161	Components for substrate processing apparatus and manufacturing method thereof	US11270671	2005-11-10	US08058186B2	2011-11-15	Tsuyoshi Moriya; Kouji Mitsuhashi; Akira Uedono
A focus ring is shaped by cutting off a silicon carbide body formed by a sintering method or a CVD method. The shaped focus ring is exposed to a plasma generated from at least one of a carbon tetra fluoride gas and an oxygen gas for producing impurities, and the impurities are introduced to void-like defects existing in the vicinity of a surface of the focus ring. Subsequently, positrons are injected in the vicinity of the surface of the focus ring into which the impurities are introduced, and the defect density in the vicinity of the surface of the focus ring is detected by the positron annihilation method.

The restoration of monuments and other objects made of stone is described. The process is carried out by immersing the stone object in deionized water in order to dissolve the calcium sulfate contamination present on the deteriorated stone which is caused by the pollutants present in air, then circulating the water containing the dissolved calcium sulfate through an ion exchange resin which can selectively trap the sulfate and release calcium hydroxide into the solution, followed by exposure to carbon dioxide under controlled conditions in order to thereby reprecipitate the calcium ions on the stone object as the carbonate in the calcite crystalline form.

Absorptive substrates, such as asbestos cement, concrete plaster work, can be impregnated to lock the pores and to consolidate the substrate, especially old and weathered plaster work, with aqueous plastics dispersions, if dispersions are used which have an average particle size of about 0.02 to at most 0.1.mu.m, and preferably from 0.036 to 0.080.mu.m. As opposed to conventional dispersions with larger particle sizes, the penetration of dispersions according to the invention reaches the same values as that of the solvent-based impregnating and priming compositions hitherto used. Aqueous dispersions are easier to handle and permit relatively high solids contents at a moderate viscosity.
