Title: Input device for controller
Inventor: KOIZUMI KOJI
IPC: G05B19/05
Filed: 1994-03-16

IPC: F04C18/02
Filed: 1992-03-02
Abstract: PURPOSE:To prevent the inflow of a returned liquid coolant and ensure the lubrication to an upper bearing by providing a liquid coolant receiver facing the opening part of the upper discharge pipe of an upper bearing housing, and providing an oil feed passage between the receiver and the bearing housing. CONSTITUTION:When a coolant discharged from a compressing element 4 is released to a high pressure chamber 7 through the air gap 2a of a motor 2, the discharged coolant is collided with the inner wall surface of a casing 1 to separate the lubricating oil mixed in the coolant, and the separated lubricating oil flows from the upper surface of an upper bearing housing 5 to a bearing 6 along a recessed part 51 forming an oil feed passage 10 to lubricate it. On the other hand, the high pressure chamber 7 has a liquid coolant receiver 9 for receiving the returned liquid coolant from the discharge pipe 8 facing the opening of the discharge pipe 8. When the liquid coolant from a coolant system is returned from the discharge pipe 8 to the high pressure chamber after the operation of the compressor is stopped, the returned liquid coolant is received by the liquid coolant receiver 9 to prevent the coolant from flowing from the oil feed passage 10 into the bearing 6, and the oil component of the bearing 6 can be prevented from being carried away by this inflow.

Title: Control method for hydraulic motor
Inventor: WATANABE EISUKE
IPC: B28B11/14
Filed: 1994-02-18
Abstract: PURPOSE:To reduce time of start-up and suppress fluctuation of rotational speed by accelerating a hydraulic motor by means of a hydraulic pressure generation device, correcting an output so as to set the detected rotational speed within an allowable deviation in respect to a preset value when the output reaches a preset value, and rotating the hydraulic motor with constant speed. CONSTITUTION:When a starting signal is confirmed, a hydraulic motor 7 is started and an acceleration pattern I is executed. This pattern is set with loose inclination so as to soften shock in an initial period of the start-up. When rotational speed of the hydraulic motor 7 reaches a preset acceleration changeover point, an acceleration pattern II is executed. This pattern is set with steep inclination so as to reduce the time of start-up. In the case that an output of a hydraulic pressure generation device 13 reaches a preset value, the rotational speed of the hydraulic motor 7 is detected by a rotation detector 14. When the rotational speed is within an allowable deviation of the preset value, correction is conducted so as to increase the output of the hydraulic pressure generation device 13. After obtaining the value within the allowable deviation, it goes to a constant speed rotation sub-routine. It is thus possible to reduce the time of start-up, and suppress fluctuation of the rotational speed at the time of the constant speed rotation thereafter.

Title: Superconductive accelerating cavity
Inventor: SHIMANO TAKASHI
IPC: H05H9/00
Filed: 1987-02-27
Abstract: PURPOSE:To improve the accelerating voltage of a superconductive accelerating cavity by making the axial electric field strength in the cavity to be lowest in the accelerating cavity at the intake of radio wave and increased gradually toward the outlet and highest in the accelerating cavity at the outlet of radio wave. CONSTITUTION:In a travelling wave type accelerating cavity the electric field is excited successively from the intake toward the outlet of radio wave, so the electric field is increased earliest at the intake and later toward the outlet. The exciting period is longest at the intake portion, so if the electric field is made uniform all over the cavity the field strength at the intake portion is built up to a high level by the time of completion of the excitation of whole accelerating cavity, and the accelerating voltage of whole cavity is determined depending upon the field strength at the intake portion. Therefore by distributing the electric field strength in the accelerating cavity so as to increase gradually from the intake toward the outlet, the accelerating voltage can be increased substantially. In order to make the accelerating electric field higher and higher toward the end portion, it is adequate to make type group velocity of the electric field smaller and smaller toward the end portion. Thereby the accelerating voltage of the superconductive accelerating cavity can be improved or the length of the accelerating cavity can be shortened.

Abstract: PURPOSE:To expand the variable range of an oscillating frequency by adding a variable impedance element to a feedback circuit. CONSTITUTION:A feedback capacitance in a conventional oscillating circuit is replaced by a series circuit comprising a capacitor 51 and a varactor diode 52, and a feedback element impedance 2 and the capacitance of a capacitor 51 are selected so as to satisfy the oscillating conditions at a high oscillating frequency. Since the capacitance of a varactor diode 52 is increased at a low oscillating frequency and a series feedback element circuit whose impedance is decreased as the frequency is lower is included to an input impedance viewed from a base of a transistor 1, the frequency variable range of the series resonance circuit including the varactor diode 4 and the main resonance line 5 is expanded. Furthermore, the value of the relative feedback amount is ensured to be a value equal to or more than that at a high oscillating frequency even if the oscillating frequency is low by selecting the capacitance change rate of the varactor diode 52 and the capacitance of the capacitor 51 so that the feedback impedance at the low oscillating frequency is not lowered in comparison with the high oscillating frequency.

Abstract: PROBLEM TO BE SOLVED: To reduce an electrostatic capacity between a reflection plate and a case and to reduce leak current due to capacitive coupling by providing a part adjacent to a lamp in a case with a bulge part or a slit. SOLUTION: Electrostatic capacitance between a reflection plate 10 and a metallic cases 12, 13, 14 is determined by capacitance of an overlaid part of the reflection plate 10 under a light transmission plate at the shortest distance therefrom on the metallic case 12. Therefore, the capacitance between the reflection plate 10 and the metallic case 12 is reduced by forming a bulge part 18 going off from a lamp 9 over the metallic part 12 of the overlaid part and providing an air gap space with a holding-use insulating sheet 11 left. The effect similar to the case with the air gap is attainable even when the capacitance between the reflection plate 10 and the metallic case 12 is reduced by providing the overlaid part of the reflection plate 10 over the metallic case 12 with an opening of a slit and reducing an area of a part equivalent to the capacitance electrode.

Abstract: PROBLEM TO BE SOLVED: To efficiently form a projection and to improve material soundness by irradiating the outside surface of a metal tube held horizontally with an electronic beam to heat and melt the irradiated part up to the inner surface side, swelling the molten metal in a projecting shape in the inner surface side and solidifying it. SOLUTION: A metal tube 1 is horizontally held, an electronic beam gun G is directed to the outside surface of the metal tube 1 from the upward of the metal tube 1. The outside surface of the metal tube 1 is irradiated with the electronic beam B from the electronic beam gun G, and the irradiated part of the metal tube 1 is heated and molten up to the inner surface side. The molten metal in the molten part M is subjected to a suspending condition swelling to the inside space from the inside surface I3 of the tube in a projecting shape due to the balance between the self-weight and the surface tension, and solidified in that condition to form the projection 2.  Therefore, the time required for working is largely reduced compared with a welding method by cladding and moreover the operation for inserting a welding torch into the tube is unnecessitated, whereby this method is applied even to the tube having an extremely small diameter regardless of the size of the tube.
