    摘要: The invention concerns a welding machine for electrically resistance welding together, to form a mesh, at their points of intersection in a mesh production plane, two crossed groups of parallel wires. The machine incorporates at least two pairs of opposed cooperating welding electrodes, one of said pairs being arranged on each side of the mesh production plane. A pair of transformers have their primary windings connected in series and each pair of said electrodes are connected to the secondary winding of one of the transformers in such a way that in operation the welding current will flow through the electrodes and through the secondary windings of the transformers in series.

    摘要: An apparatus for switching an alarm-signalling device which is connectable to a protective circuit so as to signal an alarm when a door or the like is displaced from its closed position in a jamb or the like by an intruder, in which the switching apparatus is mounted in the door and jamb or the like. The switching apparatus includes a switch which is connectable to the protective circuit, which is mounted in a housing which is installable so as to be recessed in the jamb, and a magnet which is magnetized such that opposite faces thereof define poles of opposite polarity, which is mounted in a housing which is installable so as to be recessed in the side of the door and disposed opposite the switch when the door is closed in the jamb. The switch includes a pair of contacts disposed in one end of the housing, a metal plate mounted in the other end of the housing, and a magnet which is reciprocally movable in the housing, which is magnetized such that opposite faces thereof define poles of opposite polarity, and which is disposed so that one pole thereof faces the metal plate, which pole is of the same polarity as the pole of the external magnet which is disposed opposite the portion of the housing in which the metal plate is mounted when the external magnet is positioned opposite the housing, so that the switch magnet is repelled by the external magnet when the external magnet is so positioned such that the switch magnet bears against the contacts to compress the contacts in a rolling and wiping action to close the protective circuit; when the door and external magnet are displaced from their closed position in the jamb, the switch magnet is attracted to the metal plate such that the contacts are released to open the protective circuit which actuates the alarm-signalling device.

    摘要: A system enhances speech by detecting a speaker's utterance through a first microphone positioned a first distance from a source of interference. A second microphone may detect the speaker's utterance at a different position. A monitoring device may estimate the power level of a first microphone signal. A synthesizer may synthesize part of the first microphone signal by processing the second microphone signal. The synthesis may occur when power level is below a predetermined level.

    摘要: A semiconductor device includes a semiconductor body with a base layer and a field shaping zone of a first conductivity type. The base layer extends parallel to a back surface of the semiconductor body in a central portion and into an edge portion that surrounds the central portion. The field shaping zone is formed in the edge portion and has a maximum dopant concentration exceeding at least three times a maximum dopant concentration in the base layer. A back side metal structure directly adjoins the back surface in the central portion and extends over the edge portion. A dielectric structure is between the back side metal structure and the field shaping zone. Leakage current mechanisms reducing the reverse blocking capabilities are reduced.

    摘要: A fastening arrangement for a wall-supported and floor-supported element of an interior fitting on the side wall of a rail vehicle is provided. A C-section rail is arranged on the side wall for receiving sliding blocks to which the element is releasably screwed. The element is provided with a shaped part which at least partially encompasses the C-section rail and extends in the longitudinal direction of the C-section rail. The shaped part is supported on at least both of its ends on the outside of the C-section rail for absorbing vertical loads and moments, and, for absorbing the longitudinal and transverse forces acting on the shaped part, the shaped part is connected to at least one sliding block which is arranged between both ends of the shaped part in the C-section rail.
