摘要： A method of coating an object by shifting from a first coating solution to a second coating solution. After a coating of the object with the first coating solution is finished, a washing solution is used to clean a coating pipe-line and a coater. Deaerated water is supplied to fill up the pipe-line and the coater by control of a multi-way valve which is located at an end of the coating pipe-line which is connected to one of a coater or an outlet for drainage. The multi-way valve is capable of shifting a fluid flow therethrough to one of the coater and to the outlet. With the multi-way valve in the outlet position the deaerated water is replaced in the pipe-line and the coater with the second coating solution. A slit inside the coater is dried, and the second coating solution is then conducted to the coater by shifting the multi-way valve to a coater position therefor.

摘要： An inexpensive rolling bearing is proposed which can be used stably for a long time where the lubricating conditions are severe or bending stresses act. Inner and outer rings of rolling bearings mounted in a rocker arm of an automobile are made of high-carbon chrome bearing steel. They are subjected to heat treatment in which after carbonitriding, high-temperature tempering is carried out. Then they are induction hardened to impart resistance to material quality change and a compressive stress of not less than 200 MPa to the surface layer, thereby markedly improving the rolling contact fatigue life and the tension-compression fatigue strength while keeping the material cost as before. Thus, this bearing can be used stably for a long time even though it is a full complement type bearing, lubricating conditions tend to worsen and the outer ring is repeatedly subjected to bending stress from the cam.
