摘要： In a communication system that includes a control station and dependent stations, the control station broadcasts data intended for the dependent stations on a per-superframe basis. The dependent stations relay the data received from the control station among themselves. If a dependent station has received the data transmitted from the control station, the dependent station transmits an acknowledgement response. If a dependent station does not receive an acknowledgement response from another dependent station, then the dependent station relays the data intended for the other dependent station.

Said stabilizer is preferably blended in such a manner that said (A) is contained in an amount of 0.01 to 10 parts by weight based on 100 parts by weight of a thermoplastic polymer (polycarbonate or the like), and said (B) is contained in an amount of 0.01 to 1 part by weight based on 100 parts by weight of said (A). When the thermoplastic polymer is subjected to gamma-ray irradiation, said stabilizer can efficiently protect the thermoplastic polymer from the deterioration of physical properties and yellowing; and on molding processing, the stabilizer-added polymer is suffered from little color tone deterioration and has excellent color tone, and at the same time, the polymer is scarcely suffered from molecular weight decrease on molding, and exhibits excellent thermal stability, moldability or the like. The thermoplastic polymer (especially polycarbonate) composition containing said stabilizer thus obtained is suitable for medical apparatus and medical material uses, especially a jacket case for an artificial dialyzer.

摘要： A multiple control station transits a first broadcast frame including a first identifier for identifying a first host and a second broadcast frame including a second identifier for identifying a second host to a terminal station over a wireless channel using time division. The multiple control station then receives a connection request frame that requests connection with the first host or the second host from the terminal station. Arbitration is then performed so that the terminal station is connected to the first host or the second host in accordance with the first identifier or the second identifier included in the received connection request frame.

摘要： There is provided a communication control technique in which it is possible to avoid interference with another wireless communication system. This invention is characterized by a control station which controls wireless communication of dependent stations. When a dependent station newly starts, the control station determines whether a beacon transmitted by the dependent station is received by another wireless communication network. When determining that the beacon is received by the other wireless communication network, the control station instructs the dependent station to lower the transmission power until the beacon is not received.

摘要： A communication system makes throughput preferable by reducing wireless frame collision which occurs when a plurality of control stations cannot recognize one another. When a wireless communication device that is operating as a dependent station of a first control station detects a second control station, DEVice operates as a dependent control station. Accordingly, the second control station is changed to a dependent station or a dependent control station.
