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.

摘要： A gas component detection apparatus comprises a first and a second gas sensing elements each composed of a metal oxide which exhibits variable electric resistances according to gaseous components and temperatures of gases to be detected. A catalyst is carried at least by the first sensing element for promoting oxidation reactions of the gaseous components of the gases. A first pair of electrodes are inserted into those portions of the first sensing element which are subjected to catalytic action of the catalyst. Into the portions of the second sensing element which are not subjected to catalytic action are inserted a second pair of electrodes. The first pair of electrodes sense a variation in electric resistances resulting from the gaseous components and temperatures of the gases, while the second pair of electrodes detect an electric resistance variation related mainly upon the gas temperatures. Consequently, an output signal reflecting substantially only the gaseous components of the gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.

摘要： A gas component detection apparatus for detecting gaseous components of exhaust gases from a combustion device. There is provided a gas component detecting element composed of semiconductive metal oxides and having its outer surface partly exposed to the exhaust gases. A catalyst layer is carried on the larger part of the latter outer surface of the detecting element. A pair of electrodes are provided for sensing the electric resistance exhibited at the portion of the detecting element which carries the catalyst layer. Also another electrode is provided for cooperating with one of the above pair of electrodes to detect the electric resistance exhibited at the portion of the detecting element which does not carry the catalyst layer. The former portion of the detecting element exhibits variable electric resistances resulting from concentrations of the gaseous components and the temperatures of the exhaust gases, while the latter portion thereof exhibits variable electric resistances related mainly upon the temperatures of the exhaust gases. Consequently, an output signal reflecting substantially only the gaseous components of the exhaust gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.

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： A combustion process sensor for detecting combustion processes occurring in a combustion chamber of an engine has a generally tubular mounting casing to be screwed into a threaded hole in the combustion chamber wall and a quartz-glass rod axially extending in the mounting casing and held in position therein. 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.
