Abstract | PURPOSE:To allow mass production by dividing the high-pressure substitution cleaning process of the absorbed impure gas with the high-purity gas and the gas seal processing process guiding, cooling and condensing the sealed gas then chipping off an exhaust pipe. CONSTITUTION:In the substituting and cleaning process A with the high-pressure gas, the exhaust pipe 3 of a seal lamp PL is inserted into the fitting port rubber head 10 of a manifold. The lamp PL is then exhausted. The high-purity cleaning gas is guided into the lamp PL with high pressure. The lamp PL is kept heated at a high temperature during this time. This high-pressure cleaning is repeated several times. When the cleaned lamp PL is moved to the next process B, a bulb is prevented from being kept at the atmospheric pressure or below. The lamp PL is inserted into the lamp insertion head 20 of a machine. It is then rough-machined, blind-machined, leak-checked and exhausted. Gas is sealed. The gas-sealed lamp PL is moved to a liquid nitrogen-cooled head, the sealed gas is liquefied and condensed. The lamp PL is then chipped off at the preset narrow section. |
