  • Patent number: 9704638
    Abstract: One end of a bus bar for leading an output voltage output from a switching power supply to the outside is a connection terminal connected to an output end associated with the switching power supply, while the other end is an output terminal VO. A ferrite core has a through-hole through which the bus bar is disposed. Electromagnetic coupling from the switching power supply is suppressed between the output terminal VO of the bus bar and at least a part of the ferrite core on the output terminal VO side along the bus bar. In this way, electromagnetic coupling of a part of a choke coil including the ferrite core with the bus bar penetrating therethrough on the output terminal VO side and the switching power supply is suppressed, whereby propagation of noise to the output terminal VO is suppressed.

  • 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.
