  • Patent number: 8973887
    Abstract: In a slide structure, a support structure and a seismically isolated structure, a first sliding surface (25) of a sliding member (21) is formed of a sliding body (24) made of synthetic resin. A film (27) made of synthetic resin and having a Young's modulus more than twice as large as that of the first sliding surface (25) is formed on the second sliding surface (28) of the counter member (22). At the same time, fine irregularities having a maximum height Rz of 3 ?m or higher are formed on the surface of the film (27). As a result, the lubricant is trapped in small pits of the irregularities to prevent the lubricant from flowing out, and a stable low friction state can be maintained.

  • Patent number: 7850165
    Abstract: A paper sheet storing apparatus is configured to collect and accumulate multiple different types of paper sheets in different sizes. The paper sheet storing apparatus has: a paper sheet cartridge configured to have a feeder provided on a side wall thereof for externally feeding paper sheets and arranged to accumulate and keep the paper sheets therein; and a stack guide member configured to introduce the paper sheets, which are fed by the feeder into the paper sheet cartridge, downward in the paper sheet cartridge and to press down surface of an uppermost paper sheet located on a top of the paper sheets accumulated and kept in the paper sheet cartridge. The stack guide member is structured in a specific shape to enable the surface of the uppermost paper sheet to be pressed downward in a vertical direction, with regard to all the multiple different types of paper sheets. This arrangement effectively reduces the potential for paper jams and relevant troubles and ensures stable accumulation of paper sheets.

  • Patent number: 7225588
    Abstract: A damping brace having an axial force member for providing bearing forces against tensile or compressive forces, a constraining member for constraining the axial force member, and a stiffening part for supplementing the stiffness of the axial force member. An adhesion preventive coating is provided for preventing adhesion between the constraining member and the stiffening part. A length of the stiffening part extending along the axial direction and the gap between the stiffening part and the constraining member are defined in such a way as to prevent an end of the axial force member from rotating in the axial direction beyond a specific angle when the compressive force is applied to the force member.

  • Patent number: 7031641
    Abstract: An image-forming apparatus includes a pre-charge exposure device which removes electric charge from a photoconductor drum to increase a potential contrast between the surface of the photoconductor drum and the surface of a charge roller in an upstream region of a nip region between the photoconductor drum and the charge roller in the rotating direction of the photoconductor drum, so that toner accumulating in an upstream region of the nip region in the rotating direction of the photoconductor drum is restrained and prevented from being discharged onto an image-forming region. When the toner accumulating in the upstream region of the nip region in the rotating direction of the photoconductor drum is to be discharged onto a non-image-forming region, the pre-charge exposure device is turned off so that the potential contrast decreases.
