Description of the invention (Technical Field) (Please read the notes on the back before filling this page) The present invention relates to an electron gun equipped with an impregnated cathode which is suitable as a color cathode ray Cathode ray tube of tube and manufacturing method thereof. In particular, it relates to a cathode ray tube which can prevent the deterioration of the radiation characteristics of an electron gun and prevent the heating part from being contaminated, and a manufacturing method thereof, without using an air cooling device when the glass members constituting the peripheral device are fused and sealed. [Background Art] The structure of the peripheral device of the conventional cathode ray tube includes: a display panel for projecting images; a tubular neck with an electron gun inside; a funnel-shaped funnel part for connecting the display panel and the tubular neck The stem is fused to the open end of the tubular neck; and the exhaust pipe is placed on the outer surface of the stem. —The display panel, the tubular neck, the leak, the bucket, the stem, and the exhaust pipe of the cathode ray tube's peripheral device are generally glass components. Usually, these glass members are sealed by fusing. In addition, the anode buttons, leads, and blue ends of other components are also fused. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The method of sealing by fusion is to use a gas-oxygen burner or tile; air-burner and other combustion devices to heat and soften the specified position of the glass member. , And a method of passing a current through a resistance wire such as a nickel-chromium or Kanth wire to heat a specified position of a glass member to soften it. In such a cathode ray tube, an electron beam emitted from an electron gun causes a phosphor provided on the inner surface of a display panel to emit light, thereby reflecting an image on a display panel. However, at this time, X-rays and rays are generated inside the cathode ray tube. This paper size applies to the national standard (CNS) A4 specification (210 X 297 mm) 460892 A7 B7 V. Description of the invention (>) When the X-ray leaks to the outside through the peripheral device, it will cause harm to the human body. Influence, so each glass member constituting the peripheral device should be made of glass with high X-ray absorption ability. Especially in the tubular neck, the average thickness is generally about 2.4 mm. When compared with the display panel or funnel, the thickness of the tube wall is thin, so it must have high X-ray absorption capacity. Therefore, the tubular neck is usually made of glass that has the highest X-ray absorption capacity of glass to contain P b 0 35% by weight, and the absorption coefficient for X-rays with a wavelength of 0.6A is 80 cm · 1 or more. The funnel part contains 0 ~ 30% by weight of PbO and is made of a glass having an absorption coefficient of X-ray of 0.6A and having an absorption coefficient of 40 cm · 1 or more. In addition, because the stem is sealed with metal, it is required to have high resistance and excellent thermal processing efficiency. In addition, the exhaust pipe is decompressed and exhausted at the same time as the cathode ray tube is baked and then sealed, so it is also required to have Excellent thermal processing efficiency. Therefore, the stem and the exhaust pipe are made of high lead-containing glass with excellent X-ray absorption capacity, electrical insulation, and thermal processing efficiency, respectively. However, the conventional cathode material for an electron gun mounted in a color cathode ray tube uses barium. However, in recent years, for the purpose of improving focus and improving image quality, electron guns of impregnated cathodes (hereinafter referred to simply as impregnated cathodes) using tungsten carbide as a cathode material have gradually spread. However, tungsten carbide is susceptible to oxidation at low temperatures when compared to barium. Therefore, when an electron gun impregnated with a cathode is exposed to a high temperature of 600 ° C or more, the cathode material is oxidized, so the radiation characteristics are liable to deteriorate. ^ 4 n This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) {Please read the precautions on the back before filling this page) ---- Order --------- line Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs-^ 1 ^ 1 ϋ-J IJ] n I-Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 6089 2 Α7 Β7 V. Description of the invention () The electron gun of the cathode is installed in the tubular neck. When the stem is fused to the tubular neck, in the conventional operation method, it is necessary to use an air cooling device to supply nitrogen to the electron gun to cool the cathode. In addition, when the exhaust pipe is sealed after the cathode ray tube is decompressed and exhausted, an air cooling device is required to suppress the temperature rise of the cathode of the electron gun. However, this type of air cooling device is extremely expensive, and it is very difficult to adjust the direction and amount of nitrogen supply, resulting in poor operation efficiency. In addition, in the heating method using a burner, due to impurities in the combustion gas and the like, there is a problem that a metal foreign matter adheres to the heating part and is easily stained. In the case where a foreign metal substance is adhered to the glass member, the resistance of the glass is reduced, so that insulation breakdown occurs and the resolution and illumination of the cathode ray tube are lowered, which is not good. In recent years, with the progress of large-scale cathode ray tubes, due to tensile distortion in glass, breakage, insulation damage, and reduction in resolution or illumination β are easy to occur. Therefore, the glass components constituting the peripheral device are more fused and sealed when they are fused and sealed. The prevention of pollution is strictly required. Therefore, an object of the present invention is to provide a cathode tube and a method for manufacturing the same, which can shorten the heating time and the heating temperature when the glass members constituting the peripheral device are fused and sealed, even if the electron gun with impregnated cathode is not used when the air cooling device is not used The characteristics are not deteriorated, and pollution of the heating portion can be prevented. [Disclosure of the invention] The present invention is a cathode ray tube, which constitutes the panel and the funnel part of the peripheral device.

