20100139841 | METHOD FOR THE MANUFACTURE OF A CERAMIC COMPONENT - The invention relates to a method for the manufacture of a ceramic component of desired final geometry using at least a cellulose-containing semi-finished moulded part, which is pyrolysed in non-oxidizing gas atmosphere. In order to manufacture complex components, it is suggested that at least two semi-finished moulded parts are firmly joined either in raw form or after at least partial carbonisation. The joined moulded parts are subsequently machined to achieve the desired final geometry or a geometry corresponding to the desired final geometry plus the machining allowance. Then, the carbon parts are available after carbonisation of the moulded parts in non-oxidizing atmosphere. Alternatively, these can be converted into a CMC composite material in a non-oxidizing gas atmosphere by a metal infiltration process with simultaneous reactive joining of at least two moulded parts. | 06-10-2010 |
20090110847 | Apparatus and Method for Producing Light-Emitting Elements With Organic Compounds - The invention relates to an apparatus and a method for the manufacture of light emitting elements comprising organic compounds. These elements are provided with organic light emitting diodes and can be displays or also lighting elements having such light emitting diodes. It is the object of the invention to reduce the effort for the manufacture with respect to the costs and to the time effort. In this connection, already pretreated substrates are further processed in a continuous vacuum coating plant. An electrode is formed on such a substrate and at least one layer of an organic compound which is suitable for the emission of light should be deposited over said electrode. The deposition should take place with different angular distributions. Shadow masks are used for this purpose. The adaptation of the angular distribution in the deposition can take place by varying the spacing of the shadow mask from the substrate and/or of the base pressure of sources for the deposition of the top electrode and of the organic layer(s). | 04-30-2009 |
