Abstract: The invention relates to a micro cooling element (1) with a mounting surface (2) for a component to be cooled, in particular a semiconductor component, which has within it a micro cooling structure (3) which is connected by connection channels (4) to at least one inflow opening (4a) and at least one outflow opening (4b) by means of which a cooling medium can be supplied to the micro cooling structure (3) or be discharged from the latter, and which is characterized in that it is formed from at least two different powdery and/or liquid, in particular metallic and/or ceramic, materials or material mixtures (10) while maintaining a monolithic structure, wherein regions of different stresses (I, II) of the micro cooling element (1) are built by a powdery and/or liquid, in particular metallic and/or ceramic materials or material mixtures (10) being adapted to the stress respectively. The invention further relates to an apparatus and a process for producing a micro cooling element according to the invention.

Abstract: The invention relates to a micro-scale cooling element (1) having a mounting surface (2) for a constituent part, in particular a semiconductor component, that is to be cooled, which element is configured, in particular, cuboidally and has in the interior a micro-scale cooling structure (3) that is connected via connecting conduits (4) to at least one inflow opening (5) and at least one outflow opening (6) through which a cooling medium is conveyable to and dischargeable from the micro-scale structure (3), the micro-scale cooling element having a monolithic structure.

Abstract: The invention provides a process for the preparation of a compound of formula (I) in particular, wherein a compound of formula (II) is reacted with a dialkylsulphate. R1 is C1-C4haloalkyl; R2 is optionally substituted alkyl, optionally substituted aryl or optionally substituted heteroaryl; and R3 is methyl or ethyl.

Abstract: A method reduces the noise in the drive train of a motor vehicle having an automatic transmission or a manual transmission with a controllable oil pressure supply and/or automatic starting clutch. An engine sided drive unit is connected to the transmission input shaft by way of a spline connection, wherein noises in the drive train are caused by a clearance fit in the spline connection between the engine sided drive unit and the transmission input shaft. The transmission control is adapted for reducing the noise when in neutral.
