Inventor: AN HEISHUN
IPC: H01C7/12
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To constitute a low-capacitance chip varistor, by reducing the thickness of a varistor layer by using a printing method, and forming substrates which have such strengths and thicknesses that can remedy the strength of the varistor layer and low dielectric constants and do not give any influence on the characteristics of the varistor layer on one surface of the varistor layer. SOLUTION: A varistor layer 11 is formed by alternately piling a plurality of varistor coating layers 17 and each internal electrode 14, 15, and 16 upon another by using a printing method. Then, a laminated body is formed by putting the varistor layer 11 between ceramic substrates 12 and 12a so that the outer peripheral edge section of the layer 11 may be exposed on the four side faces of the laminated body. The substrates 12 and 12a have low dielectric constants and strengths and thicknesses sufficient to protect the layer 11 from external shocks. The one terminals of the internal electrodes 14 and 16 and 15 are respectively connected to external electrodes 13 and 13a. Therefore, a low-capacitance varistor is obtained by lowering the capacitance of a chip varistor.

Title: Information processor
Inventor: UDA TOSHIYUKI
IPC: G06F12/10
Filed: 1985-04-30
Abstract: PURPOSE:To prevent the fall into a meaningless page input/output repeating operation by reporting contents of an instruction progress state display means to an exception processing routine of software to perform the processing when an exception of an instruction occurs. CONSTITUTION:When the execution of one instruction is terminated in an operation control circuit 1, an instruction execution progress discriminating circuit 2 detects the end of the execution to reset an instruction progress state flag 3. In the case of the next instruction, the circuit 1 outputs the logical address of the operand of this instruction to an address calculation paging control circuit 4 to access a main storage 6 through a main storage interface 5 when this logical address appears. If a page including the designated logical address does not exist on actual addresses of the main storage 6, an operating system (OS) is interrupted by page fault. When accepting the interruption, the OS reads the state of the flag 3 which is supplied simultaneously, and the processing is performed according as the flag 3 is set or not, thus preventing the meaningless page input/output repeating operation.

IPC: G01N33/68
Filed: 1981-06-16
Abstract: PURPOSE:To analyze quantitatively singularly combined protein in high accuracy, by bringing an excessive quantity of physiologically very small quantity active substance such as hormone in blood serum is brought into contact with protein singularly combining with said substance and utilizing a competitive reaction of labelled substance of said active substance, protein an unlabelled substance. CONSTITUTION:In order to analyze quantitatively a protein P in a sample to be inspected (blood serum etc.) containing protein (the protein P) singularly combining with physiologically very small quantity active substance (substance A) such as hormone in blood, metals etc., a complex A-P is formed by adding the substance A to the sample exceeding the combination capacity with the protein P. Next, the compex A-P is separated from the excess substance A and is brought into contact with the substance A labelled by a fixed quantity of a radioactive element or enzyme and the substitution is carried out by performing a competitive reaction of labelled substance A of the complex A-P and unlabelled substance A of the complex A-P. Next, after labelled complex A-P is separated from uncombined labelled substance A, radioactivity of separated labelled complex A-P is measured and the protein P is determined accurately. The complex A-P is separated more easily by adding a singular antibody for the protein P together with the protein P and combining said antibody with the complex A-P.

Filed: 1984-05-10
Abstract: PURPOSE:To form a tape path with high accuracy even at the final going route position by giving going route revolutions to both the 1st and 2nd tape shift levers and securing the accurate going route movement of a tape shift component between the intermediate and final going route positions. CONSTITUTION:When a stop button is pushed, a cam brake plunger 100 and a pinch roller pressure contact plunger 61 become inactive. Therefore the breaks are applied to a supply reel turntable 12 and the brake is released for a tape shift cam pulley 75. At the same time, pinch rollers 41 and 42 get away from capstans 131 and 132 respectively. A tape shift motor 80 is started to revolve the pulley 75 counterclockwise, and an action pin 77 is also rotated in the same way up to the coming-back route position. Thus a lever 73 which is not driven by the force of a spring 74 is also rotated in the coming-back route. As a result, the coming-back motions are applied to pinch levers 45 and 46, an action lever 47 and the 1st and 2nd intermediate levers 53 and 54 respectively. In this case, a slackened tape is taken up by a take-up reel 17.

Filed: 1992-03-18
Abstract: PURPOSE:To reduce the generation of overcurrent of a permanent magnet and a yoke by specifying specific resistances of permanent magnet blocks and electrically and integrally insulating each permanent magnet block. CONSTITUTION:Permanent magnet components 2a and 2b which are trapezoid- shaped in the cross section and provide a magnetization orientation in a vertical direction (top and bottom) are laid out in the upper and lower opposed planes in a hexagonal cylinder-shaped yoke. Permanent magnet components 2c, 2d, 2e and 2f having a triangle-shaped cross section and a magnetization orientation in a lateral direction, are laid out in the shape of a ring which allows the permanent magnet blocks 2b, 2c, 2e and 2f to be laid out on the circumferential plane in the yoke 1. Each permanent component insulates each of R-Fe-B rare earth magnet blocks electrically and integrate them in one piece. The specific resistance of the permanent magnet blocks is specified to be 10<-3>OMEGA m and below. The yoke consists of a laminated body of silicon steel plate. This construction makes it possible to inhibit the generation of overcurrent which generates permanent magnets and yokes without dropping the magnetic field strength even if the frequency is raised.

Title: Amplifier
Inventor: KOYANO ATSUSHI
IPC: H03G11/08
Filed: 1989-04-13
Abstract: PURPOSE:To independently shift the change points of an input/output characteristic in respectively different directions by installing first and second bias current change means. CONSTITUTION:Differential amplifiers A-C and an output stage amplifier D are provided. When a variable resistance RA is adjusted and the current quantity of variable bias current sources I1 and I2 is adjusted, an input dynamic range changes with the peak value and the bottom value of the synthesized input output characteristic of the differential amplifiers B and C in a state that they are held constant. When a variable resistance RB is adjusted and the current quantity of variable bias current sources I0 and I3 is adjusted, the input dynamic range of the synthesized input output characteristic of the differential amplifiers B and C is held constant, and only the peak value and the bottom value change. Thus, the shift of the change point of the input output characteristic for a parallel direction with respect to the input output characteristic linearity of the differential amplifier A and the shift for a vertical direction can be independently adjusted.
