Abstract: An X-ray apparatus, in particular a dental X-ray apparatus, includes an X-ray radiation source for generating X-ray radiation to be directed at an object to be investigated, for example, a patient's tooth or jaw. The apparatus has an optical device through which an aiming device, for example, an additional visible pilot radiation generated by a further light source, is directed substantially parallel to the X-ray radiation at the object to be investigated to facilitate the positioning of the X-ray head.

Abstract: A dental X-ray system includes a radiation source used to produce X-rays and disposed in an X-ray head. The system has an electronic sensor used to detect X-rays. The sensor can be detachably connected to a central unit of the X-ray system by a plug-in connection. The electronic control system for the sensor is integrated into a plug connected thereto by an external connection cable and is associated with the sensor, thereby enabling a simple exchange between two sensors. The system can include several sensors that can be operated parallel to each other.

Abstract: Liquid samples containing for example differerent combinations of DNA and markers are subjected to various processing steps, for examle exposure to different temperature baths. A flexible band is used that contains a series of cavities arranged along a longitudinal direction of the flexible band. The liquid samples are inserted into the cavities and the band is subsequently fed through a succession of processing stations. The band extends through the stations when the processing steps of the stations are applied. By advancing the band the samples are subjected to successive processing stages. At the end of the process the band may be disposed of, for eexample after extracting the samples.

Abstract: The invention provides a method for increasing the usable surface area of a semiconductor wafer having a substantially planar surface and a thickness dimension at right angles to said substantially planar surface, the method including the steps of selecting a strip thickness for division of the wafer into a plurality of strips, selecting a technique for cutting the wafer into the strips at an angle to the substantially planar surface, in which the combined strip thickness and width of wafer removed by the cutting is less than the thickness of the wafer, cutting the wafer into strips using the selected technique and separating the strips from each other.

Abstract: An electronics unit includes a low multi-point metallic mount on which an insulating layer is arranged. A conductor track system is arranged on the insulating layer and electronic power components are arranged on the conductor track system. The insulating layer is a sintered electrically insulating polymer layer on which the conductor track system, which comprises a sintered glass frit with a noble metal filling, is arranged.
