    Abstract: A container for receiving or storing or carrying pistons for injectors, the container having a base plate and hollow cylindrical piston storage parts (the container being hereafter referred to as a piston nest). Each of the hollow cylindrical piston receiving parts is formed either by making it vertically penetrate through the basic plate, with one side of the base plate functioning as one opening end, and project from the other side or by making it vertically penetrate through the base plate and project from both sides of the base plate. Preferably, each piston receiving part has a swelled part where a part of the inner peripheral wall surface of the piston receiving part is swelled inward. The pistons for injectors are received in the piston receiving parts.

  • Patent number: 8932193
    Abstract: A sheet feed rolling element for an electrophotographic device includes a roller portion and shoulders on both sides formed by curved chamfers. A parting line between the fixed mold plate and the movable mold plate of an injection mold is located at the boundary between one shoulder and the roller portion outer periphery, a step is provided at the boundary due to a difference between the opening diameter of the cavity portion defined by the fixed mold plate and the opening diameter of the cavity portion defined by the movable mold plate so the one shoulder has a smaller diameter than the outer peripheral surface, and a chamfer is provided adjacent to the one shoulder to absorb any difference in molding shrinkage rate due to a difference in molecular orientation of resin at the step, thereby preventing circumferential bulging on the outer periphery of the formed roller portion.

    Abstract: A rubber composition contains a higher ethylene content EPDM and a lower ethylene content EPDM as a rubber component. The proportion of the higher ethylene content EPDM is 30 to 80 mass % based on the overall amount of the rubber component. The rubber composition is less susceptible to reduction in friction coefficient ? and has a proper hardness, a smaller permanent elongation and an excellent abrasion resistance after crosslinking. Therefore, the rubber composition is suitable for a sheet conveying roller and an image forming apparatus incorporating the sheet conveying roller.

The specific combination of the constituents of the MCrAlY formulation advantageously allows significantly high loadings of ceramic (metal oxide) while still retaining the ability to selectively oxidize aluminum to form alumina scale, a property previously not attainable with conventional MCrAlY materials when loaded with ceramics at levels of 15-45 weight percent. The alumina scale in combination with the modified MCrAlY formulation act as a barrier to specific detrimental oxide formations.

  • Patent number: 7947149
    Abstract: A web of a first sheet material and a web of a second sheet material are laminated together by a process wherein the sheet materials are wound, in an interleaved relationship, upon a roller having a radially displaceable outer surface. The roller and webs and then subjected to heating and/or a low-pressure environment so as to complete the lamination. A body of adhesive material, such as a hot melt adhesive, may be interposed between the webs and the heating or low pressure environment can activate this adhesive. Further disposed are particular configurations of rollers with radially displaceable surfaces.

  • Patent number: 7922637
    Abstract: The present invention provides a conductive roller which has excellent resilience in response to deformation and exhibits small variation in electrical resistance. The conductive roller has a metallic core, a conductive elastic layer formed on the outer surface of the core to which layer conductivity has been imparted by carbon black, and a surface-treated layer formed through impregnating a surface of the conductive elastic layer with a surface-treatment liquid, wherein the difference ?Hs (Hs1?Hs2) between micro-hardness Hs1 of a surface of the conductive roller and micro-hardness Hs2 of the conductive elastic layer after removal of the surface-treated layer, the hardness being determined by means of a micro-hardness tester, is 5% or less of the micro-hardness Hs2.

  • Publication number: 20110039672
    Abstract: Conventional art has a structure consisting of a roll axis incorporating a structure of fine pores, and a roll unit provided around the outer circumference of a roll axis, wherein internal pressure of the roll axis is dispersed to the roll unit to make a fluid (gas-liquid) suction action, thus reducing the pressure loss and obtaining even distribution of the fluid (gas-liquid). As such, instead of a tubular roll axis, the structure of a roll axis is made fin-shaped or groove-shaped to maximize the action surface area that works on the inner pressure of the roll axis of the roll unit. However, other problems such as inefficiency of the fluid (gas-liquid) suction action and lack of mechanical strength of the roll axis remains.

  • Patent number: 7881646
    Abstract: A developing roller suppresses scattering of toner during a developing process and provides a further higher-quality electrophotographic image. The developing roller has a mandrel, an elastic layer provided on the circumference of the mandrel, and a surface layer provided on the circumference of the elastic layer. The surface layer contains a urethane resin serving as a binder and urethane resin particles dispersed in the binder, for forming convex portions on the surface of the surface layer. The surface of the urethane resin particles is partly covered with fine inorganic particles containing at least one element selected from silicon, titanium and aluminum and the urethane resin particles are in direct contact with the binder at the surface onto which the fine inorganic particles are not attached.

  • Publication number: 20100298107
    Abstract: The present utility model is a nylon conveyance roller used for the lifting platform loader of aircraft cargo transit wagon, wherein there is a tunnel going through the said roller for placing the axle. The tip and toe of the said roller are provided with plane structure, and the outer surface of the said roller is frosted texture. The material Nylon, designed for making the said conveyance roller, is suitable. It can increase the friction between the roller and the floor of container and container plate during cargo conveyance, making skidding conditions or noise during rotating friction unlikely. By using nylon as material, the said roller can boast good wear resistance, low noise, a slim likelihood of skidding condition, and environmental compliance.

  • Patent number: 7824514
    Abstract: A method of producing a stretch laminate exhibiting reduced defects from a mechanical activation process can include providing a nipping member. The nipping member can have a first nip region and a non-nip region adjacent to the first nip region. A first substrate and an elastic element are provided to the nipping member. The first substrate and the elastic element are joined in a face to face relationship with adhesive therebetween, thereby creating an intermediate laminate. The intermediate laminate has a first tack down region and an activation region adjacent the first tack down region. A portion of the first tack down region passes through the first nip region, and a portion of the activation region passes through the non-nip region of the nipping member. The activation region of the intermediate laminate is mechanically activated, thereby creating the stretch laminate.

  • Publication number: 20100210434
    Abstract: The present invention is a laser engravable embossing roll exhibiting improved wear characteristics and life span through the use of an epoxy resin based material. Specifically, the embossing roll according to the present invention can be produced using standard laser engraving techniques that have heretofore been applied to rubbers. Rubber rolls, while produced significantly faster than engraved steel rolls, have the disadvantage of poor life span due to wear. The epoxy based resin rolls of the present invention overcome these disadvantages by being quickly and easily produced using laser engraving but exhibiting significantly improved wear characteristics.