Description of the invention (4) Neck, stem and The exhaust pipe is formed by a glass member, which is characterized in that at least one of the funnel part, the neck collar P, the stem, and the exhaust pipe is made of infrared absorbing glass, and the wavelength in the thickness direction is 1.05 nm. The infrared transmittance is 70% or less. In addition, the present invention is a method for manufacturing a cathode ray tube, which is used to heat and soften glass members in the panel's funnel, neck, stem, and exhaust pipe for fusion and sealing. At least one of the funnel portion, the neck, the stem, and the exhaust pipe. A glass member is formed by infrared absorbing glass, and the glass member is mainly used to soften it by heating it with infrared rays. As described above, the glass member is formed of infrared absorbing glass, and since the infrared transmittance of a wavelength of 105 nm in the thickness direction is 70% or less, the valley + easily absorbs heat rays. Therefore, when the glass member is fused and sealed, the heating time or heating temperature can be shortened. In addition, by using infrared light, laser, etc., it is possible to perform spot (s P 01) heating only on a specified portion of the glass member. In the case where any one of the tubular neck, the stem, and the exhaust pipe is formed of infrared absorbing glass in the manner described above, when it is fused and sealed, heat can be prevented from being transferred to the electron gun contained in the tubular neck. In addition, in the case where an electron gun having an impregnated cathode is mounted, it is not necessary to use an air cooling device to prevent oxidation of the cathode material. In particular, the fusion of the tubular neck and the stem can be performed effectively because it is performed near the electron gun. Both the tubular neck and the stem are preferably formed of infrared absorbing glass. In addition, the degree of pollution of the heating part when the burner is heating, with the heating -6- ____ This paper size applies to China National Standard (CNS) A4 specifications (2〗 0 X 297 cm) (Please read the note on the back first Matters are rewritten on this page) ---- Order --------- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 4 6089 89 ------ ^ --- V. Invention It means that (r) becomes longer, or the heating temperature becomes higher and larger. However, in the case where the glass member is formed of the infrared-absorbing glass as described above, since the time and temperature can be greatly shortened, the contamination of the heating portion can be prevented. The manufacturing method of the cathode ray tube of the present invention is that the main glass member is formed of infrared absorbing glass, and the glass member is mainly used to soften it by heating it with infrared rays, so that only a specified portion of the glass member can be spot-heated. For welding and sealing. That is, in the conventional heating method using a burner or a resistance of a burner, it may be difficult to perform spot heating only on a portion to be heated. That is, the surrounding portions that are not required to be heated are also heated, and the fixing jigs of the glass members and the ambient gas are also heated. Therefore, there is a waste of heat, and the heating rate or cooling rate is limited, and it is easy to cause a large amount of stretching and distortion in the glass member, which may cause damage. '' On the other hand, in the present invention, the glass member is mainly made of infrared rays. When it is softened by heating, there is no direct temperature rise in the unirradiated portion of infrared rays, and in addition, the infrared absorption rate is small. Glass does not have a direct temperature rise even when irradiated with infrared rays. Therefore, the glass member is formed by using a material with a high infrared absorption rate, so that infrared rays irradiated from an infrared lamp such as a halogen lamp or a xenon lamp are condensed and diffused through a lens or a mirror, and an appropriate density distribution can be performed only for the required ones. Partially irradiated. As a result, only a required portion can be heated and softened in a short time. The other 3 will not have the same size as the burner.

