  • Patent number: 7694601
    Abstract: A housing of a gear device houses a plurality of gears and a lubricant. On at least one side surface of at least one gear selected from the plurality of gears, an extended projection is provided. On a side surface of the housing facing the side surface of the selected gear, an extended projection is provided. The extended projection of the selected gear and the extended projection of the housing extend in a direction crossing the circumferential direction of the selected gear. When viewed along an axial direction of the selected gear, according to rotation of the selected gear, the extended projection of the selected gear and the extended projection of the housing partially face each other in the axial direction of the selected gear and form facing portions. A lubricant holding portion capable of holding the lubricant is formed between the facing portion of the extended projection of the selected gear and the facing portion of the extended projection of the housing.

  • Publication number: 20090262185
    Abstract: The present invention relates to a display apparatus and a display method that enable multiple users to view high resolution moving images from various viewing points of the users. A light-control screen 25 is rotated, and projectors 211 to 21N irradiate the screen 25 from various directions with light rays corresponding to image data captured from those directions. In this case, when the forward direction of the light-control screen 25 is aligned with the projecting direction of one of the projectors 21n, an image corresponding to light rays emitted from the projector 21n is displayed on the light-control screen 25. The present invention may be applied to a display apparatus for displaying images.

  • Patent number: 7537080
    Abstract: An electric power steering apparatus includes a reduction gear mechanism (17) for reducing the rotation speed of an output shaft (16) of an electric motor (15). The reduction gear mechanism (17) comprises an inscribed gear (39) rotatable interlockingly with the output shaft (16), and a circumscribed gear (40) in which the inscribed gear (39) is inscribed. An endless belt connects a driving pulley (41) integrally rotatable with the circumscribed gear (40) and a driven pulley (42) disposed so as to surround a steerable shaft. By heightening the reduction gear ratio by the speed reduction using the inscribed gear (39) and the circumscribed gear (40), the reduction gear mechanism (17) as a whole can achieve a high reduction gear ratio without making the diameter of the driving pulley (41) very small.

  • Patent number: 7488078
    Abstract: A system and method displays a realistic image that allows a user to readily grasp his/her own positional relationship and also to experience a sense of presence. An outer dome screen is disposed so as to surround a user, and an immersion image such as the scenery of the surroundings of an object is displayed thereon. An inner dome screen is disposed inside the outer dome screen, and it displays a bird's-eye image of the object as perceived by the vision of the user when the object is viewed from a viewpoint of the user. In this case, the user is allowed to readily grasp his/her own positional relationship by the bird's-eye image and is allowed to experience a sense of presence by the immersion image.
