Abstract: There is provided a method for producing a metal/ceramic bonding article wherein a metal member 12 is formed so as to have a predetermined shape by printing a resist 14 in a predetermined region on the metal member 12 to etch the metal member 12 after bonding the metal member 12 to a ceramic member 10. In this method, at least one strip-like non-printed portion 16 having a width of, e.g. 0.01 to 0.5 mm, in which the resist is not printed, is provided in a region inwardly spaced from the outer periphery of the resist 14 by a predetermined distance, e.g. 0.01 to 0.5 mm, to control the etch rate in the outer peripheral portion of the metal member 12. Thus, the width and thickness of a fillet is freely changed. For example, a stepped portion (or a stepped portion and fillet) having a width of 0.05 to 0.5 mm and a thickness of 0.005 to 0.25 mm is formed in the outer peripheral portion of the metal member 12.

Abstract: A side rail is formed into a ring shape having its generally rectangular section that has an outer surface 3 formed with a pair of edge surfaces 5 of small radius, and an intermediate surface 6 of large radius of curvature formed between the edge surfaces 5. When the side rail is in the inclined condition in operation, each edge surface 5 can easily ride on oil film on cylinder 16 and allow the side rail 1 to perform smooth sliding movement on the inner surface of cylinder. The intermediate surface 6 efficiently scrapes lubricating oil on cylinder to form lubricating oil film of necessary and minimum thickness between an inner surface 17 of cylinder 16 and side rail 1. Also, the larger radius of curvature for forming the intermediate surface 6 provides a larger contact area to the inner surface 17 of cylinder 16 to improve wear resistance.
