Abstract

Es wird eine einstellbare Spule für die Linearisierung der Zeilenablenkung von Bildschrimgeräten beschrieben, die einen Spulenkörper 1, eine Wicklung 8, einen von der Wicklung umgebenen sättigbaren Spulenkern 7 und einen Permanentmagneten 10 zur Vormagnetisierung des Spulen­ kerns 7 aufweist und deren Besonderheit darin besteht, daß zwischen dem Permanentmagneten 10 und dem Spulen­ körper 7 ein Luftspalt 11 eingestellt und hinsichtlich seiner Breite den jeweiligen Erfordernissen angepaßt werden kann. Die spezielle Konstruktion erlaubt auch eine kostengünstige Massenherstellung. It will be an adjustable coil for linearizing the Line deflection described by screen devices that a bobbin 1, a winding 8, one of the Surrounding saturable coil core 7 and a winding Permanent magnets 10 for biasing the coils Core 7 has and its peculiarity is that between the permanent magnet 10 and the coils body 7 set an air gap 11 and in terms of its Width can be adapted to the respective requirements. The special construction also allows an economical Mass production.
