摘要： A motor component covered with a novel electrocoating that fails to detrimentally affects magnetic memory medium provided in a hard disc or other is provided. With enhanced edge covering ratio, an improved insulation coating is easily formed on the motor component. An insulation coating is electrodeposited on an Nd--Fe--B system plastic magnet, a stacked core of silicon steel, a die-cast motor base of aluminum or other motor component through cationic electrodeposition. The electrodeposition paint for use includes 12 ppm or less of tin content in the aqueous solution, 0.5% or less by weight of carbon black content in the aqueous solution, and, instead, has titanium dioxide and/or silicon dioxide added to pigment. The electrodeposited insulation coating, which has a specified thickness, is heated to temperatures ranging between 40.degree. C. and 90.degree. C. After such preliminary curing, temperatures are again heated to between 150.degree. C. and 190.degree. C. In the hard disc drive unit assembled of such electrodeposited components, no tin is scattered therefrom, thereby protecting memory content from collapsing, and providing enhanced anticorrosion and insulation.

摘要： An oxygen gas concentration-detecting apparatus for use in an internal combustion engine comprising a plate-shaped substrate, a plate-shaped oxygen ion-conducting solid electrode for generating an electromotive force between a first surface contacted with air and a second surface contacted with an exhaust gas of the engine according to the difference between the concentrations of oxygen gases of the air and the exhaust gas, the solid electrode being laminated on the substrate, a pair of electrode members for taking out the electromotive force as a detection signal and a nitrogen oxide-reducing catalyst layer for promoting the reduction of nitrogen oxide arranged to cover the second surface of the oxygen ion-conducting solid electrode. By this apparatus, the concentration of oxygen gas inclusive of oxygen gas generated by reduction of nitrogen oxides can be precisely detected. The plate-shaped oxygen gas concentration-detecting apparatus enables to easily form a uniform catalyst reaction surface and to easily be heated so as to promote the stable reduction reaction of the nitrogen oxide-reducing catalyst layer.

摘要： Disclosed is an oxygen gas concentration-detecting apparatus comprising a ceramic substrate for generating an electromotive force according to oxygen gas concentration of gases contacted with both the surfaces of the ceramic substrate, a pair of electrode members arranged on the ceramic substrate to take out the electromotive force, an oxidation catalyst layer formed on the outer surface of the ceramic substrate to promote oxidation reaction of unburnt components and a reduction catalyst layer arranged on the outer surface of the ceramic substrate to promote reduction reaction of nitrogen oxides. By this apparatus, the concentration of oxygen gas inclusive of oxygen gas generated by reduction of nitrogen oxides can be precisely detected, and discharge of nitrogen dioxides is controlled and a so-called EGR control device can be omitted. When this oxygen gas concentration-detecting apparatus is applied to an air-fuel ratio feedback control apparatus in an internal combustion engine, the above-mentioned effects are enhanced.
