  • Publication number: 20020116446
    Abstract: In a network system S, which includes an agent server LS that is located between the Internet IN and a terminal T and that relays a connection request from the terminal T to the Internet IN, the agent server LS requests the establishment of a connection between the terminal T and the agent server LS and transmits to the terminal T a request signal that includes identification information for the agent server LS. The terminal T receives the request signal and examines the agent server LS based on the identification information included in the received signal. When it is concluded that the agent server LS that transmitted the request signal is one to which the terminal T should be connected, a connection is established with the agent module LS that transmitted the request signal.

  • Publication number: 20020057180
    Abstract: An amorphous metal core transformer is provided with a plurality of wound magnetic cores composed of amorphous metal strips, and a plurality of coils, each of the coils including a primary coil and a secondary coil, each of the coils further including a bobbin. The primary coil employs different material from that of the secondary coil, e.g., a copper conductor is employed in a primary coil, while an aluminum conductor is employed in a secondary coil. The bobbin has higher strength than that of the amorphous metal strips.

  • Patent number: 6005468
    Abstract: An amorphous transformer prevents deformation or deflection caused by the repulsion force between an outer coil and an inner coil and prevents formation of a one-turn-current through a reinforcement member and a coil frame. The amorphous transformer includes amorphous cores, an outer coil and an inner coil, a coil frame and a reinforcement member. The reinforcement member prevents the amorphous core from being deformed inward by the electromagnetic force of the coil, and the frame member and the reinforcement member prevents formation of an electrical closed-loop. Accordingly, the amorphous transformer core is protected from being damaged.
