Abstract
A manufacturing method of cathode ray tube, wherein the voltage applied to the anode of an electron gun is divided by a voltage divider for application to focusing electrodes of the electron gun in the knocking process.
Claims6
A manufacturing method for a cathode ray tube comprising the steps of dividing a voltage applied to an anode of an electron gun by voltage dividing means formed of at least two resistances for application to lower electrodes of the electron gun in a knocking process, and connecting one capacitor in parallel to the at least one of said at least two resistances forming said voltage dividing means.
A manufacturing method for a cathode ray tube comprising the steps of dividing a voltage applied to an anode of an electron gun by voltage dividing means formed of at least two resistances for application to lower electrodes of the electron gun in a knocking process, and providing an inductance in series between said voltage dividing means and a knocking power supply.
A manufacturing method for a cathode ray tube comprising the steps of dividing a voltage applied to an anode of an electron gun by voltage dividing means formed of at least two resistances for application to lower electrodes of the electron gun in a knocking process, and providing a spark gap in parallel to at least one of said at least two resistances forming said voltage dividing means.
