    摘要： A process for producing phosphorous-doped silicon monocrystals having a select peripheral depletion or enrichment of dopant atoms along the radial direction of such monocrystals comprises providing a silicon monocrystalline rod homogeneously doped with phosphorous, as by neutron doping, and subjecting such homogeneously doped monocrystalline rod to a peripheral zone melt cycle in a select atmosphere such that the peripheral melt zone depth within the monocrystalline rod is controlled so as to be less than the radius of the rod in accordance with the desired peripheral dopant concentration in the ultimately attained rod.

    摘要： Described are two methods of producing a hollow body, comprised of semiconductor material, especially silicon, by precipitation from a gaseous compound of said semiconductor material upon the surface of a heated carrier body, which after a sufficiently thick layer of semiconductor material has been precipitated, is removed again without damaging said layer. One method is characterized by using a hollow carrier body, open at least at two opposite sides. In one embodiment, prior to the precipitation of the semiconductor material, one of the open sides of the carrier body is covered by a wafer from the same semiconductor material whose shape corresponds to the open side. Thereafter, the semiconductor material is precipitated from the gaseous compound until the desired layer thickness and a gas-tight connection is obtained between the layer and the covering semiconductor material. The second method precipitates a semiconductor layer and thereafter welds a cover on one or both open ends the tube.

    摘要： Disclosed is a agitator (1; 1a-1h), particularly for abrasive media, comprising a support disk (2; 2a-2h) to which agitator blades (3; 3a-3h) are connected substantially perpendicular to the support disk (2; 2a-2h), said blades (3; 3a-3h) being arranged substantially in a radial direction. The support disk (2; 2a-2h) is also provided with a hub that receives an agitator shaft which is preferably motor-driven in a suitable manner. The trailing faces of the blades (3; 3a-3h) of the agitator (1; 1a-1h) and/or the area of the blade connections to the support disk (2; 2a-2h) is/are designed to largely prevent vortex shedding. For this purpose, preferred geometrical measures for the agitator blades (3; 3a-3h), the support disk (2; 2a-2h), and the connection of the blades (3; 3a-3h) to the support disk (2; 2a-2h) are disclosed and described.
