20120237745 | CERAMIC OR GLASS-CERAMIC ARTICLE AND METHODS FOR PRODUCING SUCH ARTICLE - The present invention relates to a method of producing a (shaped) ceramic or glass-ceramic article, involving the steps of: (a) providing a powder or a powder mixture comprising ceramic or glass-ceramic material, (b) depositing a layer of said powder or powder mixture on a surface, (d) heating at least one region of said layer by means of an energy beam or a plurality of energy beams to a maximum temperature such that at least a part of said ceramic or glass-ceramic material in said at least one region is melted and (e) cooling said at least one region of said layer so that at least part of the material melted in step (d) is solidified, such that the layer is joined with said surface in said at least one region. The invention also relates to ceramic or glass-ceramic articles and their use. | 09-20-2012 |
20120187439 | SOLAR CELL ASSEMBLY AND ALSO SOLAR CELL ARRANGEMENT - The invention relates to a light-absorbing or light-emitting solar cell assembly and also a solar cell arrangement which is constructed from 2 to 10,000 of the solar cell assemblies according to the invention. | 07-26-2012 |
20120172587 | METHOD FOR PRODUCING POLYSACCHARIDE ESTERS OR POLYSACCHARIDE MIXED ESTERS - The invention relates to a method for producing polysaccharide esters or polysaccharide mixed esters, in which a polysaccharide or a modified polysaccharide is converted with at least one esterification reagent and at least one halogenide component, an imidazole compound which is generated in situ being used as catalyst. | 07-05-2012 |
20110296563 | FLEXIBLY DISPLACEABLE COUPLING DEVICE FOR ACOUSTICALLY EXCITED ATOMIC FORCE MICROSCOPY WITH ACOUSTIC EXCITATION OF THE SAMPLE - A coupling device for an atomic force microscope with acoustic sample excitation includes a sound generator, in particular an ultrasonic test head, and designed for coupling of sound waves generated using the sound generator into a sample body for the acoustic excitation of the sample body, where the coupling device has a liquid reservoir fillable and/or filled with a liquid in its inner space; the lower side of the sample body can be arranged and/or is arranged laterally displaceably on the liquid reservoir; the end of the sound generator formed for coupling the sound waves into the sample body is arranged in the inner space of the liquid reservoir and/or that sound waves can be coupled into the inner space with this end; and the spatial section of the inner space of the liquid reservoir disposed between this end and the lower side of the sample body is completely fillable and/or filled with the liquid. | 12-01-2011 |
20100265485 | Flexibly Deformable Holding Element For Substrates - Flexibly deformable holding elements operate such that substrates can be held in a fixed manner at a surface of the holding element electrostatically or also by means of negative pressure and planar positional deviations or unwanted deformations can be compensated simply and reliably, where at least one cut-out having an opening arranged at the rear side is formed at the rear side of the holding element which is disposed opposite the surface, and an actuator is arranged there exerting compressive forces or pulling forces for a widening or narrowing of the cut-out and/or for a deformation of the holding element. | 10-21-2010 |
20100262420 | AUDIO ENCODER FOR ENCODING AN AUDIO SIGNAL HAVING AN IMPULSE-LIKE PORTION AND STATIONARY PORTION, ENCODING METHODS, DECODER, DECODING METHOD, AND ENCODING AUDIO SIGNAL - An audio encoder for encoding an audio signal includes an impulse extractor for extracting an impulse-like portion from the audio signal. This impulse-like portion is encoded and forwarded to an output interface. Furthermore, the audio encoder includes a signal encoder which encodes a residual signal derived from the original audio signal so that the impulse-like portion is reduced or eliminated in the residual audio signal. The output interface forwards both, the encoded signals, i.e., the encoded impulse signal and the encoded residual signal for transmission or storage. On the decoder-side, both signal portions are separately decoded and then combined to obtain a decoded audio signal. | 10-14-2010 |
20080239446 | MICROMECHANICAL DEVICE WITH TILTED ELECTRODES - A micromechanical device includes a micromechanical functional structure, which can be deflected about a main axis from a rest position, a movable electrode, which is mounted to the micromechanical functional structure, and a fixed electrode, which can be tilted about a tilting axis with respect to the movable electrode in the rest position, wherein the tilting axis is parallel to the main axis or is identical with the main axis. | 10-02-2008 |
