    • A pipe coupling comprises a cylindrical coupling member fabricated of shape memory alloy and a foil as a metallic member of low melting point attached to an internal surface of the cylindrical coupling member, a melting point of the foil being lower than that of materials of a pipe to be joined to the pipe coupling and of the coupling member. Further, a pipe coupling comprises a cylindrical coupling member fabricated of shape memory alloy, at least two pieces of ring protrusions formed on an internal surface of the cylindrical coupling member, and metallic member of low melting point which is attached to an internal surface of the cylindrical coupling member between the ring protrusions, a melting point of the metallic member of low melting point being lower than that of materials of a pipe to be joined and of the coupling member. Furthermore, a pipe coupling comprises a cylindrical coupling member fabricated of shape memory alloy, a ring stopper formed at a central portion of the cylindrical coupling member in the axial direction thereof, and metallic member of low melting point attached to an internal surface of the cylindrical coupling member on both sides of the ring stopper, a melting point of the metallic member of low melting point being lower than that of materials of a pipe to be joined and of the coupling member.

    • Communication is performed without paying attention to the fact that the communication is executed between multimedia terminals having communication procedures differing from each other.A terminal 2 starts a communication procedure that is necessary to establish a communication path to a communication service unit 1, in order to execute communication with a multimedia terminal 3; when a communication protocol conversion unit 7 receives communication start request from the terminal 2, the communication service unit executes identification process of a calling terminal based on the identification number, which exists in communication start request, for determining the multimedia terminal 2, and inquires a terminal information managing unit 9 of the calling terminal. The terminal information managing unit 9 retrieves terminal information related to the calling terminal based on a terminal information request, and informs of the retrieved terminal information to the communication protocol conversion unit 7. The communication protocol conversion unit 7 informs of the communication start request to the terminal 3 when the transmitting the terminal information of the terminal 2 is obtained, and continues a relay process in communication procedure, which is necessary for following establishment of a communication path.
    • 执行通信,而不用注意在具有彼此不同的通信过程的多媒体终端之间执行通信的事实。 终端2开始建立到通信服务单元1的通信路径所需的通信过程,以便执行与多媒体终端3的通信; 当通信协议转换单元7从终端2接收到通信开始请求时,通信服务单元基于存在于通信开始请求中的识别号码执行主叫终端的识别处理,以确定多媒体终端2,并且向 主叫终端的终端信息管理部9。 终端信息管理单元9基于终端信息请求检索与主叫终端相关的终端信息,并将所检索到的终端信息通知给通信协议转换单元7。 当发送终端2的终端信息时,通信协议转换单元7向终端3通知通信开始请求,并且继续通信过程中的中继处理,这对于跟随建立通信路径是必需的。
