  • Patent number: 7817093
    Abstract: An apparatus has an antenna distance setting mechanism that sets a distance between a cosmetic cover and a radio antenna. An upper housing and a radio antenna, which has a ground and a radiating element and is movably attached to the upper housing, are covered by a cosmetic cover formed of a dielectric material. An antenna distance setting mechanism includes a radio antenna supporting member, elastic members, and protrusions. The radio antenna-supporting member is movably attached to the upper housing. When the cosmetic cover is attached to the upper housing, an inner wall of the cosmetic cover pushes the ends of the protrusions against an elastic force of the elastic members to set the distance between the radiating element and the inner wall of the cosmetic cover to a predetermined distance.

  • Publication number: 20100108162
    Abstract: A pipe coupling member for high-pressure fluid such as liquefied hydrogen includes a seal ring having a highly effective sealing function to prevent leakage of the fluid. The seal ring (72) is set in a seal ring setting space (39) defined by a second radial surface (36) and a seal ring setting surface (38) of a first tubular member (20), a forward end surface of a second tubular member (22), and the outer peripheral surface of a valve seat member (24). A forward end portion of the second tubular member (22) is provided with a communication hole (84) radially penetrating the forward end portion. The pressure of the high-pressure fluid on the downstream side of a valve seat surface (52) causes a fluid path in the second tubular member to be communicated with the sealing ring setting space (39) via the communication hole (84) and via a gap between the seal ring setting surface (38) and the outer peripheral surface of the forward end portion of the second tubular member.
