    摘要： Disclosed is a power resistor which has a large heat capacity per unit volume and an appropriate and stable electrical resistance, and in which the resistance changes little with time due to surge absorption. This power resistor includes a sintered body containing aluminum oxide and carbon, and a pair of electrodes formed on the two opposing surfaces of the sintered body. This sintered body consists of first regions containing a small amount of carbon or not containing carbon and second regions containing a larger amount of carbon than in the first regions and so arranged as to be connected to the electrodes.

    摘要： A light source power supply circuit includes a DC power source and an energy accumulating capacitor connected in parallel through a charging switching element to the DC power source. A polarity inverting circuit is connected across the energy accumulating capacitor for applying the capacitor voltage across a light source with the polarity alternately inverted. A starting high voltage generating circuit applies a high voltage to the light source a high voltage for starting the light source. A control circuit controls a polarity inverting circuit so that the inverting frequency is above a critical fusion frequency for the light source.
