CONSTITUTION:An air nozzle 4 and electron gun body are fixed so that the V- groove 20 of air nozzle 4 is located to the side surface of first grid 2 in the side of second grid 3 and thereafter a cathode 1 is located to the specified position using an air micrometer and is then welded to a cathode support 6. Thereby, as dispersin of interval between the first grid and the second grid, only the dispersion of plate thickness of second grid is considered and that of interval between the first grid 2 and the second grid 3 is eliminated. Thereby, accuracy of interval between the first grid 2 and cathode 1 can be improved drastically.,下面是Electron gun assembling method专利的具体信息内容。
