  • Publication number: 20240125515
    Abstract: The purpose of the present invention is to provide a control device, a heat source system, a control method, and a control program with which a heat medium at a required temperature can be more effectively sent out. This control device, which is applied to a heat source system 1 comprising a plurality of heat source machines (2a), (2b) connected in series, comprises a setting unit which sets the outlet setting temperatures of cool water in the respective heat source machines (2a), (2b) on the basis of: a measured value of a cool water flow rate, measured values of inlet temperatures of the cool water in the respective heat source machines (2a), (2b); and the required outlet temperature of the cool water in the heat source system (1).

  • Patent number: 6892078
    Abstract: A SIM card mounting structure of a mobile phone includes a SIM card receiving recess 5 provided in a rear surface portion of a front side casing of the mobile phone for fittingly receiving a SIM card 1 therein, a pressing portion 3 formed of an elastic material and having one end integrally formed with the rear surface portion of the front side casing and the other end positioned over the SIM card receiving recess to elastically press the SIM card 1 and electrode terminals 2 for connecting electrodes of the SIM card 1 to a battery. The electrode terminals 2 are formed of an elastic material and arranged on a bottom of the recess 5 in an opposing relation to electrodes of the SIM card 1. The one end of the pressing portion is formed integrally on an end portion of the SIM card receiving recess 5 in a longitudinal direction of the mobile phone such that the pressing portion functions as a longitudinal leaf spring.

  • Publication number: 20040091267
    Abstract: A mobile phone includes a light emitting section and a flat space section in a case thereof. In the surface of the case, the mobile phone includes a window section through which light emitted from the light emitting section is transmitted. The light emitting section includes a light emitting surface directed in a direction along a surface of a wiring board located in the case, and emits light to the space section. When light beams of three colors, red, green, and blue, are emitted from the light emitting section, the light beams are mixed in the space section and emitted-through the window section to the outside of the case. This mobile phone can be made thinner and can emit light with high uniform luminance from the window section.

  • Patent number: 6707430
    Abstract: A structure for supporting an antenna is composed of an antenna-supporting member which is formed under a radiator and shaped into a cylinder, an antenna-inserting portion which includes the first cylindrical space for accommodating the antenna-supporting member, locking claws which are connected with a lower end of the antenna-supporting member and interlocked with a lower edge of an inner wall of the first cylindrical space, and a rubber bush which includes a through hole, through which the antenna-supporting member passes, and is inserted between the radiator and the antenna-supporting member. An upper part of the antenna-inserting portion includes the second cylindrical space, which is concentric with the first cylindrical space and has an internal diameter larger than that of the first cylindrical space, and a lower part of the rubber bush fits into the second cylindrical space.
