The invention relates to fluid paths in etchable materials. Fluid paths are formed by forming a cavity through a substrate material with a first dry removal process to produce a first surface of the cavity. The first surface of the cavity is associated with a first roughness. The first surface of the cavity is etched with a second wet removal process to reduce the first roughness and produce a second roughness associated with the first surface of the cavity. A coating is applied to the first surface of the cavity to produce a second surface to improve wettability of the first or second surface of the cavity, reduce in size or number gas nucleation sites in the first or second surface of the cavity, reduce the amount of debris associated with the first roughness carried by the fluid flow, and/or improve hydrophilicity of the first or second surface.

A coil for a magnetic resonance device is provided. The coil includes a cylindrical coil insulating frame with at least one winding groove running around its circumference, at least one coil conductor wound into the winding groove around the coil insulating frame, and one electrically-insulating insulator lining the winding groove and insulating the coil insulating frame and the coil conductor from each other. The insulation includes a number of molded insulating segments that line the winding groove, supplementing each other to form a circular ring which matches the cross-sectional shape of the winding groove.

The invention relates to 3,4-dihydro-thieno[2,3-d]pyrimidin-4-one derivatives which are substituted in position 3 by 5-membered heteroaryl which may be fused to an aryl or heteroaryl radical, where the heteroaryl and, if appropriate, the fused aryl or heteroaryl radical may have 1, 2 or 3 substituents selected independently of one another from C1-5-alkyl, C1-5-alkoxy, C1-5-alkylthio, halogen, CN, halo-C1-5-alkyl, halo-C1-5-alkoxy, hydroxy, —NH2, —N(R6)2, —NH(R6), aryl, aryloxy, aralkyl, aralkyloxy and heteroaryl, where the substituents aryl, aryloxy, aralkyl, aralkyloxy and heteroaryl may have 1, 2 or 3 substituents selected independently of one another from C1-5-alkyl, C1-5-alkoxy, C1-5-alkylthio, halogen, CN, halo-C1-5-alkyl, halo-C1-5-alkoxy, hydroxy, —NH2, —N(R6)2 and —NH(R6). The preparation and use of these derivatives, especially for therapeutic purposes, e.g. for the treatment of depressions, are likewise described.

The device comprises a device (2) for creating an essentially linear target (4) in an evacuated space where laser beams (1) are focused, the target being suitable for interacting with the focused laser beams (1) to emit a plasma emitting radiation in the extreme ultraviolet. A receiver device (3) receives the target (4) after it has interacted with the focused laser beams (1), and a collector device (110) collects the EUV radiation emitted by the target (4). The focusing elements (11) for focusing the laser beams on the target (4) are arranged in such a manner that the laser beams (1) are focused on the target (4) laterally, being situated in a common half-space relative to the target (4) and being inclined at a determined angle lying in the range about 60° to about 90° relative to a mean collection axis (6) perpendicular to the target (4). The collector device (110) is disposed symmetrically about the mean collection axis (6) in the half-space containing the laser beams (1) focused on the target (4) and inside a conical space (8) centered on the mean collection axis (6) with a vertex situated at the target (4) and a half-angle at the vertex that is less than the angle of inclination of the focused laser beams (1) relative to the mean collection axis (6). The device is suitable for use as a source for EUV radiation in lithography for fabricating integrated circuits.

A gas detector for x-rays can be easily taken apart for repair and service. The gas detector has plate-shaped electrodes which are plugged into spring contacts, the spring contacts being connected in groups to a conductor foil which is connected by means of contact projections to a printed circuit board. The printed circuit board carries electronic components for processing detector signals from the electrodes.

In an x-ray detector of the type employing a gas-filled chamber containing a number of electrode plates for detecting ionization event caused by the interaction of x-ray photons with the gas, a number of detector cells are formed, each detector cell containing two electrode plates disposed in a plane in succession in the direction of propagation of an incoming x-ray beam. In order to permit the acquisition of different spectral ranges, the electrical signals from the electrode plates are respectively conducted out of the chamber. The electrode plates are plugged into spring contacts and are connected group-by-group to a conductor foil. Each conductor run within the conductor foil has a contact projection for making electrical contact between the conductor foil and a printed circuit board, which carries electronic components for processing the detector singles.
摘要:
An apparatus is provided for producing metallic heat exchanger tubes having a heat exchange surface that is increased by fins. A rotating tube has helically wound on its outer surface a strip that forms the fins, with this strip being fed to the tube surface under tension, and with the bottom edge of the strip being welded to the tube. The contact surface that exists between the tube and the bottom edge of the strip, and that extends helically on the surface of the tube, is fused exclusively at the surface of the tube with a laser beam that is directed in the region where the strip runs onto the surface of the tube, and that fuses a portion of the tube surface that in the axial direction of the tube corresponds at least to the width of the bottom edge of the strip and in the circumferential direction corresponds approximately to the same amount. At the same time, the laser beam fuses the bottom edge of the incoming strip in the region where the strip runs onto the surface of the tube. The fused surface areas are joined in a gap-free manner as the strip runs onto the tube, and are connected to one another to form a continuous, residual-gap-free welding.
