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.

A clocked logic gate circuit is constituted so that a switch unit is constituted by a logic block and a reference MOS transistor, the source of the reference MOS transistor is connected to one output of the logic block, the gate of the reference MOS transistor is connected to the other output of the logic block, and MOS transistors (input transistors) constituting the logic block are connected in parallel. With this arrangement, complementary inputs are not required and a driving MOS transistor and an input transistor (or a driving MOS transistor and a reference MOS transistor) can be connected in series. As a result, a circuit is obtained which is simpler than the double rail logic in constitution is facilitated and can be operated at a higher speed than a CMOS logic circuit and a path transistor logic circuit.

Disclosed herein is a dynamic type circuit which transmits a signal between relatively long-distant circuit blocks lying within a semiconductor integrated circuit chip. A whole signal path thereof comprises a plurality of sections. A section formed by a first type of signal line, which is precharged to a high level and to which a decision as to whether it is driven to a low level according to a signal inputted from a preceding section or it is left in floating state, is made, and a section formed by a second type of signal line, which is precharged to a low level in reverse and to which a decision as to whether it is driven to a high level according to a signal inputted from a preceding section or it is left in a floating state, is made, exist in alternate shifts. The respective sections are respectively connected to preceding-stage sections through MOS transistors for driving signal lines for the sections. MOS transistors for precharge are respectively connected to the signal lines for the respective sections at plural positions where a signal line is partitioned into substantially uniform intervals.

An information processing apparatus is composed of an input layer, a hidden layer and an output layer, and performs a computation in terms of neuron models. In the information processing apparatus, a forward network comprising the input layer, the hidden layer and the output layer executes a computation for externally input data to determine the values of outputs therefrom, and a backward network comprising the output layer and the hidden layer executes computation for output values expected for given inputs to determine learning signal values. The information processing apparatus transfers the output values and learning values between the forward network and the backward network to modify the synapse weights of the neuron models.
