Description

Es sind Kathodenstrahlröhren für die Zwecke der Schwingungserzeugung und Verstärkung bekanntgeworden, in welchen mehrere als Anoden wirkende Auffangelektroden vorgesehen, sind sowie Ablenkplatten, bei denen die Wechselspannungen zugeführt werden und welche ein ähnlich wie in einer Braunsehen Röhre ablenkbares Kathodenstrahlenbündel abwechselnd auf die verschiedenen Anoden richten.They are cathode ray tubes for the purpose of vibration generation and amplification became known, in which several collecting electrodes acting as anodes are provided, as well as baffles, in which the alternating voltages are supplied and which is a cathode ray beam that can be deflected in a manner similar to that in a Braun tube Point alternately at the different anodes.

Gemäß vorliegender Erfindung werden zur Verbesserung der Wirkung und vor allem zur Vermeidung von störenden Rückwirkungen der Auffangelektroden und der daran angeschlossenen Kreise elektrostatische Abschirmungen vorgesehen, welche aus einer im Innern der Röhre zwischen den die Ablenkung steuernden Elektroden und den Auffan gelektroden angeordneten Schirmgitterelektrode und einem einen Teil des Vakuumgefäßes bildenden, auf dar Außenseite der Röhre eine Abschirmseiheibe unmittelbar tragenden Metallzylinder, der mit der Schirmgitterelektrode leitend verbunden ist, bestehen.According to the present invention, to improve the effect and most importantly to avoid disturbing repercussions of the collecting electrodes and those connected to them Circles of electrostatic shields are provided, which are made from inside the tube between which the deflection controlling electrodes and the collecting electrodes arranged screen grid electrode and one which forms part of the vacuum vessel and directly supports a shielding disk on the outside of the tube Metal cylinder, which is conductively connected to the screen grid electrode, exist.

Durch die Vereinigung dieser Maßnahmen wird jegliche sonst unter Umgehung des Schirmgitters mögliche Rückwirkung der Anoden auf die Steuerelektroden vermieden.By combining these measures, any otherwise bypassing the Screen grid avoided possible reaction of the anodes on the control electrodes.

Die Erfindung ist auf der Zeichnung in einer Abbildung dargestellt, welche eine erfindungsgemäß beschaffene Röhre in einer zur Schwingungserzeugung bestimmten Schaltung zeigt.The invention is shown in the drawing in a figure, which shows an inventive shows designed tube in a circuit intended to generate vibrations.

Die Kathode 1 der Kathodenstrahlröhre wird von der Stromquelle A geheizt, der von dieser emittierte Elektronenstrom 20 geht zwischen zwei langgestreckten, die Ablenkung steuernden Elektroden (13, 13') hindurch. Die Anoden 9, 9' sind durch eine Schirmelektrode 10, welche dem EntLadungsraum teilt, von der Kathode und von den Steuerelektroden elektrisch abgeschirmt. Die Elektrode 10 ist mit einem Metallzylinder 11, der auf der Außenseite einen Metallschirm 14 trägt, leitend verbunden und zweckmäßig auch an diesem befestigt. Die beiden in Gegentakt arbeitenden Anoden werden von einer Stromquelle B gespeist, deren positive Klemme mit dem Mittelpunkt des aus der Induktanz 20' und dem Drehkondensator 21 bestehenden Anodenkreises verbunden ist. Ein zweiter Metallzylinder 22, der die Steuerelektroden 13,The cathode 1 of the cathode ray tube is heated by the current source A , and the electron current 20 emitted by it passes between two elongated electrodes (13, 13 ') which control the deflection. The anodes 9, 9 'are electrically shielded from the cathode and from the control electrodes by a shield electrode 10 which divides the discharge space. The electrode 10 is conductively connected to a metal cylinder 11, which carries a metal screen 14 on the outside, and is expediently also attached to this. The two anodes working in push-pull are fed by a current source B , the positive terminal of which is connected to the center point of the anode circuit consisting of the inductance 20 ′ and the variable capacitor 21. A second metal cylinder 22, which the control electrodes 13,

iß' umgibt und den Kathodenstrahl konzentriert, wird über eine Leitung 18 von einer Stromquelle D negativ vorgespannt. Das Schirmgitter io erhält über eine Leitung 19 und den Schirm 14 von einer Stromquelle Zi positive Spannung1. Die Steuerelektroden 13' und 13 liegen an einer Induktanz 31, deren , Mittelpunkt über eine Leitung132 mit der negativen KLemme von C verbunden ist.Iß 'surrounds and concentrates the cathode ray is negatively biased by a current source D via a line 18. The screen grid io receives positive voltage 1 from a current source Zi via a line 19 and the screen 14. The control electrodes 13 'and 13 are connected to an inductance 31, the center of which is connected to the negative terminal of C via a line 1 32.

Die Stromquellen) D, C, E, B sind in Realie geschaltet und zwischen der positiven Klemme von C und der negativen Klemme von E geerdet. Zwecks Herstellung einer Rückkopplung ist die Spule 20' mit der Spule 31 gekoppelt. Diese induktive Kopplung bildet den einzigen Rückkopplungsweg, da wegen des Schirmgitters und des Schirmes 14 innerhalb der Röhre kerne Möglichkeit des Auftretens einer Rückkopplung besteht. Mit der Induktanz 20' kann eine Spule 40, die mit dem Belastungskreis verbunden ist, gekoppelt sein.The current sources) D, C, E, B are connected in real life and grounded between the positive terminal of C and the negative terminal of E. The coil 20 ′ is coupled to the coil 31 in order to produce a feedback. This inductive coupling is the only path of feedback since there is no possibility of feedback occurring because of the screen grid and screen 14 within the tube. A coil 40 connected to the load circuit may be coupled to the inductance 20 '.

Die Frequenz der erzeugten SchwingungenThe frequency of the generated vibrations

kann in an sich bekannter Weise durch einen Kristall 41, der im Nebenschluß zur Spule 31 angeordnet ist und außerdem durch eine lange Resonanzleitung 50, 51, die mit den beiden Enden der Spule 31 und den Klemmen des parallel geschalteten Kondensators verbunden und deren wirksame Länge durch einen Querleiter 52 veränderbar ist, stabilisiert werden.can in a manner known per se by a crystal 41 which is shunted to the coil 31 is arranged and also by a long resonance line 50, 51, which with the both ends of the coil 31 and the terminals of the capacitor connected in parallel connected and the effective length of which can be changed by a transverse conductor 52, be stabilized.
