Abstract: PURPOSE:To attain high speed communication by allowing part of transmitters acquiring an access right of a PVC to be used to send cells to a receiver through the use of a desired transmission line band thereby using fully bands of the transmission line. CONSTITUTION:Part of transmitters 2-i acquiring an access right of a PVC to be used use a desired transmission line band to send cells to a receiver 3 via an exchange switch 1. That is, the transmitter 2-i uses an access right acquisition deciding means 6-i to decide whether or not the access right of the PVC to be used is acquired and when the acquired access right is decided, a cell transmission means 7-i uses a desired transmission line band to send cells to the receiver 3. Furthermore, a message representing the access right is circulated among the plural transmitters 2-i and the access right of the PVC to be used is acquired by allowing the transmitter 2-i to receive this message. Furthermore, a PVC management means 5 gives sequentially the access right to the transmitter 2-i.

IPC: B21D51/26
Filed: 1995-02-24
Abstract: PURPOSE: To secure workability with a thin thickness by using a steel sheet with which, as a can body, a specific length of a diameter reducing part in the height direction is provided with a recrystallized structure in the whole circumference and is softer than the non-reducing part excluded for heat treat ment. CONSTITUTION: In order to prevent wrinkles in working for reduction and cracks in forming a flange, it is essential that the whole circumference of a can is heat treated at least for 10% or more in the length for reduction including the flange part in the height direction of the can and that the steel is recrystallized so as to recover its workability. As the extent of the heat treatment, heating is necessary at the recrystallizing temperature or above of the steel, namely at 550 deg.C or above. As the heating atmosphere, an inactive atmosphere is required in order to prevent discoloration due to oxidation. The heat treatment thus performed can bring out a can body having a crystallized structure with such a superior ductility as the reducing part including the flange forming part is recrystallized for 10 to 130% in the length percentage.
