Abstract: ABSTRACT OF THE DISCLOSURE         A gate turn-off thyristor of a short-circuited emitter configuration comprises a semiconductor sub-strate of a PE-NB-PB-NE four-layer structure, wherein a PE-layer is short-circuited through a NB-layer and an anode.  The NB-layer includes heavily doped regions to which the anode is ohmic contacted with a low resistance.  The PE-layer is provided at a location at least covered by a projection of the NE-layer.  The thickness of the heavily doped regions is greater than that of the PE-layer.  The improved structure assures satisfactory gate turn-off characteristics, although the semiconductor substrate is not doped with a life time killer impurity.

Abstract: ABSTRACT OF THE DISCLOSURE    Integrate MOS circuits with and without MNOS transistors in silicon-gate technology are produced with overlapped contacts using a silicon nitride mask.  After production of structured SiO2 layer on a p- or n- doped semiconductor substrate to separate active transistor zones in accordance with the so-called LOCOS process, a silicon nitride layer is deposited onto the surface and is then structured so that the zones in which a gate oxide is to be produced, are uncovered and during gate oxidation, the surface of this structured silicon nitride layer is converted into an oxynitride layer.  In contrast to previously known processes, the invention provides self-aligned overlapped contacts with oversized contact holes.  The silicon-nitride layer functions as an etch-stop during etching of an intermediate oxide.  This avoids under-etching of the polysilicon during contact hole etching.  The overlapped contacts allow a substantial increase in the packing and integra-tion density of the so-produced circuits.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides an improvement in a pipeline control system for a computer. Thus, in such a system in which the flows of processings successively proceed through a plurality of processing stages, pre-determined tag data are given to each of the processing stages to simultaneously effect the processings through the processing stages so that a plurality of processing flows proceed successively while maintaining a time lag. With this invention, the improvement resides in storing the predetermined tag data in a plurality of tag registers during the step of executing a first sequence of operation flows in order to repetitively execute the flow of process-ing which is based on the same tag data. The required tag is selected from the tags stored in the tag registers in steps for executing second and subse-quent operation flows in which the same operation flows will be repeated. Thus, an execution is initiated from the second phase without executing the first phase. The system of this invention increases the operation speed of a pipeline computer system by eliminating the additional operation flow which has hitherto been employed when one instruction was to be switched to another instruc-tion.

Abstract: Abstract:    A process and apparatus are described for producing a modified carbohydrate material, preferably starch, in fluid form.  In the process a starch slurry is continuously moved through a confined tubular preheat zone where heat is very rapidly transferred to the slurry, whereby the slurry passes through a gelation stage and forms into a hot free flowing liquid.  The heat transfer is from super-atmospheric steam surrounding at least part of the tubular heating zone, the temperature of the steam and the cross-sectional area of each tubular preheat zone being selected to rapidly transfer heat from the steam throughout the slurry and minimize the magnitude of the zone of high viscosity gel formed during the gelation stage.  The hot liquid formed is immediately forced through a restrictive opening and into a confined tubular reaction zone accom-panied by a sudden decrease in pressure whereby the starch is made highly reactive.  The reactive starch liquid, together with   reactive adjunct such as acid, is then continuously moved through a tubular reaction zone to produce a modified starch product in fluid form.  A steam heated reactor for the above process is also described.

Abstract: 9.               MINIMIZATION OF STRAIN IN SINGLE CRYSTALS        Abstract of the Disclosure Single crystals are conveniently produced by directional solidification of a liquid body under a pressurized atmosphere and, preferably, under a liquid encapsulating layer to minimize loss due to volatilization. Such fabrication entails a concern with internal stress in a grown crystal in the interest, e.g., of minimization of breakage of wafers cut from a crystal.  According to the invention, minimization of stress is accomplished by means of a post-growth annealing step during which pressure is reduced substantially and, in particular, preferably to a pressure which does not exceed 50 percent of a pressure at which a constituent of the liquid body volatilizes.    The method may be applied for producing single crystals of semiconductor materials as may be used as device substrates.  In particular, the method is beneficial, e.g., for producing high-quality doped or undoped InP, GaP, and GaAs single crystals.
