Abstract: A fastening unit for connecting a heat-generating body to a heat sink is provided. The fastening unit includes a retaining pin and a retaining element wherein the retaining pin is connected to a retaining head. The retaining pin extends through the retaining element and the retaining head contacts the retaining element. The retaining element is engageable upon a body of the heat sink so as to retain same in a fastening direction of the retaining pin. The retaining element is engageable laterally on the body of the heat sink, the retaining element having, on a side thereof for facing the body of the heat sink, a retaining groove extending in a longitudinal direction perpendicular to the fastening direction. In an assembled state for the fastening unit, at least one groove surface of the retaining groove of the retaining element contacts the body of the heat sink.

Abstract: The invention relates to a fastening unit (10) for connecting thermally stressed components to each other, particularly a heat-generating body (44) having a heat sink (42), comprising a retaining pin (12) and a retaining element (16), wherein the retaining pin (12) is connected to a retaining head (14), the retaining pin (12) extends through the retaining element (16), the retaining head (14) contacts the retaining element (16), and the retaining element (16) engages on the body (44) or heat sink (42) and retains it in a fastening direction (26) of the retaining pin (12).

Abstract: Substrate having a silver-ion containing titanium oxide coating having a silver content of greater than or equal to 0.2 of Ag/l of Ti to less than or equal to 0.4 of Ag/l of Ti, wherein the coating is X-ray amorphous and the hydrophobicity of the coating can be reduced persistently by illumination.

Abstract: Disclosed is a method for producing an implant coating that has a defined toxicity. The method is characterized by the following steps: i. a sol is produced from a biotoxic solution containing precious metal ions and a precursor solution for a titanium oxide; ii. an implant is coated by applying the sol in a sol-gel process; iii. the coating is pyrolyzed and sintered without admitting any light, the precious metal ion concentration in the dried coating ranging from 10 to 60 percent relative to the total weight of the dried coating; and iv. at least subareas of the coating produced without admitting any light are illuminated in order to reduce the toxicity of the dried coating to a predetermined measure.

Abstract: A method for measuring a flow rate of a medium through a measuring tube which is penetrated by a constant magnetic field orthogonal to a flow direction and in which an electrical voltage building up in the medium is sensed by electrodes, insulted with respect to the medium and located on an outer wall of the measuring tube in a plane orthogonal to the flow direction of the medium, in which the capacitance of at least one capacitive unit is formed by the electrodes, and a measuring tube interior area and a charge change brought about by a change to the at least one capacitive is determined, and from this a voltage is established which is determinative of the flow rate of the medium through the measuring tube.
