Granted: 1998-04-23
Abstract: 2.1 The quiescent current of a push-pull output stage is automatically adjusted by providing a sensing element in each branch of the output stage. The two voltages measured across the sensing elements with respect to reference potential are input to a differential amplifier stage, the output voltage of which is compared with a reference value with the aid of a comparator. The circuit exhibits a frequency-dependence of the automatic quiescent-current regulation due to the cut-off frequency of the output transistors used. 2.2 To avoid this frequency-dependence, a phase-rotating section is connected to one input of the differential amplifier, which worsens the common-mode suppression of the differential amplifier at high frequencies. The result of this measure is that the frequency- dependent error is compensated. 2.3 Push-pull output stages with quiescent-current control. <IMAGE>

Abstract: On an end part of the nozzle (23) is produced a joint surface (24) of frustoconical shape whose axis coincides with the axis of the nozzle, which has a half-angle at the apex close to 45 DEG  and a cross-section decreasing in size towards the end of the nozzle (23). On the wall (20) member is produced a joint surface (25) of frustoconical shape corresponding to the shape of the joint surface (24) of the nozzle. The joint surfaces (24, 25) are placed so as to coincide, the nozzle and the wall member are welded with an electron beam in a single run and without additional metal, along their joint surfaces (24, 25) starting at the side of the wall (20) onto which opens the widened part of the joint surface (25) of the opening (22). The invention is applied in particular to the fastening of nozzles (23) to a nozzle-carrier belt (20) of a pressurised water nuclear reactor vessel.

Abstract: 본 발명은 수소에 의해 텅스텐 헥사플루오라이드를 환원시킴으로써 기판의 표면상에 텅스텐층을 설치하는 반도체 장치 제조방법에 관한 것이다. 
     본 발명에 따라서, 시레인에 의한 텅스텐 헥사플루오라이드 환원에 의해 기판 상에 텅스텐 층을 먼저 설치함으로써 기판의 텅스텐의 접촉 저항이 상당히 감소된다.
