  • Patent number: 7380543
    Abstract: In a fuel vapor release suppression system for a fuel tank, a main tank and a sub tank communicate with each other, and the sub tank and a canister communicate with each other. When the main tank has a higher temperature, fuel vapor of the main tank is supplied to the sub tank where the fuel vapor is liquefied. When the main tank has a lower temperature, fuel vapor of the sub tank is supplied to the main tank. At this time, low concentration fuel vapor is supplied from the canister to the main tank, thereby accelerating generation of fuel vapor corresponding to sub tank fuel vapor pressure, so that the sub tank fuel vapor pressure decreases. Therefore, liquefaction is accelerated in the sub tank when the main tank temperature increases. Thus, fuel vapor generated in a fuel tank is effectively liquified irrespective of ambient air temperature.

  • Publication number: 20070174381
    Abstract: The present invention provides a network connection method which prevents connection by virus-infected communication devices or communication devices intended for unauthorized access to a network, and enables connection to the network in a simple manner. A user of a requestor communication device connects to a main network by inserting a cable of the communication device to a port of a network device. When the requestor communication device is connected one-on-one to a reception box by a check-in network inside the network device, check-in is performed using the reception box. When the reception box determines through check-in processing that the requestor communication device satisfies connection qualifications, the reception box switches the network, to which the requestor communication device will be connected, from the check-in network to the main network. The requestor communication device then makes a transition to actual use of the main network.