Description of the invention (b), glass components The method of the present invention in this way, because the glass members constituting the peripheral device are irradiated with infrared rays, and are fused and sealed by spot heating, they can be used to fused the display panel and the funnel part, the tubular neck and the funnel.

Therefore, when the Compared with welding and sealing methods, the heating operation time can be greatly shortened, and the heat can be reduced. In addition, when an electron gun with an impregnated cathode is used, the tubular neck and the stem are fused or sealed. When the gas tube is used, the oxidation of the cathode material can be prevented.

Description of the invention (7) Generally, the combination of the panel 10 and the funnel part 12 is performed by welding or glass frit sealing = the funnel part 12 and the neck part 11 The bonding is performed by melting. In addition, the anode button 15 is also fused (sealed) at the designated position of the funnel section 12. In addition, an electron gun 1 6 and an electron gun are installed in the neck 11 1. The lead! 7 forms a connection with the stem 1 3. The outer peripheral surface of the stem 1 3 is coated on the open end 3 of the neck 11 and one end of the exhaust pipe 14 is dissolved on the outer surface of the stem 13. In addition, the inner lead 17 is formed to be connected to the outer lead 18 enclosed in the stem 13. In addition, the other end of the exhaust pipe 14 is sealed after the cathode ray tube is baked while the exhaust is reduced in pressure. In addition, the figure also shows: the reinforcing band 20 is used to maintain the strength of the surface 10 and to prevent scattering when broken; the film 21 is used to prevent the fluorescent light from the phosphor '1 9 Return; cathode mask 22, which is used to specify the irradiation position of electron rays; studs 23, which are used to fix the shadow mask 22, and conductive film 24, which is used to conduct to the external ground to prevent electrons caused by the cathode mask 22 Rays are charged-high electricity. In general, a panel 10, a neck portion μ, a funnel portion 2 constituting a peripheral device of a cathode ray tube is a glass member.

Description of invention (#) Used to make the glass member melt, heating time during sealing and heating temperature can be reduced. In addition, because it is easy to absorb heat rays, it is possible to use a heating device such as an infrared lamp or a laser to perform spot heating only on a specified portion of the glass member. "In the above description, the tubular neck portion of the best form of the glass member Π, [Funnel part] 2, the stem 135 and the exhaust pipe 14 are all formed of infrared absorbing glass, but as long as at least one of these glass members is formed of infrared absorbing glass, sufficient effects can be exhibited. First, a case where the neck portion in the present invention is formed of an infrared absorbing glass will be described. When the neck is formed by infrared absorbing glass, the infrared transmittance at a wavelength of 1050 nm is preferably less than 60%, more preferably 50%, and most preferably 30% at a thickness of 2.4m. In addition, generally, when inserting the electron gun 16 into the neck 11, it is necessary to confirm that the electron gun 16 is disposed at the correct position for operation, so it is better to have a visible light transmittance of a certain degree or more. Therefore, the light transmittance of the neck 11 with respect to a wavelength of 57 nm in visible light, when converted to a thickness of 2.4 mm, is preferably 10% or less, and more preferably 20% or more. Therefore, the generally used neck Π has a flat thickness of about 2.4 mm, but the neck of the present invention is not limited to this ridge, and can be larger than it, for example, the average thickness is 3 mm, or it can be smaller than, for example, the average thickness is 2 mm Neck. In addition, if the neck fusion time is shortened or the fusion temperature is decreased, the viscosity of the glass can be reduced. However, in order to maintain other required characteristics, only the viscosity changes very much. -10- This paper size applies the Chinese national standard (CNS > A4 specification (210 X 297 mm)) --- --------- ^ * ! · 1 Order ---- III!

