摘要:
A planetary cooler has a plurality of circumferentially spaced cooling tube supports each of whichhas a pair of axially spaced side plates and an insert with two flanges which are fitted into openings in the side plates and welded to the latter. Each flange has a pyriform opening which communicates with a radial clearance extending between circumferentially adjacent side plates at their radially outer portions.

A rotary kiln having a row of planetary cooler tubes disposed around its outer periphery and carried by individual metal mountings on the kiln casing, adjacent mountings abutting against each other in their areas bordering on the kiln casing and being spaced apart in their areas remote from the kiln casing, for minimizing changing temperature induced stresses imparted therefrom to the kiln casing during operation.
摘要:
A semiconductor body includes a substrate, a buried zone having a first conductivity type that is formed in the substrate, a first zone having the first conductivity type that is above the buried zone, a second zone having a second conductivity type that is different from the first conductivity type and above the first zone, and a third zone having the first conductivity type that is above the second zone. The buried zone includes first and second implantation regions that are formed via first and second implantations that are performed using a mask. The buried zone, the first zone, the second zone and the third zone are parts of a first transistor structure.
摘要:
A method for manufacturing a semiconductor body with a trench comprises the steps of etching the trench (11) in the semiconductor body (10) and forming a silicon oxide layer (12) on at least one side wall (14) of the trench (11) and on the bottom (15) of the trench (11) by means of thermal oxidation. Furthermore, the silicon oxide layer (12) on the bottom (15) of the trench (11) is removed and the trench (11) is filled with polysilicon that forms a polysilicon body (13).
摘要:
A light-sensitive component which has a semiconductor junction between a thin relatively highly doped epitaxial layer and a relatively lightly doped semiconductor substrate. Outside a light incidence window, an insulating layer is arranged between epitaxial layer and semiconductor substrate. In this case, the thickness of the epitaxial layer is less than 50 nm, with the result that a large proportion of the light quanta incident in the light incidence window can be absorbed in the lightly doped semiconductor substrate.
摘要:
This invention relates to a rotary kiln for the heat treatment of material and having a number of elongate satellite cooling tubes distributed uniformly around the rotary kiln periphery at the exit end of the kiln, the inlet ends of these tubes being connected by short inlet pipes to the interior of the rotary kiln, and each tube being supported on the rotary kiln casing by two support bearings which accommodate axial movement of the tubes relative to the kiln occasioned by thermal expansion or contraction of the tubes. Mounting of the bearing means accommodates a close spacing between adjacent tubes.
