摘要： A synchronizing signal discrimination circuit for use in a channel selection apparatus having a preset function of a television receiver is disclosed. The circuit has a function to discriminate a periodic and continuous signal and a non-periodic and one-shot signal to distinguish a synchronizing signal from a noise. The present synchronizing signal discrimination circuit determines a time period from the application of a first input signal to the input terminal to the application of a second input signal to the input terminal by the first time interval signal and the second time interval signal to detect only the periodic and continuous signal as the synchronizing signal.

摘要： A search tuning type channel detector system for television receivers. 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.

摘要： A digital-to-analog converter of a pulse width modulation type in which a single counting cycle of a clock pulse counter is divided into 2.sup.m elementary periods where m represents a selected number of less significant bits of a digital input data to be converted into analog quantity and elementary pulses in number determined in dependence on the logic values of the more significant bits are distributed among the elementary periods, while supplementary elementary pulses are produced in the elementary periods selected in dependence on the logic values of the less significant bits of the digital input data. These elementary pulses are integrated for every elementary period and the integrated output value is converted into a corresponding DC analog output signal.

摘要： 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.

摘要： 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.
