Title: Controller for ac electric car
Inventor: ISHIKAWA TOMOAKI
IPC: H02P27/06
Filed: 1987-01-26
Abstract: PURPOSE:To prevent the flow of rush current into a capacitor when power source is restored by operating an inverter in a power regenerative mode when the interruption of the power source occurs during power running. CONSTITUTION:When the voltage of secondary winding of a transformer TR has reduced to a predetermined value, a voltage comparing circuit 1 outputs a line service interruption detecting signal. According to this output of the signal, a PWM converter circuit CONV and an inverter circuit INV are stopped. Further, the voltage comparing circuit 2 outputs a signal of 'H' level when the voltage of a capacitor CO has been reduced to an allowable value. Accordingly, a flip-flop circuit FC is set and an inverter power regenerative braking command is outputted to an inverter control circuit INC. In this case, the voltage comparing circuit 3 detects overvoltage so that the capacitor Co is not charged excessively. When voltage is impressed again, the line service interruption detecting signal of the voltage comparing circuit 1 is cancelled.

Filed: 1990-01-23
Abstract: PURPOSE:To prevent faulty electrostatic charging in the case of forming an electrostatic latent image on an electrostatic recording paper at least every three primary colors from occurring and to obtain a high-definition color image by providing a temporary fixing means and a normal fixing means as a fixing means. CONSTITUTION:The electrostatic recording paper A where the electrostatic latent image for black is formed by an electrostatic latent image device 10a is fed to a developing device 20a, and the image is developed by attracting the toner for black. When it is fed to the temporary fixing device 30a, a flash lamp 31a is lighted to heat the toner and temporarily fix the image. The respective toner images of yellow, cyanogen and magenta formed by the electrostatic latent image devices 10b-10d are developed by the developing devices 20b-20d and tentatively fixed in the same manner. Finally, the normal fixing device 40 normally fixes the toner by allowing a pair of heated rolls 41 in press-contact with the recording paper A. Since the toner image is temporarily fixed on the recording paper with non-contact, the latent images of the respective colors are surely formed without causing the faulty electrostatic charging by crushing a spacer agent.

IPC: G11B15/70
Filed: 1986-01-28
Abstract: PURPOSE:To always produce good slave tapes by storing a mother tape in such cartridge that most of magnetic faces are not brought into contact with one another. CONSTITUTION:A bias magnetic field is generated by the magnetic heads 9 and 10 of a pair of rolls 7 and 8, and the recorded contents of a mother tape 2 are transferred magnetically to a slave tape 1. Since the mother tape 2 is endless, they are transferred magnetically continuously to the slave tape 1 which is several - several hundreds times as long as the mother tape 2. Since the master tape is stored in a cartridge 15, the quantity of magnetism is not reduced by mutual contacting among magnetic faces, and the recorded contents are always well transferred magnetically.

Title: Method of producing artificial snow
Inventor: EBINUMA TAKAO
IPC: F25C3/04
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To make artificial snow grow in a floating state by providing a high- voltage pole in a space where supercooled water droplets or ice particles float, forming an electric field with the aid of the high-voltage pole and dielectrically polarizing the supercooled water droplets or the ice particles to merge and grow them into artificial snow. SOLUTION: Water droplets are fed from a water droplet feeder 20 into a space which is air-conditioned to a temperature below the freezing point. The water droplets thus fed are converted into supercooled water droplets or into ice particles 2 by exchanging heat with cold air. On the other hand, air is ejected in the arrow direction 23 shown in the Figure from a compressed air source 21 into the space through a porous plate 22. The supercooled water droplets or the ice particles 2 move in the arrow direction 24 in a floating state by the ejected air, and, while moving, they are merged with one another with the effect of dielectric polarization excited by a high-voltage pole 1 and grow into artificial snow 26 having a shape similar to a resinous crystal. This artificial snow 26 is moved to a snowfall supply area 27 by a stream of air and falls in the area.

Title: Fixing device
Inventor: ONISHI TAIZO
IPC: G03G15/20
Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a fixing device capable of prolonging the service life of a heating roller by suppressing the damage of a roller caused by a press- contact member used in a press-contact state with the heating roller, such as a separating pawl and a temperature detecting element in a fixing device provided with the heating roller heated to heat-fix an image on a recording material holding an unfixed image. SOLUTION: A thermistor 31 is supported to come into press-contact with the heating roller by a supporting member 32 having bimetallic structure. The supporting member 32 is constituted in such a manner that two kinds of metallic plates 321 and 322 whose thermal expansion coefficients are different are stuck to each other and the thermal expansion coefficient of the metallic plate 321 is smaller. When ambient temp. rises, the supporting member 32 is curved to push the thermistor 31 toward the heating roller 1. When the ambient temp. is low, the press-contact force of the thermistor becomes small.
