Abstract: PURPOSE:To provide a communication controller which simplifies procedures of entry to a system at the time of setting plural multi-point to multi-point connections between plural terminals like a computer aided group work system. CONSTITUTION:A user information processing part 101 selects a group set by a group setting part 13 and sends a connection set instruction signal to a connection setting part 19, and this part 19 generates a correspondence table between group discrimination information and connection discrimination information in accordance with this connection set instruction; and when the user information processing part 101 transmits data, transmission user information is outputted to a destination header generating part 12, and a signal to designate the group as the transmission destination is outputted to the group setting part 13, and user information is broadcasted to only communication terminals belonging to this group.

Abstract: PURPOSE:To provide an oxide superconductive wire material of excellent perfor mance by forming a metallic outer peripheral coating body of Ag or Ag-M alloy (wherein M is at least one kind selected from Au, Pd, Pt) as a main component and of an Ag group alloy containing specific weight % of at least one kind selected from Mg, Al, Si, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Nb, Cd, In, Sn. CONSTITUTION:Respective powder of Bi2O3, PbO, SrCO3, CaCO3 CuO is mixed with each other at a mol ratio of 0.9 : 0.3 : 2 : 2 : 3, heat treated for 24 hours at, for example, 800 deg.C, and pulverized in a ball mill to obtain a calcination. On the other hand, Mg is added to pure Ag, melted to obtain a rod, then cast, heat treated at a specified temperature in the Ar atmosphere, and subjected to cutting work to obtain an alloy made pipe of 1 weight % Ag having, for example, 6mm outer diameter and 4mm inner diameter. In this wire material, 0.2% proof stress of, for example, 20 kg/mm or larger, a sufficient elongation characteristic and a high critical current density can be obtained, and characteristic deterioration due to stress and strain is not generated.

Abstract: PURPOSE:To enable the communication between information equipments only if information equipments are brought by transmitting and receiving communication terminal discrimination information and defining the communicable communication terminals discriminated based on received communication terminal discrimination information as the same group. CONSTITUTION:The communication terminal discrimination information generation part 11 of a communication control part 102 generates communication terminal discrimination information and periodically transmits the information from an antenna 31 via a radio transmission/reception part 103. The communicable terminal discrimination part 14 of the radio transmission/reception part 103 discriminates communicable communication terminals by the communication terminal discrimination information which is received by an antenna 31 and is transmitted from other communication terminal. A group setting part 13 sets the discriminated communicable communication terminals as the same group and a destination header part 12 performs communication with the only other communication terminals within the set same group. Therefore, only if communication terminals approach with each other, communication becomes possible, and a logical communication link with a desired opposite party can be extremely easily set anywhere.
