Abstract: When a mixture of gases containing carbon is burned to form a film of diamond on a surface of a substrate held at an appropriate temperature, it is so burned as to form a substantially flat region of incomplete combustion lying in parallel to the substrate surface and contacting it, while the region is surrounded by an air-shielding gas stream or formed under a reduced pressure.

Abstract: It is an object of the present invention to provide an excellent silicon oxide film formed at a temperature of 200.degree. C. or less, a method of forming the silicon oxide film, and a selective growing method. According to the present invention, by using a vapor containing alkoxyfluorosilane as a main component, a silicon oxide film containing fluorine is formed at a temperature of 200.degree. C. or less in a reaction chamber having a predetermined temperature and a predetermined pressure. In addition, an organic film such as a photoresist film is used as a mask to selectively form the silicon oxide film. Although the silicon oxide film containing fluorine and formed on the basis of the present invention is formed at a very low temperature of 30.degree. C., this silicon oxide film has a water content smaller than that of a silicon oxide film formed at a temperature of 250.degree. C. in a conventional method.

The method includes steps which eliminate the apparent thickness of the transparent medium through which the finely cut-up material is seen, thus enhancing the stone-like appearance.

Abstract: A method for applying silicone oil to a back end of an injection needle having a hub with a center hole and a cannula inserting in the center hole, in which the cannula has a front end with a sharp bevel and a back end with another sharp bevel and the back end terminates within the hub. The method comprises allowing silicone-containing-liquid to continue to overflow at a constant rate of flow from a top end of a rising pipe having an inner diameter larger than an outer diameter of the cannula and an outer diameter smaller than an inner diameter of the hub, and concurrently dipping the back end into silicone-containing-liquid at the top end of the rising pipe. Silicone with no foreign matter can be applied to the injection needle while preventing adhesion of silicone containing liquid to the hub. The apparatus used for carrying out the method is also disclosed.

The articles comprise a flexible substrate and a fabric conditioning composition, wherein the fabric conditioning composition is distributed unevenly on the substrate so as to form a visual contrast between areas containing relatively high amounts of conditioning composition and areas containing either no conditioning composition or relatively low amounts thereof.

Abstract: Method for pressing a material into a through-hole or blind-hole in a substrate. The material is disposed on the surface of the substrate. An environment is provided permitting the material to flow for example by heating the material to the glass transition temperature or above. Thereafter pressure is applied causing the material to flow, first coating the sidewall of the hole and on the continued application of pressure the material flows to completely fill the hole. The resulting substrate can have a substantially planar surface having holes with the periphery coated with or completely filled with the material. The material is preferably a thermoplastic polymeric material such as a polyimide and a perfluorinated polymer.

Abstract: An improved method of inserting a liner into a metallic pipeline is disclosed. The liner is formed from a plurality of concentric tubes that are enveloped in a flexible, expansible, tear resistant material. When the concentric tubes are pulled into the pipeline, the tear resistant material provides protection against tearing of the tubes by burrs, snags or other imperfections on the inside of the metallic pipeline. The tear resistant material may be a fabric, woven material or mesh. Materials having a structure that permits escape of fluid entrapped during subsequent expansion of the concentric tubes on formation of the liner are preferred. The method permits the lining of pipeline sections that have bends, loops or the like, while protecting the liner from tearing during insertion into the pipeline.

The silane and/or siloxane comprises a silicon moiety, a group having fire retardant properties and a group capable of permitting chemical attachment of the composition to the material. A catalyst may be added to the composition to increase the rate of the chemical attachment of the composition to the material. The material is treated with this composition producing a fire retardant article. The composition also imparts water resistance to the treated material.
