Abstract: A crimping tool according to the invention includes a cylindrical C-5 carbide rod having a plurality of laser cut pyramid points on one end. An adapter sleeve is also provided for attaching the tool to an existing pneumatic press. The pyramid pattern on the end of the tool provides several unexpected benefits. First, the points engage the eyelet and prevent the tool from slipping off the eyelet during the crimping operation. Second, the crimps produced by the tool have a greater surface area than the conventional crimps, exerting more pressure on the wick core without shearing fibers. The pressure exerted on the wick is 25-35% greater than a conventional crimp. Further, the carbide material wears much slower than the conventional crimping tools. This assures a consistency in crimping over a long period of time. An exemplary embodiment of the crimping tool according to the invention is approximately 1.625 inches long and approximately 0.090 inches in diameter.

Abstract: A method of manufacturing a hollow piston for variable displacement swash plate compressors of air conditioning systems is disclosed. This method produces a desired hollow piston by separately forming a body and a cap and by simply machining the body and the cap prior to simply welding the body and the cap together into a single structure through a frictional welding process. This method thus remarkably simplifies the pre-welding machining process. In the frictional welding process, the body and the cap are welded together into a single structure by simply and relatively rotating the body and the cap while forcing them toward each other under atmospheric air at room temperature. The frictional welding process is thus accomplished using a simple welding machine, thereby reducing the equipment cost while producing the hollow pistons. The frictional welding process is also free from oxidizing the welded portions of a resulting hollow piston, and so the resulting piston does not have micro pores in its structure.

Blade material along only radially outermost portions of the leading and trailing edges extending from the tip towards a base of the airfoil is machined away. A rounded corner is formed between the leading edge and trailing edge cut-backs and unmachined portions of the airfoil between the outermost portions of the leading and trailing edges and the base of the airfoil.

Abstract: According to this dynamic pressure groove processing method, dynamic pressure grooves are formed in specified regions by electrochemical machining with the electrode of an electrode tool put close to a workpiece in the initial stage. Through this electrochemical machining, corners of land portions adjacent to the dynamic pressure grooves can be curved and smoothed. Next, by subjecting the workpiece to electrochemical machining with the electrode of the electrode tool put away from the workpiece, the land portions are to undergo weak electrochemical machining. Surface roughness of surfaces of the land portions can be reduced, and the curved corners of the land portions can be made smoother at the same time. Therefore, the abrasion resistance characteristic of the dynamic pressure grooves can be improved further than that achieved by the conventional electrochemical machining, allowing the abrasion resistance characteristic and reliability to be sufficiently improved.
