Description
Anordnung zur Zentrierung des Elektronenstrahls einer
Es ist bei Katodenstrahlröhren bekannt, zur Zentrierung des Elektronenstrahles auf dem Röhrenhals hintereinander mit geringem Abstand zwei axial magnetisierte Scheiben anzubringen, deren Magnetfeld durch gegenseitige Verdrehung der Scheiben verändert wird. Solche Scheiben haben zur Erleichterung der Produktion, insbesondere zur Vermeidung unnötiger werkzeugkosten meistens gleiche Beschaffenheit und sind daher mit einer gleichen Anzahl von Griffen ausgestattet. Hierdurch ergibt sich jedoch der Nachteil, daß bei bestimmten Stellungen der Scheiben die Griffe deckungsgleich übereinander liegen und somit nur schwer in eine neue Lage eingestellt werden können. Diesen Nachteil beseitigt die Erfindung.It is known in cathode ray tubes to center the electron beam two axially magnetized one behind the other at a small distance on the tube neck To attach discs, their magnetic field by mutual rotation of the discs is changed. Such discs have to facilitate production, in particular To avoid unnecessary tool costs, they are mostly of the same quality and are therefore equipped with an equal number of handles. This results in however, the disadvantage that in certain positions of the discs the handles are congruent lie on top of each other and are therefore difficult to adjust to a new position. The invention overcomes this disadvantage.
Die. Neuerung besteht darin, daß. die beiden Scheiben unterschiedliche Griffzahlen haben. Bei einem bevorzugten Ausführungsbeispiel der Neuerung hat die eine der beiden Scheiben 'zwei Griffe, während die andere Scheibe drei Griffe aufweist.The. The innovation is that. the two disks different Have grip numbers. In a preferred embodiment of the innovation one of the two disks has two handles, while the other disk has three handles.
Dadurch ergibt sich der Vorteil, daß in jedem Falle zwei Griffe so nebeneinander liegen, daß die beiden Scheiben in beiden Richtungen gegeneinander verdreht werden können.This has the advantage that there are two handles in each case lie next to each other so that the two disks face each other in both directions can be twisted.
Zur näheren Erläuterung der Neuerung wird im folgenden ein Ausführungsbeispiel anhand der Zeichnungen beschrieben. Dies zeigt in perspektiver Ansicht eine Katodenstrahlröhre 1 mit einer Ablenkspuleneinrichtung 2 und einer Zentriereinrichtung 3 aus zwei dicht hintereinander angeordneten axial magnetisierten Scheiben 4 und 5. Diese Scheiben können entweder aus magnetisierten Blechen oder aus gpreten Magneten, wie z.B.To explain the innovation in more detail, an exemplary embodiment is given below described with reference to the drawings. this shows in perspective view a cathode ray tube 1 with a deflection coil device 2 and a centering device 3 from two axially magnetized disks 4 and 4 arranged closely one behind the other 5. These disks can either be made from magnetized sheet metal or from solid magnets, such as.
Ferroxdure oder ähnlichem Material gefertigt sein. Die Scheibe 3 ist mit zwei Griffen 5 und 6 ausgestattet, während die Scheibe 4 drei Griffe 7,8 und 9 hat. Man sieht leicht, daß durch einen Druck auf die Griffe dir beiden Scheiben in dGr durch Pfeile 10 und 11 dargestellten Richtung die Scheiben leicht gegeneinander verdrehbar sind. Die Griffe können sowohl mit den Scheiben aus einem Stück gefertigt sein als auch mit ihnen zusammengefügt sein. In Fig. 2 und 3 sind die Scheiben 3 und 4 gesondert mit abgebogenen Griffen dargestellt. Eine solche Anordnung kann dann vorteilhaft sein, wenn die Scheiben innerhalb des Ablenkjoches drehbar befestigt sind.Ferroxdure or similar material. The disk 3 is equipped with two handles 5 and 6, while the disc 4 has three handles 7,8 and 9 has. You can easily see that by pressing the handles you can get both discs in the direction shown by arrows 10 and 11, the disks slightly against each other are rotatable. The handles can be made in one piece with the washers to be as well as to be joined with them. In Figs. 2 and 3, the disks are 3 and 4 shown separately with bent handles. Such an arrangement can be advantageous if the disks are rotatably mounted within the deflection yoke are.
