    • Disclosed is a transmission power control method which enables communications between a base station and a terminal station to be always performed at a high transfer rate by always assuring an uplink communication path between a base station which can transfer a downlink signal most efficiently and a terminal station. Each of terminal stations 111 to 119 selects a base station which can receive a downlink radio wave with the highest power, and transmits a code for identifying the base station on an uplink signal. When the received power of the uplink radio waves transmitted from the terminal station which has transmitted the code identifying the own station is higher than the threshold value, each of base stations 501 to 503 transmits a control signal for decreasing the power to the terminal station. When the terminal station sends a code for identifying another station or the power of the uplink radio waves received from the terminal station is lower than the threshold value, a control signal for increasing the power is sent to the terminal station. When even one power control signal for giving instruction to decrease the transmission power exists, each terminal station decreases its transmission power. When there is not the power control signal, each terminal station increases its transmission power.

    • 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.

    • A clock signal supply system provides for automatic accurate phase adjustment of clock signals. The system includes an oscillator that produces clock signals and a reference generator that generates a reference signal that has a predetermined relationship with respect to the clock signals produced by the oscillator. At each location where the clock signal is to be received, an adjusting circuit is provided to adjust the phase of the received clock signals. Such an adjusting circuit may include a variable delay circuit which receives the clock signal and produces an output which is constituted by the clock signal having a varied delay, to the remainder of the attached circuits. Further, the output of the variable delay is fed back to a phase difference detection circuit. The reference signal is second input to the phase difference detection circuit. This phase difference detection circuit compares the difference of the reference signal and the output of the variable delay circuit and produces the control signal to the variable delay circuit which will further adjust the phase of the clock signal that is received. This adjustment is carried out at each of the locations where the clock signal is to be received, thereby providing automatic adjustment of the phase of the clock signals.
