  • Patent number: 10834662
    Abstract: A communication system is provided which includes: a portable terminal; a mobility management device that manages mobility of the portable terminal; a first gateway that connects the portable terminal to a first network; and a second gateway that connects the portable terminal to a second network. Based on a result of determining whether to connect the portable terminal to the first network via the first gateway or connect the portable terminal to the second network via the second gateway, the mobility management device switches between causing the portable terminal to use first contract information for connection to the first network via the first gateway and causing the portable terminal to use second contract information for connection to the second network via the second gateway.

  • Patent number: 9618033
    Abstract: A remote control device is provided, which includes a control cable. The control cable includes a reinforcing wire 11 of which the both ends are fixed by anchors 14, 14, an outer casing 12 made of synthetic resin so as to be slidable to the reinforcing cable, and so as not to constrain the thermal deformation in the axial direction based on the variation of ambient temperature, and an inner cable 13 made of metal having flexibility housed in the outer casing 12 slidably. In the both ends of the inner cable, cable ends 17, 17 coupled to an operating member and an operated member are firmly fixed.

  • Patent number: 8534895
    Abstract: A light emitting device comprises: a light guiding plate including two facing principal surfaces and circumferential end surfaces connecting the principal surfaces; and a point-like light source facing at least one surface of the circumferential end surfaces of the light guiding plate. One surface of the circumferential end surfaces except the surface where the light source is arranged is a light emitting surface, the thickness of the light guiding plate facing the light source is smaller than the thickness of a portion constituting the light emitting surface and is smaller than the thickness of a light emitting surface of the light source, a diffusing unit is formed on at least one of the principal surfaces; and a reflection member covering peripheries of the light source and the light guiding plate except portions constituting the light emitting surfaces of the light source and the light guiding plate is provided.
