Abstract: A system which accurately detects a position of a vehicle on a road regardless of weather is disclosed. Radio wave reflecting bodies are placed on a road, and transmitter-receiver which can transmit and receive radio waves of wavelength is longer than a millimeter are placed on a vehicle. Based on a ratio of reception strength of the transmitter-receiver in the right and left of the vehicle, a displacement of the vehicle relative to the radio wave reflecting body is detected. The radio wave reflecting bodies have apertures or notches in a predetermined interval so that the radio wave signals reflected thereby has periodicity, and can be distinguished from other objects on the road.

Abstract: A traveling guidance system provides a traveling vehicle with various types of data indicating the flow of traffic to smooth travel. The speed and pass time data of the preceding vehicle is sent to an electronic wave tag laid on a road surface. The electronic wave tag then sends the data to the succeeding vehicle when it passes over the electronic wave tag. Furthermore, the received data is sent to a control center through communication equipment, which predicts the occurrence of traffic congestion based on the speed and pass time data of vehicles at each point and sends the prediction to electronic wave tags at points where the occurrence of traffic congestion is predicted. Traffic data from the control center is sent to passing vehicles through the electronic wave tag and each passing vehicle controls its travel based on the traffic data.

When AFC voltage of a tuner has attained a first predetermined voltage level, frequency sweeping direction for tuning is reversed and stopped thereby to tune the tuner at an optimum tuning frequency. Means are provided to allow the inversion as well as stoppage of the frequency sweeping only when AFC voltage has attained a second predetermined voltage level, thereby to exclude possible erroneous operation due to noise or the like spurious signal components.

Abstract: A bidirectional communication system, including a base station and a plurality of mobile stations, comprises a first unit which alternatively sets a number of transmitting time slots and a number of receiving time slots, each transmitting time slot used by the base station to transmit data to one of the mobile stations on a corresponding one of subchannels assigned for the mobile stations, each receiving time slot used by the base station to receive data from one of the mobile stations on a corresponding one of the subchannels. A second unit changes one of the transmitting time slots and the receiving time slots to a reversed-mode time slot related to a particular one of the mobile stations, whereby the base station uses both the reversed-mode time slot and a corresponding one of the transmitting time slots and the receiving time slots to transmit data to the particular one of the mobile stations or receive data from the particular one of the mobile stations.
