  • Patent number: 9756746
    Abstract: An upper guide and a lower guide are provided on an escutcheon integrally attached to the chassis. An upper movable pin engageable with and disengageable from the upper guide, a lower movable pin engageable with and disengageable from the lower guide, and a fulcrum switching mechanism that reciprocates the upper movable pin and lower movable pin in the left-right direction are attached to a display body disposed in front of the escutcheon. The fulcrum switching mechanism makes the rotational fulcrum of the display body switchable between a first pivoting state, in which the upper movable pin is engaged with the upper guide and the lower movable pin is disengaged from the lower guide, and a second pivoting state, in which the lower movable pin is engaged with the lower guide and the upper movable pin is disengaged from the upper guide.

  • Patent number: 8471473
    Abstract: In a mercury free arc tube provided with a sealed glass chamber in which at least metallic halide for main light emission is sealed as well as rare gas by pinch-sealing both end openings of a glass tube and electrode bars are opposite to each other, the tip of a region projecting into the sealed glass chamber of each the electrode bars is formed of a single crystal. Owing to repetition of ON/OFF of the arc tube, the crystal at the tip of the electrode bar grows but the shape of the electrode end face formed of the single crystal remains unchanged. Further, even if the tip of the electrode bar is gradually consumed by thermal load acting on the tip of the electrode bar, the entire shape of the electrode end face is consumed nearly uniformly so that decline of the luminescent spot does not occur during discharging.

  • Patent number: 8279452
    Abstract: A dimple position detection device for detecting a position of a dimple formed on a load beam is provided with an illumination device, imaging device, and image processing section. The illumination device directs illumination light toward the dimple. The imaging device receives reflected light from the dimple. The image processing section binarizes an image obtained by the imaging device. The image processing section maximizes a binarization level, binarizes the reflected light image, determines whether an area of a light spot region or on-region above the binarization level has a predetermined value, reduces the binarization level when the area of the light spot region is less than the predetermined value, and calculates the gravitational position of the light spot region with the predetermined value reached by the light spot region area.

  • Patent number: 8148902
    Abstract: In a mercury-free arc tube, regions including molybdenum foils 17 of electrode assemblies each of which is formed by connecting and integrating an electrode 16, a molybdenum foil 17, and a lead wire 18, are pinch-sealed where the electrode 16 projects inside a closed glass bulb 12, which encloses luminescent substances, etc. The molybdenum foil 17 is doped with or coated with TiO2 in the form of discontinuous lands and subjected to surface roughening by etching including oxidation and reduction. TiO2 particles or a TiO2 layer exposed on the rough surface 17c of the molybdenum foil 17 increases chemical joining strength to glass and makes deeper, more complicated minute unevenness 17b on the molybdenum foil surface to increase the mechanical joining strength to glass, so that even when a heat stress occurs at the interface between the molybdenum foil and glass in the pinch-sealed portion, foil floating does not occur.
