  • 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.

  • Patent number: 7102963
    Abstract: To provide a radio-wave watch, which can have an excellent appearance and can minimize the drop of the sensitivity of receiving radio waves, while suppressing the size enlargement and the cost for the contour. A radio-wave watch comprises a metallic dial having an opening, and a receiving antenna for receiving the standard radio waves containing the time data. The receiving antenna is arranged on the back of the opening of the dial and in a case at a position to confront the opening. The receiving antenna is arranged in the case at a spacing from the dial. Time lapse indicating means substantially formed of a non-metal is arranged in the case between the dial and the receiving antenna for indicating the time lapse within the range of the opening.

  • Publication number: 20040224226
    Abstract: By enhancing a sealing property of an electrochemical cell, enhancement of its long-term reliability is attempted. In the electrochemical cell in which a power generation element is sealed by an outer packaging laminated film, a sealing material is melt-bonded in an entire periphery of a predetermined portion of an outer lead terminal.
