  • Patent number: 8876195
    Abstract: A shock absorber includes a first shock absorbing member formed of a foam, and a second shock absorbing member formed of a foam and having hardness greater than the first shock absorbing member. The first shock absorbing member and the second shock absorbing member are arranged in adjacent to each other and connected to each other such that a part of one of the first shock absorbing member and the second shock absorbing member is surrounded by another one of the first shock absorbing member and the second shock absorbing member, thereby the first shock absorbing member and the second shock absorbing member are connected integrally with each other.

  • Publication number: 20120037223
    Abstract: An object of the present invention is to provide a binder resin for a conductive paste, which can be used to obtain a conductive paste having a high conductive powder dispersibility, an ability to form high-aspect-ratio lines, and a low residual carbon content after firing. Further objects of the invention are to provide a conductive paste and a solar cell element produced using such a binder resin for a conductive paste. The invention provides a binder resin for a conductive paste, which includes a polymer having a main chain composed of a segment derived from a (meth)acrylate monomer and having also a phosphoric acid-based component represented by general formula (1) below at an ? position thereon. In general formula (1), X is an oxygen atom or a sulfur atom, and R1 and R2 are each a hydrogen atom, a hydrocarbon group having 1 to 13 carbon atoms, a hydroxyl group-containing group having 1 to 13 carbon atoms or an ester bond-containing group having 1 to 13 carbon atoms.

  • Patent number: 7743827
    Abstract: Remote operation wire line core sampling device capable of increasing efficiency of working and maintaining a wall of a hole using a stabilized sea-bottom core drill at a sea-bottom, and adopting a wire line system. The device includes a drill rod held by a chuck of the sea-bottom core drill, a wire line core barrel having, at a tip thereof, a bit for annularly drilling into ground, an inner tube assembly detachably incorporated in the wire line core barrel, and an over-shot assembly having a function for engagement thereof with a spear head part at a top end of an inner tube assembly. The device also includes a water swivel in which water supply ports are formed at upper and lower parts thereof, a modified built-in type over-shot assembly is formed at upper and lower parts thereof, and a modified built-in type over-shot assembly is incorporated therein to reside at an intermediate part thereof.

  • Patent number: 4614249
    Abstract: A four-wheel drive vehicle of the type wherein the rider straddles the vehicle. The frame includes an upper frame structure which extends outwardly and downwardly to widely-based supports for the front axle while maintaining a narrow profile at the upper portion thereof. The lower frame structure extends rearwardly from a front axle support structure inwardly of the upper frame structure. As the upper frame structure converges, the lower frame structure extends laterally outwardly of the upper frame structure. Broad support for the front axle is provided by the upper frame structure while broad support for the engine and footpegs is provided by the lower frame structure.