And when the viscosity of the neck glass is reduced If it is fused with the existing funnel or stem, it will cause a large stress, which may easily cause damage. (Please read the precautions on the back before filling this page) In order to reduce the infrared transmission of the glass used in the neck Content in glass is ~ 10% by weight (preferably 0.05 to 8% by weight, more preferably 0.1 to 7% by weight, and most preferably 1 to 7% by weight). In addition, it is used for Fe203 can be more effective when the ratio of reduced + is increased. Therefore, it is better to set the Fe2 + content to 0.03 wt% and the Fe2 + / Fe3 + ratio to 0.08 or more. In order to make Fe2 + in the glass, To increase, it is preferable to include a reducing agent such as metal Si. The content of the reducing agent is suitably 0.001 to 0.5% by weight. In the case of the original agent, the light transmittance in the visible light region of the neck can be maintained, and the light transmittance in the infrared region can be reduced. However, when the ratio of Fe2 + / Fe3 + is greater than 0.5, the reduction needs to be quite strong. As a result PbO in the glass is metalized into residues (stones), and the glass composition is easy to change, so it is not good.

In addition, the neck of the present invention is preferably made of PbO containing 20 ~ 40 The formation of infrared absorption glass by weight%. That is, when the PbO is 20% by weight or less, a sufficient X-ray absorption coefficient cannot be obtained as the neck glass. That is, in this case, for X-rays with a wavelength of 0.6 A The absorption coefficient cannot be more than 80cm · 1, because the amount of X-ray transmission becomes too large, which may cause adverse effects on the human body. On the contrary, when the amount of PbO is more than 40% by weight, the viscosity of glass It becomes too low, so it will be difficult to make the neck into a tube.

The reason why the content of SiOhAhOhMgC ^ CaC ^ SrC ^ BaC ^ NaaC ^ K ^ O, Sb203 and Fe203 in such a slope glass is limited is as follows. That is, SiO2 is a component that forms a network form of glass. However, when the content of Si02 is less than 38%, the viscosity of the glass becomes lower, which makes forming difficult. On the other hand, when the content of Si02 is more than 58%, the thermal expansion coefficient of the glass becomes too low, so it cannot be used. It matches the thermal expansion coefficient of the funnel glass. A1203 is also an ingredient that forms a network of glass.

In addition, in this case, a crystal called garnet is precipitated at the interface between the molten glass and the refractory, and the mechanical strength of the glass tends to decrease due to the crystal.

The glass used to form the stem or the exhaust pipe has an infrared transmittance to a wavelength of 1050 nm, which is 60% or less, preferably 50% or less when the thickness of the glass is 1.5 mm. In addition, in order to shorten the melting time and the melting temperature of the stem, and to shorten the sealing time and the sealing temperature of the exhaust pipe, the viscosity of the glass can be reduced. However, it is very difficult to maintain other required characteristics without changing only the viscosity. When the stem glass with only a change in viscosity is fused to an existing neck, a large stress is generated due to a difference in the viscosity curve when the glass is cured.

Therefore, it is better to make the content of Fe 2+ be more than 0.015% by weight, and to make the ratio of Fe 2 + / F e 3 + by weight. The ratio becomes 0.0 8 or more. In order to increase Fe2 + in the glass, it is preferable to include a reducing agent such as metal Sl. -16- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) {Please read the notes on the back before filling out this page > Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ^. * ^ 1 * 1 nn —1 order --------- line — /.

