Cathode device for cathode-ray tube |
摘要 |
In a cathode-ray tube provided with a direct-heating type cathode, a transformer through which the cathode is heated is disposed within the bulb of the cathode-ray tube. This improvement eliminates the instability of heating due to the contact resistance caused between the base pins of the cathode-ray tube to which the terminals of the cathode are connected and the socket pins to which the base pins are fitted.
