摘要： An exhaust gas purifying catalyst for purifying exhaust gas discharged from an internal combustion engine of an automotive vehicle. The exhaust gas purifying catalyst comprises a substrate on which a catalytic coat layer containing a catalyst component is formed. The catalytic coat layer is formed by coating a slurry containing the catalyst component on a surface of the substrate. A crack-preventing coat layer is formed on an upper-most surface of the catalytic coat layer. The crack-preventing coat layer has a thickness of not larger than 50 nullm.

摘要： During the deposition of a catalytic component on a carrier, the position of the liquid level of a slurry containing the catalytic component is controlled with high accuracy and the adhesion of the slurry to the lateral face of the carrier is prevented. In the deposition of the liquid substance on the carrier by the introduction of the liquid substance into the carrier from the bottom face thereof, the liquid level near the top face of the carrier is detected by an image-processing sensor.
