  • Al-based bearing alloy and slide bearing using same
    Patent number: 11493086
    Abstract: An Al-based bearing alloy and a slide bearing incorporating the alloy exhibit high corrosion resistance and maintain high strength for a long period of time even in a high temperature environment. The Al-based bearing alloy and slide bearing includes an Al matrix, and acicular compounds which are needle-shaped that precipitate at a plurality of sites in a structure of the Al matrix, and that have a minor diameter and a major diameter.
    Type: Grant
    Filed: March 28, 2017
    Date of Patent: November 8, 2022
    Assignee: DAIDO METAL COMPANY LTD
    Inventors: Kei Ishikura, Akihiro Kose, Kazuaki Toda, Eisaku Inoue
  • Composition for resin surface roughening
    Patent number: 11084915
    Abstract: Provided is a means capable of realizing a surface-roughening method for modifying the surface of a resin molded article to form a surficial layer, such as a coating or plating, or to impart a function derived from the surface configuration. The method comprises adding a resin composition and performing a post-treatment and is thus simpler and easier than conventional methods. The resin composition is a composition for resin surface roughening that contains an aliphatic polycarbonate and an alkali metal salt.
