Title: Gas leakage detector of opening and closing device for insulating gas
Inventor: OOSHIMA MASAHIDE
IPC: G01R31/333
Filed: 1982-03-24
Abstract: PURPOSE:To monitor leakage with high accuracy, by comparing the output signals of  pressure transducers which convert the gaseous pressures in an opening and closing  device for insulating gas to electric signals. CONSTITUTION:Pressure transducers 8u-8w are mounted respectively to circuit breakers 1u-1w of a (u) phase, (v) phase and (w) phase respectively consisting of 3 phases,  and the equil. AC voltages of the three phases; (u) phase, (v) phase and (w) phase are  supplied thereto from an electric power source 9. The outputs of the transducers 8u- 8w are the voltages of the (u) phase, (v) phase and (w) phase proportional to respective  gaseous pressures and are inputted collectively to a galvanometer 10. Gases are packed  in the breaker bodies 2u, 2v, 2w through valves 5u, 5v, 5w so as to attain rated outputs  in terms of 20 deg.C and the gaseous pressures are balanced to prevent the flow of electric  currents to the galvanometer 10. When gas leakage arises in the breaker bodies, the outputs of the transducers decrease, and the current having a 180 deg. phase difference from the voltage of the power source 9 flows to the galvanometer 10. Thus, the presence or  absence of the gas leakage is detected from the presence or absence of the current flowing in the galvanometer 10, and the phase having the gas leakage is discriminated  from the direction of the vector of the current.

Abstract: PURPOSE:To make the container small in size, simple in structure and to make trays easy to operation of storing and pulling by enabling each tray to move from a storing position at which the information recording face of a disk placed on a magazine is concealed perfectly to a projected position at which the face is perfectly exposed, and controlling the projected position. CONSTITUTION:For instance, when a tray 1D is pulled out, upper and lower steel balls 9 positioned at a long hole 10, are pushed apart mutually in vertical direction by the peripheral part 11. Consequently, the steel balls 9 move between trays 1A, 1B, 1C, 1E, 1F and a partition plate 30. As the movement in the direction of returning is obstructed by the peripheral part of the tray 1D, trays 1A, 1B, 1C, 1E, 1F are locked to make movement impossible. When the tray 1D is pushed back in original direction after placing the disk 2 on the placing section 3 of pulled out tray 1D, the guide section 12 of the tray 1D is housed in the magazine 18 guided by the partition groove 24 of the magazine structure 19.
