    摘要: A pivoting device especially useful in aircraft passenger cabins that can pivot a monitor between stowed and open positions, the pivoting device including a forward/reverse rotatable driving motor. An electromagnetic brake holds the monitor in stowed and opened positions A power unit powers the motor and the electromagnetic brake. A controller controls the pivoting movement of the monitor. The power unit includes a rectifier circuit that transforms AC to a DC, a step-up circuit that steps up the transformed voltage, a voltage regulator that adjusts the transformed voltage to a prescribed DC voltage, and a retraction power retention circuit including a capacitor. When no source voltage is detected while the monitor is in its opened state, the capacitor supplies the power to a voltage regulator of the power circuit, deactivates the electromagnetic brake and reverse rotates the motor to drive the monitor to its stowed position.

    摘要: A method for manufacturing a silicon single crystal. In this method, silicon material melting is performed in a furnace having an internal pressure between 60 and 400 mbar. The subsequent single crystal pulling is performed in a furnace having an internal pressure which is lower than the pressure when the silicon material is molten, but not exceeding 95 mbar. This method prevents production of a defective single crystal which results from the formation of pinholes, prevents dislocation of the single crystal which results from bubbles and impurities present in silicon melting solution, and prevents dislocation of the single crystal which results from evaporation of the SiO.
