Title: Superconducting rotary electric machine
Inventor: YOSHIMURA HIDETO
IPC: H02K55/04
Filed: 1987-07-24
Abstract: PURPOSE:To obtain a superconducting rotary electric machine easy for cooling a rotor, by feeding a cooling medium to the rotor from a nozzle set on the periphery of the rotor. CONSTITUTION:A piping 40 for distributing liquid N2 from a header 29 to a nozzle 28 is embedded in the whole area of a heat insulating layer 27 confronted with a field coil 38 for example. A rotor 21 is cooled by feeding the liquid N2 to the rotor 21 from the nozzle 28 set on the periphery of the rotor 21, between the rotor 21 and a stator 25. The liquid N2 is sprayed on the surface section of the rotating rotor 21 through the nozzle 28 and is fed to, and the rotor 21 is directly cooled by the vaporizing latent heat of the liquid N2. The vaporized N2 is collected in a vapor reservoir 33, and is liquefied by a liquefying device 35, and is turned into the liquid N2, and is fed to a liquid receiver 31. The liquid N2 received in the liquid reservoir 31 is pressure-fed to the header 29 by a pump 32, and is sprayed on the surface section of the rotor 21 again. By this cooling means, the rotor 21 is cooled through the periphery almost at the same time, and so the rotor can be comparatively uniformly cooled.

Abstract: PURPOSE:To obtain the titled memory, having a memory element with which write-in, read-out and erasing operations can be performed and which has little deterioration in memory elements, by a method wherein the quantity of charge carrier injected through an insulating film is controlled by increasing or decreasing the substrate potential. CONSTITUTION:In the N-channel element, an electron and a paired hole are ionizationally induced in the vicinity of a drain 82 by the flow 8a of the electron travelling on a channel 83, but the most part of a hole runs into a substrate 81 as a substrate current. At this time, if the channel impurity density is high, a paired electron and a hole are induced in the surface depletion layer by the secondary ionization using the hole which constitutes the substrate current as a seed. The electron generated by the secondary ionization is accelerated toward the surface, but a part of which becomes to have the energy enough to go through an insulating film barrier, and injected into an insulating film 84. The above-mentioned injection of electron is generated only when a proper degree of positive potential is applied to the drain and the gate and when the substrate is maintained in the proper degree of negative potential.

IPC: G03G15/14
Filed: 1989-07-18
Abstract: PURPOSE:To obtain sufficient printing quality even immediately after starting printing by rotating a transfer plate through a link mechanism by driving a DC motor. CONSTITUTION:The transfer plate 2 is set to be separated from a photosensitive drum 1 by the link 3 driven by the DC motor 4 in a state other than a printing action state so that a recording paper 6 may not come into contact with the photosensitive drum 1. When a toner image approaches a transfer position, a BD tractor 8 is operated to control the recording paper 6 to be at a speed equal to that of the photosensitive drum 1. At the same time, the transfer plate 2 is actuated so as to make the photosensitive drum 1 and the recording paper 6 contact with each other. By impressing forward voltage, the DC motor 4 starts rotation in uniform acceleration, and by impressing reverse voltage, the motor 4 begins the decelerating rotation in the uniform acceleration and stops, then the transfer plate 2 performs the rotation in the larger acceleration through the link arm 3. While the action of the link mechanism 3 is accelerated, shock at the time of completing the action is reduced, and the printing quality immediately after starting printing is improved.
