  • Publication number: 20220070142
    Abstract: A transferring device (100A) acquires address information indicating a network address of an upper network (N0) and a host address of the transferring device. The transferring device generates a subnet address which is a network address of a lower network (N1) by replacing a lower bit portion in the network address indicated in the address information with the host address indicated in the address information. The transferring device selects a host address to be assigned to a terminal device (220A) from a host address range which is based on the subnet address, and provides for the terminal device, address information indicating the subnet address and the selected host address.

  • Patent number: 10197011
    Abstract: The present embodiment improves the durability of an afterburner and yet suppresses a reduction in the engine efficiency of an aircraft engine. A ring-shaped cooling channel through which cooling air flows is formed between the outer peripheral surface of a liner and the inner peripheral surface of a rear duct. A plurality of cooling holes for blowing the cooling air along the inner peripheral surface of the liner are formed penetrating the liner. A ring-shaped annulus flame-holding member on the inner peripheral surface of the liner is provided concentrically with respect to a plurality of radial flame-holding members. The inner diameter of the annulus flame-holding member decreases in the downstream direction. The annulus flame-holding member functions as a throttle ring which throttles the flowing of a main flow of a mixed gas inside the liner.

  • Patent number: 9998351
    Abstract: When a packet to a terminal is received from a terminal, a management communication processing unit transmits by broadcasting or multicasting to a network a destination information query packet for investigating a gateway device to which the terminal is connected, receives from a gateway device a destination information response packet for notifying that the terminal is connected to the gateway device, and updates a terminal information storage table based on the destination information response packet. When the terminal information storage table is erased, the history information exchange unit transmits by broadcasting or multicasting to the network a history information query packet for requesting to re-notify of the terminal that has been notified in the destination information response packet, receives from the gateway device a history information response packet for re-notifying of the terminal, and updates the terminal information storage table based on the history information response packet.
