摘要： A method of producing fine particles with a particle size of submicron or finer which comprises the steps of:forming closely fine projections on a substrate surface, preferably by sputter-etching using an ionized gas; and thensputtering metallic or non-metallic materials onto the thus treated substrate in an inert gas or a mixed gas of an inert gas and a reactive gas, such as oxygen, the gas pressure of the inert gas or the mixed gas being in the range of from 1.times.10.sup.-4 torr to 1.times.10.sup.-1 torr, and thereby depositing the purposed fine particles in crystalline or amorphous form. The invention method can successfully provide fine particles with desired properties, for example, in size, shape and structure, by adjusting producing conditions or selection of substrate materials and the thus obtained fine particles are very useful in various applications with or without the substrate.

摘要： A nitrogen oxide sensor includes a solid electrolytic substrate exhibiting oxygen ion conductivity, a noble-metal reference electrode, which is active only to oxygen, formed on one side of the solid electrolytic substrate, and a sensing electrode, which is active to NOx and oxygen, formed on the opposite side of the solid electrolytic substrate. A potential difference across the sensing electrode and the reference electrode is output as a signal indicative of NOx concentration. Nitrogen oxides in a gas to be examined or measured gas are converted to NO2 and to peroxides of nitrogen such as N2O5 and NO3, after which the nitrogen oxides in the gas to be examined or measured gas are sensed by the sensing electrode as the peroxides of nitrogen such as N2O5 and NO3 or as a mixed gas of NO2 and the peroxides of nitrogen.

摘要： A stable sensor designed to detect accurately the total NOx concentration under 100 ppm in terms of the NO gas concentration is made up of a first cell and a second cell with a gas diffusion aperture provided between the two cells. The first cell has a partition wall of a substrate of oxygen ion conductor containing zirconia as the main component and permitting a gas to be detected to enter the zirconia substrate; oxygen pumping electrodes are also formed on the first cell substrate which functions to expel oxygen in an atmosphere of the first cell to the outside and to reduce NO.sub.2 of the NOx gas to be detected to NO gas. While NO gas entering through a gas diffusion aperture between the two cells flows into the second cell, a measurement is made of an electromotive force between a NO detection electrode formed in the second cell and a counter electrode also formed therein or a counter electrode formed on the reverse side of the zirconia substrate, since such electromotive force corresponds to the level of the NO gas concentration and thus provides the total NOx concentration.
