Title: Method of preventing intrusion of atmospheric air into heat-insulating container
Inventor: HONGOU AKIRA
IPC: F17C13/02
Filed: 1982-03-26
Abstract: PURPOSE:To prevent icing and frosting on the wall surface of a heat-insulating container and on varius surfaces of a discharging apparatus, by preventing intrusion of atmospheric air into the container when it is empty and not in use by charging a dry gas into the same. CONSTITUTION:In order to prevent the intrusion of atmospheric air into a heat- insulating container 4 when it is empty, vaporized nitrogen gas on the surface of liquid nitrogen in a supply container 1 is supplied via a conduit 8 and a valve 9 into the heat-insulating container 4. The nitrogen gas thus supplied to the container 4 is discharged to the atmosphere via a gas exhaust pipe 10 while filling the inner space of the container 4 with nitrogen gas, and liquid nitrogen left in the insulating container 4 is also discharged completely to the outside, so that the inner space of the container 4 is completely filled with nitrogen gas. Since the nitrogen gas produced by vaporization of liquid nitrogen contains no moisture, the inner space of the insulating container 4 can be kept dry.

Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a reasonable stator through easier connection works, by arranging a conductor provided with insulation coating to a terminal plate having a groove, and then connecting the conductor to a terminal of the in-phase coil winding. SOLUTION: A stator is divided to 12 pieces of pole tooth 1 and it is combined after a coil winding 2 is wound to each pole tooth 1. The stator corresponds to the 3-phase structure of U, V and W phases. To the twelve pole teeth 1, the coil windings 2 corresponding to U, V, W phases are arranged in the circumference direction with equal interval of four teeth in every other two teeth. It is enough that three kinds of conductors 3a, 4a, 5a and the common conductor 6 are, for example, bent along the groove 7a using the insulator- covered copper wire obtained by forming a multi-layer of polyimide or polyester as the insulator of the copper wire. As the connecting method, a pressure connecting method using a pressure depositing terminal, fusing method by the resistive welding and soldering or blazing, etc., may be employed. Thereby, connection work can be simplified.

Title: Emission of electron and its device
Inventor: SHIMODA ISAMU
IPC: H01J1/304
Filed: 1987-03-04
Abstract: PURPOSE:To make emission of electrons possible for which wiring connection is not required and mounting degree is high by supplying after electron emitting action, electric charge of an electron emitting electrode lost by emission of electrons at the time of the emitting action. CONSTITUTION:At the time of action of electron emission, positive charge is accumulated on an electron emitting electrode 4, and intensity of magnetic field is weakened, so emission quantity of electrons is reduced, and finally emission of electrons stops. Then, by using a switching means 10, a voltage of the opposite direction is applied between a pulling electrode 7 and a voltage applying electrode 1, while potential of a voltage applied to a matter subject to irradiation 5 is set at 0V by means of a switching means 11, so electrons are emitted from the pulling electrode 7 to the side of the electron emitting electrode 4. Emitted electrodes are connected with positive electric charge accumulated on the electron emitting electrode 4 to reduce and eliminate the accumulated positive electric charge, where the electron emitting electrode 4 is ready for emission of electrons. Thus it is possible to let an electron emitting electrode provided solely on the surface of insulation perform emission of electrons. Electron emission is to be performed by two or more electron emitting electrodes.

Abstract: PURPOSE:To suppress the fluctuation of an inverter input voltage and thus to obtain a power unit minimized for voltage fluctuation by arranging such that a control angle of a rectifier through which to supply power to inverter according to a load operation can be changed according to the control angle at no-load operation. CONSTITUTION:An alternating current from power supply is converted through a rectifier 1, a smoothing circuit 2, an inverter 3, a transformer 4, a rectifier 5 and supplied to a load 6 like X-ray tube; a control angle of the rectifier 1 is controlled by a gate circuit 8 according to a difference between an output voltage VF of the circuit 2 and a set point VP. Where there is working an X-ray tube voltage impression command signal CVS, the inverter 3 is kept operating, therefore a constant voltage controlling circuit 10 issues a control signal to change the control angle of the rectifier 1 from a value necessary for peak charging of the filter 2 to a value necessary for mean value current in accordance with a signal from a control command generating circuit 20. Where there is no signal CVS working, the circuit 10 issues a signal necessary for peak charging.

Abstract: PURPOSE:To secure 1/100sec precision securely and to prevent a shutter from being distorted by providing a shutter part which controls the passing of light by the combination of crystal which has its plane of polarization rotated according to the on/off state of a voltage and a polarizing plate. CONSTITUTION:The shutter part 4 is an electro-optic shutter and consists of the crystal 4a of KDP (heavy potassium phosphate) and the polarizing plate 4b. The KDP causes birefringence by being impressed with a specific voltage to rotate an incident linear polarized wave by 90 deg., so polarizing plates in the same direction are arranged in front of and behind the KDP and the voltage impressed to the KDP is turned on and off to control the passing of light. This shutter part 4 is made circular to the same diameter with a lens barrel and a screw 4c for coupling a screw 7a for filter fitting provided to the lens barrel 7 is provided on one surface, so that the shutter part is attachable and detachable. Consequently, the opening/closing time of the shutter is not affected by wind and the whole visual field is opened and closed instantaneously, so no influence of shutter distortion appears in a photographic image of a meteor.
