  • Publication number: 20120069852
    Abstract: The network system includes a controller (10) and a plurality of terminals (20). The controller (10) sends a first request signal (41) which indicates a first limited time period defining a range within which the controller (10) receives signals respectively from the terminals (20) of which the number is identical to the maximum number of the terminals (20). Upon receiving the first request signal (41), the terminal (20) sends a first response signal (51) within the first limited time period. The controller (10) determines a total number of the terminals (20) on the basis of the number of the first response signals (51) received within the first limited time period, thereby determining a second limited time period defining a range within which the controller (10) receives signals respectively from the terminals (20) of which the number is identical to the total number of the terminals (20). The controller (10) sends the second request signal (42) which indicates the second limited time period.

  • Patent number: 8128741
    Abstract: A dissolving apparatus has a cylindrical tubular container closed at both ends with its center axis being inclined to the horizon. A center of an interface between a gas and a liquid in the container is positioned at a center in a lengthwise direction of a side wall of the container. Two inner spaces of the container above and below the interface are referred to as a gas section and a liquid section. An injection inlet for injecting a gas-liquid mixed fluid into the container is provided at a level corresponding to, or lower than, the interface. A liquid outlet for discharging the liquid is provided near a bottom of the liquid section of the container. Since the container is inclined, the interface can have an area large enough to promote dissolution of the gas into the liquid. Since the depth of the liquid in the liquid section is sufficiently deep, the liquid can be prevented from being discharged through the liquid outlet with large gas bubbles being present therein.
