Abstract: PURPOSE: To provide a rare earth element permanent magnet which has superior magnetic characteristics and machinability inexpensively by adding suitably transition elements to Sm-Co-Cu-Fe magnet, heat treating and pulverizing the magnetic compound, and forming the powder having particle size of special diameter or higher.  
     CONSTITUTION: An ingot of alloy of inter-metal compound RM of rare earth elements R and transition metal M (a mixture of one or more metals) having a formula I in composition (where M represents one or more of transition metals except for Co, Cu and Fe) is heated treated and pulverized into powder in a manner that the grain size of the powder thus pulverized is higher than 15μ in its content of more than 50%. The powder is molded by a binder. As a result, since transition metal M is added to the R-Co-Cu-Fe magnet, the magnet can incorporate high coercive force. When the content ratios of the transition metals u, v, w and z are limited, it can provide the best magnetic characteristics. Since it incorporates the binder, it has superior machinability. When the grain size of the powder is liminted, it can enhance its saturable magnetization.

Abstract: PURPOSE:To reduce a load on a central processor, by attaching a tag which represents the physical address of a signal controller by every signal controller at a transfer opposite, on an outgoing packet. CONSTITUTION:When the incoming of a packet using a D-channel is inputted to a packet processing function device PSM14, a central processor CSCP15 teaches device numbers PA1-PA3 of the signal controllers that become paths to incoming data terminals to the PSM14 through a control bus. Local processors LCP12 on the output and input sides of a time division switch TDSW11 transfers the packet autonomously to a line module LM13 using the numbers PA2 and PA1. The LM13 sends the packet to a TA group belonging to a designated physical address using an IEI=127(broadcasting form), and a SPAI=16(packet). In this way, it is enough for the central processor to perform a process to indicate the physical address to a signal transfer device where an incoming terminal is accommodated, to the packet processor.
