| 20100025590 | COMPUTED TOMOGRAPHY GANTRY ROTOR - A rotor of a gantry of a computed tomography apparatus is produced at least in sections in a differential style from bar-shaped basic elements. Due to the differential style of the rotor, the rotation mass is reduced to a significant degree given a simultaneously maintained rigidity and stability of the rotor | 02-04-2010 |
| 20100025591 | COMPUTED TOMOGRAPHY ROTOR, AND GANTRY EMBODYING SAME - A rotor, and a gantry and a computed tomography apparatus with such a rotor, has recess to accommodate at least one component of an image data acquisition device, and the recess is dimensioned such that the component can be inserted therein in a radial direction proceeding away from a rotation center of the rotor and is positively connected with the rotor by an abutment structure provided on the component, as well as by spot connections. This positive fit thus acts in the direction of the centrifugal forces arising upon rotation of the rotor, such that an ejection of the component from the rotor is effectively prevented even given a failure of the spot connections (for example bolt connections) between the rotor | 02-04-2010 |
| 20100027757 | RIGID COMPUTED TOMOGRAPHY ROTOR AND METHOD FOR THE MANUFACTURE THEREOF - A rotor for a gantry of a computed tomography apparatus, as well as a manufacturing method for such a rotor. The rotor according to the invention is produced at least in segments from a composite material with polymer matrix that is reinforced with fibers. The rotor thus has a high strength and rigidity, such that the deformation limits to achieve a sufficiently good image quality with simultaneously low structural volume and low weight are not exceeded, even at high rotation speeds. | 02-04-2010 |
| 20100027758 | COMPUTED TOMOGRAPHY ROTOR RIGIDIFIED BY A METAL MATRIX MATERIAL - A computed tomography apparatus according to the invention ha a rotor that is produced at least in segments from a composite material with metal matrix reinforced with particles. Composite materials with a polymer matrix reinforced with particles have high specific strength properties and rigidity properties with simultaneously low material usage, such that high rotation speeds of the rotor can be achieved without negatively affecting the image quality in generated tomographical images. | 02-04-2010 |
| 20100027759 | COMPUTED TOMOGRAPHY ROTOR RIGIDIFIED BY A COMPOSITE MATERIAL WITH SHAPED BODIES THEREIN - In a rotor for a gantry of a computed tomography apparatus, as well as a manufacturing method for such a rotor, the rotor is manufactured as to contain shaped bodies (at least in segments of the rotor) produced from a composite material. By the integration of such shaped bodies with high strength and rigidity, the rotor can be stabilized in a targeted manner in the regions in which high stress values that arise upon rotation of the rotor. | 02-04-2010 |

| 20100075098 | PYRIDINONE BASED AZO DYES AND THIER METAL COMPLEX SALTS - The present invention relates to pyridinone based azo dyes and/or of anionic azo metal complex dye salts made thereof with cationic basic yellow dyes, which are characterized by an unsaturated bond in beta-position to the endocyclic N atom of the pyridinone, and to their use in optical layers for optical data recording, preferably for optical data recording using a laser with a wavelength up to 450 nm. | 03-25-2010 |
| 20110012072 | Use of Hydrophobic Solvent-Based Pigment Preparations in Electronic Displays - The invention relates to the use of a pigment preparation as a dye for producing a colored optical image in an electronic display, said pigment preparation containing (A) at least one organic and/or inorganic pigment, (B) at least one solvent-soluble or solvent-dispersible polymeric dispersant, (C) at least one aldehyde resin or ketone resin, (D) optionally further additives common for producing solvent-containing pigment preparations, and (E) at least one hydrophobic solvent. | 01-20-2011 |
| 20110041913 | Use of Hydrophobic Solvent-Based Pigment Preparations in Electronic Displays - The invention relates polysilazane-containing coatings for increasing the light permeability of sun-facing covers of solar cells. The coating for surfaces contains at least one polysilazane of formula (1) —(SiRR′R″—NR′″1)n— (1), wherein R′,R″,R′″ are the same or different or represent an optionally substituted alkyl, aryl, vinyl or (trialkoxysilyl)alkyl group, n being an integer and n being chosen in such a manner that the perhydropolysilazane has a number average molecular weight of 150 to 150,000 g/mol, a solvent and a catalyst. The cured coating has a thickness of at least 0.50-10 micrometer, preferably 0.2 to 5 micrometer, especially preferred 0.5 to 1.5 micrometer. It is especially suitable as transmission-promoting coating for use in sun-facing covers of solar cells. | 02-24-2011 |
