Abstract: PURPOSE:To rotatably support a shaft subjected to thrust load by forming a ring shaped projection the axial center of which is aligned with the center of either one of a surface formed in a rotating wheel made of ceramics and a surface formed in a stationary wheel made of ceramics. CONSTITUTION:A bearing A is so constituted that a rotating wheel 1 is combined with a stationary wheel 2, and the rotating wheel 1 is made up from a ceramic raw material in an oxide series such as alumina and the like while being pressed into shapes, and is calcined so as to be formed. The outer circumference of the rotating wheel 1 is formed with a cylindrical surface 1a in parallel with an axial center 5, and the cylindrical surface 1a shall be smaller in diameter than a cylindrical surface 2a which is formed in the outer circumference of the stationary wheel 2. The end surface of the rotating wheel 1 at the front end side shall be a flat surface 1b roughly normal to the axial center 5 and a ring shaped projection 6 of which center coincides with the axial center 5 is formed on the flat surface 1b. The height of the projection 6 shall be larger than the depth of a groove 7 formed in the stationary wheel 2. The projection 6 is coupled in the groove 7 while being slidably brought in contact with the groove 7 so that thrust load and the like acting on a shaft 3 is thereby transmitted to the stationary wheel 2.

Title: Controller for induction motor
Inventor: KAJITA TAKEYOSHI
IPC: H02P23/16
Filed: 1986-11-07
Abstract: PURPOSE:To obtain a good characteristic even in a controller, in which thyristors are inserted into two phases among primary three phases, by a method wherein the conduction angle of the thyristor and the speed of an induction motor are stored as parameters to make respective conduction angles substantially equal. CONSTITUTION:The speed omegam of a motor is converted into a digital value by an A/D converter 11 and is given to memories 8, 9. The speed omegam is compared with a speed command omegar and a deviation epsilon is amplified by an amplifier 7 to obtain an ignition phase command alpha while the command alpha is converted into a digital value by the A/D converter 10 and is given to the memories 8, 9. The ignition control of thyristors R-1, R-2, T-1, T-2 is effected by the control angles alphaR, alphaT of the thyristors in respective phases, which are read out by the memories 8, 9. In this case, the thyristors R-1, R-2, T-1, T-2 in the phases R, T are controlled by the same ignition phase command alpha, therefore, the conduction angles may be made equal to each other.

Abstract: PURPOSE:To prevent the generation of cracks in resin and to improve the reliability of a semiconductor device by a method wherein a highly water resistant thin film is provided on the rear of the surface, on which a semiconductor element is firmly bonded, of an element mounting part in such a way that it is bonded on the rear only at the end parts of the mounting part. CONSTITUTION:A water-resistant film 8 is adhered on the rear of an element mounting part 3, which is supported by suspension pins 2 connected to an outer frame 9 and wing leads 7, at the part of real diagonal lines. A semiconductor element 4 is firmly bonded on the mounting part 2 with a mounting brazing material 5 and is sealed with a resin 6. At this time, the mounting part 3 is adhered to the film 8 at its end parts, but the part other than the end parts of the mounting part 3 is isolated from the film 8. Accordingly, in the case a semiconductor device is heated and water content, which is concentrated on the rear of the mounting part 3, is vaporized, the vapor can be exhausted outside of the device. Thereby, the generation of a crack is suppressed and a reduction in the reliability of the device can be prevented.

Title: End plug of fuel rod and welding method thereof
Inventor: YONEDA HIDESHI
IPC: G21C21/02
Filed: 1994-10-28
Abstract: PURPOSE: To prevent the lowering of the ductility of a pipe and the deterioration of the quality of materials in a welding region due to a temperature drop. CONSTITUTION: A V-shaped recessed section 19 is formed between a press-fitting section 16 having a maximum outside diameter slightly larger than the inside diameter of a pipe and a welding section 17 having an outside diameter approximately equal to the outside diameter of the pipe in an end plug 15. The press- fitting section 16 of the end plug 15 is press-fitted to the inwall of the pipe, an inclined plane 17b on the front end side of the welding section 17 is resistance-welded under the state of pushing, in which the inclined plane 17b is abutted against the end face of the pipe, and a space 20 between the recessed section 19 and the inwall of the pipe is filled with an internal bulging section 16.  A temperature drop at the time of the operation of a nuclear reactor is reduced by the γ-heat generation of the press-fitting section 16 at one end section, to which the fuel pellet 7 of a fuel rod is abutted. Since the state of a high temperature by the press-fitting section 16 is brought to the other end section, the movement of hydrogen dissolved into the pipe to a welding region can be prevented.

Title: Discharge lamp lighting device
Inventor: MATSUMOTO AIJI
IPC: H05B41/282
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To improve the rate of inputs and to simplify a high voltage generating circuit for cost reduction by causing operation of a lighting device at a no-load resonance frequency that is characteristic of a piezoelectric transformer, and directly switching using a converter a pulsating current obtained through rectification of an ac input. SOLUTION: An alternating current inputted to an ac input circuit 1 having a high-frequency noise filter is rectified into a direct current for input to a converter circuit 2. Then the direct current enters an inverter circuit 3 and turns on an HID lamp; at initial stages, a high voltage is produced by a high voltage generating circuit 4 at a no-load resonance frequency which is characteristic of a piezoelectric transformer. A converter driving pulse width control circuit 5C compares an output voltage of the converter circuit 2 with that of a reference voltage generating circuit 5A via an error amplifier circuit 5B and amplifies the voltage differential. A load current detecting circuit 5D detects the load current of the HID lamp, and controls the converter circuit 2 so that the load current remains constant.  Therefore, the rate of inputs is improved, and the high voltage generating circuit is simplified to make cost reduction possible.

IPC: B25J13/00
Filed: 1990-10-05
Abstract: PURPOSE:To shorten workhours by using the two parameters of a discreteness and an operational possibility to automatically determine the holding sequence of plural articles placed randomly. CONSTITUTION:In the case where only one of articles having the same discreteness is selected, it is checked whether the article can be held at the computed steady holding position or not, and in the case where it can not be held, the steady holding position is computed again for holding and moving the article. When the whole of the articles 21-2n are concluded in their holding and moving processes, the process of the articles is ended, and when the above processes are not yet concluded, a step for selecting the article having the maximum discreteness will be executed again. In the case where plural articles having the same discreteness have been selected, it is checked whether each of the articles can be held at the computed steady holding position of the articles or not, and in the case where they can not held, the steady holding position is computed again, and operational possibility is then computed, and the process for holding and moving the article having the maximum operational possibility is repeated until the article having the same discreteness runs out.
