摘要： A vacuum interrupter comprises a pair of opposed conductor rods extending exteriorlly of a vacuum vessel, a pair of main electrodes mounted to ends of the paired conductor rods and separable from each other, and coil electrodes which induce axial magnetic flux acting on arc produced when one main electrode separates from the other main electrode. The coil electrode includes a first arm section connected to the conductor rod and passing the current coming from one portion of the conductor rod radially thereof, a branching section for branching the current from the first arm section in reverse directions, and a second arm section for passing the branched currents until they are totalized again at the other portion of the conductor rod separated from the one portion by a spacer interposed between the first and second arm sections, whereby magnetic flux induced by the branched currents is cancelled out at the conductor rod, preventing the generation of eddy current in the conductor rod.

摘要： A vacuum interrupter comprises a pair of electrodes separably arranged within a vacuum vessel and mounted on conductor rods respectively. Each of the electrodes includes a coil electrode and a main electrode. The coil electrode is adapted to branch the current in the conductor rod in different radial directions with respect to the conductor rod for generating magnetic fields in axial direction of said conductor rod in such a manner as to offset each other at points near to the conductor rod. The main electrode is electrically connected with the coil electrode for carrying an arc. The main electrode includes a plurality of first current paths for passing the current in different radial directions, a plurality of second current paths for passing the current from the coil electrode to the first current paths, and a plurality of third current paths for passing the current therein in opposite directions to the current in the second current paths. Magnetic fields are generated in the main electrode in the same axial direction as those generated in the coil electrode, with the result that the arc is extinguished quicker when compared with the case where only one of the main and coil electrodes generates the axial magnetic field, thus improving the current-interrupting performance.

摘要： The invention is to provide a gas laser in which a discharge tube of a double-tube construction comprising a inner tube and an outer tube of a relatively large diameter is employed, a tubular discharge space filled with a gas mixture is formed between the inner tube and the outer tube, a gas mixture cooling passage is formed within the discharge space, and a pair of mirror groups are disposed at both ends of the discharge space, each mirror group comprising a plurality of mirrors arranged in the circumferential direction. The respective mirrors are arranged in such a manner that a laser beam is reflected by the mirrors to go and return in the discharge space several times and each path of the laser beam between the corresponding two mirrors obliquely intersects the central axis of the discharge space. Thus, it is possible to obtain a laser beam in single mode with a single discharge tube without the need of enlarging a length of the tube and also to reduce a pressure loss of the gas mixture within the discharge space.

摘要： A gas laser has an electrode of improved construction. The electrode, for example a cathode, comprises an inner cathode and at least an outer cathode spaced from the inner cathode and disposed on the side thereof away from to an anode. Each of the cathodes has a central hole from which glow discharge is formed, and the outer cathode further has a plurality of through-holes around the central hole. A gas medium flowing in a discharge tube passes through the central hole of the inner cathode via the central hole and through-holes of the outer cathode. The gas medium forcedly enters the glow discharge from the inner cathode thereby to cause it expand and a part of the gas medium having passed through the through-holes of the outer cathode squeeze the glow discharge from the outer cathode so that the glow discharge can enter the glow discharge from the inner cathode. Therefore, the current density of the glow discharge in the discharge tube is made information.
