  • Patent number: 8962129
    Abstract: A rubber-reinforcing cord (12) as a rubber-reinforcing member of the present invention is a rubber-reinforcing member for reinforcing a rubber product (such as a toothed belt (1)). The rubber-reinforcing cord (12) includes a reinforcing fiber or a reinforcing fiber sheet, and a first coating film provided on a surface of the reinforcing fiber or a surface of the reinforcing fiber sheet. The first coating film is formed by applying a first treatment agent containing polyvinyl alcohol and a crosslinking agent to the reinforcing fiber or the reinforcing fiber sheet and drying the first treatment agent. In the reinforcing member of the present invention, a second coating film as a primary coating film may be provided on the surface of the reinforcing fiber or the surface of the reinforcing fiber sheet. The second coating film can be produced using a second treatment agent containing a rubber latex, for example.

  • Patent number: 7674400
    Abstract: The present invention provides a light-emitting body in which fine phosphor particles are dispersed in an oxide matrix, with the fine phosphor particles containing at least one selected from oxides and oxysulfides as a parent material. When this light-emitting body is dispersed in a resin, a resin composition having excellent transparency can be obtained. This light-emitting body can be produced by: preparing a gel through a sol-gel process in which a raw material solution containing a compound that supplies metal atoms composing the fine phosphor particles is used; and heating the gel at 400° C. or higher, for example. Preferably, the light-emitting body has a shape of a flake or fiber.
