  • Patent number: 10962101
    Abstract: A transmission case (10) includes a case (2) and a side cover (3). A rotation sensor (5) including a connector terminal part (52) is attached to the side cover (3). A seal member (FIPG) (4) is interposed between joining surfaces (22a, 32a) of the case (2) and the side cover (3). A notch portion (25) where the seal member (4) is accumulated is provided to an outer peripheral surface (22b) of the joining surface (22a) which is adjacent to the connector terminal part (52). Accordingly, the amount of the seal member (4) protruding outward from the outer peripheral surface (22b, 32b) of the flange portions (22, 32) is reduced, thus suppressing connection failure of a connector.

  • Patent number: 8032531
    Abstract: A system is provided for specifying arbitrary nodes and identifying a section between them on a system diagram of a distribution system. It comprises a system diagram information management portion for managing information on each of nodes and spans constituting the system diagram and ID information given to each of the nodes, an input portion for receiving an input specifying the nodes, a search portion for creating a search condition using the ID information based on the node specification and searching the span between the specified nodes so as to identify the section constituted by the searched span, and an output portion for display-outputting the system diagram visually indicating the section identified by the search portion.

  • Patent number: 7196845
    Abstract: A Fresnel lens sheet comprising a Fresnel lens substrate and a Fresnel lens, whose surface of the light source side has an average pitch of 200 ?m or smaller and ten point roughness of 3 to 15 ?m, a rear projection screen obtained by assembling the Fresnel lens sheet and a lenticular lens sheet, and a process for producing these. With the use of the Fresnel lens sheet and the rear projection screen in accordance with the present invention, a labyrinth light inside the screen and a surface reflection are diffused effectively and a ghost caused by them is remarkably reduced. Accordingly, the rear projection television employing the Fresnel lens sheet and the rear projection screen of the present invention provides excellent images without ghost light.

  • Patent number: 6917469
    Abstract: A light diffusing laminated plate including a first light diffusing layer containing particles of a transparent light diffusing material dispersed therein and having a concave cross-section, and a second light diffusing layer containing particles of an opaque light diffusing material dispersed therein and having a convex cross-section. The first and second light diffusing layers are laminated together such that the convex and concave surfaces are face to face contact with each other to form a curved interface therebetween. The first and second light diffusing layers have a substantially uniform cross-section in one direction. A transmissive screen for a rear projection display device having a light image source, including the above light diffusing laminated plate and a lens system disposed such that a light image from the source is projected through the light diffusing laminated plate and the lens system and displayed on the screen.

  • Patent number: 6313184
    Abstract: Propylene resin beads for molding expansion molded articles having improved high temperature resistance include as base resin metallocene-catalyzed copolymers of propylene with at least one or more of ethylene and ∝-olefins of 4 to 20 carbon atoms. The metallocene-catalyzed propylene copolymers are isotactic random copolymers characterized by a melting point higher than 140° C. to 160° C. and a melt flow rate (MFR) of not higher than 12 g/10 minutes, especially, 0.5 to 12 g/10 minutes. Expansion molded articles produced by expansion molding the expanded beads have a high temperature degree of deflection which is lower than that of metallocene-catalyzed propylene homopolymers and lower than that of Ziegler-Natta-catalyzed random propylene copolymers having the same comonomers and melting point.
