Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method which can improve mass productivity of an impregnated cathode for an electron tube. SOLUTION: A porous tungsten disk 10 composed of a porous metal substrate is impregnated with an electron emitting material 11 (e.g. Ba) at 1650 deg.C for instance, and washed in a washing process 30. Subsequently, an Ir film is formed on the surface of the porous tungsten disk 10. After that, the obtained cathode is subjected to a vacuum heat treatment, for instance, for 5 minutes at 1650 deg.C in a vacuum heat treatment process 40, so that the cathode is activated. Subsequently, a cap 50 and a sleeve 60 are brazed to obtain a completed inner sleeve 80.

Abstract: PURPOSE: To provide a manufacturing method of an impregnated cathode which effectively suppresses a variation of a cut-off voltage with the elapse of time and grid emission and further excels in mass productivity. CONSTITUTION: In a process after impregnating a base metal with an electron emitting substance and further before incorporating it into a cathode-ray tube, excessive Ba in the electron emitting substance contained in the base metal is eliminated. An excessive substance eliminating process is conducted within a range of 1600-2000 deg.C and heating time 0.1-60 minutes, particularly the about 1800 deg.C and heating time of about 10 minutes being desirable. The heating is desirable to be conducted in a vacuum or non-oxidizing atmosphere. The excessive substance eliminating process is desirable to be conducted in a process before the base metal is fixed to a cap.

CONSTITUTION:An impregnated cathode 1 is formed of a porous base body 12 consisting of a high melting point metal and an electron emitting material impregnated in the porous base body, and platinum metal layers 14 are formed on the surface and reverse surface of the porous base body 12. An impregnated type cathode assembly is formed of a cup consisting of a high melting point metal, and the impregnated type cathode 10 housed in the cup, and the inner surface of the cup 20 is fused to the platinum metal layer 14 formed on one surface of the porous base body 12.

Abstract: PROBLEM TO BE SOLVED: To manufacture a cathode-ray tube having a long period of service and capable of maintaining good performance of electron emission. SOLUTION: A pyrolytic treatment process is provided in the evacuating process, in which the cathode is heated so that the water and vapor adsorbed in composite carbonates of the cathode are released. For example, a three min. heating is conducted at the temperature set to 550 deg.C. This is followed by a one and half minute heating at the first set temperature where pyrolysis of composite carbonates is generated, for example at 710 deg.C within the range 660-760 deg.C, and pyrolysis of the composite carbonates in the cathode is conducted. This is followed by a two min. heating at a second set temperature higher than the first where turning into solid solution takes place, for example at 980 deg.C within the range 930-1030 deg.C, which will actuate pyrolysis of the carbonate remaining undecomposed and turning of oxides into solid solution.

Abstract: PROBLEM TO BE SOLVED: To dissolve troubles in insulation caused by exposure of a core wire of a heater even after a wire rod for molding are melted and ejected. SOLUTION: This manufacture comprises a process (S1, S2) where a tungsten (W)/rhenium (Re) wire as a heater core wire for an electron tube negative electrode is wound around a Mo (molybdenum) wire as a molding wire rod, further the Mo wire wound with the W/Re wire is wound at a prescribed diameter to form a heater shape where the W/Re wire is doubly wound, a process (S3, S4) where alumina (a first insulation material) is attached on the periphery of the W/Re wire and the Mo wire formed into the heater shape by the winding, a process (S5) where the Mo wire attached with the alumina is chemically melted and ejected out of the alumina, and a process (S6, S7) where alumina (a second insulation material) is filled into a cavity formed by the melting and the discharge of the Mo wire.
