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.

摘要： A vehicle running guidance system using magnetic markers for the purpose of reducing the number of magnetic markers to be laid on a road surface. The magnetic nails are laid as magnetic markers on a road. The radio wave generator tags are also laid. The radio wave generator tags transmit road curve data for a distance of about 100 m in the running direction. Power for the radio wave generator tags is supplied from a magnetic generator on a vehicle. On the vehicle, the relative displacement from a magnetic nail is detected by a magnetic sensor, and at the same time the road curve data from radio wave generator tags is received by a radio wave receiving device. The controller determines the amount of steering, based on relative displacement with respect to magnetic nails and road curve data, and supplies it to the actuator. Transmission of road curve data contributes to reducing the number of magnetic nails.

摘要： A prism has at least two optical planes and one of the planes is a boundary plane with mixed fuel. On one of two planes, a light emitting element is mounted and illuminates light to the boundary plane through the prism. A light receiving element receives light reflected from the boundary plane and converts the reflected light into electrical signals. Then a detector modifies the electrical signals from the light emitting element according to the detecting result and outputs them as detecting signals representative of the fuel mixture ratio. The temperature of the mixed fuel may be detected by a temperature sensor in which case the electrical signals are also modified to compensate for temperature changes of the mixed fuel.

摘要： An electronic control fuel supply system for use in an internal combustion engine. The system includes a .lambda. sensor adapted to digitally vary an output signal in response to the air-fuel ratio of an air-fuel mixture being supplied to the engine, and an integrating circuit. The input of the integrating circuit is connected to the output of the .lambda. sensor and has a time constant whereby the open duration of a fuel injection valve provided in the engine intake system is controlled by the output voltage of the integrating circuit. In this fuel supply system, the time constant of the integrating circuit is changed from a first value to a smaller second value after the start of acceleration of the internal combustion engine and during the time that the air-fuel ratio of the mixture is larger than a predetermined value. The integrating circuit is connected to a fuel-amount control circuit which in turn is connected to the fuel injection valve which opens into the intake system of the engine.

摘要： A gas component detection apparatus for detecting gas components contained in an exhaust gas from a combustion device and determining an air-fuel ratio of an air-fuel mixture supplied thereto. A gas component detecting element composed of a semiconductive metal oxide is contacted by the exhaust gas andexhibits variable electric resistances according to the concentrations of the gas components. The electric resistance is taken out as an electric signal through two electrodes disposed either on the surface of the detecting element exposed to the exhaust gas or within the detecting element adjacent that exposed surface. A porous coating layer having an exhaust gas permeability covers the surface of the detecting element exposed to the exhaust gas so as to prevent poisonous substances contained in the exhaust gas from depositing on that exposed surface of the detecting element. The coating layer is formed of a metal oxide having electrically insulating properties and carries therein a catalyst promoting an oxidation reaction of the exhaust gas. The detecting element exhibits an abruptly changed electric resistance when the actual air-fuel ratio of the air-fuel mixture supplied into the combustion device is deviated from a stoichiometrical air-fuel ratio, thereby enabling the control of the air-fuel ratio of the air-fuel mixture.
