  • Patent number: 6440590
    Abstract: A structure comprising silicon-containing ceramic body and an active metal-containing metal layer as a brazing layer or a metallization layer bonded to and disposed on the surface of the ceramic body. A reaction layer of a compound containing constituent elements of the ceramic body and the active metal is formed in the interface between the ceramic body and the metal layer. The reaction layer is present ahead the outer circular edge of the metal layer. In particular, when the ceramic body is silicon nitride with the active metal being titanium, the reaction layer comprises a first reaction layer composed mainly of titanium nitride and a second reaction layer composed mainly of titanium silicide. The first reaction layer is present ahead the outer circular edge of the second reaction layer. According to the brazed structure and the metallized structure, the characteristics of the metal layer containing the active metal, such as bonding strength, can be improved with good reproducibility.

  • Patent number: 6431490
    Abstract: A process and apparatus for depositing simultaneously by winding on a support, several rovings of pre-impregnated fibers. The rovings are deposited simultaneously by winding on a rotating support. At least two rovings are brought into superposition near where they will be applied to the support, and the various rovings are subjected to different tensions depending on their position relative to the support. Specifically, the roving nearest the support is subjected to a greater tension than a roving farther from the support. Composite structures are thus produced.

  • Patent number: 6410173
    Abstract: The invention includes a bilayer antireflection coating, multilayer antireflection coatings, and a method for making a multilayer antireflective coated substrate. The bilayer and multilayer coatings include layers having metallic oxides, at least one layer in each of such coatings having as a material with an index of refraction at least about 1.90, a layer comprising oxides of zirconium such that when subjected to heat treatments, such as tempering, the coatings substantially retain their optical properties. The coatings further include layers having materials of low index of refraction which include oxides of aluminum which provide coating stability and increased coating solution storage life. In the method, the layers are applied by successive dip coating techniques using solvent-based solutions and the resulting coatings can be used to coat large sized substrates which can be later cut, trimmed and/or otherwise shaped and later heat treated with substantial retention of optical properties.

  • Patent number: 6399203
    Abstract: Since the dense and high purity pyrolytic-carbon-coated layer is formed with a thickness of 10-100 &mgr;m on the surface of the C/C composite, even when metallic impurities of the inside C/C composite are 5-100 ppm in ash content, similar effects to those of a known crucible made of the C/C composite whose inside was subjected to high purification can be produced to achieve full applicability to the structural elements of the CZ apparatus. Also, since the process time required or the C/C composite itself to be subjected to the high purification can be shortened, the effect of reducing the manufacturing costs considerably can be obtained.

  • Patent number: 6395220
    Abstract: Carbon fiber bundles may be dispersed into substantially single mono-filaments in pitch by stirring a mixture of fibers and pitch at a temperature at which the pitch has a viscosity of about 0.1 to about 5 poise. The resulting fiber pitch binder contains about 0.5 to about 10.0 wt. % carbon fibers substantially dispersed as substantially single mono-filaments which are randomly oriented which may then be used directly as a binder for producing carbon bodies, for example, graphite electrodes, pinstock or specialty graphite articles. This unique binder using an economical amount of carbon fibers has the capacity to increase the strength and reduce the coefficients of thermal expansion of the resulting carbon products in more than one direction due to the random orientation of the carbon fibers.
