    Abstract: New latex articles containing nano-silver and the preparation thereof are disclosed. The latex articles, which contain nano-silver, are manufactured by molding the latex containing nano-silver or coating the molded latex articles with the lubricant containing nano-silver. The inventive processes are easy and the molded articles can not only be antibacterial, but also be bacteriostasis and bactericidal. So the safety in using it is greatly improved and the cross infection of bacterias is prevented essentially. The said articles are condoms and gloves etc which meets the strict requirement of sanitary.

  • Publication number: 20090305917
    Abstract: To provide a sliding material whose superficial sliding characteristics can be modified in compliance with the requirements of sliding component parts without ever changing the surface roughness of sliding material very much by means of shot blasting treatment, and to provide a sliding member using the sliding material. A sliding material according to the present invention is characterized in that it comprises: a metallic substrate; and an adhered metal being formed by mechanical adhesion by means of shot blasting metallic particles, which are softer than said metallic substrate and whose friction coefficients are smaller than that of said metallic substrate, onto a sliding surface of said metallic substrate so as to cover 8% or more of the sliding surface of said metallic substrate.

    Abstract: A bi-metal aluminum bearing includes an aluminum-based bearing layer, a steel backing, and an intermediate aluminum-based layer that has a thickness of from 60 to 120 micrometers positioned between the aluminum-based bearing layer and the steel backing. The intermediate layer has a yield strength that is less than that of the aluminum-based bearing layer and is preferably of pure aluminum. The aluminum-based bearing layer has a fine microstructure which imparts a very high level of conformability while retaining good fatigue strength. The aluminum bearing layer generally includes 4% to 20% by weight lead or tin, up to 26% by weight silicon and up to 2% by weight of any of the elements magnesium, manganese, nickel, zirconium, zinc, copper, or chromium with the remainder of the bearing layer being aluminum.
