Abstract: A method for manufacturing a cathode comprises the steps of: a process for applying onto a substrate a fluid mixture comprising polymers or precursors to the polymers, fine particles of electroconductive material or organic metal compound, and solvent; a process for removing the solvent by heating the fluid mixture applied on the substrate, thereby obtaining an electroconductive organic film comprising the polymers and the electroconductive material; and a process for forming a gap at a portion of the electroconductive organic film by applying an electrical current thereto. Accordingly, a simple method for manufacturing cathodes, electron sources, and image forming apparatuses with excellent electron emitting properties can be realized.

Abstract: A method for improving uniformity of emission current of a field emission display (100) includes the step of providing a first carbon nanotube (119) and a second carbon nanotube (118), which at least partially define an electron emitter (116). First carbon nantotube (119) is characterized by a first emission current capability and second carbon nanotube (118) is characterized by a second emission current capability, which is less than the first emission current capability. The method further includes the steps of causing first carbon nanotube (119) to be reduced in length at a first rate and, concurrently, causing second carbon nanotube (118) to be reduced in length at a second rate, which is less than the first rate and can be equal to zero, thereby reducing the difference between the second emission current capability and the first emission current capability and, thus, improving uniformity of emission current. The selective reductions in length are preferably achieved by performing the step of causing a burn-in current to be emitted by electron emitter (116).

Abstract: A method and apparatus for detecting position deviation of an electron gun in which, by increasing the light utilization efficiency to render the field of sight lighter and by reducing the amount of reflected light from the grid surface, the reflected light from the electron beam emitting surface is lighter to enable an edge of an electron beam transmitting hole to be discerned accurately to detect the position deviation of the electron gun accurately. The linear polarized light is illuminated on the electron gun and the light reflected by this electron gun is observed by a light polarization unit to detect the position deviation between grids of the electron gun.

Abstract: In a method of manufacturing an image display apparatus, a first member having an electron-emitting device and a second member having a phosphor which is irradiated with an electron emitted from the electron-emitting device to emit light are seal-bonded in a seal bonding chamber in which a vacuum atmosphere is realized. An aging step for the electron-emitting device is performed before the step of seal-bonding.

Abstract: An insulating diaphragm can be disposed on the saddle of getter flash turntable or other fixture used to support a cathode ray tube during frit knocking with a high voltage. The diaphragm protects the integrity of the cathode ray tube by preventing arcing of the high voltage through the neck of the cathode ray tube and into the supporting saddle.
