Title: Emitter follower circuit
Inventor: KAMIKO MITSUO
IPC: H03F3/34
Filed: 1981-09-29
Abstract: PURPOSE:To attain low power consumption and low distortion, by adding a negative feedback circuit consisting of resistors and transistors (TRs). CONSTITUTION:An emitter follower circuit is constituted of a TRTR1 and an emitter resistor RE connected to the emitter. A feedback resistor Rf is connected to the collector of the TRTR1, and the base and collector of a TR2 are respectively connected to the collector and emitter of the TRTR1 and to constitute a negative feedback of the resistor Rf and the TRTR2. Through the negative feedback, a base to emitter voltage VBE of the TRTR1 can be kept almost to a prescribed voltage value, independently of the input signal. Since an output voltage is expressed equal to the input voltage -VBE, the output voltage without distortion can be obtained. Since the collector current of the TRTR2 flows to the emitter resistor RE, the output impedance is made sufficiently smaller than the case without the negative feedback circuit.

Abstract: PURPOSE:To perform emulation by complete single-step operation by inserting a no-operation instruction forcibly every time a target instruction is executed, and by generating an interruption which can not be inhibited during the instruction execution. CONSTITUTION:Every time a microprocessor 1 executes one of program instructions stored in a storage device 3, it reads a no-operation instruction out of a no- operation instruction storage device 15 to a data bus 4, thereby executing this no- operation instruction. Then, a request for an interruption which can not be inhibited is sent, in response to a signal from a status detecting circuit 10, to a microprocessor 1 through an interruption signal selection circuit 12 at a point in time a little bit behind the execution start of the no-operation instruction. This request for the interruption returns the control from the execution of the instructions stored in the storage device 3 to a control program in a storage device 2.

Abstract: PURPOSE:To produce a nonoriented silicon steel sheet excellent in magnetic properties after stress relief annealing by subjecting a steel having a specific composition consisting of C, Si, and Fe to hot rolling and to cold rolling at specific temp. and then subjecting the resulting steel sheet to continuous annealing and further to specific skin pass rolling. CONSTITUTION:A steel having a composition consisting of, by weight, <=0.010% C, 4.0-8.0% Si, and the balance Fe with inevitable impurity elements is hot-rolled and then subjected, if necessary, to hot rolled plate annealing at 750-1,200 deg.C for 15sec-5min. Subsequently, this hot rolled plate is cold-rolled once or is cold-rolled twice or more while process-annealed between the cold rolling stages at 100-300 deg.C rolling temp. Continuous annealing is applied to the resulting cold rolled sheet to carry out recrystallization and crystalline grain growth. Skin pass rolling is further applied to this steel sheet at 2-15% reduction of area, by which crystalline grain growth at the time of stress relief annealing can be accelerated. By this method, magnetic properties can sufficiently be improved even by short-time stress relief annealing, and the nonoriented silicon steel sheet excellent in magnetic properties after stress relief annealing can be obtained.

Abstract: PURPOSE: To enable easy cutting-out of the parts by a method wherein a support loaded with a plurality of parts in a longitudinal line is simply made to conduct a vertical reciprocating motion.  
     CONSTITUTION: When slide plates 11a and 11b are made to conduct an upward motion and then a slant motion around a supporting shaft 12 by the eccentric cam 16 of a shaking part 8, a parts piece 1 slides down on the slide plates by its own weight and the band plate 2' of the parts piece 1' positioned in the forefront is attracted to a magnet 9, whereby all the parts 1 stop sliding. When the eccentric cam 16 is further rotated, the slide plates are lowered. However, since the parts piece 1' in the forefront is attracted to the magnet 9, it is left being attracted, while the subsequent part piece 1 is lowered, and thus the part piece 1' is cut out from the rest. Then, the magnet 9 is drawn by a cylinder 10 and thereby the article 1' is taken out from the support 7.

Title: Hysteresis comparator
Inventor: KATAYAMA TAKESHI
IPC: H03K3/0233
Filed: 1990-06-13
Abstract: PURPOSE:To make it possible to compare the voltage of an input signal with a reference voltage at a high speed under the state wherein the temperature change is small by making the operating speed high, determining the width of hysteresis and the central voltage readily, and using a hystersis comparator which can remove the fluctuation in comparing voltage due to temperature. CONSTITUTION:When the base voltage of a transistor 1 becomes higher than V1', the transistor 1 is turned ON, the collector voltage is decreased, the base voltage of a transistor 2 is decreased and the transistor 2 is turned OFF. At this time, the base voltage of the transistor 2 becomes V2'. The V1' and the V2' can be expresses as V1' = VCC - VBE - I2R14 and V2' = VCC - I1R12 - VBE - I2R14, respetively. Therefore, the width of the hysteresis and the central voltage become the hysteresis width of I1R12 and the central voltage of VCC -VBE - I2R14 - I2R12/2. When the hysteresis width is determined at first, the mutual influences are eliminated, and the two values can be readily determined.

Title: Production of heat insulation structure for high temperature
Inventor: SAITO YASUO
IPC: C04B38/00
Filed: 1990-06-14
Abstract: PURPOSE:To enhance thermal stability and high-temp. strength by mixing polycrystalline high alumina fiber wherein alumina content is specified and specifying composition in the case of adding alumina powder and colloidal silica to ceramic fiber and molding the mixture. CONSTITUTION:A heat insulating structure for high temp. is produced by adding alumina powder and colloidal silica to ceramic fiber mixed with polycrystalline high alumina fiber (referred to as AF) and molding this mixture. In this case, alumina content in AF is regulated to 70-80% by weight. The ratio of AF, alumina powder and colloidal silica is shown as follows. 0.05<=Al2O3/AF<=10, 0.15<=SiO2/AF<=2. When alumina content of AF is less than 70%, a shrinkage factor at high temp. (above 1600 deg.C) is enlarged. When it exceeds 80%, the lowering effect of the shrinkage factor due to addition of alumina powder is not made remarkable and the production stage of AF is complicated. When Al2O3/AF is less than 0.05, the shrinkage factor at high temp. is enlarged. When it exceeds 10, heat insulation properties at low temp. (<=1000 deg.C) are deteriorated. When SiO2/AF exceeds 2, the shrinkage factor at high temp. is enlarged and heat insulation properties at low temp. are deteriorated. When it is less than 0.15, strength at the time of calcination at the intermediate temp. (e.g. 500 deg.C) is not sufficiently complemented.
