  • Patent number: 10330534
    Abstract: A backing member (50a) is pressed in a perpendicular direction (D3) by a predetermined sheet conveyed to a colorimetric position (P), and is disposed behind the predetermined sheet at the colorimetric position (P) when viewed from a colorimetric unit (40). A supporter (90) supports the backing member (50a) in a manner that the backing member (50a) can move in the perpendicular direction (D3). Holders (23a, 23b, 23c) hold a color tile member (80a) disposed on the backing member (50a) in a state that the amount of movement of the backing member (50a) in the perpendicular direction (D3) by the color tile member (80a) being thicker than the predetermined sheet and disposed on the backing member (50a) is larger than the amount of movement of the backing member (50a) in the perpendicular direction (D3) by the predetermined sheet.

  • Patent number: 10315591
    Abstract: A wire harness includes an exterior member having a tube shape. The exterior member includes a flexible tube part formed in a flexible bellows tube shape and a straight tube part. The straight tube part is formed continuously with the flexible tube part so as to arrange the conductive path straight and has a non-bellows tube shape. A continuous portion between the flexible tube part and the straight tube part includes a tapered portion formed in a whole peripheral direction of the exterior member so as to reduce stress concentration in the continuous portion. An inner peripheral surface and an outer peripheral surface of the tapered portion include slopes connecting a top of a bellows projection of the flexible tube part and the straight tube part, or connecting a groove bottom of a bellows recess of the flexible tube part and the straight tube part.

  • Patent number: 10282828
    Abstract: An image processing apparatus includes a setting unit and a conversion unit. The setting unit sets a gradation threshold. The conversion unit converts a gradation value greater than the gradation threshold in an input image into a predetermined gradation value, converts a gradation value equal to or less than the gradation threshold in the input image into a gradation value equal to or less than the predetermined gradation value, and generates an output image. In a case where the input image is an image processed in such a manner as to enhance a predetermined area, the setting unit sets the gradation threshold such that a surrounding area of the predetermined area of the input image becomes equal to or less than the gradation threshold.
