Filed: 2002-06-12
Abstract: <P>PROBLEM TO BE SOLVED: To improve the production efficiency in the carbonization process of a chamber inside wall-protecting member comprised of glassy carbon for a plasma treatment device, and to easily achieve high dimensional accuracy or roundness.  <P>SOLUTION: The chamber inside wall-protecting member comprised of a glassy carbon cylindrical body for a plasma treatment device is formed into a truncated cone shape by deforming a thermosetting resin sheet along a conical mold and joining the both ends thereof. Thus, the carbonization can be performed by inserting one of the cylindrical body with a truncated cone shape such that the outer peripheral surface thereof is brought into contact with the inner peripheral surface of the other cylindrical body and stacking the tubes in multiple layers to charge into a furnace, thereby remarkably increasing the loading density and the production efficiency of the carbonization requiring a long time. In addition, as the inner peripheral surfaces and outer peripheral surfaces of the stacked cylindrical bodies are held by respective adjacent cylindrical bodies, the dimensional variations of the inner and outer diameters can be prevented and good roundness can be achieved.  <P>COPYRIGHT: (C)2004,JPO
