Description

Spannungs- oder Spannungsvergleichsanzeigeröhre Es sind Spannungs- und Spannungsvergleichsanzeigeröhren bekannt, welche insbesondere zur Ausgleichung von Symmetriefehlern mit einem justiermagneten ausgestattet sind. Diese justiermagneten können sowohl innerhalb als auch außerhalb des Entladungsgefäßes angeordnet sein.Voltage or voltage comparison indicator tube There are voltage and voltage comparison indicator tubes known, which are used in particular for compensation of symmetry errors are equipped with an adjustment magnet. These adjusting magnets can be arranged both inside and outside the discharge vessel.

Die vorliegende Erfindung sieht nun eine vorteilhaftere Ausführung darin, daß geeignete Bauteile des Systems nach Fertigstellung der Röhre so magnetisiert werden, daß die Symmetrie der Röhre erreicht wird. Die Ausführung erfolgt derart, daß geeignete Bauteile der Röhre, beispielsweise Steg, Winkelkasten, Blende, Abschirmring, Abdeckkappe, Gitterstrebe oder irgendein sonst geeignetes Bauteil des Systemaufbaues, aus magnetischem Material hergestellt wird und dann, nachdem die Röhre fertiggestellt ist, bei Vorhandensein eines Symmetriefehlers ein magnetisches Feld derart angelegt wird, daß der Symmetriefehler aufgehoben wird. Dabei ist es vorteilhaft, dasjenige Bauteil, das später zum Magneten werden soll, möglichst klein zu halten; ferner kann es vorteilhaft sein, den später zum Magneten werdenden- Bauteil- aus Baustoffen mit großer Koerzitv kraft herzustellen. Ferner ist es zweckmäßig, die räumliche Anordnung des Bauteiles so zu wählen, daß sein im. Vakuum verlaufender magnetischer Fluß auch von -möglichst vielen Elektrobahnen geschnitten wird. Die kleine geometrischeAbmessung und die größere Koerzitivkraft werden verhindern, daß magnetische Fremdfelder, wie beispielsweise Lautsprecherfeld, einen dauernden Magnetismus hinterlassen. Dag nachträgliche Magnetisieren irgendeines Röhrenbauteiles aus magnetischem Material hat noch den weiteren Vorteil, daß - sollte beim Magnetisieren die Symmetrielage infolge zu starken Magnetfeldes überschritten sein - man durch ein entgegengesetztes magnetisches Feld -diesen Fehler leicht wieder beheben kann. Damit beim Anlegen des magnetischen Feldes nur der vorgesehene Bauteil permanent magnetisch wird, kann es vorteilhaft sein, die-anderer- Systembauteile aus unmagnetischem Material herzustellen.The present invention now sees a more advantageous embodiment in that suitable components of the system are so magnetized after completion of the tube that the symmetry of the tube is achieved. The execution takes place in such a way, that suitable components of the tube, e.g. bridge, angle box, cover, shielding ring, Cover cap, lattice strut or any other suitable component of the system structure, made of magnetic material and then after the tube is completed is, in the presence of a symmetry error, a magnetic field is applied in this way is that the symmetry error is canceled. In doing so, it is beneficial to the one Keeping the component that will later become a magnet as small as possible; further it can be beneficial to the component that will later become a magnet from building materials with great coercive force. It is also useful to choose the spatial arrangement of the component so that its in. Vacuum running magnetic flux is also cut by as many electric railways as possible. the small geometric dimension and the larger coercive force will prevent External magnetic fields, such as loudspeaker fields, permanent magnetism leave behind. Dag subsequent magnetization of any magnetic tube component Material has the further advantage that - should the symmetry position when magnetizing be exceeded as a result of too strong a magnetic field - one by an opposite magnetic field - this error can easily be remedied. So when you put on of the magnetic field only the intended component becomes permanently magnetic it can be advantageous to manufacture the-other- system components from non-magnetic material.
