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 method of producing a laminated dielectric element of high quality, free of delamination. A method of producing a laminated dielectric element 1 by alternately laminating dielectric ceramic layers 12 and base metal electrode layers 13, comprising the steps of printing electrodes by applying a paste material for the base metal electrodes onto the surfaces of at least one side of the ceramic green sheets, laminating and press-adhering the ceramic green sheets to fabricate a laminate thereof, dewaxing the laminate, reducing the electrodes to form base metal electrode layers by heating the laminate while flowing an atmospheric gas and by reducing the paste material for the base metal electrodes, and sintering the laminate. In the step of reducing the electrodes, the paste material for the base metal electrodes is so reduced that the amount of the base metal oxide remaining in the base metal electrode layers is not larger than 20% by weight and that the amount of lead liberated from the ceramic material is not larger than 30 atomic % within 5000 Å from the surfaces of the base metal electrode layers.

摘要： A method of manufacturing large-sized laminated dielectrics of high quality which permit adjustment of the atmosphere during sintering process to be accomplished easily, and which can eliminate the problems such as expansion due to reaction with the atmosphere gas. When a laminated body 1, consisting of oxide dielectric layers 2 and inner electrode layers 3 having a base metal such as Cu as a main component, is sintered in a reducing atmosphere, a mixed gas having CO2 gas as a main component and containing optional amount of CO gas and O2 gas is used. By using the equilibrium system of CO2⇄2CO+(1/2)O2 and adjusting the amounts of CO gas and O2 gas, oxygen partial pressure in the atmosphere gas can be easily and stably adjusted and fluctuation and variation in the atmosphere can be suppressed.

摘要： A ceramic piezoelectric transformer is provided which includes a compression mechanism. The compression mechanism is made up of, for example, a bolt and a nut which add a given compressive stress to a transformer body in a lengthwise direction thereof for absorbing a tensile stress arising from oscillations of the transformer body during operation, thereby allowing output energy from the transformer to be increased. In a modified form, a weight block is mounted on an end of the transformer body to increase the range of the output energy.
