    • A novel dipeptide compound inhibiting the enzymatic activity of HIV protease and an anti-AIDS medicine comprising this dipeptide compound as an effective component represented by formula (I) wherein R1, R2, and R3 independently represent C1-4 alkyl, alkoxyl, hydrogen etc . . . (provided that not all of the R1, R2, and R3 are hydrogen), R2 and R3 may form a ring together, R4 represents C1-4 alkyl or hydrogen; X is a methylene group or a sulfur atom; Y represents e.g., a five or six member monocycle or aryloxyalkyl having up to 12 carbon atoms (provided that the aromatic ring may be substituted by alkyl etc . . . ); and Z represents a C1-6 aliphatic hydrocarbon or an aromatic hydrocarbon having up to 12 carbon atoms (provided that this aromatic ring may be substituted by alkyl etc . . . , or at least one carbon atom in the aromatic hydrocarbon may be replaced by a hereto atom).

    • A mobile telephone apparatus operates as follow: when an origination signal is transmitted from the mobile station, the base station of a wireless zone where the mobile station is not present communicates a connection possible signal to the base station in the zone where the mobile station is present, and the base station having a larger number of idle channels than that of the other base station is selected on priority basis independent on the signal intensity. Therefore, when the origination signal from the mobile station is received by a plurality of base stations, the base station having the receiving level larger than the required minimum receiving level and having the maximum number of idle channels is selected, and it is possible to reduce the origination loss rate relative to the conventional system.
    • 移动电话装置的动作如下:当从移动台发送起始信号时,移动台不存在的无线区域的基站在移动站所在的区域向基站发送连接可能信号 存在,并且优先基于信号强度优先选择具有比另一个基站的空闲信道数更多的基站的基站。 因此,当多个基站接收到来自移动台的始发信号时,选择具有大于所需最小接收电平并且具有最大空闲信道数的接收电平的基站,并且可以减少 相对于传统系统的起始损失率。
