Description of Invention (丨) [Detailed Description of Invention] [Technical Field to which the Invention belongs] The present invention relates to a glass-metal bonded electronic part. In other words, it relates to a glass-metal that can prevent cracks or cracks in the glass parts near the joint portion from occurring when the glass parts and metal parts are integrated by heating and firing, and the precision is improved. Bonded electronic parts. [Known technology] Electron guns for electronic tubes used in color imagers, etc., emit electrons corresponding to each of the three primary colors toward the fluorescent film coated on the panel portion of the colored Brown tube, which emits three primary colors of red, green, and blue. "Beam of Things" The electron beam is biased to scan by the influence of the electromagnetic field in a way that covers the entire screen, so that the image β is displayed. Although the electron gun with an electron tube is arranged in a line or in line on a plane at a certain interval, It is a △ type (triangle), but in any case, the three electron beams emitted from the electron gun for the tube must be adjusted to focus on one point on the fluorescent surface. Insufficient color will cause color difference in the picture. As an example of an electron gun for an electron tube, as shown in FIG. 3 (a), a longitudinal sectional view of an electron gun for an electron tube composed of a cathode, a G1 electrode (a first grid electrode), and a G2 electrode (a second grid electrode) is shown in FIG. In the electron gun 20 for an electron tube, the front surface of the cathode 21 thereof faces the G1 electrodes 22a having minute holes at a fine interval of 50 to 200 gm, and the G2 electrodes 22b are arranged at an interval of about 50450 / zm thereafter. The re-laminated G3-G6 electrodes become electron gun parts of composite parts. 3 Packing ----,-Ordering ------ line (please read the notes on the back of this page first) This paper size applies to China National Standard Half (CNS) A4 specification (210X297 mm) 434633 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. Description of Invention (>) When manufacturing the electron gun 20 for electronic tubes, first, glass 23, a cylindrical cathode support 5 made of metal and a cathode 21, and metal The cartridge 27 is manufactured by heating and firing. That is, a sheet of glass 23 formed by sheet forming through a row of holes for inserting three cathode supports 25 is housed in a metal box 27 provided with an opening on the bottom surface, and is fixed to Not shown in the fixture. Next, after inserting three cathode support members 25 into the holes, heating and firing are performed so that the glass 23, the cathode support member 25, and the metal box 27 are integrated. Next, a G1 electrode 22a is mounted on the cathode 21, and a G2 electrode 22b is laminated thereon, whereby an electron gun 20 for a tube is manufactured. However, the lamination operation of the cathode, G1 electrode, and G2 electrode by this method is entirely performed manually. Therefore, it not only takes time and accuracy, but also is a highly variable operation method. Therefore, the manufacturing method of the electron gun for an electron tube is to laminate the cathode, G1 electrode, and G2 electrode in advance, and then heat-fire and bond them to integrate the components (see Fig. 3 (b)). Generally, the structure of the electron gun 30 for the electron tube is that the skirt of the G2 electrode 22b of the conventional electron gun 20 shown in FIG. 3 (a) is unfolded and bent into a container shape, and the electrode and the cathode are housed in the container. . This type of electron gun 30 for an electron tube is heated and fired by heating the cathode 31, the G1 electrode 32a, the G2 electrode 32b, and the glass 33 so that the components are integrated. Here, one of the main obstacles to metal-glass bonding is due to the difference in thermal contraction (coefficient of thermal expansion) between metal and glass during the cooling process after firing. 4 t Please read the precautions on the back first (this page)

The glass used for bonding with metal generally uses a thermal expansion coefficient of 4.5 to 6.5x at 30 ~ 500 ° C: l (r6 / ° C, but considering the degree of such strain reduction, as a metal The components are Fe-Ni-based alloys close to the thermal expansion coefficient of glass.

Because it will be heated by electrons emitted from the cathode and become high temperature, it is generally used for cobalt alloys (Fe-29% Ni-17% Co) with low thermal expansion coefficient at high temperature. As for other metal components, Because it will not be heated to the high temperature as a cathode support, it is mainly used the cheap 42 alloy (Fe-42% Ni) »Because the electron gun parts are formed by overlapping G1 ~ G6 electrodes, in order to control the discharge from the cathode Acceleration, suppression, dispersion, and convergence of electrons 'The accuracy of the position of each part during assembly is strictly required. Although the G1 to G6 electrodes were assembled manually in the past, in order to improve workability, the parts with composite G1 and G2 electrodes were developed in order to improve workability.

Description of Invention (f) Although the problems that occur during assembly can be solved by compounding the electron gun parts, a new problem will occur, that is, cracks in the glass. Figure 3 is a conventional method of combining the G1 electrode and the G2 electrode. A cross-sectional view of a part. The inventors have investigated the cause of the cracking and found that if the G1 electrode and the G2 electrode are combined, the number of metal members bonded to the glass will increase, which is caused by firing. Due to the heat recovery of glass and metal during the subsequent cooling process Cracks may occur due to shrinkage, or thinning of the glass sandwiched between metal members. As a result, cracks may occur. In addition, composite parts are required to have high-precision dimensions. Specifically, For example, the gap between the holes through which the electrons of the G1 electrode and the G2 electrode pass must be assembled with a good accuracy within ± 5 / zm. Furthermore, when the parts are composited, the glass support on the cathode support also occurs when the glass is fired. Poor conditions such as glass on the edges. If glass is attached to the cathode support, when electrons are emitted from the cathode, the Ba ions of the cathode will adhere to the surrounding area and cause conduction, thereby impairing the insulation of the glass. In order to prevent the formation of cracks in glass, etc., after reviewing the results obtained by various methods, it was found that if a metal member is used, the thermal expansion coefficient of the metal between 30 and 500 ° C is higher than that of glass in the same temperature range. When the thermal expansion coefficient is in the range of 70 ~ 130%, good results will be obtained. That is, as shown in Table 1, the thermal expansion coefficient of a material exhibits a different 値 with each temperature, and the 値 may also have a reversal phenomenon between materials due to different temperature ranges. The inventors investigated the relationship between strain temperature, thermal expansion coefficient, and thermal expansion coefficient of metal when firing the glass. 'The results show that even in the case of such composite parts 6 ^ The paper size is applicable to Chinese national standards (CNS) Α4 mm) --------- ^ ------- '玎 ------ 0--(Please read the precautions on the back first ¾ this page) 4346 3 3 A7 B7 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs V. Description of the invention (y) When joining glass and metal, as described above, as long as the thermal expansion coefficient of the metal material between 30 ~ 500 ° C is glass The thermal expansion coefficient can be appropriately joined within a range of 70 to 130%. The object of the present invention is to provide a glass-to-metal bonded electronic part, which includes an electron gun for an electron tube and the like, and the glass member and the metal member are used in accordance with the optimum range that has been clarified.
