摘要： A high-voltage variable resistor capable of significantly reducing a circuit board as compared with a prior art. Terminal fitments each are arranged so as to function as a connector for forming electrical connection between a slide element slid on each of variable resistance patterns and a terminal acting as an output section. A contact point between a contact on a contact support of the terminal fitment and a plate-like member of the slide element is positioned apart from a surface of the circuit board. The terminal fitment includes a positioner, which is positioned outside the pattern in a radial direction thereof, so that the positioner intersects the pattern while being spaced therefrom.

摘要： A lead wire connection terminal fitment capable of permitting a plurality of lead wires to be readily press-fitted in a single lead wire press fit groove. The terminal fitment may be in the form of a relay terminal fitment, which includes a metal plate formed with a lead wire press fit groove by machining in which lead wires are press-fitted. A pair of inner surfaces of the metal plate defining the lead wire press fit groove therebetween are formed thereon with a plurality of projections and recesses engaged with an outer periphery of lead wires. The projections biting into the lead wires are so arranged that a space defined between the projections opposite to each other is reduced in width at a position thereof spaced by a distance in a depth direction of the lead wire press fit groove, resulting in being divided into a first space portion increased in width and a second space portion decreased in width.

摘要： A reverse bias voltage is applied to a photodiode array provided with a plurality of avalanche photodiodes operated in Geiger mode and with quenching resistors connected in series to the respective avalanche photodiodes. Electric current is measured with change of the reverse bias voltage applied, and the reverse bias voltage at an inflection point in change of electric current measured is determined as a reference voltage. A voltage obtained by adding a predetermined value to the determined reference voltage is determined as a recommended operating voltage.

The bias control means has a diode having the same temperature dependence of a breakdown voltage as that of the avalanche photodiode, and a control circuit for applying positive and negative potentials with respect to the ground potential between the anode and the cathode of the diode such that the diode is set in a breakdown state at a predetermined current. A positive or negative potential is applied from one of the anode and the cathode of the avalanche photodiode as a bias voltage, and a photocurrent is output from the other terminal of the avalanche photodiode.
