6592798 Method for preparing eutectic ceramics July 15, 2003
A method for advantageously producing sintered eutectic ceramics having a homogenous and dense structure, in particular, a eutectic containing a rare earth aluminate compound. The method allows eutectic powder of alumina and a rare earth aluminate compound to stand at a temperature of
5164221 Forming die manufacturing method November 17, 1992
A manufacturing method of a forming die includes the steps of depositing a film of aluminum nitride or aluminum oxynitride on the forming surface of a forming member by passing an electric discharge through a mixture gas of halide of aluminum and a gas containing nitrogen atoms and hydro
5093156 Process for preparing carbon material March 3, 1992
A carbon material having oxidation resistance is prepared by forming a fi coating constituted mainly by carbon on the surface of a carbon/carbon composite by chemical vapor deposition, then forming on said first coating a second coating of a ceramic or both a ceramic and carbon by chemi
5093150 Synthesis method by plasma chemical vapor deposition March 3, 1992
A method of synthesizing metal-containing material by a plasma chemical vapor deposition comprises converting a reactive gas containing metal atoms into plasmas in a reaction chamber and supplying an inert gas from outside the plasma region in the reaction chamber. Ceramic films of e
4985117 Method of manufacturing josephson junctions January 15, 1991
A method of manufacturing Josephson junctions includes steps of high Tc superconductor thin films on a substrates by chemical vapor deposition using raw materials, which includes at least yttrium, barium and copper, serving as vapor generating sources, and fabricating the high Tc sup
