Abstract: The invention relates to a radiation detector for converting electromagnetic radiation (15) into electric charge carriers. The invention also relates to an X-ray examination apparatus provided with such a radiation detector, and to a method of manufacturing a radiation detector. In order to achieve a small building height of the radiation detector while nevertheless satisfying the same requirements as regards the resetting of the converter arrangement (16, 18) by means of an illumination device (6), it is proposed to provide a supporting layer (8) underneath a glass plate (2a) with a photosensor arrangement (2b), which supporting layer on the one hand provides uniform distribution of the light incident from below and on the other hand imparts the necessary stability to the radiation detector.

Abstract: The present invention relates to a measuring device and a method for contactless detection of an angle of rotation or a torsional rotation. The measuring device includes a first resonator (2) and a second resonator (4). The two resonators (2, 4) have an essentially circular circumference, on which at least one protrusion and/or one recess is disposed. The two resonators (2, 4) are coplanar to one another and are also rotatable relative to one another. In addition, an exciter device (6) for exciting the resonators and a receiver device (6) for measuring a backscattered signal are present. Upon a relative rotation of the two resonators (2, 4) to one another, the resonant frequency changes, which is used as a measure for ascertaining the angle of rotation.

Abstract: A bumper arrangement for a front end or a rear end of an automobile having a bumper cover enclosing the bumper arrangement has a transverse support having a first and a second end. First and second spacer consoles are connected to the first and second ends of the transverse support, respectively. First and second stop plates are connected to the first and second spacer consoles opposite the transverse support. The first and second stop plates secure the bumper arrangement to longitudinal support beams of the car body extending in the longitudinal direction of the automobile. A transverse beam is positioned below the transverse support in a mounted position of the bumper arrangement. Spacer stays connect the transverse beam to the stop plates and are positioned below the spacer consoles. The transverse support and/or the spacer consoles, at least over portions thereof, have two or more deformation areas arranged next to one another in the longitudinal direction of the automobile.

Abstract: A rotor for a commutator machine, having a rotor shaft, a rotor body containing a rotor winding, and a commutator, which has an insulation material body non-rotatably supported on the rotor shaft and has a number of commutator lamellas that are disposed on the insulation material body. Connection lugs that are bent away from the commutator lamellas for connecting connection wires of the rotor winding, in order to use the advantageous ultrasonic torsion welding process to mechanically and electrically connect connection lugs and connection wires without changing the rotor geometry, the insulation material body, is axially supported against the end face of the rotor body oriented toward the end face.

Abstract: The wavelength-converting casting composition is based on a transparent epoxy casting resin with a luminous substance admixed. The composition is used in an electroluminescent component having a body that emits ultraviolet, blue or green light. An inorganic luminous substance pigment powder with luminous substance pigments is dispersed in the transparent epoxy casting resin. The luminous substance is a phosphororous group of the general formula A3B5X12:M, and the luminous substance pigments have particle sizes ≦20 &mgr;m and a mean grain diameter d50≦5 &mgr;m.

Abstract: When a commutator is slipped onto a rotor shaft that is provided with viscous epoxy, a bead of epoxy forms on the connecting end face of the commutator core and can hinder the process of winding the rotor. The novel commutator therefore has a receiving bore (25), which begins at the connecting end face (23) of the commutator and extends coaxially to the longitudinal axis (1) as far as a shoulder (26) and is adjoined by a conical bore (29) tapering toward a through bore (24). The bead (22) of epoxy that forms when the commutator is slipped onto the rotor shaft is completely covered by the receiving bore (25). The commutator is especially suitable for rotors of electrical machines.

Abstract: The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversation element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.

Abstract: A rotor for an electric motor includes a commutator and a rotor shaft with a rotor winding that is contained in a rotor body supported on the rotor shaft in a rotationally fixed manner. The commutator has commutator lamellas that are disposed axially next to one another in the circumference direction with an insulation gap and have connection lugs for attachment of connecting wires of the rotor winding. In a region between the commutator and the rotor body, an additional winding is wound around the connecting wires in order to fix or stabilize the connecting wires. The rotor is provided for electric motors used in vehicle construction.
