Abstract: A super junction semiconductor device includes a substrate layer of a first conductivity type and an epitaxial layer adjoining the substrate layer and including first columns of the first conductivity type and second columns of a second conductivity type. The first and second columns extend along a main crystal direction into the epitaxial layer and have vertical dopant profiles perpendicular to the first surface. The vertical dopant profile of at least one of the first and second columns includes first portions separated by second portions. In each of the first portions a dopant concentration varies by at most 30% of a maximum value within the respective first portion.

Abstract: A manufacturing method provides a semiconductor device with a substrate layer and an epitaxial layer adjoining the substrate layer. The epitaxial layer includes first columns and second columns of different conductivity types. The first and second columns extend along a main crystal direction along which channeling of implanted ions occurs from a first surface into the epitaxial layer. A vertical dopant profile of one of the first and second columns includes first portions separated by second portions. In the first portions a dopant concentration varies by at most 30%. In the second portions the dopant concentration is lower than in the first portions. The ratio of a total length of the first portions to the total length of the first and second portions is at least 50%. The uniform dopant profiles improve device characteristics.

Abstract: A medical imaging system has a modality for acquiring images, components for processing the images, a communication linkage for the transmission of the images and memory arrangement for storing the images with a number of separate memory systems. The memory arrangement includes a control system which causes successive image datasets to be stored in separate memory systems.

Abstract: A pumpable baking additive for improving the quality of backed goods with a viscosity of at least approximately 500 mPas−1 and a water activity (aw) of approximately ≦0.94 is physically and microbiologically stable for several weeks without cooling.

Abstract: A sorting installation for useful products is proposed, which serves in particular to sort out reusable packaging materials. In order to achieve the sorting-out of individual types of packaging with maximum efficiency, the sorting-out of individual monofractions is undertaken, on one or more manual sorting sections, onto a collector conveyor belt which is connected in parallel, the content of which, after sorting-out is complete, is introduced into an associated bunker.

Abstract: A method is proposed for recovering valuable substances, particularly from construction site wastes and industrial trash as well as a system for implementing the method in which the essential sorters are disposed in a closed container which can be placed onto an elevated foundation. The foundation is formed by intersecting walls which simultaneously serve as partitions for various bunkers.

Abstract: A roller for the pressure treatment of webs, especially a roller such as a press or calender roller for the treatment of paper, cardboard and pulp webs in machines of the paper industry, which include a roller shell, roller flange and a roller shaft, one or more elastic, axial or coaxial clamps and elastic or yielding centering structures. The roller shell includes individual rings of sintered ceramic disposed side by side, the rings are clamped positively together by the one or more elastic, axial or coaxial clamps and the rings are aligned concentrically on the roller shaft by means of the elastic or yielding centering structures.

Abstract: A process is described for direct determination of complex corrosive environmental conditions, which comprises exposing a glass surface to the environment and examing the glass surface before and after exposure using a measurement method based on radiation, in particular a IR-spectroscopic method, in order to determine corrosion effects, in particular water absorption and ion exchange. Glass sensors suitable for use in this process are likewise described.

Abstract: A sorting machine which serves for treatment of mixtures of refuse, especially household rubbish, trade waste, industrial waste, refuse from demolition, waste from building sites, and also waste from wood or the like.

All the package parts are produced from glass, are connected to one another by using solder glass as a sealing material. The parts are dilathermally matched with one another.

Abstract: A radially-sealing ring has a sealing element of a non-elastomeric plastic, preferably of PTFE, planar, annular disk having plane-parallel surfaces held at its outer circumference in a stiffening ring and cold flexed in the axial direction to form a cuff at its inner circumference which engages the shaft with bias. The disk has a thickness of from 0.3 to 0.8 mm and an inside diameter approximately 1.5 to 7 times its thickness less than the diameter of the shaft. The distance between the shaft and the line about stiffening ring where the disk is held is 2 to 7 times as great as the thickness of the disk. The radially-sealing ring is preferably for sealing the crankshaft of a two-cycle engine.
