  • Patent number: 7977696
    Abstract: A light emitting element mounting substrate that enables a high quality light emitting element package to be readily manufactured with minimal variations in the chromaticity when manufacturing a white LED, a light emitting element package that employs the substrate, and a display device and illumination device that employs this package, are provided. In the light emitting element mounting substrate, at least a light emitting element mounting portion of a surface of a core metal is coated with a fluorescent enamel layer that consists of a fluorescent material-containing glass. In the light emitting element package, a light emitting element is mounted on the light emitting element mounting substrate, and the light emitting element is sealed with a transparent sealing resin.

  • Patent number: 5192940
    Abstract: A flat resistance for a blower control unit of an automobile air conditioner, and a blower control unit using the same. The flat resistance includes: a porcelain enameled metallic substrate including a flat head portion, having an edge and one surface, and parallel terminal supporting portions projecting outwardly from the edge of the head; a resistance circuit printed on the one surface of the head portion, the resistance circuit including a plurality of resistances electrically connected in series; a temperature fuse, interposed in the resistance circuit, for being tripped to break the resistance circuit when the porcelain enameled metallic substrate becomes overheated; and terminals, printed on both the head portion and the terminal supporting portions, each terminal being connected to one end of a corresponding one of the resistances.
