  • Patent number: 8127585
    Abstract: First shaped item with shaft part is produced by forward extrusion forming of work, and further, upset forming thereof is carried out to thereby obtain second shaped item with large-diameter part. Subsequently, backward extrusion forming of the second shaped item is carried out to thereby obtain third shaped item having not only cup part provided with ball rolling grooves but also circular diameter expansion portion provided at the mouth area of the inside wall of the cup part along the circumferential direction in such a fashion that the diameter is gradually expanded from the bottom side toward the opening side. Outer ring member for constant-velocity joint is obtained by further subjecting the third shaped item to low-temperature annealing treatment, shot blast treatment and lubricating chemical coating treatment, and thereafter to ironing forming.

  • Patent number: 4787936
    Abstract: The inventive cement-based composition is useful as a coating material for corrosion-resistant protection on steel and iron surfaces. The composition is basically a polymer cement composition prepared by compounding a hydraulic cement with an aqueous emulsion of a polymeric constituent but characteritically the inventive composition is prepared by adding an aqueous emulsion of a hydrocarbon solvent such as kerosene containing a combination of surface active agents, i.e. oil-soluble non-ionic, water-soluble non-ionic and water-soluble cationic ones, and a saccharide compound such as glucose. By virtue of the unique formulation, the composition has a greatly extended pot-life suitable for coating works of, for example, steel rods and pipes by the dip coating method.
