摘要： Disclosed is a high-voltage pulse generating circuit comprising an inductor, a first semiconductor switch and a second semiconductor switch connected in series between both ends of a DC power supply unit. A diode unit is connected between a gate terminal of the first semiconductor switch and one end of the inductor (namely, one end of a primary coil). A resistor is connected between the gate terminal of the first semiconductor switch and the one end of the inductor. The resistor serves as a gate current-supplying means which allows a gate current to flow to the first semiconductor switch when the second semiconductor switch is turned on.

摘要： A flow path from outer gas introduction apertures 144a to inner gas introduction apertures 134a has a narrower-width flow passage formed by an inner wall member 150. This structure effectively lowers the probability that a liquid, such as water, entering from the outer gas introduction apertures 144a passes through a gas inflow chamber 122 and reaches a sensor element 110, compared with a structure without the inner wall member 150. The inner wall member 150 is formed as a solid member that is capable of storing the surrounding heat. Even if there is a certain event that has the potential of causing a temperature decrease of the sensor element 110, for example, an abrupt change in flow rate of an object gas, the heat stored in the inner wall member 150 effectively prevents a temperature decrease of the sensor element 110. This structure prevents the occurrence of cracking in the sensor element 110, compared with a conventional sensor structure having a double-layered protective cover.

摘要： A compact, inexpensive static induction thyristor (SIThy) which is less likely to be broken down at a high voltage rise-up rate during operation and which is used in a high-voltage pulse generator capable of generating a high-voltage short pulse is provided. Thicknesses and impurity concentrations of a base region and a buffer region are determined such that a peak voltage obtained by a peak current at which a punch-through state is brought about does not exceed a breakdown voltage of the SIThy. Such design can achieve an SIThy having a self protecting function of autonomously preventing its breakdown without compromising a turn-on performance in which the peak voltage does not drastically exceed the breakdown voltage of the SIThy even when the peak current increases. Further, a compact SIThy capable of generating a short pulse can be achieved by reducing a gate-channel current-carrying area to a minimum.
