Title: Thermally stable dielectric coatings
Inventor: BREMMER JEFFREY NICHOLAS
IPC: H01L21/312
Filed: 1998-06-01
Abstract: This invention pertains to a method for producing thermally stable multi-layer coatings and the coatings produced therefrom.  The multi-layer coating is comprised of a first coating produced from hydrogen silsesquioxane having a thickness of 1.25 to 2.25 µm and a second coating comprising silicon dioxide having a thickness of at least 100 nm.  The method for producing the first coating comprises applying a fillerless hydrogen silsesquioxane resin composition onto a substrate and thereafter heating the hydrogen silsesquioxane resin at a temperature of 150°C. to 500°C. for a sufficient period of time to produce a crack-free coating having a thickness of 1.25 µm to 2.25 µm. The second coating is produced by depositing, preferably by PECVD, silicon dioxide over the first coating at a thickness of at least 100 nm.

Title: Process for the homogenisation of fillers in the stereolithographic preparation of three-dimensional objects
Inventor: STEINMANN BETTINA
IPC: B29C67/00
Filed: 1996-12-10
Abstract: A process for the stereolithographic preparation of a three-dimensional object, wherein the object is built in a container which contains a radiation-curable liquid formulation with fillers by a repeated alternating succession of process steps (a) and (b), wherein in step (a) a layer of the radiation-curable liquid formulation, one limitation of which is the surface of the formulation, is cured using suitable radiation within a surface area which corresponds to the desired cross section of the three-dimensional object to be formed at the level of this layer, and wherein in step (b) a new layer of the radiation-curable liquid formulation is formed on said cured layer, which process comprises homogenising the radiation-curable liquid formulation during said process continuously or discontinuously to such an extent that there is no noticeable change in the filler content of the radiation-curable liquid formulation in the area of that layer with which the cured layer is coated in step (b). This process enables the skilled person, inter alia, to choose his fillers solely according to the purpose envisaged therefor without having to fear technical problems or problems relating to the quality of the sterolithographically produced object resulting from the sedimentation of the fillers during the preparation of the object.

Title: Carbon monoxide concentration reducing apparatus and method, and production method for carbon monoxide-selective oxidation catalyst
Inventor: AOYAMA SATOSHI
IPC: H01M8/06
Filed: 1999-02-25
Abstract: The activity of a carbon monoxide-selective oxidation catalyst is increased, and the temperature range in which the catalyst activity for facilitating a carbon monoxide-selective oxidation becomes sufficiently high is expanded. A CO-selective oxidation unit contains carbon monoxide-selective oxidation catalysts having catalyst metals including platinum and ruthenium. The interior of the unit is divided into a plurality of regions. An upstream-end region has only ruthenium as a catalyst metal. A downstream-end region has only platinum as a catalyst metal. In intermediate regions between these regions, platinum and ruthenium as catalyst metals are present in mixed states. The ruthenium proportion becomes higher toward the upstream-end region. Therefore, the temperature range in which the activity for facilitating the CO-selective oxidation becomes sufficiently high also becomes higher toward the upstream-end region in the CO-selective oxidation unit.
