  • Publication number: 20160056680
    Abstract: The present invention provides an AC generator for a vehicle, in which a resin case (26) includes convex portions (33) formed on an outer circumferential surface of the resin case (26) so as to extend in an axial direction of the resin case (26) to be brought into pressure-contact with an inner circumferential wall surface of a counter drive-side bearing housing portion (24), and convex portions (34) formed on an inner circumferential surface of the resin case (26) so as to be opposed to the convex portions (33). The concave portions (34) allow displacement of the convex portions (33) in a radially inward direction of the resin case (26). By an elastic force generated by the displacement of the convex portions (33), the resin case (26) is integrated with the counter drive-side bearing housing portion (24).

  • Patent number: 9083923
    Abstract: An image forming apparatus performs image formation of a target image with the use of a first color gamut as a standard color gamut for image formation. The image forming apparatus includes a storage section, a color conversion section, and an image forming section. The storage section stores a color expansion table indicating a second color gamut wider than the first color gamut. The color conversion section converts, when a color in the target image is present outside the first color gamut, a color value of the color in the target image to a color value of a coloring material used for image formation on the basis of the color expansion table. The image forming section performs image formation of the target image on the basis of the color value of the coloring material.
