  • Publication number: 20110086976
    Abstract: The present invention relates to sliding parts, precision parts and timepieces and electronic equipment using those parts. Sliding parts are composed by a resin in which the degree of orientation of a fibrous filler is higher at the portion serving as the sliding surface than inside the sliding part, and the fibrous filler is oriented along the sliding surface on the sliding surface. Alternatively, precision parts are composed by a resin to which has been added carbon fibers for which a carbon compound is thermally decomposed to carbon in the vapor phase and simultaneously grown directly into fibers simultaneous to this thermal decomposition. Moreover, timepieces and electronic equipment are composed by these sliding parts or these precision parts.
