    摘要: A method of injection molding a styrene resin or a composition thereof, which includes injection molding a molten molding resin material of a styrene-conjugated diene block copolymer containing 50 to 90% by weight of a styrene polymer or a molten molding resin material of a resin composition comprising 50% by weight or more of the styrene-conjugated diene block copolymer and 50% by weight or less of a styrene resin other than the styrene-conjugated diene block copolymer, wherein the molten resin is injected and filled into a mold with a wall surface temperature at core and cavity portions within the mold being made 110.degree. to 180.degree. C., and the molded product is demolded when the wall surface temperature of the core and cavity portions is lowered to the glass transition temperature or lower of the styrene polymer moiety in the block copolymer. The obtained molded product has a high impact resistance.

    摘要: A gas laser generator comprises a frame, a gas channel through which a gas flows, a mirror for obtaining a laser beam, defining a resonant cavity, an anode electrode and at least two first and at least two second cathode electrodes arranged in the lower and the upper portions of the resonant cavity, respectively, and a power source, in which a first voltage of a first electric field between the first cathode electrodes connected to the power source through a first ballast resistance and the anode electrode and a second voltage of a second electric field between the second cathode electrodes connected to the power source through a second ballast resistance and the anode electrode are so determined that the former is smaller than the latter so that the current flowing in the first electric field may be substantially equal to the current flowing in the second electric field during the electric discharges between the electrodes.

    摘要: An AC exciter and a main AC generator are mounted on a common rotating shaft of an engine, and a power rectifier and a power inverter are connected in series to the output of the main AC generator. In starter mode, an external AC power source is connected by a switch to the input of the power rectifier, and the output of the power inverter is applied to an armature winding of the main AC generator to drive it as a nocommutator motor to start the engine. A permanent magnet AC generator is also mounted on the common shaft of the engine to provide DC excitation to the AC exciter after converting the output of the permanent magnet AC generator into DC current, and the output of the permanent magnet AC generator is further utilized to detect the rotational speed of the engine to control the switch.
