摘要： A DC circuit breaker of the type using a blown arc-extinguishing gas is disclosed which allows for reliable fast interruption of DC currents through the provision of arc extension current paths. The extension current paths are relatively long and are bent after the incidence of the arc-extinguishing gas on the arc. The arc is formed to extend for a long distance in a loop configuration. An auxiliary electrode short-circuits the extended arc with one auxiliary electrode being provided for each extension current path.

摘要： A current interruption apparatus comprises a series-connected combination of at least one vacuum interrupter and at least one gas-blast interrupter. Each vacuum interrupter is coupled in parallel with a non-linear resistor, while each gas-blast interrupter is coupled in parallel with a capacitor. During the initial period of the recovery voltage developed upon current interruption, most of the recovery voltage is applied to the vacuum interrupter. After the instant at which the non-linear resistor represents its constant voltage characteristics, the SF.sub.6 gas-blast interrupter will take the largest portion of the entire voltage increased thereafter.

摘要： Circuit interrupting apparatus for interrupting large direct currents comprising a plurality of parallelly connected branch circuits each including a circuit breaker and a saturable reactor connected in series therewith, and a commutating circuit including a capacitor. When opening the circuit breakers the commutating circuit is connected across the branch circuits to pass commutating current in the direction opposite to the normal load current. When the current decreases below a predetermined value, the saturable reactors desaturate to efficiently interrupt the load current.

摘要： A transverse type gas laser oscillator includes a receptacle for containing a gas as a laser medium, a pair of electrodes disposed to be parallel to each other on opposite sides of the receptacle so that an electric field is established for generation of AC discharge when a high-frequency voltage is applied to them, and a pair of permanent magnets disposed so as to form a magnetic field intersecting a direction of the electric field established between the electrodes, or a pair of coils excited by a DC voltage. Consequently, ionization of the gas excited by the electric field is increased by the magnetic field.
