Title: High frequency unbalance inspecting method of transistor
Inventor: TAKEUCHI TOSHIHARU
IPC: G01R31/26
Filed: 1983-02-08
Abstract: PURPOSE:To execute easily a discrimination which is suitable for a practical use by detecting a discontinuity to frequency. CONSTITUTION:A signal which is subjected to a frequency sweep at a constant speed through a sweep oscillator 1 of a constant level output by a feedback control, an isolator 7, etc. is impressed to a transistor 8 to be inspected. Subsequently, an output amplified by the transistor 8 is detected by a detector 12, and thereafter, processed by a differentiating circuit 13. As a result, in case when the transistor 8 is ill-balanced, a discontinuity is generated in a frequency characteristic, a pulse corresponding to a sudden variation following said scontinuity is generated from the circuit 13, and a generated pulse is counted by a counter 14, by which it is possible to execute easily a decision which is suitable for a practical use as to whether a high frequency balance of the transistor is good or not.

Title: Preparation of heat-shrinkable tubing
Inventor: MURAKAMI TETSUO
IPC: B29C55/24
Filed: 1986-01-31
Abstract: PURPOSE:To enable preparation of a heat-shrinkable tube with a small shrinkage factor in the axial direction to be effected by placing a tube material on a carrier belt set in a heating zone heated by system and carrying it to take-up rolls, and by stretching it after that. CONSTITUTION:Lengthwise extension of a tube material, which may occur its own weight and/or the contacts of each part of the device when it is heated to the stretching temp. while being carried continuously, can be prevented by carriage on a carrier belt 3. It can be also stretched in the radial direction with an extremely small elongation in the axial direction by stretching it after once nipping with take-up rolls 4. This stretching in a radial direction is carried out to introduce the tube into a cooled device 5 for controlling the outside diameter, for example, just after the material passes through the take-up rolls 4. Consequently, it can be stretched continuously to a specified diameter by internal pressure of pressurized air enclosed in the tube between the following nip rolls 6.

Title: Detecting and protecting circuit of synchronizing signal
Inventor: TAKEUCHI TAKASHI
IPC: G11B20/10
Filed: 1982-02-12
Abstract: PURPOSE:To eliminate the misdetection of a synchronizing signal and to prevent the generation of a failure sound, by switching a window for synchronizing signal detector wider at the start of a disc driving motor starting and narrower at the stable steady-sate of the motor rotation. CONSTITUTION:The synchronizing signal is inputtd from a signal input terminal IN and a clock is inputted from an input terminal MCK, and the protected synchronizing signal is outputted from an output terminal OUT. When a switching control input terminal S is O level, decoded outputs 11A, 11C and 20A are inhibited. Since the output of an inverter 32 is 1 level, the output of AND circuits 29B, 30B and 31B are decoded outputs 11B, 11D and 20B. They are applied to latches 12, 21 via OR circuits 29, 30, 31. The range of input inhibition is widened and the window or detection is also widened after the synchronizing signal is inputted, by changing the decoded value of the output of counters 10 and 19.

Title: Control system for instruction pre-reading direction of pipeline system computer
Inventor: NARIMATSU HIROSHI
IPC: G06F9/38
Filed: 1988-01-30
Abstract: PURPOSE:To ensure an effective pre-reading process without complicating the hardware and the prior process by rewriting the instruction pre-reading direction instruction information in accordance with an actual branching destination at execution of a branch instruction. CONSTITUTION:A branch instruction is given to a block 9 where the arithmetic result is written and the block 9 writes a branch instruction to be given to an address (m) where the instruction received from the address (m) into an address (n). In other words, the branch instruction of the address (n) is rewritten into an instruction including the information which performs the pre-reading through the address (n) from an instruction including the information which performs the pre-reading through an address (n+1). This rewriting process, however, is carried out only in case the instruction pre-reading direction is different from the actually branched direction.

Title: Plasma treatment device
Inventor: SATO YASUE
IPC: H01L21/302
Filed: 1989-01-31
Abstract: PURPOSE:To prevent sputtering of material constructing a vacuum container (e.g. heavy metal such as Fe, Cr, Ni, etc., which considerably deteriorates the performance of a semiconductor film) to cause the material to be mixed in the plasma by covering the surface, to be in contact with plasma in the vacuum container, with a superconductor. CONSTITUTION:The inner wall surface of a vacuum container 1 to be in contact with plasma (e.g. a part of, or whole surface surrounding the space, in which a magnetic field from a magnet is generated, or a surface adjacent or near said surface) is covered with a superconductive material 4. A magnetic field having magnetic lines of force 9 is generated in a plasma chamber 7 by magnet 8, but the magnetic field can not enter through the surface around the plasma chamber due to Meissner effect of the superconductive material 4 covering the surface. Accordingly, unnecessary sputtering does not occurs, because charged particles in the plasma chamber 7 are diffused along the magnetic lines of force and the magnetic lines do not enter the surface covered with the superconductive material. Thus, contamination due to heavy metal (Fe, Cr, Cu, etc.) from the vacuum container 1 and an electrode 3 can be eliminated.

Title: Drive device for dc motor
Inventor: YAMADA YOSHIMITSU
IPC: H02P7/29
Filed: 1986-01-31
Abstract: PURPOSE:To prevent the overdrive of a drive section for a motor by adjusting reference voltage for controlling output voltage from a regulator section in response to the change of the terminal voltage of a battery. CONSTITUTION:A stabilized power supply 24 converts the voltage VB of a battery 4 into stable voltage Vcc, and a regulator section 28 changes stabilized voltage Vcc into driving voltage Vd corresponding to reference voltage Vref. An overcurrent control command section 30 controls the regulator section 28 so as to limit output currents. Switching means 14, 16 operate as choppers by output voltage Vd from the regulator section 28, and the driving currents of a DC motor 2 are controlled. A reference-voltage regulating means 70 for controlling outputs adjusts the reference voltage Vref of the regulator section 28 in response to the voltage VB of the battery 4. Accordingly, the overdrive of a motor drive section can be prevented positively regardless of the revolution of a DC motor.

Abstract: PURPOSE:To provide a battery which consists of non-recoverable type structure breaking a sudden large current and is prevented from burst due to increase of an inner pressure by providing an external lid body having a gas vent hole connected to a safety valve in a sealing lid group of a battery. CONSTITUTION:When a decomposed gas is generated inside an armor can 1 by a heavy-current due to an over charge condition, the gas penetrates to a space between a lid body 29 and a safety valve 31 via a vent hole 28 of the internal lid body 29, so that its inner pressure is increased. When the inner pressure reaches the predetermined value, the safety valve 31 is pressed onto an external lid body 33 side. The safety valve 31 is formed of an elastic conducting body, and its downward curve is headed to the reverse direction (upward direction) by its elastic action and is released from the lid body 29, so that a positive electrode electric path is cut off. When the inner pressure increased much more, a valve membrane matching with a groove 34 of the safety valve 31 is broken, so that the decomposed gas is released to the outside through a broken part of the valve membrane and a vent hole 32 opened in the lid body 33.
