摘要： A wireless communication apparatus that conducts full-duplex wireless communication with a communication partner using a transmitting antenna and a receiving antenna is provided. The apparatus includes a transmitting unit configured to transmit a signal via the transmitting antenna using a first frequency channel, a receiving unit configured to receive a signal via the receiving antenna using a second frequency channel different from the first frequency channel, and a control unit configured to control beam angle of directionality of at least one of the transmitting antenna and the receiving antenna, so that a direction of a communication path of a signal which the transmitting unit transmits and the communication partner receives, and a direction of a communication path of a signal which the communication partner transmits and the receiving unit receives, differ from each other.

摘要： A new gamma-ray stabilizer comprising a combination of 100 parts by weight of a benzyl compound (A) having a specific chemical structure and 0.01 to 10 parts by weight of a pentaerythritol phosphorous ester (B) having a spirocyclic structure. 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 spread spectrum receiving apparatus comprises: a reproducing circuit to reproduce a carrier signal from a reception signal and a diffusion code; a demodulation circuit to demodulate the reception signal into a base band signal on the basis of the carrier signal reproduced by the reproducing circuit; and a judgment circuit to judge the reception data from the base band signal from the demodulation circuit. The reproducing circuit has an operation circuit to arithmetically operate the reception signal and the diffusion code and a detection circuit to detect a difference between the phases of an output of the operation circuit and an output of an oscillator. The oscillator oscillates at a carrier frequency in accordance with a phase difference detected by the detecting circuit.
