  • Patent number: 10170269
    Abstract: A magnetron includes an anode cylinder extending in a cylindrical shape along a central axis and a plurality of plate-like vanes at least each one end of which is fixed to the anode cylinder, extending from an inner face of the anode cylinder toward the central axis, in which the anode cylinder includes refrigerant flow paths for directly applying a refrigerant to the plate-like vanes. The refrigerant flow paths 111 are openings formed so that end surfaces (joint end faces of the plate-like vanes) of the plate-like vanes are exposed, which allow the refrigerant to directly contact the plate-like vanes.
    Type: Grant

  • Patent number: 10090130
    Abstract: Provided are a magnetron whose resonance frequency is easily adjusted and a method of adjusting a resonance frequency of the magnetron. A magnetron includes an anode cylinder extending in a cylindrical shape along a central axis, a plurality of tabular vanes each having at least one end fixed to the anode cylinder and extending toward the central axis from an inner surface of the anode cylinder, and pressure-equalizing rings disposed coaxially with respect to the central axis of the anode cylinder, and alternately electrically connecting the tabular vanes to each other. The tabular vanes have protrusions facing the pressure-equalizing rings in an axial direction of the anode cylinder, and notches serving as base points for deforming the protrusions toward the pressure-equalizing rings sides or opposite sides thereto.

  • Patent number: 7852005
    Abstract: The invention relates to a fluorescent lamp with an external electrode used as a backlight of a liquid crystal display device or others. To reduce invalid parts of the backlight, the length in an axial direction of an external electrode of the fluorescent lamp is required to be reduced. Therefore, a concave portion is provided to the end of the fluorescent lamp with an external electrode, and by forming the external electrode in the concave portion, the total area of the external electrodes is secured. Even if the length in the axial direction of the external electrode is short, discharge is stabilized. Graphite is used for the external electrode; however, graphite in which a water glass component is increased to enhance its mechanical strength is used.

  • Patent number: 7800712
    Abstract: A cold cathode fluorescent lamp includes a tube having an inner surface coated with a fluorescent film and tubular discharge electrodes disposed at both inner ends of the tube. Each discharge electrode has an opening facing a discharge area and includes a projection in the opening, the area of the projection being reduced by electric discharge.
