Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a cathode-ray tube and a manufacturing device therefor, capable of forming a high resistance film on the neck inner wall of a funnel at stable film thickness, and lessening a convergence drift due to the charge increase of neck potential. SOLUTION: A coating device for applying and forming a high resistance film on the inner wall 5a of the neck 5 of a funnel to form a cathode-ray tube had a nozzle 31 laid inside the neck 5. Also, the nozzle 31 has an injection hole 31a tilted down for injecting raw material fluid 41 toward the neck inner wall 5a. As a result of tilting the blow hole 31a downward, the volume of the liquid 41 flowing in a vertically upward direction after collision with the neck inner wall 5a is reduced. Consequently, a high resistance film of homogeneous thickness can be formed.

Abstract: PURPOSE:To make the focusing quality uniform by forming slits extened to the thickness direction of a dielectric substrate and facing to each other in rectangular direction and forming an electrode in both front and rear sides and the slits. CONSTITUTION:A resistor 33 and a capacitor 34 are installed respectively in a rear side of a pair of insulating supports 31 of an electron gun and in the other rear side. A terminal 36 in one end of the resistor 33 is connected with a shield cup C at the tip part and a terminal 37 in the other end is earthed through a variable resistor 40 and middle terminals 41, 42 are connected with middle electrodes Gm1, Gm2. Electron beams from a cathode are converged on a phosphor screen ultimately by main lens composed of an electrode G5, the electrodes Gm1, Gm2, and an electrode G6. Dynamic focusing voltage forms slits in the thickness direction from both front and rear sides of the dielectric substrates of the capacitor connected with electrodes to which voltage is not applied and to the direction rectangular to the thickness direction and an electrode is formed in the slits and thus electrostatic capacity is made large. As a result, a cathode-ray tube having uniform focusing quality is provided.
