Patent DE-19707691-A1 (DE)
Title: Pull tension distribution measurement method for in metal band
Inventor: BERGHS ANDRE DIPL ING
IPC: G01L5/04
Filed: 1997-02-26
Abstract: The method involves measuring a pull tension distribution over the entire width of a metal band between two milling arrangements or between a milling arrangement and a reel or a roll. A force is exerted on the metal band by an electromagnetic field, which causes a movement of the metal band. The movement of the metal band is measured and is used for the calculation of the pull tension distribution over the width of the metal band. An alternating electromagnetic field, especially with a frequency between 1 to 200 Hz, is preferably used, to produce a periodic force which causes a periodic movement, i.e. a bent wave, especially in a longitudinal direction of the metal band.

Filed: 1997-12-06
Abstract: A silicon-germanium hetero bipolar transistor comprising a silicon collector layer, a boron-doped silicon-germanium base layer, a silicon emitter layer and an emitter contact area. The transistor is fabricated using an epitaxy process on a surface of pure silicon. An electrically inert material is incorporated into the epitaxial layers in order to link the defects in the semiconductor structure and to reduce the outdiffusion of the dopant. Thus, a transistor for high-frequency applications can be fabricated in two ways: to increase the dopant dose of the base region or to reduce the thickness of the base layer. In particular, the concentration profile of germanium in the base layer has a general shape of a triangle or trapezoid.
