    摘要： In a gas sensor which uses CuO as a p-type semiconductor, by adding Na.sub.2 CO.sub.3 in excess of 1 wt % relative to CuO, sensitivity to gases such as H.sub.2, NO, NO.sub.2 and SO.sub.2 is suppressed, whereby selectivity for CO is increased. Sensitivity to CO.sub.2 can also be obtained. In addition, by adding a sodium salt of tungstic acid or molybdic acid, CO.sub.2 sensitivity can be made lower than the CO sensitivity, and CO gas in the exhaust gases discharged from gas-fired water heaters or other combustion equipment can be selectively detected. It is therefore possible to detect incomplete combustion.

    摘要翻译： 在使用CuO作为p型半导体的气体传感器中，通过相对于CuO添加超过1重量％的Na 2 CO 3，抑制了对气体如H 2，NO，NO 2和SO 2的敏感性，从而提高了对CO的选择性。 也可以获得对二氧化碳的敏感性。 此外，通过添加钨酸或钼酸钠盐，可以使CO敏感性低于CO敏感度，并且可以选择性地检测从燃气热水器或其他燃烧设备排出的废气中的CO气体。 因此可以检测不完全燃烧。

    摘要： A metallic coating method is carried out by contacting a surface of a substrate with a molten metal which is locally raised under ultrasonic vibration. A metallic coating can be continuously attained on one side only of ribbon type substrate in a form of plate, sheet or strip or only the outer surface of a pipe.

    摘要： This invention concerns a humidity sensor wherein a chemical conversion coating, giving attention to the property that it undergoes an impedance decrease with adsorption of moisture, is used as humidity sensing element which is characterizied by an extremely short electrode distance, greatly improved sensitivity, high speed response, stable performance over a long period of time, high reliability and cheaper production cost.The principal point that characterizes the humidity sensor in this invention is that the chemical conversion coating deposited on the metal surface with or without an electrolysis application, is made usable as a humidity sensing element. For the chemical conversion coating, such coatings as phosphate, oxalate, titanium fluoro-complex, chromium phosphate and non-chromium types are used.On top of this chemical conversion coating, application of a humidity sensing film is effected to further improve humidity sensing performance.

    摘要： P-type semiconductor 15 and n-type semiconductor 16 are formed as thick films or spray-coated onto electrodes 13 and 14 on top of substrates 11 and 12, with films of p-type semiconductor 15 and n-type semiconductor 16 being formed in such manner that they are in mutual contact. If a gas to be detected is introduced to the contact region while a bias voltage is being applied between the two electrodes, an output will be obtained in accordance with the concentration of flammable gas components in the gas being detected. In addition, if a film is formed from a material comprising a mixture of particles of p-type semiconductor and particles of n-type semiconductor, the bias voltage can be an AC voltage.

    摘要： A resistance element causing less sliding noise for use in wound-type variable resistors and a method of making the same are disclosed. A resistance element obtained by winding a metallic resistance wire on a core is subjected to etching treatment. With this etching treatment, the metallic oxides, chlorides and sulfides considered acting as insulators, and organic molecules, adsorbed gases and other contamination forming the surface layer of the resistance wire are dissolved and removed. Furthermore, by immersing the etched resistance element in an ammonia solution, etc., the copper precipitated on the surface of the resistance wire is dissolved.
