Monitoring of low currents through a low-side driven DMOS by modulating its internal resistance

摘要

The tensioning apparatus is destined for use with silk screens essentially constituted by a flat frame (10) on which a screen material (2) or sieve is arranged. It comprises means for fixing the screen material (2) peripherally on the frame (10), and means for tensioning, associated to the frame (10), which operate between the frame (10) and the screen material (2) in order to tension the screen material (2). <IMAGE>
