    摘要: The pressure sensor consists of a substrate and a diaphragm joined together around the periphery so as to form a chamber. The surface of the diaphragm facing away from the substrate is exposed to a medium whose pressure is to be measured. To protect the diaphragm against corrosion or abrasion, the diaphragm surface exposed to the medium is covered with a layer of silicon carbide, preferably by chemical vapor deposition.

    摘要: The substrate (12) and/or the diaphragm (11) of the pressure sensor (10) are made of ceramic, glass, or a single-crystal material. The side of the diaphragm (11) facing the substrate (12) is covered with a layer of silicon carbide, niobium, or tantalum which, in turn, is covered with a protective layer (21) and serves as one capacitor electrode (14). The side of the substrate (12) facing the diaphragm (11) is covered with at least one additional layer of any one of said materials which, in turn, is covered with an additional protective layer (22) and serves as the second capacitor electrode (15). Substrate (12) and diaphragm (11) are soldered together by a formed part of active solder (20) which also serves as a spacer.This pressure sensor can be manufactured in a single soldering step. The maximum load capacity of the diaphragm is determined not by the strength of the joint, but only by the strength of the diaphragm material. The pressure sensor can be used at higher temperatures than pressure sensors with glass-frit joints.

At least one first trench is at least partly filled with insulation material proceeding from the first side in the direction toward the second side into the semiconductor body. The at least one first trench is produced between a first semiconductor body region for a first semiconductor device and a second semiconductor body region for a second semiconductor device. An isolating trench extends from the first side of the semiconductor body in the direction toward the second side of the semiconductor body between the first and second semiconductor body regions in such a way that at least part of the insulation material of the first trench adjoins at least a sidewall of the isolating trench. The second side of the semiconductor body is partly removed as far as the isolating trench.

    摘要: In a device for ascertaining the actual feed transmittted by an feed devicef an industrial sewing machine to a material to be sewn, in which the number of the threads moved across a sensor arrangement is counted and the feed is calculated from the previously detected thread density, it is provided, for obtaining an exact thread count which is as independent as possible of the orientation of the sewn web, to place ahead of the photocell (10) of the sensor arrangement a rotating slit diaphragm (7) with at least one radially extending parallel limited slit (8). Preferably a second, rotationally adjustable, but fixed slit diaphragm (5) is provided, having slits (6) opening across a set angular sector, the rotatitng slit diaphragm (7) having a larger number of slits (8). Because of this the required rpm of the slit diaphragm (7) can be reduced. To avoid errors caused by the pattern of the material it is possible to operate in the relatively longer wave infrared spectrum.

    摘要: The invention provides an arrangement for determining the speed and rotor position of an electric machine, which arrangement consists of a tachometer generator having a permanent-magnet-excited rotor and a coaxially arranged rotor position transmitter which has a rotor body equipped with permanent magnets. Around the circumference of the rotor body magnetic-field sensitive sensor elements are arranged. A compact assembly of the tachometer generator and rotor position transmitter without detrimental mutual interference is possible by the provision that first permanent magnets magnetized in the tangential direction are arranged centered to the pole gaps of the tachometer generator rotor at the rotor body in such a manner that the sides of two adjacent permanent magnets facing each other have the same polarity as the magnet pole extending between the respective pole gaps of the tachometer generator rotor. Furthermore at least one second permanent magnet magnetized in the direction of an axis of rotation is arranged on the side of the rotor body adjacent to the tachometer generator rotor, centered relative to each two first permanent magnets in such a manner that its side facing the tachometer generator rotor has the opposite polarity (N or S, respectively) as the opposite magnet pole of the tachometer generator rotor.
