Q1) is kept on at the primary side and an amount of charge of a speed-up capacitor (C2) at the primary side. When a small load is imposed, an excessive increase in the output voltage can be prevented by controlling an amount of charge on the capacitor (3) to control the keeping-on-time and an amount of charge of the speed-up capacitor (C2) at the primary side. This also shortens the time for which the transistor (Q1) at the primary side is kept on.

    摘要： A ringing converter of the type having an output voltage stabilizing circuit connected on the primary side of a transformer. The converter is further provided with a circuit for detecting the primary current, which is proportional to the load current on the secondary side of the transformer. This enables detection of a change in the output voltage due to fluctuation in the load current on the secondary side, as detected by the detecting circuit. A signal indicative of the detected change is fed back to an oscillator circuit in order to stabilize the output voltage.

    摘要： A stabilizing power supply apparatus including, as a switching element, a magnetic amplifier supplied with a rectangular wave voltage produced by an inverter and controlled by a reset current. An error sensing circuit senses a difference between the output voltage of the magnetic amplifier and a reference voltage to produce an error signal corresponding to the sensed difference. An amplifier circuit amplifies the error signal into the reset current for the magnetic amplifier. The amplifier circuit includes a NPN-type transistor for amplifying the control current into the reset current and first and second diodes. The first diode has an anode terminal connected to a negative power supply line and a cathode terminal connected to the collector of the transistor in order that charge will not accumulate on the transistor base. The second diode has an anode terminal connected to the emitter of the transistor and a cathode terminal connected to the magnetic amplifier. The reset current is applied to the magnetic amplifier through the second diode to hold the output voltage of the apparatus constant by regulating the on/off timing of the magnetic amplifier in accordance with the difference between the magnitude of the output voltage and the magnitude of the reference voltage.
