Abstract: PURPOSE:To reduce the widths of emitter layers to contrive the improvement of a controllable current without increasing the number of rectangularly projected segments by a method wherein a low-impurity concentration base layer has a rectangularly projected part, a plurality of the rectangular emitter layers of a second conductivity type are formed in the surface layer of the base layer and a high-impurity concentration base layer is formed in such a way as to cover the surface of the low-impurity concentration base layer excepting the periphery of each emitter layer. CONSTITUTION:A p-type base layer is projected on an n-base layer 2 on a p<-> emitter layer 1 to form segments. This p-type base layer is constituted of a low-impurity concentration p<-> base layer 31 and a high-impurity concentration p<+> base layer 32. A narrow n<+> emitter layer 4 is dividedly buried in these segments, the divided emitter layers 4 are encircled with the projecting part of the layer 31 and moreover, the peripheries of the layers 4 are encircled with the layer 32. Even when the layer 4 is divided or even when the divided layers 4 are coupled with one another, one cathode electrode 6 consisting of Al, for example, is in contact with the part of each emitter layer at the apertures of an oxide film 8.

Abstract: PURPOSE:To make it possible to make the input current of a differential amplification part small and also to minimize the error of an output voltage to an input voltage by composing the circuit of 1st and 2nd differential input stage elements arranged symmetrically with a common emitter. CONSTITUTION:The circuit consists of left half 54 and right half 58 constituting voltage follower circuits respectively and are composed of differential input stage transistors TrQ1 and TrQ4, and TrQ8 and TrQ10 with common eitters arranged symmetrically, constant-current supplies 51 and 55, load elements 52 and 56 composed of TrQ2 and TrQ3, and TrQ7 and TrQ9 constituting current Miller circuits, and output TrQ5 and TrQ6. In this constitution, the offset voltage of the differntial amplifier composed of Trs Q1 to Q5 causes an error of linearity of this circuit, but the error is 0.164% and one-figure smaller than 1.3% of a conventional emitter degenerative amllifier. As for TrQ1, input current Iinl of 50A is nearly constant and much less and excellent in comparison with 0-2muA of the conventional emitter degenerative amplifier and 20muA of a Van de Plasche circuit.

Filed: 1987-04-24
Abstract: PURPOSE:To safely protect a fluorescent screen, and also, to know the center of a beam by attaching both the fluorescent screen and an absorption plate to one piece of member, and varying continuously thickness of the absorption plate. CONSTITUTION:A fluorescent screen 2 and an absorption plate 3 made of aluminum formed as one body with said screen are inserted simultaneously by a handle 5 into an optical path of synchrotron radiant X-rays in a vacuum duct 1. In this case, in the vertical direction of the absorption plate 3, its thickness is varied continuously. In this state, brightness of the fluorescent screen 2 is observed through an observation window 4 of glass. In such a way, at the time of inserting the fluorescent screen 2, the fluorescent screen 2 can be protected safely without forgetting to put in the absorption plate 3, and also, they can be taken in and out upward and downward simultaneously, therefore, trouble is saved. Also, by looking at a range where the fluorescent screen 2 is bright, a wavelength distribution can be estimated, and the center of a beam being the limit of short wavelength can also be known.

Abstract: A sliding gate valve (5) has a frame with a sliding carrier (11) within the frame, a stationary plate secured at an upper portion of the valve and a slide gate plate (16) secured at a lower portion of the valve. In one embodiment a spring plate (12) is provided with beam springs mounted in cantilever fashion with their end portions orientated in surrounding relationship to a teeming opening of the valve. In addition, a cluster (28) of such springs is provided at a shut-off portion of the slide plate which underlies the teeming opening to the vessel in the shut-off position. This mounting may be reversed with the springs secured in cantilever fashion to the carrier and the spring plate eliminated, while the springs bear directly on the underside of the metal encased refractories (19). The spring plate can have the cantilever springs mounted on both sides and is positioned between the slide gate plate and the carrier. This results cutting the spring rate in half. By providing double springing, such as reversely folding a pair of springs upon each other, also cuts the spring rate in half. With spring pairs mounted on each other on one side of the spring plate and a single spring on the other side, the spring rate is cut to one-third of that of a single spring. To cut the spring rate to one fourth, doubled springs are used on both faces of the spring plate.
