  • Patent number: 10996653
    Abstract: A three dimensional object building device includes a generation unit and a movement controller. The generation unit is configured to generate layer information for each layer of a three-dimensional (3D) object from height information and color information, the height information including information on a three-dimensional position of each pixel of the 3D object, information on a diameter of a dot of build material for the pixel, and information on a gap from an ejection surface of a build unit when the build material for the pixel is to be ejected, the color information indicating a color of each pixel of the 3D object. The movement controller is configured to, when build material for a pixel indicated by the layer information is to be deposited, move the build unit to make a gap correspond to a diameter of a dot for the pixel.

  • Patent number: 8632161
    Abstract: A liquid ejection head includes a common-chamber formation member including a common chamber to supply liquid to pressure chambers communicating nozzles for ejecting liquid droplets, a flexible thin-film member to form part of a wall face of the common chamber, and a thin-film support member bonded to the thin-film member with glue. The support member has an opening or a recessed portion at least partially having a shape that is broad in an area proximal to a first surface of the support member bonded to the thin-film member and becomes narrower as an area of the opening or the recessed portion is more distant from the first surface. The opening or the recessed portion is sealed with the thin-film member. A portion of the thin-film member corresponding to the opening or the recessed portion has the glue on only a periphery area of the portion that contacts the support member.

  • Patent number: 7874656
    Abstract: An ink-feeding device is provided in which the pressure applied to the ink in the printing head can be adjusted arbitrarily irrespective of the relative positions of the ink container and the printing head. Inside the sub-tank 80, a pressure-adjusting pump 82 is installed for applying a suitable pressure to many nozzles 22Kn of the printing head 22K. This pressure-adjusting pump 82 is placed a little above the bottom face of the sub-tank 80 at a prescribed distance from the bottom face. Thereby the pressure-adjusting pump 82 is immersed in the ink held in the sub-tank 80. A drive unit 83 for driving the pressure-adjusting pump 82 is placed above the sub-tank 80. On the upper wall of the sub-tank 80, an air-vent valve 84 is fixed to bring the inside pressure in the sub-tank 80 to an atmospheric pressure. The inside pressure in the sub-tank 80 is made equal to the atmospheric pressure by opening the air-vent valve 84.
