Latest Patents

Fujimura's latest invention revolves around a method for producing a piston ring with a recess. This method involves several critical steps: first, providing a piston ring base material which features an upper surface, a lower surface, and an outer circumferential surface that includes a first recess positioned between the upper and lower surfaces. The process then requires forming a hard film within the first recess and on a cylindrical surface at a specified thickness. Finally, through a polishing procedure on the sliding surface, the hard film and a portion of the piston ring base material adjacent to the hard film are removed, culminating in the formation of a second recess. This innovative process leverages the differing hardness between the hard film and the piston ring base material to achieve its results.
