Abstract: PURPOSE:To surely form an Fe-P plating film free from cracks by adding an Al compd. to an Fe-P electroplating bath contg. divalent Fe ions and phosphorous acid or phosphite as essential components. CONSTITUTION:An Al compd. is added to an Fe-P electroplating bath contg. divalent Fe ions and phosphorous acid and/or phosphite as essential components. By using the resulting plating bath, a plating film free from cracks is surely formed and a sliding member having superior wear and seizing resistances can be obtd. The pref. content of the phosphorous acid and/or phosphite in the plating bath is 0.01-20g (expressed in terms of NaH2PO3.2H2O) per 1l plating bath, that of the Al compd. is 0.05-5g/l (expressed in terms of Al ions) and that of the divalent Fe ions is about 20-80g/l. The proper pH of the plating bath is about 0.5-3.5, the proper temp. of the bath is room temp. to about 80 deg.C and the proper cathode current density is about 0.5-30A/dm .

Abstract: PROBLEM TO BE SOLVED: To provide a wet type multiple disk clutch of high operating precision by reducing the generation of drag resistance at the time of lifting a clutch engagement. SOLUTION: A plurality of concave portions 18a are formed in a circular ring plate 18. The concave portions 18a is provided with a pitch which is different from a circular arc disk frictional radial oil groove which is composed of multiple disk clutch together with the circular ring plate 18. Accordingly, it is not necessary that an assembling phase of the circular arc disk and the circular ring plate 18 is severely controlled and some of the plurality of concave portions 18a are positioned out of the radial oil groove of the frictional material. In the concave portions 18a inside out of the radial oil groove of the frictional material, the lubricating oil is sealed when the circular arc disk and the circular ring plate 18 stick each other. Then, upon releasing of the clutch engagement, the lubricating oil sealed in the concave portions 18a stimulates to estrange the circular arc disk and the circular ring plate 18.

Abstract: PURPOSE: To provide a check valve without the deformation of a seal surface by the load at the time of the caulking or press fit of a housing member. CONSTITUTION: When a caulking part 11C is caulked, since a small diameter part 11B has a larger diameter and higher rigidity than those of the part 11c, the part 11c has bearing force to a diameter direction load, and the caulking can not affect a seat surface 15 to prevent the deformation of the surface 15. When a housing member 11 is pressed in the pipe line 51 of a fluid apparatus 50, since a large diameter part 11A has a diameter larger than that of the part 11b to cause a step part 12 between both sides to generate the bearing force to diameter direction load input at the time of press fit, the deformation of the surface 15 can be prevented.

Abstract: PURPOSE:To provide the sliding member capable of shortening the time required for mirror finishing of a contact surface. CONSTITUTION:After the surface of a base material 50 of a shim is finished to about 0.3mumRz, a coating layer 51 consisting of titanium nitride is formed by an arc type ion plating method. The current density at the time of the treatment is regulated to 60 to 90MA/cm , by which droplets having 0.7 to 5.2% ratio of the total area of the section when base material is cut at 0.5mum height to the area of the base material are formed on the surface. The cam contact surface is mirror finished to roughness of
