    Abstract: Disclosed is a friction stir welding technique which avoids occurrence of a dent, in adjoining region, extending to a level beneath the joined surfaces. At end portions of the frame members to be joined, at the joining region, thickened parts which project toward the rotary body joining tool are provided. Two adjoining thickened parts, of adjacent members to be joined, can form a trapezoid shape. The rotary body joining tool has a small-diameter tip portion and a larger diameter portion. The rotary body joining tool is inserted in the thickened parts. In a state where the rotary body joining tool has been inserted small-diameter tip and first, to a level where the larger diameter portion of the rotary body joining tool overlaps the thickened part but does not extend below the upper surface of the non-thickened surfaces of the members joined, the rotary body is rotated and moved along the joining region. Even when a gap exists between two thickened parts, a desirable joining can be carried out.

  • Patent number: 6136406
    Abstract: A tailored structural member that is designed to generate a yield-type response, with applicability to the arrest of a moving body. The structural member comprises a primary load path connected in parallel to a longer secondary load path at a pair of common nodes. The primary load path is designed to fail at a lower load than that required to fail the secondary load path when subjected to a tensile force. As a result of the load redistribution achieved through the use of the redundant paths provided by the primary and secondary load paths, the structural member dissipates more kinetic energy from the moving body within a given set of displacement and deceleration force constraints than is possible using a conventional, uniform cross-section member.

The magnetic element exhibits a continuous magnetic reversal under an applied alternating magnetic field having a magnitude that is smaller than the coercive force of the second thin film to cause said first thin film to undergo magnetic reversal. The magnetic element also exhibits a discontinuous sudden magnetic reversal under an applied alternating magnetic field having a magnitude that is greater than the coercive force of the second thin film. The configuration of the magnetic element has little effect on discontinuous magnetization response. Thus the magnetic element exhibits good magnetic characteristics even when formed in a small size.

  • Patent number: 5891548
    Abstract: A curable silicone is used to encapsulate porous, photoluminescing silica nanoparticles having three-dimensional, web-like structures. The encapsulation protects the silica nanoparticles, preserves their photoluminescent effect, and can be used as a coating. The composition is used to prepare articles of manufacture by casting it on a substrate such as glass or a silicon wafer and curing it. Special effects can be obtained by using a mask on the substrate prior to deposit of nanoparticles and curing the silicone matrix.

  • Patent number: 5871832
    Abstract: A guide for leveling the flow of a coating from a nozzle onto a generally cylindrical substrate of a polymeric printing component in a printing machine is provided. The substrate is rotated about its longitudinal axis by a turning apparatus having a axially movable slide for mounting the nozzle to the slide. The coating is spirally applied to the substrate. The guide includes a member operably associated with the slide and moves with the slide. The member has a surface parallel to and slightly spaced from the periphery of the substrate so as to assist in evenly distributing the coating on the periphery of the substrate.

  • Patent number: 5843555
    Abstract: A pattern-bearing sheet for a simultaneous injection-molding and pattern-forming method, has a sufficient malleability in the following conditions. When the sheet is cut to a 10-mm width and subjected to a tensile load and thus elongated at a rate of 30%/second in an environment at 50.degree. C., the sheet should exhibit a stress value of 0.6 kg or higher at the yield point and after passing through the yield point in the case where the sheet is formed from a material having a yield point, and the sheet should exhibit a stress value of 0.6 kg or higher at an elongation of 10% and higher in the case where the sheet is formed from a material not having a yield point. Desirably, the value when the sheet cut to 10-mm width is elongated at a rate of 7%/second to an elongation of 200% (200% modulus value) at a temperature of 100.degree. C. to 120.degree. C. should be 0.3 kg or lower.
