    摘要: Received signal strength detecting means 109 and 110 detect received signal strength of the antennas of the respective terminals. A transmission antenna selector 111 selects an antenna with a maximum received signal strength with respect to the respective communication destinations, and when there is a plurality of communication destinations having the same antenna with a maximum received signal strength, the transmission antenna selector selects transmission antennas to be different from each other based on the received signal strength of the antennas with the second largest received signal strength, and an internal switch of a transmission antenna change device 114 is changed based on the selection result. This eliminates the need for providing mixers without reducing transmission diversity effect, and results in a reduction of a maximum output of a transmission amplifier.

    摘要: Disclosed is a method of joining metallic members together. The metallic members are coated with an undercoat composed of an alloy of tin and zinc and contacted with each other through a mixture containing a solder comprising tin and zinc and a flux, while heating the metallic members to melt the solder. Then the molten solder is solidified to join the metallic members. Here, the ratio of zinc in the undercoat is represented by x (% by weight), the ratio of zinc in the solder is represented by y (% by weight), and the ratio, x, and the ratio, y, are values within an area enclosed by the line A or B in FIG. 1, which satisfies the formulas: 1≦x≦20, 3≦y≦13 and 3≦(x+y)/2≦13, or formulas: 0.1≦x≦25, 2≦y≦15 and 2≦(x+y)/2≦15.

    摘要: The present invention provides a simple and inexpensive method for producing &agr;-hydroxy-&bgr;-aminocarboxylic acids and their esters. An ester of an N-protected &agr;-amino acid ester is converted into a &bgr;-ketosulfoxide, which is then processed with an acid to give an &agr;-ketohemimercaptal. Next, this is acylated and then processed with a base to obtain an N-protected &agr;-acyloxy-&bgr;-amino-thioester, which is then saponified to obtain an intended compound. According to the method of the present invention, it is possible to produce &agr;-hydroxy-&bgr;-aminocarboxylic acid derivatives, which are intermediates in producing various HIV protease inhibitors, renin inhibitors and carcinostatics, from a-amino acids. The method comprises reduced reaction steps, the selectivity in the method to give the intended product is high, and the yield of the product obtained is high.
