  • Publication number: 20040170449
    Abstract: A developing roller and an image forming device capable of securely obtaining high-quality images are provided. In the developing roller having at least one resin outer layer 3a formed on the outer periphery of an elastic layer 3, the resin outer layer is made of an ultraviolet-curable resin or an electron-beam-curable resin. The resin outer layer 3a contains fine particles of which mean particle diameter is 1-50 &mgr;m and a conductive agent such as an ionic conductive agent or an electronic conductive agent. Preferably used as the fine particles are silicone rubber, fluororubber, melamine resin, phenol resin, glassy carbon, urethane elastomer, and the like. The ratio of the mean particle diameter “a” of the fine particles and the thickness “b” of the resin outer layer 3a, i.e. “a/b”, is preferably in a range of 0.05 to 0.5.

  • Patent number: 6760081
    Abstract: A liquid crystal display (LCD) device having uniform feedthrough voltage components. The LCD device comprises a LCD panel and a backlight portion for illuminating the LCD panel from the backside. The LCD panel has: a plurality of pixels which are disposed in a matrix having rows and columns and each of which has at least a thin film transistor (TFT) and a pixel electrode; a plurality of gate signal lines which extend from a gate signal input portion disposed along a side of the liquid crystal display panel and each of which is coupled with the TFT's in a row of the matrix; and auxiliary capacitor portions each additionally coupled with a pixel electrode of one of the pixel. The width of the gate signal line becomes narrower and thereby capacitance of the auxiliary capacitor portions becomes smaller as the distance from the gate signal input portion becomes larger. Also, luminance of backlight by the backlight portion becomes lower as the distance from the gate signal input portion becomes larger.

  • Patent number: 6638632
    Abstract: There is disclosed a rubber composition comprising (A) butadiene rubber and/or (B) isoprene rubber in the form of liquid and (C) silicone rubber at a {(A)+(B)}/(C) ratio by weight in the range of 97/3 to 5/95. The composition is capable of affording an elastic member which has a low hardness and excellent wear resistance, and which is well suited for use in a variety of part items that are installed in an image formation apparatus such as an electrophotographic apparatus and an electrostatic recording apparatus, including copying machinery, printers, facsimile apparatus and the like, in particular a developing roller. There are also disclosed a developing roller which comprises the above rubber composition, is improved in wear resistance for a developer without causing high hardness thereof, and is capable of affording a steadily favorable image without fail for a long period of time; and further a developing apparatus which comprises the above developing roller.

  • Patent number: 5406168
    Abstract: A color picture tube grid apparatus includes a mask, a frame, and a belt-like metal plate. The mask is constituted by an array of a large number of stretched grid elements defining a large number of slit holes. The frame has a pair of side frame portions for supporting the mask at two end portions of each of the grid elements in a stretching direction. The belt-like metal plate is in contact with end portions of the grid elements and arranged on at least one of two end portions of the mask to cross the array of grid elements.
