  • Patent number: 11189393
    Abstract: A conductive coated composite body is disclosed which has both good adhesion of a conductive coating film to a base and excellent electrical conductivity of the conductive coating film at the same time even in cases where a glass base or a base having low heat resistance is used; and a method for producing this conductive coated composite body. A conductive coated composite body includes: a base; a resin layer that is formed on at least a part of the base; and a conductive coating film that is formed on at least a part of the resin layer. The conductive coating film is a sintered body of silver fine particles; the main component of the resin layer is a polyurethane resin having an elongation at break of 600% or more; and the polyurethane resin has one of the functional groups represented by —COO—H, —COOR, —COO?NH+R2 and —COO?NH4+.

  • Patent number: 10427251
    Abstract: Provided are a fine silver particle dispersion which exhibits low temperature sinterability and in which fine silver particles are uniformly dispersed in a variety of solvents (and especially highly polar solvents); fine silver particles that exhibit low temperature sinterability and excellent dispersion stability in a variety of solvents (and especially highly polar solvents); a dispersion obtained using the fine silver particles; and a method for producing same. The fine silver particle dispersion is characterized by containing fine silver particles, a short chain amine having 5 or fewer carbon atoms, and a highly polar solvent and in that the partition coefficient (log P) of the short chain amine is ?1.0 to 1.4.

  • Patent number: 9052248
    Abstract: Disclosed is a method for measuring a stable-state tension of a power transmission belt in which a temperature of an endless power transmission belt B including a belt body made of rubber in which a cord made of an organic fiber is embedded, is made higher than a glass transition temperature of the organic fiber forming the cord, with the endless power transmission belt B wound around a plurality of pulleys, and thereafter, a belt tension of the power transmission belt wound around the plurality of pulleys is measured as a stable-state tension.

  • Publication number: 20150045230
    Abstract: Provided is a reinforcing-member-equipped oxide superconducting wire in which occurrence of defects such as separation of a reinforcing member due to a decrease in the strength of an edge portion is sufficiently suppressed, problems such as separation of a reinforcing member do not occur even when a force in a thickness direction is applied, and stable superconducting properties can be maintained. The reinforcing-member-equipped oxide superconducting wire includes an oxide superconducting wire and two reinforcing members that are disposed so as to sandwich the oxide superconducting wire. The reinforcing members are bonded to the oxide superconducting wire using solder, and each of the reinforcing members has a width equal to or smaller than a width of the oxide superconducting wire or at least surfaces of the oxide superconducting wire, the surfaces facing the reinforcing members, are covered with copper, nickel, or an alloy containing at least one of these metals.
