Abstract: An object of the present invention is to easily eliminate fumes inside a chamber, so as to improve a positional accuracy of irradiation with a light beam and a machining accuracy in a method for manufacturing a three-dimensional shaped object. A stacked-layers forming device 1 includes a powder layer forming unit 3, a light beam irradiating unit 4, a base 22 which is fixed and on which a powder layer 32 is formed, a lifting/lowering frame 34 which surrounds the circumference of the base 22 and is freely capable of being lifted and lowered, a cover frame 36 which has a window 36a allowing transmission of light beam in its top surface, and whose bottom surface is opened, and which is disposed on the lifting/lowering frame 34 to form a chamber C, and a gas tank 71 for supplying an ambient gas. The lifting/lowering frame 34 is lowered to reduce the volume of the chamber C, so as to discharge fumes generated inside the cover frame 36, which performs replacement with the ambient gas. Since the volume of the chamber C is reduced, it is possible to easily eliminate the fumes, which makes it possible to improve the positional accuracy of irradiation with the light beam L, and the machining accuracy.

Abstract: In an alloy based on titanium aluminides, metal droplets are obtained from a titanium aluminide metal melt. The metal droplets are enriched with halogens resulting in halogen-enriched titanium aluminide metal droplets. The alloy is molded from the halogen-enriched titanium aluminide metal droplets by, preferably hot isostatic, pressing. Titanium aluminide powder can be heated in a container, for a predetermined period of time, wherein an atmosphere, enriched with halogens, is or will be provided in the container, so that a halogen-enriched titanium aluminide metal powder is formed, or metal droplets are formed from a titanium aluminide metal melt. The metal droplets are enriched with halogens so that halogen-enriched titanium aluminide metal droplets result. Subsequently, the alloy is molded from the halogen-enriched titanium aluminide metal droplets.

Abstract: A nickel powder with a mean particle size of 0.05 to 1.0 μm, the nickel powder having a thin oxidized layer of nickel on a surface thereof, an oxygen content of 0.3 to 3.0 wt. % and a carbon content of 100 ppm or less per specific surface area of 1 m2/g of the powder, in a weight proportion of carbon to the nickel powder of unit weight. When the powder is used for a conductive paste for forming inner electrode layers of a multilayer electronic component, it enables a decrease in the residual carbon amount after a binder removal process, thereby making it possible to obtain a multilayer ceramic electronic component excellent electrical characteristics and high reliability in which electrode layers excelling in continuity are formed without decreasing the strength and electrical characteristics of the electronic component or creating structural defects.

Abstract: One provides nanocrystalline diamond material that comprises a plurality of substantially ordered diamond crystallites that are sized no larger than about 10 nanometers. One then disposes a non-diamond component within the nanocrystalline diamond material which may comprise an electrical conductor that is formed at the grain boundaries that separate the diamond crystallites from one another. One may also instead react the aforementioned crystallites with a metallic component. The reaction process can comprise combining the crystallites with one or more metal salts in an aqueous solution and then heating that aqueous solution to remove the water. This heating can occur in a reducing atmosphere (comprising, for example, hydrogen and/or methane) to also reduce the salt to metal. Metal or metal carbide nanowires and/or quantum dots are produced as a result of the reaction with the ultrananocrystalline diamond. Such material exhibits thermoelectric and other useful properties.
