摘要:
A cathode ray tube device has a neck, a funnel, a face panel, an inner conductive film disposed on an inner surface of the funnel, a first outer conductive film disposed on an outer surface of the funnel, and a deflection yoke. The inner conductive film and the first outer conductive film act as a capacitor. A second outer conductive film for electric field shielding is disposed on an outer surface of the funnel. The second conductive film is disposed between the deflection yoke and the first outer conductive film in such a way that the second outer conductive film is separated from the deflection yoke and is not covered by the deflection yoke.

A cathode ray tube comprising a vacuum enclosure including a glass panel 1 whose inner face is coated with a phosphor film 4 to form a screen; a neck portion housing an electron gun; and a funnel portion connecting the glass panel and the neck portion. A multi-layered anti-reflection, anti-electrostatic charge film formed on the outer face of the glass panel is constructed of a high refractive index film having a refractive index of 1.6 to 2.2 and a low refractive index film having a refractive index of 1.3 to 1.58. The high refractive index film is sandwiched between the outer face of the glass panel and the low refractive index film, and an unevenness having an average diameter of 5 to 80 .mu.m is provided at the interface between the high refractive index film and the low refractive index film. The interface has a height of 10 to 40 nm. The unevenness of the surface of the low refractive index film is made smaller than the average roughness Rz of the unevenness of the interface between the high refractive index film and the low refractive index film, or the surface of the low refractive index film is flat.

A heat-shrink band for a cathode ray tube (CRT) has a light weight, corrects the deformation of an object, such as a panel of a CRT due to the air pressure, effectively prevents implosion of the CRT, can suppress the color deviation, and in addition is excellent in formability. The method of fabricating the heat-shrink band includes a composition of cold rolled steel sheet such that the heat-shrink band offers both a high elongation characteristic at an ambient temperature and a high stress of yielding point characteristic after the heat-shrink process. The reduction of the weight of the heat-shrink band contributes to an overall reduction of the weight of the CRT.

A second film that contains a substance that secures the conductivity of conductive particles is formed on a first film that contains the conductive particles. The first film and the second film are sintered at the same time. Thus, a conductive anti-reflection film having a sufficiently low surface resistance with a sufficient transmissivity for a high transparency can be obtained with high cost performance. When the conductive anti-reflection film is used for a cathode ray tube, it can almost prevent the AEF (Alternating Electric Field), display a picture in high quality, and be excellent in cost performance.

A method of forming a fluorescent screen, such as a black matrix or a color filter, on a front panel of a cathode ray tube is described. The method comprises the steps of forming a photosensitive adhesion layer on an inner surface of the front panel, exposing the photosensitive adhesion layer through a color selecting electrode having a plurality of slots for reducing adhesion level of exposed area of the photosensitive adhesion layer, bringing a pigment layer provided on a supporting sheet into intimate contact with the photosensitive adhesion layer, applying pressure to the pigment layer and the photosensitive layer, and peeling off the supporting sheet from the pigment layer. Alternatively, a pigment may be dispersed in the photosensitive adhesion pigment layer. In the case, the photosensitive adhesion pigment layer is brought into intimate contact with the inner face of the front panel and exposed through a color selecting electrode, followed by the steps of applying pressure and peeling off a supporting sheet from the photosensitive adhesion pigment layer.

A color cathode ray tube includes a faceplate and a phosphor screen provided on the inner surface of the faceplate and including red, green, and blue phosphor layers. A color filter layer is interposed between the inner surface of the faceplate and the phosphor screen. The color filter layer includes color filters opposed individually to the phosphor layers of the phosphor screen and having colors corresponding thereto. Color filters of each color have a higher transmittance for light beams with wavelengths which are in a range of .+-.20 nm of the maximum emission spectrum wavelength of the phosphor layers of the corresponding color than for light beams with wavelengths which are outside the range and which are between 400 nm and 650 nm. A common outside filter for complementing the light absorption properties of the color filters is provided on the outer surface of the faceplate and has a maximum absorption in a predetermined wavelength which is outside the maximum emission spectrum wavelengths of the red, green, and blue phosphor layers.

An electron beam emitted from an electron gun enters into an accelerator 8 through a magnetic lens and is accelerated by a large number of accelerating tube discs within the accelerator, resonance cavities formed thereby and a magnetic field supplied from the outside. Then, it is focused by a focusing magnet and enters into an energy analyzer and scanned by a beam scanner, and is irradiated as a beam onto a sterilization goods item. On the outside of the accelerator there is disposed a cooling jacket for making uniform the thermal expansions of the resonance cavities due to thermal load. Also, by providing frequency adjusting means for adjusting the frequency of an accelerating microwave input through an input coupler and also by the cooling jacket having its thickness gradually increased from the inlet toward the outlet so as to make the thermal expansions of the resonance cavities zero, it becomes possible to make the amount of variation in the acceleration phase zero to thereby enable provision of an accelerator apparatus with large output and high energy density. Furthermore, in the energy analyzer, a particle energy necessary for sterilization is selected by bending magnet energy means and slit and irradiated, with the result that an effective electronic sterilizer apparatus can be realized.
