Negatively charged oxygen atoms can be generated by the steps of (A) supplying oxygen to a surface of a solid electrolyte, at which the surface is provided an electrode A', while supplying electric current to the electrode A', to thereby form oxygen ions; (B) causing the oxygen ions formed in step (A) to be transmitted through the solid electrolyte; (C) forming negatively charged oxygen atoms at a surface of the solid electrolyte, an opposite surface on which the electrode A' is provided, by providing electric current to an electrode A on the opposite surface, to thereby produce negatively charged oxygen atoms from the oxygen ions; and (D) applying voltage to an electrode B spaced from the electrode A, in an amount sufficient to generate an electric potential between the electrode A and the electrode B, thereby causing the negatively charged oxygen atoms to move in the direction of the electrode B. The apparatus of the present invention can be used for the above method.

Method for generating negatively charged oxygen atoms and apparatus used

A method of detecting the condition of a liquid layer level in a case where a plurality of liquids are in a layer condition, such method of being capable of knowing each layer level condition even in a case where a system as a whole is high at temperature, pressure or dirt as well as emulsification are large in extent. In order to detect the layer condition, the measurement values of temperatures and so on in a system as a whole or the mathematically processed values of the measurement values are provided as inputs, the layer level condition at this time is outputted, processed by a neurocomputer so as to compose an input-output model. As the layer level condition at this time is adapted to be estimated with the use of the input-output model, the layer level condition may be properly detected even when a system as a whole is high at temperature, pressure or the dirt as well as the emulsification are larger in extent.
