The gas supply-exhaust system 100 supplies a freezing gas and a defrosting gas to a probe 60 of the freezing probe system 300 to freeze and defrost the treatment portion surrounding the tip of the probe 60 by the Joule·Thomson effect. The control system 200 controls the gas supply-exhaust system 100 and makes treatment planning data for this control. The treatment planning data includes a freezing·defrosting sequence to determine the freezing period and the defrosting period. The determination of this sequence is performed by the computer in the control system 200.

    摘要: The present invention is directed to effectively prevent "load short-circuit breakdown" of a power Darlington transistor. When a potential different between a base BX and emitter E at a final stage of a power Darlington transistor (20) is at a specified level of voltage determined by base-emitter forward voltage of a protective bipolar transistor (32), the protective bipolar transistor (32) turns on, and accordingly, base current I.sub.B at an initial stage of the power Darlington transistor (20) is bypassed to the emitter E at the final stage. Hence, excessive rising of collector current I.sub.C of the Darlington transistor (20) is suppressed, and "load short-circuit breakdown" is prevented. The potential difference does not depend upon the number of stages of the Darlington transistor nor temperature, and therefore, it is facilitated for Darlington transistors of various numbers of stages to design a short-circuit protective circuit to ensure a specified bypass operation in the whole range of working temperature.

    摘要: A semiconductor device has an active portion having at least one well region in a semiconductor layer, and a breakdown voltage maintaining structure surrounding the active portion. The maintaining structure includes a conductor layer over each of a plurality of guard rings with an insulating film interposed in between and connected to the respective guard ring. An inner side end portion of each conductor layer projects over the immediate adjacent inner side guard ring. The impurity concentration of the guard rings is set between the impurity concentrations of the semiconductor layer and the well regions. A field plate can extend over the innermost conductor layer with the insulating film interposed in between. The field plate is in contact with the outermost well region and is in contact with the first conductor layer. The outer side end of the field plate extends outwardly beyond an outer side end of the innermost conductor layer. With these arrangements, the guard rings can be shortened and the chip size can be reduced. Furthermore, the device can be made less susceptible to external charge.

    摘要: In an instrument panel arrangement, a first permanent fixture is attached a second permanent fixture via a latch mechanism including a latch member engaging the first permanent fixture to the second permanent fixture and a handle member for selectively disengaging the latch member. The latch system allows the first and second permanent fixtures to be installed and removed in a simple manner, and this not only simplifies the assembly and maintenance work, but also facilitates the work in separating component parts for recycling when discarding or scrapping the automobile.
