  • Publication number: 20050222469
    Abstract: The invention relates to a process for producing a fatty alcohol, including hydrogenating a fatty acid ester to prepare a crude fatty alcohol product, and distilling and refining the resulting crude fatty alcohol to prepare a fatty alcohol, further including recovering a part or the whole of distillation residues obtained in the distillation step and removing an alkali component from the distillation residues, adding the treated distillation residues to hydrogenation step or to a starting fatty acid ester feed.

  • Patent number: 6820867
    Abstract: A fluid-sealed anti-vibration device is provided, in which a cone-shaped mounting section provided with an elastic body section which generates membrane resonance, and a cylindrical bushing section provided with an end wall and an elastic partition wall which also generate membrane resonance are integrally provided. When the fluid is filled and sealed in the cone-shaped mounting section and the cylindrical bushing section, the characteristics where a fluid is sealed in only the cone-shaped mounting section and the characteristics where the fluid is sealed in only the cylindrical busing section are coupled. Furthermore, the dynamic spring peaks and the dynamic spring bottoms, which are generated one by one in both sections, cancel each other. As a result, it is possible to realize the low dynamic spring effect in a wider frequency range by lowering the dynamic spring peak.

  • Patent number: 6443438
    Abstract: A cone-shaped mounting (1) is provided in which a main fluid chamber (10) is formed by a first connecting member (3) a second connecting member (5), an elastic body member (7), a partition member (8) and a first orifice passage (15). A part of an elastic wall of the main fluid chamber (10) is an inner wall of the elastic body member (7). The first orifice (15) communicates with a sub-fluid chamber (11). An input direction of a main vibration is arranged to be the Z-axis direction (the vertical direction of a car body). Side fluid chambers (20) and recessed chambers (25) are alternately provided at intervals of 90° in the circumferential direction on the outer circumference of the elastic body member (7). An outer wall of the elastic body member (7) forms a part of an elastic wall of the side fluid chambers (20). A pair of side fluid chambers (20) is disposed in the longitudinal direction of the car body.

  • Patent number: 6267362
    Abstract: A liquid chamber is arranged with a first support member 1, a second support member 2 and an elastic member 3, an inside of the liquid chamber is divided to a main liquid chamber 11 and an auxiliary liquid chamber 12 by a partition member 10 and both chambers are communicated with a damping orifice passage 14 and an idle orifice passage 15. On an inner face of a conical portion 4 of the elastic member 3, thin wall portions 7 are provided by forming recess 6 at axially symmetrical position so as to yield a minimum value for a dynamic spring characteristic against a vibration input in a designated medium frequency by a membrane resonance. A non-circular medium to high frequency device 20 projecting into the main liquid chamber 11 is provided to the first support member 1 so as to resonate by liquid column against a vibration input in a designated high frequency.

  • Patent number: 6170810
    Abstract: A liquid sealed type bushing including an outer cylinder, an inner cylinder and an elastic member. Recesses are formed on a middle portion of the elastic member. The elastic member between the recesses is adapted to be a partition member and a thin wall portion is formed by providing a through hole in the partition member, and an outer peripheral portion of the partition member is made to contact but not combine with an inner face of the outer cylinder. Within the recess, a medium to high frequency device is supported by the inner cylinder. By overlapping a peak caused by a membrane resonance owing to the thin wall portion of the partition member, and a minimum value caused by a liquid column resonance of the medium to high frequency device, a low dynamic spring constant is attained in a medium to high frequency region.

  • Patent number: 5773126
    Abstract: A composite film that, when used as a protective film or an antireflection film for e.g., a polarizing film of a liquid crystal display, has a surface slip property good enough to be rolled and excellent mechanical and chemical resistance and optical properties. In one aspect, the composite film has a substrate film and a hard coat layer provided on the substrate film, the hard coat layer formed of an ionizing radiation-cured resin, the surface of the hard coat layer having fine irregularities serving to create a surface slip property. In another aspect, the composite film has a substrate film and a hard coat layer provided on the substrate film, the hard coat layer formed of a composition comprising an ionizing radiation-cured resin, fine particulates of inorganic and/or organic materials, and an organic silicone.
