    摘要： A hydraulic adjustment device for variable-pitch propellers of turbo-engines comprise a shaft for driving the variable-pitch propeller. A plurality of transmission elements for feeding and draining, as well as for guiding a hydraulic fluid is disposed in the shaft. A rotation passage for the hydraulic fluid is disposed in a chamber, which surrounds the shaft. The chamber is disposed adjacent to the variable-pitch propeller and is in fluid communication with a transport medium. The hydraulic fluid is harmonious to the transport medium.

    摘要： A method for producing a semiconductor arrangement of two antiparallel connected diodes comprising a semiconductor body which includes a base region of one conductivity type and a zone adjacent each side of the base region. Each zone forms a pn-junction with the base region and thus a diode structure and is offset with respect to the other zone. The major surfaces formed by each base region and one of the two zones are provided with a contact metal coating so as to electrically connect the two diode structures. In accordance with this method, a layer sequence of three zones with pn-junctions therebetween is formed by diffusion on a semiconductor starting disc. Then, mutually parallel recesses are produced with the aid of masking in each major surface of the disc according to a strip-shaped structure, offset with respect to that of the other major surface, by removing material to beyond the respective pn-junction. Both major surfaces are metallized and the disc is divided along the recesses into semiconductor arrangements.
