  • Packet routing apparatus and a method of communicating a packet
    Patent number: 7639604
    Abstract: When any communication port receives a packet from a network, it transmits the packet to a relay processing section. The relay processing section identifies a relay processing section of a transfer destination according to destination information included in the packet to transmit the packet to a packet switch section. When the relay processing section of the transfer destination is a working relay processing section, the packet switch section transfers the packet to the working relay processing section and a protection relay processing section.

  • Rotary heat exchange apparatus provided with a spherically coiled heat transfer tube
    Patent number: 4377202
    Abstract: A rotary heat exchanger characterized in that a spherically coiled heat transfer bypass tube is provided concentrically about a reflux type heat transfer double-tube at a part thereof, the outer tube of the double tube being rotatable, wherein a suction tube is provided around the outer tube within the spherical space defined by the bypass tube, said suction tube incasing screw vanes secured to the outer periphery of the outer tube, whereby convection is induced within the spherical space by the rotation of the outer tube. With the exchanger, good heat exchange efficiency is attainable without scaling.
