Inventor: SANG JEAN VICTOR
IPC: C04B41/45
Filed: 1990-01-11
Abstract: Process for coating discrete particles (preferably ceramic particles) with metal compounds, namely metal oxides and metal nitrides. The process comprises forming a solution of an organometallic compound in a substantially anhydrous solvent that is substantially immiscible with water at ambient temperature, coating the particles with the solution and maintaining the particles substantially separate from each other while removing the solvent from the coating solution, e.g. by atomizing a slurry of the particles and the solution into a volume of heated gas. The resulting particles coated with the organometallic compound are then heated to a temperature at which the organometallic compound is converted to the corresponding metal oxide. If the final coating is to consist of a metal nitride, a carbon precursor (e.g. petroleum pitch) is also dissolved in the anhydrous solvent before the particles are coated, and then the oxide formed in the heating step is converted to the nitride by further heating at high temperature in the presence of nitrogen or a nitrogen precursor. The process is capable of producing ceramic particles coated with a uniform, continuous, non-porous layer of metal oxide or nitride suitable for use, for example, as reinforcements for ceramic or metallic composite materials.

Abstract: A system and method for selectively simulating logic circuit designs in which a data tables generator (12) receives information from a schematic entry program (10a) or netlist entry file (10b) and produces data tables for use by a simulator (14). A designer provides inputs to the data tables generator from a schematic entry program or a netlist entry file. The data tables generator (12) generates from the information received a table of used integrated circuits and a table of their connections. A simulator (14) then receives the output from the data tables generator (12) and produces a design simulation program table that executes integrated circuit model subroutines stored in an integrated circuit model reference library (4) and netlist subroutines stored in a netlist connectivity table (18). The system may also be used for testing logic circuits on a printed circuit board by capturing signals from a potentially defective logic section of the printed circuit board and feeding them into test points of the integrated circuit simulated by the computer simulator.
