Abstract: A wireless communication device includes an antenna section configured to be provided with a plurality of antenna units that transmit and receive n communication signals having different directivities, a multiplexer configured to be connected to the antenna section, and n signal transmitting and receiving units configured to be connected to the multiplexer, to generate transmission signals, to demodulate reception signals, and to be provided corresponding to the n communication signals. The multiplexer switches connections between the antenna section and the n signal transmitting and receiving units in a time-division manner in a sampling period shorter than a period of a symbol of each of n reception signals to sequentially sample the n reception signals for each of the directivities at a time of reception. The antenna section sequentially receives divided reception signals obtained by dividing the reception signal corresponding to the directivity in the sampling period. Each of the signal transmitting and receiving units individually demodulates the reception signal corresponding to the divided reception signals that correspond to the directivity of the signal transmitting and receiving unit and have been sequentially acquired at a timing of the connection to the multiplexer.

Abstract: Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al2O3 having a specific surface area of 5 m2/g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al2O3; and a third step for performing a reduction process on the 12CaO·7Al2O3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.
