C〜350″C程度に昇温し来る様になる。In this example, the electrode structure shown in Fig. 3 can be placed in a container after the electrode assembly, and the temperature can be kept below about 200"C to 350"C, which prevents deviations in assembly accuracy and warping of parts. It is now possible to make the display as small and as small as possible, and a high-quality display can be obtained. In addition, when welding the front and back containers using a laser beam without using a metal plate, the surface of the welded area is extremely smooth and flat, and
After accurately positioning the welding area, the laser beam is adjusted with a lens system so that the minimum spot diameter is obtained before and after the welding area, and glass welding is performed directly. When welding is performed using metal plates, the welded part easily deforms, and there are no restrictions on the welding method or position.
Welding equipment such as gas welding, electric welding, ion beam welding, electron beam welding, light beam welding, etc. After the electrode assembly is installed in the back container and each electrode terminal is connected to the lead wire 6, the front container is placed and a metal plate is placed. A laser beam is applied to the periphery of parts 2 and 4, and welding is performed along the edges. This laser beam welding device may be a carbon dioxide laser device, a YAG laser device, or the like. After sealing by this bath welding, the exhaust device and the display device container are connected, evacuated, and heated to 200° in an electric furnace or the like.
The temperature will start to rise to around 350"C.
また、ビーム溶接にては、極めて小さくビームを絞る事
