Title: Detection of insulation deterioration of electric power system
Inventor: KANAI MINORU
IPC: H02H3/17
Filed: 1990-04-18
Abstract: PURPOSE:To reduce an insulation deterioration and the effects of its residual amount in the section and of a noise, and to detect them with high sensitivity by injecting a voltage signal into a 3-phase bus line and calculating electrostatic capacitances to the ground for each phase from the detected values in terms of injection frequencies of a zero-phase-sequence current and voltages for each phase. CONSTITUTION:Sine waves having three phases and three kinds of frequency components are oscillated from oscillators 23R, 23S, 23T shown in the figure. These signals are continuously injected through insulation transformers 22R, 22S, 22T and high voltage coupling capacitors 21R, 21S, 21T. For three kinds of frequency components at this time, the frequencies other than the power source frequency and its harmonic frequencies are selected to distinguish the signal for harmonic frequencies of the power source frequency. The amount of injection voltage is selected to the almost equal values for all three phases within the range unaffecting the system. As the result of abovementioned voltage injection, the zero-phase-sequence current and voltages for each phase in terms of the injection frequencies can be detected at each point along a distribution line.

IPC: B01L1/00
Filed: 1989-04-21
Abstract: PURPOSE:To lower a quantity of airflow and at the same time to prevent inter-action pollution between a chemical bath and a vaporizing bowl by installing a drawing hood which is connected to a gas discharging system in the way of covering the upper surface of the chemical bath and opening a drawing outlet which faces to the upper surface of the chemical bath in the inside of the drawing hood. CONSTITUTION:When a gas supplying fan 4 and a gas discharging fan 7 are operated, a downward airflow A reaches the upper surface of a chemical bath 2, becomes a high speed drawn airflow, flows to a drawing outlet 14 of a drawing hood 13 opened in the periphery of the upper surface, and is discharged outside through a gas discharge tunnel 12 and a gas discharge duct 6. A part of the downward airflow A is discharged outside through a gas discharging outlet 5 opened in the back of a chamber 1. When a chemical 22 contained in the chemical bath 2 is heated by a heater 2a, a vapor of the chemical is generated but it is almost completely suppressed from diffusion and scattering to a chamber space 1a by the downward airflow A and drawn to the drawing outlet 14 by induction function of the high speed drawn airflow C immediately after vaporized at the upper surface of the chemical bath 2 and then the vapor is discharged outside.

Title: Current synthesizer
Inventor: OKADA ISAMU
IPC: H02H3/02
Filed: 1980-07-25
Abstract: PURPOSE:To obtain a device which synthesizes a current precisely without any synthesis error due to energizing impedance like a current transformer, by using a polarizing rotary element and by utilizing light as a medium. CONSTITUTION:Currents I1 and I2 are flowed to energizing coils 22a and 22b of a polarizing rotary device 20 to establish a magnetic field in the axial direction of a magnetic optical rotatory body 21. The plane of polarization of the optical rotatory body 21 turns in proportion to the intensity of the magnetic field according to the Faraday effect. A synthesized current regenerating device 40 is equipped with an analyzing element 44 and unless the plane of polarization of light polarized by a polarizing element 32 is turned, no light passes through the element 44. As the plane of polarization is turned by a rotary device 20, the light reaches a photoelectric element 45 via the analyzing element 44 to generate electromotive force. It is amplified to obtain a current I3 flowing to a closed circuit 48 including an energizing coil 42 and a load 47. This current I3 produces a magnetic field around a magnetic optical rotatory body 41 in the device 40 to turn the plane of polarization in the opposite direction to the device 20. In this case, I3=I1+I2 holds for adequate coefficients.
