    Abstract: Laminated metallic sheets which comprise an interior layer of a viscoelastic polymeric compound sandwiched between outer layers of metallic sheet may exhibit enhanced properties through modification of the viscoelastic phase. In a first embodiment the elastic modulus of the viscoelastic polymeric compound may be reduced by incorporating voids, bubbles or pores within the compound. These voids which may be introduced by introduction of polymeric microspheres are effective in reducing the internal stresses induced in the laminate by temperature changes. In a second embodiment, coating the microspheres with an electrically-conductive layer may be effective in enabling resistance spot welding of such laminated materials.

  • Patent number: 6242097
    Abstract: There is disclosed a cable having a covering layer on the outside of a multicore stranded wire composed of plural insulated conductors that are intertwined, wherein at least an outermost layer of the covering layer is made of a crosslinked product of a resin composition containing (a) 10 to 60% by weight of a polyamide elastomer made up of a block copolymer whose hard segment is a polyamide, (b) 5 to 60% by weight of a thermoplastic polyurethane resin, (c) 10 to 60% by weight of a thermoplastic polyester elastomer, and (d) 0 to 20% by weight of a thermoplastic styrene elastomer. The airtightness and the watertightness at the interface between the cable and a molded body are kept for extended periods without taking any particular sealing measures. The corrosion of the conductors in the cable and the deterioration of the performance of the connected parts of machinery and tools can be prevented, and the cable has excellent water resistance.

  • Patent number: 6202462
    Abstract: A noise-damping composite is formed by providing a laminate of two metal layers separated by a much thinner viscoelastic layer which has an initial thickness of at least 1 mil., and then cold rolling the laminate to proportionally permanently reduce the thickness of each layer, until the thickness of the viscoelastic layer is less than 1 mil. and preferably less than 0.5 mil. The cold rolling may be through a set of adjustable rollers, and may be done in multiple passes with the rollers adjusted for each pass to further reduce the thickness. Alternatively, the laminate may be fed successively through a series of roller sets designed to successively reduce the thickness of the laminate.

  • Patent number: 6193835
    Abstract: A process for producing a rubber-based composite material including steps of laminating a rubber compound onto a substrate, with a bonding layer of metal or metal compound interposed therebetween, and subsequently vulcanizing the rubber compound, characterized in that a prime-coating film is interposed between the substrate and the bonding film of metal or metal compound. The rubber-based composite material retains good bond strength even when used in such a way that its bond interface is in contact with water. In addition, it has good adhesion to the substrate treated by conversion treatment.

  • Patent number: 6046907
    Abstract: A heat conductor used by being disposed between a heat sink and electronic parts mounted on a printed circuit board. The heat conductor is layered by a heat conductive layer, made of silicone gel with alumina as a heat conductive filler dispersed therein, and a potentially adhesive layer. The potentially adhesive layer consists of a hot melt layer, with alumina as a heat conductive filler dispersed therein, and a heat resistant film, to facilitate formation of the hot melt layer, adhered to the heat conductive layer on one face of the heat resistant film. The heat conductor is set on the electronic parts so that the potentially adhesive layer abuts them, and is made to adhere to the electronic parts due to heating by means of reflow soldering to reach the phase change temperature of the adhesive.

  • Patent number: 5888321
    Abstract: The steel wire for making steel cord used in rubber product reinforcement has a tensile strength, Y in N/mm.sup.2, such that Y.gtoreq.-1960d+3920, wherein d is the wire diameter in mm, and also a flat Vickers hardness distribution in a cross-section perpendicular to a length direction thereof from the surface to the interior, but excluding a central portion having a central portion diameter corresponding to 1/4 of the wire diameter. The steel wire is made by a method including wet drawing a carbon steel wire rod material containing 0.80 to 0.89% by weight carbon to a predetermined intermediate diameter and subsequently heat-treating and plating to form a final raw material and then wet drawing the final raw material to form the steel wire. The wet drawing steps are performed with drawing dies, each of which is provided with a drawing hole having a drawing hole diameter d.sub.1 and the drawing die has an approach angle 2.alpha. equal to from 8.degree. to 10.degree. and a bearing length of 0.3 d.sub.1.
