摘要： A red emission fluorescent display device employing improved SnO.sub.2 :Eu phosphor as a low-energy-electron excitation phosphor. The phosphor is manufactured by the following steps:To a starting material selected from the group consisting of at least one of metallic tin, stannous and stannic halide and stannous sulfate, europium oxide is added in the amount of 5.times.10.sup.-2 to 10 atomic % europium to tin. The mixture is heated and stirred with nitric acid until it becomes dry due to evaporation of the solvent water and unreacted nitric acid, thereby forming a mixed powder of metastannic acid and europium. Then the powder is subjected to heat treatment, causing the metastannic acid to thermally decompose and the europium to diffuse into the stannic oxide matrix.The device exhibts remarkably high luminescence intensity and it is possible to achieve the intensity of 26f.L or more under the E.sub.b of 10 V and the I.sub.b of 1.5 mA/cm.sup.2.

摘要： A red emission fluorescent display device employing improved SnO.sub.2 :Eu phosphor as a low-energy-electron excitation phosphor. The phosphor is manufactured by the following steps:An aqueous solution of a mixture of europium and at least one material selected from stannous halides and stannous sulfate is prepared. The amount of europium ion is adjusted so that the ratio thereof to tin ions ranges between 5.times.10.sup.-2 and 10 atomic %. The solution is poured into and mixed with a hot aqueous solution including oxalic ions, while the mixed solution is being stirred, to form oxalate coprecipitates of tin and europium. After being dryed the coprecipitate is heated so as to be thermally decomposed and then is subjected to heat treatment at the temperature above that for the thermal decomposition, whereby europium ions are diffused into the stannic oxide matrix.The device exhibits remarkably high luminescence intensity which is satisfactory for practical use.

摘要： A humidity sensitive resistor device for sensing the humidity of an ambient atmosphere. The device has a humidity sensitive resistor formed by a metal oxide sintered substrate having electrodes on one surface thereof, the resistivity of the humidity sensitive resistor decreasing as the ambient humidity which can affect the surface of the humidity sensitive resistor increases; and a heater positioned near the humidity sensitive resistor for applying radiant heat to the surface of the humidity sensitive resistor, which heater can be used for improving the sensitivity of the humidity sensitive resistor. By the application of a slight amount of radiant heat, the humidity sensitivity increases, and by the application of a large amount of strong heat, stains which may be on the surface of the humidity sensitive resistor such as oil can be cleaned off so as to recover the sensitivity of the humidity sensitive resistor which might have been deteriorated by the stain.
