Title: Bipolar transistor element
Inventor: NAKAYAMA YASUHIRO
IPC: H01L21/331
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a power transistor which can control a large current without increasing the area of a chip by forming the depth of a base layer of a region not formed with an emitter layer shallower than that of the base layer of a region formed with the emitter layer. CONSTITUTION:Since a base layer 5a of a region not formed with an emitter layer 3 is formed shallower than a base layer 5b of other part, the resistance of the layer 5a disposed to the layer 3 is raised. Thus, it becomes the same state as the state in which a ballast resistor is inserted between a base.emitter junction and a base electrode 2, and a current is not concentrated at a specific unit transistor. It is not necessary to provide a diffused layer for the resistor in the layer 5a to the layer 3 separately from the layer 5a. Thus, it is not necessary particularly to provide a diffused layer for the resistor, and a large current bipolar transistor element having a multiemitter structure in which a current is not concentrated at the specific emitter layer can be obtained.

Abstract: PURPOSE:To increase the speed of operation of a bipolar transistor remarkably by forming a diffusion layer in concentration lower than a high-concentration buried layer before shaping the high-concentration buried layer and interposing diffusion layer in low concentration between a collector and a substrate. CONSTITUTION:A thin oxide film 11 is formed on a semiconductor substrate 1 consisting of P-type silicon, and the ions of an N-type impurity are implanted selectively to a section to which an N-type buried layer must be shaped first through the oxide film 11 and diffused, thus forming a low-concentration diffusion layer 12 as a first buried layer. The ions of the N-type impurity are implanted similarly to said low-concentration diffusion layer 12 section through the oxide film 11 and diffused, thus shaping a buried layer 2 in high concentration on the inside of the low-concentration diffusion layer 12. The oxide film 11 on the surface of the substrate 1 is removed, the ions of a P-type impurity for a channel stopper are implanted selectively to the peripheries of the buried layer 2 and the low-concentration diffusion layer 12 and diffused to form a P<+> type channel stopper layer 3, and a photo-resist as a mask is removed.

Abstract: PURPOSE:To enhance the efficiency of printing work, by constituting the title apparatus so that a printing means and a display means are provided on printing paper in a relatively movable manner and the content to be printed on the printing paper is displayed on the display means corresponding to a position and a display range. CONSTITUTION:When a carriage 5 reaches the position LL on a paper 4 when a document is prepared with respect to the paper 4 as shown by a drawing, AB is displayed on a liquid crystal 3 at a preliminarily laid-out position. When the carriage 5 reaches respective positions MM, NM, CD and EE are respectively displayed. When the carriage 5 is present at a position other than said positions, any one is not displayed on the liquid crystal 3. Since the content displayed on the liquid crystal 3 is smoothly scrolled in matching relation to the moving speed of the carriage 5 when the carriage 5 moves, the state of the preparation of the document can be accurately and rapidly confirmed. When printing is indicated in this state, the carriage 5 successively moves to the positions LL, MM, NN to print AB, CD and EF respectively. As a result, printing operation becomes easy.

Title: Setting method of roll speed
Inventor: ISOBE KUNIO
IPC: B21B37/52
Filed: 1990-03-02
Abstract: PURPOSE:To manufacture a warm rolled stock of good dimensional accuracy by setting a roll speed by using the forward slip for hot rolling in the rolling in a temp. range not less than transformation temp. and using the forward slip for warm rolling in the rolling in the temp. range less than transformation temp. CONSTITUTION:In the case hot rolling and successively warm rolling are applied to a material to be rolled, the Ar3 transformation temp. is determined. And, in the rolling in the temp. range not less than the transformation temp., the circumferential speed of roll of each stand is decided by calculating by the formula of forward slip for hot rolling. In the rolling in the temp. range less than the transformation temp., the circumferential speed of roll of each stand is decided by calculating by the formula of forward slip for warm rolling and a strip is passed through. In this way, because the roll speed of each stand can be set in a good balance to the material to be rolled, the variance of tension when passing the strip through is small and the warm rolled stock of good dimensional accuracy can be manufactured.
