    • The disclosed invention makes mobile terminals physically impossible to use in specific spaces without using radio waves of so high intensity as to affect medical devices and without requiring telephone companies that operate wireless communications systems (WCS) to take special measures. Cooperation of a telephone company on the implementation of making mobile terminals physically impossible to use in specific spaces makes mobile terminals provided by the telephone company easy to use. Pseudo signals of downlink pilot signal in WCS are emitted off the pilot timing in specific spaces. Uplink channel radio waves in cooperative telephone compannies' WCS are relayed and communication path is disconnected if the uplink channel radio waves are for communication of an attribute banned in the space. Communication path can be disconnected without increasing the intensity of radio waves so high. In cooperative telephone compannies' WCS, only the path of communication of an attribute banned in the space is disconnected.
    • 所公开的发明使得移动终端在特定空间中物理上不可能使用,而不使用如此高的强度的无线电波影响医疗设备,并且不需要操作无线通信系统(WCS)的电话公司采取特殊措施。 电话公司在实施移动终端实际上​​不可能在特定空间中使用的合作使得电话公司提供的移动终端易于使用。 WCS中的下行链路导频信号的伪信号在特定空间内从导频定时发出。 如果上行链路信道无线电波用于在空间中禁止的属性的通信,则中继合作电话单元WCS中的上行链路无线电波,并且通信路径被断开。 通信路径可以在不增加无线电波强度的情况下断开连接。 在合作电话公司的WCS中,只有空间中禁止的属性的通信路径才会断开连接。

    • A logic circuit for use as a selector having multiple inputs and high operation speed. The logic circuit includes a first FET having a first electrode connected to a first power supply, a second electrode connected to an output terminal and a third electrode connected to an intermediate control node, and a plurality of logic blocks parallelly connected between the second power supply and the output terminal. Each logic block includes second and third FETs being of a conductivity type opposite to that of the first FET and connected in series between the output terminal and a second power supply. Each logic block also includes a fourth FET being of the same conductivity type as the second and third FETs and having a third electrode connected to the third electrode of the second FET, a first electrode connected to the third electrode of the third FET and a second electrode connected to the intermediate control node. The conduction resistance between the output terminal and the first power supply is reduced and the parasitic capacitance added to the output terminal is also reduced, thereby allowing the logic circuit to be operated at high speed.
