IPC: H01J23/10
Filed: 1980-09-12
Abstract: PURPOSE:To prevent the breakdown of a filament by fixing two screws on the diagonal line of an underboard while penetrating through the corresponding hole of an upperboard while fastening two screws on the other diagonal line thereby reducing the vibration to be transmitted from the upperboard to the lowerboard. CONSTITUTION:When securing an upperboard 61 and a lowerboard 71 constituting a magnetic circuit, two screws 81, 82 on the diagonal line of the lowerboard 71 are secured through the caulking or the burrying and penetrated through the corresponding hole 61a of the upperboard 61. A hole 71a is provided on the other diagonal line of the lowerboard 71 while a tap hole 61b is provided through the corresponding upperboard 61 and fastened by means of the screws 83, 84. In other word  the fastening of the upperboard 61 and the lowerboard 71 is performed only at two points. Consequently the transmission of the vibration from the upperboard 61 to the lowerboard 71 is reduced to prevent the breakdown of the cathode section filament.

Title: Fluid supply system
Inventor: UCHIKAWA YASUO
IPC: F17D1/08
Filed: 1986-05-31
Abstract: PURPOSE:To perform efficient control over valves, by determining the number of valves in such a manner that the residual pressure that is obtained by deducting a sum of a pressure loss in a fluid supplying pipe between the starting point and the valve situated on the most-upstream side and that between the valve situated on the most-upstream side and the valve situated on the most- downstream side from the initial pressure exceeds the minimum, critical pressure required. CONSTITUTION:The number of valves are determined in such a manner that the pressure of the fluid being discharged from a valve 23 situated on the most- downstream side in the block, which is performing the fluid-discharge, exceeds the minimum, critical pressure HL that is necessary for achieving the flow-rate q desired, even when various kinds of pressure losses are deducted from the initial pressure at the fluid supplying source. With this, the flow rate of the fluid discharged from individual discharging valves 23 can be made almost uniform, and it becomes unnecessary to adjust the opening of the discharging valve 23 from block to block, thereby reducing both time and count required for controlling the valve. Thus, efficient control over the valves can be maintained.

Title: Driver for integrated circuit card
Inventor: MATSUSHITA AKIRA
IPC: G06K17/00
Filed: 1985-06-11
Abstract: PURPOSE:To attain the stable drive of an integrated circuit IC card with high performance by using electromagnetic waves as a transmitting medium to perform writing/reading operations of information signals and the supply of the operating power to the IC card having no terminal. CONSTITUTION:When data is written on an IC card A from a driver B, the serial data sent from a data processing part 1 is supplied to an F/S modulation circuit 4 which is driven by an oscillation circuit 2 for power transmission. The data is converted into an F/S frequency by the circuit 4 and transmitted through a power transmission coil 6 in the form of an electromagnetic wave after power amplification received via a power amplifier 5. Then the electromagnetic wave is received by a power reception coil 10 of the card A from the coil 6 and converted into a DC power supply E via a rectifying/smoothing circuit 11. This power supply E is also used for data processing via an F/S wave detection circuit 8. While the information is read out in the same way. This eliminates a trouble like a malfunction, etc. due to defective contact of a connection terminal. Thus the card A can be driven stably and with high performance.

Title: Gate turn-off thyrister
Inventor: AZUMA MINORU
IPC: H01L29/10
Filed: 1979-10-03
Abstract: PURPOSE:To achieve high breakdown voltage, high current and low ON voltage at the same time, by varying thickness of N type base layer of the gate turn-off  thyrister. CONSTITUTION:An N base 23, a P base 22 and an N emitter 21 are piled on a P emitter 24, a cathode electrode 25 is attached onto the N layer 21, a gate electrode 26 is attached onto the P base 22 and an anode electrode 27 is attahced onto the P layer 24. At this time, layer thickness Wnb of the N base 23 of a region 28 under the center of the cathode electrode is to be larger than layer thickness W'nb in a region 29 other than the region 28. When positive pulse is applied to the gate electrode 26, as the layer thickness W'nb is thin, current of low ON voltage passes at first a section 30 in the neighborhood of the gate electrode 26 under the cathode electrode 25, and then it uniformly passes under the electrode 25. While current is concentrated at the center section 28 under the electrode 25 which is far from the gate electrode 26, since the layer thickness Wnb is thick, series resistance is large and therefore concentation of current can be prevented. It is possible, by using this constitution, to obtain the gate turn-off thyristor of high breakdown voltage, low ON voltage and high surge current resistance.

IPC: F04B39/00
Filed: 1980-09-12
Abstract: PURPOSE: To prevent scoring from occurring between a rotary shaft and a bearing part by a method wherein the rotary shaft on the side of a front-side block or one of bearing holes provided in the block supporting the rotary shaft is provided with a tapered surface such as to increase a clearance in an outward direction.  
     CONSTITUTION: The bearing hole 5A rotatably supporting the rotary shaft 7A of a rotor on the side of a front-side block is provided with the tapered part 5B such as to gradually increase the clearance in the outward direction toward a front head 3, and the right-side part of the bearing hole 5A is contracted when it is cooled by a coolant gas of low pressure and low temperature which is sucked in through a suction port 11. However, when the coolant gas is sucked into a cylinder 4 through suction ports 8, 8 and compressed by the rotation of the rotor 7, the temperature and the pressure of the gas are increased and the left-side part of the bearing hole 5A is expanded. Although the clearance between the rotary shaft 7A and the bearing hole 5A is slightly reduced as a result of the thermal deformation, the tapered part 5B of the hole 5A serves to leave a sufficient clearance for forming a film of a lubricating oil between the shaft 7A and the hole 5A. Accordingly, it is possible to prevent the scoring from occurring between the rotary shaft 7A and the bearing part.