In addition, when a reducing agent is contained, the light transmittance in the visible light region of the funnel portion becomes 30% or more to maintain transparency and reduce the light transmittance in the infrared region. However, when the ratio of Fe2 + / Fe3 + is more than 0.5, it is necessary to make the reduction considerably stronger. As a result, PbO in the glass is metalized into a residue (calculus), and the glass composition is easily changed, so it is not good. In addition, the funnel portion of the present invention is preferably formed of infrared absorbing glass containing 10 to 30% by weight of PbO, that is, when the amount of PbO is less than 10% by weight, a sufficient X-ray absorption coefficient cannot be obtained as the glass of the funnel portion, that is, The absorption coefficient of X-rays with a wavelength of 0.6 A cannot be 40 cm · 1 or more. Therefore, the amount of X-ray transmission becomes too large, and therefore there is a problem that it has an adverse effect on the human body. On the contrary, when the amount of PbO is more than 30% by weight, it is difficult to form the funnel portion because the viscosity of the glass becomes too low. The funnel part of the present invention is preferably made of infrared absorbing glass, and the weight percentages of the components it has are SiO248 ~ 58%, Al2O30.5 ~ 6%, PbO10 ~ 30%, Mg 〇0 ~ 5%, C a 0 0 ~ 6%, S r Ο 0 ~ 9%,: B a 〇 0 ~ 9%, Na 2 0 3 ~ 9%, K 2 04 ~ 11%, 51) 2〇3 {) ~ 1% ^ 62〇30.2 ~ 10%.

Description of the invention (4) The reason why the content of K2O, Sb203, and Fe203 is limited is as follows. That is, S i02 is a component that forms a network form of glass. However, in the case of less than 0%, because of the glass The viscosity becomes lower, so forming becomes difficult. In the case of more than 58%, because the thermal expansion coefficient of glass becomes too low, it cannot match the thermal expansion coefficient of the neck glass. A1203 is also a network form of glass. However, in the case of less than 0.5%, the glass becomes difficult to form because the viscosity of the glass becomes low. In the case of more than 6%, the glass easily disappears and becomes transparent, the forming becomes difficult, and the coefficient of thermal expansion Becomes too low.

In addition, the infrared transmittance is formed by forming each sample into a plate shape, and after forming a specified thickness by optical honing (2.4mm ni stem for neck glass, 1.5mm for exhaust pipe glass, 1 Omni for funnel glass) , Using a visible and infrared spectrophotometer to measure the light transmittance at a wavelength of 1050nm. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In addition, the softening deformation time is to process each sample into a Pu wood rod with a size of 60 × 100 mm. , Hanging in an electric lamp, heating the central part 2cm in the length direction at a specified temperature to soften and deform the wood stick, and measure the time to elongate to 100 mm. The above specified temperatures are for neck, stem, glass for exhaust pipe is 75 ° C, and glass for funnel is 700 ° C. -27- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 4 B089 2 Α7 Β7 MM -------- V. Description of the invention (≫ In addition, the X-ray absorption coefficient is based on the glass composition and density, and the absorption coefficient is calculated for the wavelength of 0.6A. [Possibility of industrial use] As described above, the funnel portion of the cathode ray tube of the present invention At least one of the neck 3 stem and the exhaust pipe is easy to absorb heat rays. Because it is easy to soften and deform by heating, it can shorten the heating time and temperature when welding or sealing, and is suitable for using infrared lamps. Point heating with lasers, etc. Therefore, not only ordinary electron guns using barium as a cathode material, even when an electron gun with an impregnated cathode is installed, the radiation characteristics of the electron gun will not be deteriorated without using an air cooling device. Welding and sealing are performed. In addition, the manufacturing method of the cathode ray tube of the present invention is to make at least one of the funnel portion, the neck portion, the stem, and the exhaust pipe easily absorb heat rays. Infrared can be used to heat only the designated parts of the glass member for spot welding and sealing. Therefore, even when the electron gun with impregnated cathode is installed, the radiation characteristics of the electron gun will not be deteriorated even if the air cooling device is not used. Can be properly sealed and sealed. In addition, there is no conventional method of contaminating the heating part by the combustion heating of the burner. Therefore, the method according to the present invention is impregnated for use in which the radiation characteristics are easily deteriorated when exposed to high temperatures. The cathode of the electron gun is a color cathode ray tube, which can be properly fused with the β symbol on the neck and stem.
