Title: Manufacture of bipolar transistor
Inventor: NAKADAI TAKAKO
IPC: H01L29/73
Filed: 1991-02-19
Abstract: PURPOSE:To lower the base resistance while securing the breakdown strength between emitter and base in relation to the title manufacture of bipolar transistor especially for lowering the base resistance, CONSTITUTION:A recession 11 is formed in a collector region 1 and then an outer base region 9 is formed around the recession 11 by the solid diffusion of the impurities from a base leading-out electrode 3 while restraining the spread of the impurities in the lateral direction by the stepped part of the recession 11 so as to avoid the deterioration in the breakdown strength between emitter and base due to the contact between the emitter region 10 and the outer base region 9. On the other hand, the activating temperature or time in an inner base region 12 can be augmented by restraining the spread of the outer base 9 using said recession 11 to increase the spread amount thereof in the lateral direction so that the spread part may sufficiently come into contact with the outer base region 9 at low resistance while thickening the impurity concentration in the active base region for lowering the base resistance.

Title: Characteristics recovery method for piezoelectric actuator
Inventor: MASUDA MICHIYUKI
IPC: H01L41/22
Filed: 1993-02-12
Abstract: PURPOSE:To provide a characteristics recovery method for a piezoelectric actuator capable of recovering the characteristics which deteriorated by the use under high temperature. CONSTITUTION:Temperature of a piezoelectric actuator 1 is detected by a sensor 2 attached to the piezoelectric actuator 1, and this temperature signal is input to a detecting circuit 3. The detecting circuit 3 outputs an ON signal as detection signal to a control preamplifier 4 when the temperature signal during temperature falling at the piezoelectric actuator 1 is in the temperature range corresponding to 45 to 55% of Curie temperature and outputs an OFF signal when the temperature is outside this range. The control preamplifier 4, after receiving an ON signal, sends a signal with a voltage 1.1 to 1.4 times the rated voltage similar to that output by an amplifier 5 and sends a feedback signal to the amplifier 5 similar to that output by the amplifier 5 after receiving an OFF signal; and a voltage corresponding to the signal is applied to the piezoelectric actuator 1 from the amplifier 5. By doing this, repolarization occurs and the initial characteristics can be recovered.

IPC: G01D5/244
Filed: 1988-02-04
Abstract: PURPOSE:To judge the cylinder group speedily and free from error by judging if the output signal of a revolution angle sensor is in any group, by a standard signal corresponding to the battery voltage level supplied into a starter. CONSTITUTION:The level of the output signal (a) of a revolution angel sensor A and the level of a standard signal (b) corresponding to the battery voltage supplied from a standard signal generating means B are compared in a comparing means C, and if a>b, a detection signal of the crankshaft revolution position is generated. Further, when an engine is started, a selecting means D sets the standard signal (b) at an H-level in the intermediate value of the output signal values of the revolution angle sensor A which correspond to a specific cylinder group and other cylinder groups, and when the output signal of the revolution angle sensor A which corresponds to the specific cylinder group is obtained, switching to a low L-level is performed. Therefore, the cylinder group is judged by a group signal generating means E from the order of generation of the detection signal of the comparing means C, and a group judgement signal is outputted.

Title: Voice communication equipment
Inventor: IDE HIROYASU
IPC: H04B14/04
Filed: 1993-01-19
Abstract: PURPOSE:To provide a voice communication equipment which never transfers the useless voice codes in a silent state and can assure the talking with no sense of incompatibility. CONSTITUTION:A digital voice decoder 17 decodes the voice codes supplied from a transmission line decoder 16 for each frame, and the digital voice signals are sent to an adder 19. If the absence of the voice code is reported based on the voice presence information supplied from the decoder 16, no voice signal to be transmitted is confirmed. Thus the level of the voice code supplied precedently by one frame is sent to a noise generator 18. When the absence of the voice code is reported in the preceding way, the generator 18 outputs a noise signal of a level equivalent to the voice level supplied from the decoder 17 to the adder 19. Then the noise signal is transmitted to a voice processing circuit, etc., which are excluded out of the diagram.

Abstract: PURPOSE:To make high-precision matching of a mark by forming a region where an electronic beam matching mark is formed surrounded by a silicon removed part in such manner that a region for forming a device body is formed may be isolated with regard to an automatic matching mark when a semiconductor device is directly exposed by means of an electronic beam. CONSTITUTION:The point is such that a region where a matching mark for exposure with an electronic beam, is formed surrounded by a silicon removed part in such manner that said region may be isolated from a region where a device body is formed. For instance, a cavity formed on the surface of silicon itself is an isolation region for forming a matching mark and a silicon protrusion formed independently in said isolation region in an islandlike pattern, is a matching mark. In this case,  a protruded matching mark 502 is formed like an island in a silicon cavity 502.  The step of silicon is preferably equivalent to, for instance, 0.5-5mum. The distance  l from the matching mark to a surrounding wall drawing the isolation region shall  be free from any influence of the wall when the matching mark is scanned.

Title: Flange sheet surface polisher
Inventor: KATORI TAKANORI
IPC: B08B5/04
Filed: 1988-02-05
Abstract: PURPOSE:To improve working efficiency and to decrease exposure by constituting the polisher in such a manner that a magnet belt to be rotated by a motor mounted on a traveling carriage travels while said belt is attracted to bolts studded on the outside surface of a sheet surface and that the traveling carriage self-travels along the sheet surface. CONSTITUTION:The flange sheet surface polisher is so constituted that the magnet belt 23 is attracted to the stud bolts studded on the outside circumference of the sheet surface when the magnet belt 23 is rotated and that a polisher 33 travels and moves on the sheet surface when the magnet belt is successively rotationally moved. Namely, the polisher 33 is mounted on the traveling carriage 17. The polisher 33 progresses while the stud bolts are attracted by the magnet belt 23. The stud bolts constitute the orbit of the polisher 33. Cleaning and polishing of the main flange sheet surface of a reactor pressure vessel which are heretofore executed manually by an operator using grinding wheel are thus automatically executed with an electric motor as a driving source according to this device. The working efficiency is thereby improved and the operator's exposure is decreased.

Title: Method of etching precise appreciation
Inventor: WATABE HEIJI
IPC: H01L21/66
Filed: 1992-01-17
Abstract: PURPOSE:To appreciate on-the-spot observation in an etching process in atomic order and to measure an etching amount and an etching speed precisely by monitoring change of analysis pattern signal strength of RHEED (reflection high energy electron diffraction method) of a processing surface with time. CONSTITUTION:When etching is proceeded for each atomic or molecular layer, RHEED signal strength reflects smoothness of a surface of a processing object 103 and changes. This means that etching proceeds per layer to make a step retreat gradually since a step 105 of atomic layer level on a surface is active as energy against other smooth regions. Therefore, as for a soft etching method which does not use assist effect by large energy conversion, etching proceeds for each atomic/molecular amount under specified conditions. Accordingly, monitoring of RHEED signal strength during etching brings about etching speed by its oscillation period and an etching amount by its oscillation frequency.
