  • Patent number: 8311777
    Abstract: An oven wall three-dimensional profile data (701) representing concave and convex amounts on all over oven walls (14R, 14L) at a right side and left side of a coking chamber (11) is generated by using image signals obtained by a wall surface observation apparatus (200). A resistance index “k” in which a resistance received by pushed coke (15) resulting from a rising gradient existing on the oven wall (14) is indexed is asked by using the oven wall three-dimensional profile data (701). It can be verified that there is a correlation between this resistance index “k” and a pushing load. Accordingly, it is possible to quantitatively evaluate a state of the oven wall (14) affecting on the pushing load.

  • Patent number: 8297816
    Abstract: A vehicle headlamp includes: a light-emitting module; a control circuit section for controlling a lighting of the light-emitting module; and a reflector including a reflecting face configured to reflect and collect light emitted from the light-emitting module. The control circuit section includes an opposing portion that is opposed to the reflecting face. The opposing portion is disposed at a position away from an optical path of light to be collected by the reflector.

  • Publication number: 20120163008
    Abstract: An automotive headlamp is provided with: a light-emitting module; a control circuit unit configured to control the lighting of the light-emitting module; a support substrate configured to support both the light-emitting module and the control circuit unit; and a reflector configured to reflect, through an inner surface of the reflector, light emitted by the light-emitting module and collect the reflected light. The support substrate is arranged in a manner such that the control circuit unit is positioned in a region outside the reflector.

  • Publication number: 20100177527
    Abstract: In a light emitting module board, an electrode receiving the supply of current for light emission is provided in the light emitting surface of a semiconductor light emitting device. A light wavelength conversion member is a plate-like member mounted on the light emitting surface, and emits light after converting the wavelength of the light emitted by the semiconductor light emitting device. A relay electrode is provided in the surface of the light wavelength conversion member. The relay electrode extends from a position in contact with the electrode to an exposed position in the external space in a state where the light wavelength conversion member is mounted on the light emitting surface. The relay electrode is provided so that the upper part of the relay electrode, which is the exposed position, extends to a position located opposite to the lower part of the relay electrode which is the contacted position.

  • Publication number: 20100149816
    Abstract: In a light emitting module, an electrode receiving the supply of current for light emission is provided on the light emitting surface of a semiconductor light emitting device. A light wavelength conversion member is a plate-like material mounted on the light emitting surface and emits light after converting a wavelength of the light emitted by the light emitting element. The light wavelength conversion member has a notch such that at least a part of the electrode communicates with the external space in a manner perpendicular to the light emitting surface of the semiconductor device when the light wavelength conversion member is mounted on the light emitting surface.
