  • Patent number: 7926509
    Abstract: Disclosed is a method of controlling the flow rate of clustering fluid using a pressure type flow rate control device in which the flow rate Q of gas passing through an orifice is computed as K=KP1 (where K is a constant) with the gas being in a state where the ratio P2/P1 between the gas pressure P1 on the upstream side of the orifice and the gas pressure P2 on the downstream side of the orifice is held at a value not higher than the critical pressure ratio of the gas wherein the association of molecules is dissociated either by heating the pressure type flow rate control device to the temperature higher than 40° C., or by applying the diluting gas to the clustering fluid to make it lower than a partial pressure so the clustering fluid is permitted to pass through the orifice in a monomolecular state.

  • Publication number: 20080101583
    Abstract: An LSP control unit checks whether or not there is a label switching path of a hundred to thousand times of a band necessary for transferring a VoIP packet between a pair of edge label switch routers in response to notification from a VoIP packet control unit. When there is not a label switching path between the edge label switch routers, the LSP control units establishes a label switching path between the pair of edge label switch routers. When there is a label switching path between the edge label switch routers, the LSP control units checks whether or not it is possible to ensure a band necessary for transferring the VoIP packet in the label switching path. When it is not possible to ensure a band necessary for transferring the VoIP packet in the label switching path, a label switching path is established between the pair of edge label switch routers. This label switching path has a band of a hundred to a thousand times of a band necessary for transferring the VoIP packet.
