Abstract: A cooling device for cooling a light-emitting semiconductor device, such as a LED device (20), comprises a ceramic plate (15) having coolant-conveying channels (12) incorporated therein. The ceramic plate (15) is adapted for forming an integral part of the optical system of the light-emitting semiconductor device (20) and to cool a light-emitting portion (26) of the light-emitting semiconductor device (20). A method of forming a cooling device comprises the steps of forming a charge of ceramic particles, embossing the charge with a stamp to form coolant-conveying channels in the charge, hardening the charge, and providing a cover on top of the channels to seal them.

Abstract: The invention relates to a ferroelectric device (10) with a body (11) comprising a substrate (1) and a ferroelectric layer (2) provided with a connection conductor (3) on a side facing away from the substrate (1), which ferroelectric layer contains an oxygen-free ferroelectric material (2) and is used to form an active electrical element (4), in particular a memory element (4). Such a device forms an attractive non-volatile memory device. In accordance with the invention, a conductive layer (5) is present between the substrate (1) and the ferroelectric layer (2), which conductive layer forms a further connection conductor (5) of the ferroelectric layer (2), and the active electrical element (4) is obtained as a result of the fact that the ferroelectric layer (2) forms a Schottky junction with at least one of the connection conductors (3, 5).

Abstract: An articulated arm for the alignment or a capturing device for optically capturing an object to be placed on a support surface, has—as a conventional double parallelogram arm—a base part, a top part, an articulate part and two pairs of rods which connect the base part or the top part to the articulated part. The articulated arm furthermore has a shaft which is rotatably fastened to the top part and has an operative mechanical connection to one of the rods pivotably fastened to the top part. This operative connection results in a rotation of the shaft relative to the top part on pivoting of the rod.

Abstract: A device for optically capturing objects has a support surface (1) for an object, a light source (4) and a capturing means (5) for capturing the positioned object and for converting the image of the captured object into electrical signals. The light source (4) and the capturing means (5) are each arranged in a specific position relative to the support surface (1). The support surface (1) has a section (6) provided with a curvature determined by the two positions. Said section is arranged so that illuminating beams (2, 3) emitted by the light source can be reflected by the support surface (1) in the direction of the capturing means 5 substantially only in a diffuse manner.

Abstract: An articulated arm (1) according to the invention, for the alignment of a capturing means (2) for optically capturing an object to be placed on a support surface (3), has—as a conventional double parallelogram arm—a base part (4), a top part (7), an articulated part (10) and two pairs of rods (5, 6, 8, 9) which connect the base part (4) or the top part (7) to the articulated part (10). In contrast to the prior art, an articulated arm (1) according to the invention furthermore has a shaft (11) which is rotatably fastened to the top part (7) and has an operative mechanical connection to one of the rods (9) pivotably fastened to the top part (7). This operative connection results in a rotation of the shaft (11) relative to the top part (7) on pivoting of the rod (9).

Abstract: An angular contact ball bearing is configured so that the inner bearing ring (6) comprises two spaced apart points of contact, B and C, and the outer bearing ring comprises one point of contact A, the point of contact C of the inner bearing ring (6) being formed only after a tilting of the inner bearing ring (6). Due to this third point of contact C, a tilting of the inner bearing ring is almost completely prevented.

Abstract: An improved solar cell structure is described wherein the cell's front region is provided with a plurality of raised structures, each structure comprising a multilayer of a highly doped region and a high-low junction. On these raised structures sit the solar cell's conductive grid. By emplacing the multilayer structure directly underneath the front region metallized conductive grid, the efficiency losses which would have been present had the highly doped region extended entirely or partially across the front layer, are avoided and the high surface recombination velocity associated with the grid is masked.

Abstract: Pharmaceutical dosage unit compositions for the treatment of tachycardia and angina pectoris, which contain 2-(2',6'-diethylphenyl-amino)-1,3-diazacyclopentene-(2) or a non-toxic, pharmaceutically acceptable acid addition salt thereof as an active ingredient; and a method of slowing the heart rate therewith.
