    Abstract: An apparatus for use in a gas laser having internal mirrors comprising an electric discharge tube, a cathode chamber operatively connected with one end of the electric discharge tube, an anode chamber operatively connected to the other end of the discharge tube, and two reflecting mirrors one mounted on the wall of the cathode chamber and the other on the wall of the anode chamber and aligned opposite one another in the direction of the axis of the electric discharge tube. An anode means forms the wall of the anode chamber and surrounds the other end of the electric discharge tube and varies the length of the anode chamber in the axial direction. Means are provided for varying the length of the anode means.

    Abstract: A solid state inductive device comprises either a sandwich of a N-type and a P-type semiconductor with an insulating layer therebetween, or a semiconductor and a plurality of metal strips with a dielectric layer therebetween. A current electrode is connected to the opposite ends of the semiconductor and interconnect the semiconductors in the first embodiment, the metal strips being angular to the direction of the electrodes in the second embodiment. The device forms an inductive reactance between the electrodes upon application of a magnetic field in an angular direction to a side of the device.
