Title: Differential amplifier circuit
Inventor: TAKEDA YOSHINORI
IPC: H03F1/52
Filed: 1989-05-31
Abstract: PURPOSE:To make the transmission characteristic of the circuit stable by providing a reverse bias preventing transistor(TR) whose collector connects to a power wire and keeping a level by a forward voltage drop between a base and an emitter of a differential pair TR to a prescribed bias at all times. CONSTITUTION:A reverse bias preventing TR Q3 is provided to a differential pair TR Q1. Then an emitter E3 connects to a base B1 of the differential pair TR Q1 and its base B3 connects to a connecting point between emitters E1, E2 of the TRs Q1, Q2 and a collector C3 connects to a power supply line Vcc. It is supposed that when an input voltage (e) being a negative abnormal voltage is invaded undesirably to the input system and the level is lower than the emitter level VE1 of the TR Q1, then the relation of VE1>VB1 exists in the TR Q3 which acts like increasing the base level VB1 of the TR Q1. Thus, the TR Q1 is protected from the invasion of a negative abnormal voltage and the deterioration is prevented.

Title: Manufacturing of resin mold coil
Inventor: MATSUMIYA YASUNORI
IPC: H01F41/12
Filed: 1979-10-29
Abstract: PURPOSE:To improve insulation characteristic by eliminating formation of voids, when viscosity of resin became lower in early stage of rotary gelation, by applying pressure to atmosphere surrounding a coil to allow the resin to permeate in the coil. CONSTITUTION:A resin-impregnated coil 1 is mounted on an axis 8, and a driving source 9 is given to the coil 1 to allow it to turn. And when the air in a furnace is heated by a heating source 6, this heat is conducted to the coil 1. By this heating process, viscosity of the resin is lowered. And then, as a valve 11 is opened, compressed air is introduced in the furnace to raise air pressure of the coil 1, and therefore, permeation of the resin is accelerated and vacuum voids are gradually eliminated.

Title: Control system for different processors
Inventor: NAGAOKA SHINJIROU
IPC: G06F15/177
Filed: 1985-06-25
Abstract: PURPOSE:To read out an instruction written by a self-instruction system directly and to execute an operation or the like by forming a control means for turning a CPU resigning a control right to a held state and turning the other CPU to an operating state. CONSTITUTION:When a power source is turned on, the CPU 1 is started and the CPU 2 is turned to the held state by a holding request circuit 3. When the CPU 1 outputs a control right resigning command, the CPU 2 is turned to the operating state. Namely, the circuit 3 controls the CPUs 1, 2 so that the CPU 2 is unheld and the CPU 1 is held. When a control right resigning command is outputted from the CPU 2, the CPU 2 is turned to the held state and the CPU 1 is unheld. Thus, the CPU 1 in the operating state is turned to the held state by resigning its control right and the control right is transferred to the CPU 2, so that the CPU 2 can read out directly the instruction written by the self-instruction system.

Abstract: PURPOSE:To avoid the damage of a layer insulation film on a fuse after fusing by a method wherein the fusing part of the poly Si fuse is covered with an SiO2 film or a dense insulation film adhered after removing the SiO2 film. CONSTITUTION:The conductive poly Si film 3 of a pattern having a terminal part 12 and the fusing part 11 is formed on an Si substrate 1 via the SiO2 film 2. When the SiO2 thick film 17 is formed only at the fusing part 11' by being covered with an SiO2 thin film 14, superposing an Si3N4 film 15, and opening a window through the film 15, the fuse of small fusing current can be obtained without increasing the resistance of the slender part. The film 15 is removed by etching and covered with an SiO2 18, and Al electrodes 19 and 19' and an SiO2 protection film 20. Or, after patterning the fuse, a part of the slender part 11 is left and covered with an Si3N4, and accordingly a thick film which is dense and good adhesion property can be formed by thermally oxidizing the aperture. This constitution enables to avoid the damage of the insulation film on the fuse after fusing by decreasing the fusing voltage without increasing fuse resistance to a large extent.

Abstract: PURPOSE: To measure dimensions at high precision by simple manipulation, by electrically detecting the coincidence of the contour of the subject displayed on a screen of video monitor or the like and the cursor line, and measuring dimensions electronically.  
     CONSTITUTION: The horizontal and vertical drive signals from a television camera CM to photograph the subject are processed in differentiating circuits DF 1 , DF 2 , AND G 1 , MULTI MV 1 , MV 2 , FF, etc. And a signal for one horizontal period is generated from FF 3 , and a horizontal line index 6 which intersects at right angles with two cursor lines 3, 4 is displayed in a monitor PM together with the image through mixers MX 1 , MX 2 . Moving the index 6 up and down, it is made to cross the measuring position of the subject image 2, and the cursor lines 3, 4 are made to move in the left and right direction, so that the cursor lines 3, 4 will annihilate when coinciding with the intersecting points 7A or 7B in the subject image 2. When the both cursor lines 3, 4 are annihilated, a counter CT makes an indication, from which the overall dimensions of the subject may be obtained. Hence, high precision measurements are realized.
