    摘要: A switchgear comprises in a housing containing an arc extinguishing gas, a pair of separable contacts defining therebetween an arcing region in which an electric arc is generated when the contacts are separated. A cylindrical wall and an insulating nozzle are provided for defining a gas storage chamber around the stationary contact communicated with the arcing region for storing the arc extinguishing gas increased in pressure by heat from the arc. The insulating nozzle defines an opening through which the movable contact movably extends and through which the pressurized arc extinguishing gas flows. Around the arcing region a magnet is disposed for generating a magnetic field in the opening of the gas storage chamber for rotating and elongating the electric arc generated in the arcing region upon current interruption.

    摘要: A holder in which a bubble cassette housing a bubble memory device is inserted. The contacts of the holder contact the contacts of the cassette when the cassette is inserted into the holder, so that current can flow into the bubble memory device. The holder contains a detector for detecting the insertion and withdrawal of the cassette. A circuit controls the current introduced into the magnetic-bubble memory device so that the current is introduced after the contacts of the cassette and the contacts of the holder are connected and is interrupted before the contacts of the cassette and the contacts of the holder are disconnected.
