    摘要： In a method for producing PLZT powder, the A-site components are co-precipitated simultaneously and mixed with the B-site components which are also co-precipitated simultaneously. As a result, the powder obtained by calcination of the precipitates has less fluctuation in the chemical composition compared with the prior art.

    摘要： Disclosed is a ceramic composite consisting essentially of hexagonal boron nitride (h-BN), aluminum nitride and, if any, unavoidably formed aluminum oxynitride (AlON), and a sintering aid and/or a reaction product of the sintering aid with the above-mentioned components (h-BN, AlN and AlON), in which the total amount of the sintering aid and the reaction product is 0.01 to 5 parts by weight per 100 parts by weight of the sum of h-BN, AlN and AlON. This sintered body comprises AlN and AlON in a total amount of 45 to 5% by weight with 55 to 95% by weight of h-BN. Alternatively, this sintered body comprises AlN and AlON in a total amount of 80 to 5% by weight with 20 to 95% by weight of h-BN, the degree of anisotropy of the thermal conductivity of the sintered body (the ratio of the maximum thermal conductivity to the minimum thermal conductivity, the direction of the maximum thermal conductivity being perpendicular to the direction of the minimum thermal conductivity) being at least 2.

    摘要： A wireless communication system includes a transmission device including plural transmission antennas and a receiving device including plural reception antennas. The transmission device includes a branching unit that branches a signal into plural transmission signals respectively passing plural signal lines each corresponding to each of the transmission antennas and delay units provided on at least one of the signal lines to apply a delay to the transmission signal. When a transmission signal branched by the branching unit is applied with a delay by the delay units, the transmission device sets the transmission signal on which the delay is applied as the transmission signal, and transmits the transmission signals to the receiving device via the transmission antennas. The receiving device includes delay units provided on at least one of plural signal lines that respectively pass plural reception signals received at the reception antennas to apply a delay to the reception signal and a combining unit that sets the reception signal on which the delay is applied as the reception signal, and combines the reception signals.
