摘要： A calculation coefficient used in the arithmetic calculation for controlling the operation of an internal combustion engine is determined by using at least one coefficient stored in a fixed storage, in accordance with a binary number electrical signal. This signal is obtained by converting a variable instruction voltage from a voltage instructing device which can be easily operated. Therefore, by operating the voltage instructing device, the calculation coefficient used in the arithmetic calculation can be very easily changed within a very short period of time, without requiring any additional expense.

The casing includes two axially aligned generally tubular members rigidly secured together at their own ends. The quartz-glass rod has a first portion remote from a sensing end thereof adapted to be exposed to combustion flame in the combustion chamber, and a second portion between the first portion and the sensing end. The first portion is secured to one of the two tubular members of the casing, while the second portion is supported from the casing only by a vibration damping material disposed in engagement with the outer peripheral surface of the quartz-glass rod and the inner peripheral surface of the casing.

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.
