  • Dielectric barrier discharge lamp and lamp unit
    Patent number: 8686639
    Abstract: A dielectric barrier discharge lamp is described, including a discharge tube having an elongated shape and enclosing a discharge gas therein, and a pair of electrodes. A portion of an outer peripheral surface of the discharge tube in a longitudinal direction of the discharge tube is defined as a light extraction area for extracting light induced in the discharge tube to an outside. The pair of the electrodes are placed on the outer peripheral surface such that the light extraction area is positioned between the pair of the electrodes in a peripheral direction of the outer peripheral surface of the discharge tube.
    Type: Grant

  • Immersion nozzle for continuous casting
    Patent number: 4949778
    Abstract: In an immersion nozzle for continuous casting, at least one portion of reduced a sectional area of passage for molten metal is formed near to the bottom of the nozzle and plural discharge ports symmetrically arranged with respect to the axis of the nozzle are arranged above and below the reduced sectional area portion in the longitudinal direction of the nozzle. Further, molten metal is continuously cast by using the above immersion nozzle together with a static magnetic field.
