  • Patent number: 6411077
    Abstract: An optical-voltage sensor having a simple structure and being capable of being formed by directly laminating highly sensitive electro-optical elements is disclosed. The optical-voltage sensor includes a light source 1, a polarizer 2, a ¼ wavelength plate 3, an analyzer 5, and an O/E converting portion. Two electro-optical elements 4a, 4b are arranged adjacent to each other along a light transmitting direction between the ¼ wavelength plate 3 and analyzer 5. Transparent electrodes 7 are attached to front and back surfaces of each of the electro-optical elements 4a, 4b, and voltages having a magnitude equal to one another and a polarity opposite to one another are applied to the electro-optical elements 4a, 4b from a power supply 8a and a power supply 8b, respectively.

  • Patent number: 4782362
    Abstract: The timing signal generated by the paper sending-out roller or the paper detector outputs a signal with synchronously the paper sending-out cycle. The flash lamp photoflashes with synchronously the output signal. The photoflash is generated in accordance with length of carrying direction of the paper. The paper sending-out roller sends out one of a plurality of the papers in accordance with a predetermined timing signal, and the flash lamp photoflashes at a predetermined number of times and stops the flashlight at a predetermined time in accordance with the predetermined timing signal as an index. The paper detector is installed at a position close to the paper carrying apparatus line from the flash fusing apparatus, and a delay circuit is provided so as to delay the detection output of the paper detector with a predetermined time. No photoflash irradiates the gap between a precede paper and a next paper at the continue printing the a plurality of cut sheets.

  • Patent number: 4767931
    Abstract: A thin film manufacturing and processing apparatus by using an ion beam comprises a plasma producing vessel for producing therein a plasma by ionizing a neutral gas, an electrode assembly for extracting ions in the form of an ion beam from the plasma, a vacuum container accomodating therein a target to be worked through irradiation of the ion beam, and permanent magnets disposed on the outer periphery of the plasma generating vessel which is formed of a nonmagnetic material and serves as an anode electrode. An ion beam of high uniformity and a large diameter can be obtained to allow manufacture and processing of large scale magnetic thin films and semiconductors with high precision.

  • Patent number: 4571570
    Abstract: A winding for a static induction apparatus such as a transformer, a reactor and the like comprises a plurality of interleaved coils each formed by winding an electrically insulated strand conductor in a radial spiral. The coils are stacked axially and electrically connected in series between a line terminal and another terminal such as a neutral terminal. The winding is divided into a plurality of blocks each including a plurality of ones of the interleaved coils. The number of turns of each coil belonging to the block on the other terminal side is decreased as compared with that of each coil belonging to the block located closer to the line terminal, to thereby reduce the series electrostatic capacitance of the coils stepwise from one to another block starting from the one located on the line terminal side. The distribution constant is thus decreased. Favorable surge withstanding characteristics are attained, reliable insulation is assured and the winding can be realized in a reduced size.
