Abstract: PURPOSE: A method is provided to maintain the sealed state though a piston reciprocation over 100000m is performed by having the high surface solidity and the low roughness with an ionitriding process and a finishing process. CONSTITUTION: A material of a piston rod is cut and lathe-processed. The piston rod is refined. A surface of the piston rod is ion-nitrified. The surface of the piston rod is finished with an IDLF(Imperial Diamond Lapping Film). The finishing process is performed by an automatic super-finisher. The finishing is performed by vibrating leftward and rightward at 1.8-2.0Hz frequencies while the IDLF around a roll of the automatic super-finisher presses the surface of the piston rod(16). The piston rod(16) is rotated by a lathe center. The transfer speed of the IDLF is 15-30mm/min and the RPM of the lathe center is about 1800. A surface roughness is under RA 0.03 by the IDLF of a 1-3 μm mesh grade. Processing time is reduced by using the IDLF having the large mesh grade when the low surface roughness is unnecessary.

Abstract: PURPOSE: A traverser with tow-stage level roller is provided to transfer by alternatingly loading cargoes having corresponding size over a first-stage roller or second-stage roller during transfer of cargoes of different sizes with one traverser. CONSTITUTION: In a state that a traverser(100) fixed with two-stage level rollers(113) is installed in a storage room, a worker loads and transfers a cargo on the two level rollers of a traverser. Roller shafts(130a,130b) connected to the inner face of traverser frames(120a,120b) depending on the on-action of the traverser conduct a roller drive action aligned horizontally. Correspondingly, the two-stage level rollers linked rotatably to the roller shafts perform rotational motion in the same direction of the rotation of the roller shafts. Thus, the cargo positioned over the two-stage level rollers are transferred along the rotational direction. Herein, the transferred cargo is differently loaded on the two level rollers according to size and, in case of a large cargo, the cargo is loaded on the entire area of the second stage rollers or two level rollers.
