    Abstract: PURPOSE:To attain high quality while achieving measurement in a short time with high precision, by reducing the capacity of a generation space for reference gas by stacking diaphragms of plane electrolyte and by interposing a prescribed conductive substance between the stacked surfaces. CONSTITUTION:A diaphragm 1 which has electrodes 5 and 6 on both plate surfaces of a plane solid electrolyte and a diaphragm 2 which has electrodes 7 and 8 on both plate surfaces of a plane solid electrolyte having a fine through hole 3 in the thickness direction are so stacked that the plate surfaces face mutually; and annular conductive foil 4 is interposed between their stacked surfaces to joint both the diaphragms 1 and 2 in one body with the conductive foil 4. Then, a DC current with a prescribed value is flowed between the electrodes 7 and 8 to substitute a small-capacity space 9 with reference gas. In this state, gas to be measured is brought into contact with the electrode 5 to generate electromotive force between the electrodes 5 and 6. This electromotive force is measured to obtained the oxygen concentration of the measured gas.

    Abstract: PURPOSE:To enable to increase a current made to flow between electrodes by a method wherein one of the electrodes provided on both surfaces of a partition wall of a solid electrolyte is formed into two independent electrodes and the electrode on the reference side is covered with an enclosing body allowing a minute quantity of gas to permeate. CONSTITUTION:Two independent, reference electrodes 2 and 2' are provided on one surface of the partition wall 3 of the solid electrolyte having oxigen ion conductivity, while measuring electrodes 1 and 1' are provided on the other wall surface. In addition, the side of the reference electrodes 2 and 2' has an extremely small opening area at the top thereof and this is covered with the enclosing body 12 which is formed of material not allowing permeation of the gas and has a gas conductive port 8 allowing a minute quantity of the gas to be passed. When a prescribed DC current is made to flow between the opposed electrodes 2' and 1' in one couple by a DC power source 6, the inside of the space of the enclosing body 12 is replaced by a reference gas having a prescribed partial pressure of oxygen. Then, the gas to be measured is made to contact with the electrode 1 and an electromotive force generated between the electrodes 2 and 1 is measured by a measuring device 7.

    Abstract: PURPOSE:To make it possible to detect incomplete combustion at combustion apparatus precisely and with high accuracy by forming a diaphragm of a solid electrolyte having an oxygen ion conductivity in a bent plate shape and providing porous electrodes on both surfaces. CONSTITUTION:A diaphragm 1 of a solid electrolyte made of a sintered body of a solid solution consisting of zirconia or the like and magnesia or the like having oxygen ion conductivity is formed into a bent plate shape. Porous electrode plates (platinum, gold, nickel plates or plates of alloys thereof) 2 and 3 are provided on both surfaces of the diaphragm 1, and lead wires 4 and 5 are connected thereto to manufacture a senser 6. The senser 6 is provided so that the bent recessed surface is in opposite to the combustion flame. Thus, incomplete combustion is detected from the potential difference based on the difference between the O2 partial pressure in the exhaust gas on the recessed surface and that in the atmosphere, and an alarm is issued. Since the senser 6 is bent, even when the lift-up of the flame occurs, variation in the temperature distribution in the thickness direction of the diaphragm 1 is slight, and therefore the accuracy of the detection is not lowered.

    Abstract: PURPOSE:To efficiently produce the title powder of high purity by suspending metal oxide fine powder in a carbohydrate soln.; heating the suspension to carbonize the carbohydrate; and heating the resulting carbonaceous residue under an atmosphere contg. vapor of a N-contg. cpd. CONSTITUTION:Metal oxide fine powder is suspended in a carbohydrate soln. When a solid carbohydrate such as paper, pulp or rayon is used, it is finely pulverized to below 1 mu and suspended in water or other suitable liquid medium. It may be dissolved in an org. or inorg. solvent and used. an aq. soln. of starch, glucose or sucrose, or a soln. of a hydrolyzate thereof may be used. The suspension is then heated to above 250 deg.C to carbonize the carbohydrate as well as to remove volatile components. The resulting carbonaceous residue is heated to 700-2000 deg.C under an atmosphere contg. vapor of a N-contg. cpd. such as NH3 or CH3NH2 to convert the metal oxide in the residue into metal nitride.

    Abstract: PROBLEM TO BE SOLVED: To improve luminance and color purity of display by applying a photolithography method which allows excellent patterning and is advantageous to cost by using photosensitive paste which contains low melting point glass and changes to white after calcination. SOLUTION: The photosensitive paste contains the low melting point glass as an indispensable constituent. By using the low melting point glass, patterning property at the time of exposure is not hindered and a partition wall can be formed by calcination. Further it is important for the photosensitive paste to change to white after calcination. When the photosensitive paste does not change to white after calcination, display characteristic of high luminance cannot be attained after calcination even if the transparent photosensitive paste, for example, is used by expecting high transmissivity at the time of exposure. Meanwhile when the photosensitive paste displaying white before calcination is used, even exposure light is reflected and excellent patterning cannot be obtained. One kind selected from a group composed of compounds of Al, Zr, Ti, Ce or the like is preferably contained in such a paste.
