    摘要: An automatic changeover method of communication networks includes steps (a) to (d). In the step (a), a first station communicates with a second station through a first wireless communication network. In the step (b), the first station measures a first level fluctuation value more than once, wherein the first level fluctuation value indicates a fluctuation degree of electric field intensity of an electromagnetic wave received from the first wireless communication network. In the step (c), the first station calculates a first average level fluctuation value, wherein the first average level fluctuation value is an average of a plurality of the first level fluctuation values. In the step (d), the first station changes over from the first wireless communication network to a second wireless communication network based on the first average level fluctuation value. The first wireless communication network may be a network for a wireless LAN (Local Area Network), and the second wireless communication network may be a network for a PHS (personal Handyphone System).

    摘要: A taste recognizing device has a sensor body and a touch panel. The sensor body includes a sensor part with a sensor probe for measuring taste by means of a molecular film which outputs an electrical signal presenting taste information representing at least one kind of taste, a solution insertion part having insertion sections which are arranged circumferentially at predetermined intervals and in which a solution whose taste is to be measured, a reference taste measurement solution and a cleaning solution are selectively inserted, and an arm drive part for moving the sensor part relative to a predetermined insertion section of the solution insertion part. On the basis of the electric signal outputted from the sensor probe and presenting the taste information, at least measurement for taste recognition of the solution whose taste is to be measured is made possible. The touch panel is structured so that all the items of the operations of the sensor body necessary for measurement for the taste recognition are indicated by buttons for each function and displayed in order on the screen, the operation item corresponding to the operation item is inputted when the user clicks a predetermined button, and thereby all the operations of the sensor body by the user are performed with reference to the display on the screen. With this, the taste recognizing device enables easy taste measurement of the substance whose taste is to be measured by easier operation as a whole.

    摘要: An electricity controller is provided which comprises a first power control means for controlling output power from power generator 4 to a first level during a first period of start-up time for feeding, a second power control means for controlling output power from power generator 4 to a second level lower than first level during a second period after the first period, and a third power control means for controlling output power from power generator 4 to a third level greater than the second level and lower than the first level during a third period after the second period. A discharge tube 2 is heated during the first period for supplying a large amount of electric power to discharge tube 2 to elevate the tube temperature and thereby uniformly disperse mercury vapor in discharge tube 2. Subsequently, while the device maintains the tube at a relatively high temperature during the second period for supplying a small amount of electric power to discharge tube, it can effectively reduce and restrict the release amount of infrared ray from discharge tube 2 in order to enable a remote controller 8 to control a display device immediately after the indication.

    摘要: An adaptor serving for both a mobile phone unit and a private IP telephone unit is disclosed. A mobile phone unit is connected to the adaptor through a low power wireless system or a wired cable. A telephone unit controller manages resource data (data such as telephone directory, telephone history, and mail). A memory editor links a telephone directory of a mobile phone unit and a telephone directory of an IP-PBX in cooperation with a telephone directory controller of the IP-PBX. A VoIP extension line section provides the mobile phone unit with a function of an extension telephone unit in cooperation with the IP-PBX. A QoS controller is a circuit that performs control for minimizing loss of audio data due to communication congestion on a communication path (intranet/Internet). A charging circuit is a circuit that charges a battery of the mobile phone unit. The charging circuit contains a protecting circuit that protects the battery from being overcharged.

    摘要: If a PHS wireless LAN combo is constituted in which a PHS base station and a wireless LAN base station are placed in the same case, their frequency bands are different but they interfere with each other due to an influence of higher harmonics, which decreases communication efficiency. When a PHS base station is in a transmitting state and a wireless LAN base station is in a receiving state, a transmission signal from the PHS base station is multiplied by a predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the wireless LAN base station, and when the wireless LAN base station is in a transmitting state and the PHS base station is in a receiving state, a transmission signal from the wireless LAN base station is multiplied by the predetermined attenuation ratio so as to subtract an attenuated value from a received signal of the PHS base station.
