    摘要: A receiver includes a light-receiving portion which receives an infrared remote control signal from a transmitter, an A/D converter which converts a signal received by the light-receiving portion into a digital signal at a frequency much higher than a carrier wave, and a digital filter having the band-pass function of a pass band containing the carrier band of the infrared remote control signal for the digital signal output from the A/D converter. The digital filter reduces the influence of variations in argon spectrum intensity over time.

    摘要: A power supply apparatus has a rectifier for outputting a non-smoothed DC. A switching circuit alternately shut off output of the rectifier at a high frequency, which includes first and second switches. A first capacitor couples to the first and second switches for smoothing output of the rectifier. A series resonance circuit includes a second capacitor and an inductor so that the voltage across the first capacitor becomes lower by the resonance voltage than that of the output of the rectifier. The switches are coupled to a feedback circuit including a saturatable current transformer having a primary winding and secondary winding. A control means varies the saturation time of the saturatable current transformer.
