摘要： Communication time period measuring frames are simultaneously sent from an OAM adaptive device on a transmission side, to both a working path and a protection path. In an OAM adaptive device on a reception side, reception times of the frames having arrived from both the paths are checked so as to measure a time period difference between both the paths. The time period difference is fed back to a logic distance adjustment function of each PON section to determine required communication time periods of the PON sections respectively included in a working system and a protection system. Communication time periods of the working system and the protection system in a packet communication network are arbitrated in order to decrease a packet loss at line switching in a packet relaying network.

摘要： A communication system is provided which allows synchronous devices in different synchronous communication networks to have synchronous communications with one another via an asynchronous communication network. In the communication system of the present invention, a master communication device generates a master clock based on a reference clock which is provided by a clock supplier. The master communication device sends a synchronization information frame, which contains information about the generated master clock, to plural slave communication devices via the asynchronous communication network. The slave communication devices each reproduce the master clock from the received synchronization information frame.

摘要： The invention provides a welding method by resistance welding capable of adequately increasing a welding strength between two conductive terminals each made of copper, and a conductive terminal structure obtained by the method. A first conductive terminal made of a tinned flat copper plate is molded such that a step portion is formed at a position spaced away from a tip end position of the first conductive terminal and a projection is formed at a tip end portion ranging from the tip end position to the step portion. A second conductive terminal made of the aforementioned copper plate and the first conductive terminal are molded such that a weld surface of the second conductive terminal has a size to cover an entire weld surface of the projection of the first conductive terminal. Simultaneously, the respective conductive terminals are molded such that the tip end portion of the first conductive terminal becomes substantially equal in sectional area to a weld portion of the second conductive terminal. These conductive terminals are brought into contact under pressure with electrodes equal in electrical characteristic to each other, and then electric current is fed to the electrodes. Thus, the projection of the first conductive terminal is melted into and is welded to the weld surface of the second conductive terminal.
