  • Patent number: 11535173
    Abstract: At a camera device for a vehicle, a camera images an obverse side of a glass cover via the glass cover. A water repelling film is formed on an obverse side surface of the glass cover. A transparent conductive film of the glass cover generates heat, and the glass cover is heated. Because the transparent conductive film is electrically conductive, electrical resistance of an obverse side surface of the water repelling film can be lowered by the transparent conductive film, and charging of the obverse side surface of the water repelling film can be suppressed.

  • Patent number: 9033527
    Abstract: In a vehicle door mirror device, by a first fixed-face of a fixed projection of a stay and a first rotating-face of a rotating projection of a drive body contacting, further rotation of a mirror is inhibited when the mirror is disposed in a housed position. A slope-angle of the first fixed-face to the housing direction is smaller than a slope-angle of the first rotating-face to a forward folded direction. Contact between the upper end of the first fixed-face and the first rotating-face can accordingly be restricted, and a distance from the lower end of the first fixed-face to the contact position with the first rotating-face can be made short. So, moment acting on the first fixed-face from the first rotating-face can be made small, enabling damage to the lower end position of the first fixed-face to be suppressed. A reduction in weight and cost can accordingly be achieved.

  • Patent number: 6583919
    Abstract: An electrochromic anti-glare mirror is provided in which incorrect assembly can be prevented, assemblability can be improved, a number of work processes can be reduced, and costs can be reduced. The electrochromic anti-glare mirror includes an electrochromic layer which is provided at a rear surface side of a substrate glass, and in which an electrochromic film is nipped between a transparent conductive film and a reflective conductive film. By energizing the electrochromic film between the transparent conductive film and reflective conductive film, the electrochromic film is electrically made to color. Wires for electrochromic anti-glare for energizing the electrochromic film between the transparent conductive film and the reflective conductive film are printed on the printed circuit board. As a result, there is no need for complex work for installing and connecting cords as in conventional structures in which wires are cords.

  • Patent number: 6288731
    Abstract: In an image processing apparatus, a figure data storage unit stores a figure data for a figure, and pixels of the figure data are allocated with figure data addresses. A display buffer unit stores a display figure data, and an object table unit stores an object table which storing a set of display parameters for a deformed figure of the figure. The object table unit outputs the set of display parameters in response to an object designating instruction. An address generating unit stores at least a form table which stores ones of the figure data addresses for the deformed figure as deformed figure addresses. The address generating unit outputs, as read addresses, addresses including the deformed figure addresses to the figure data storage unit based on the set of display parameters supplied from the object table unit to read out at least a portion of the figure data from the figure data storage unit, and stores the read out figure data portion in the display buffer unit as the display figure data.
