Abstract

PURPOSE:To remove swelling of the sealing part by gradually heating to perform sealing process so as not to produce difference in the condition of gas expansion inside of a box due to heating temperature by using pressure inside of a pressure vacuum box. CONSTITUTION:An outer cylindrical bulb 1 having a round or lens-shaped head is mounted on a bulb holding jig 11 furnished with a large number of holes while setting a sealing bead fixed by a filament inside of the opening part of an outer cylindrical bulb 1 and arranging outside a heating carbon jig 5. While housing this inside of a pressure vacuum box 6 and vacuumizing the inside of the box, the carbon jig is electrically heated in order to promote gas generation while closing the vacuum bulb 16 when the vacuum degree is followed by leading-in sealing gas in order to obtain the prescribed gas pressure. Next, a flow of current in the carbon jig 5 is gradually intensified in order to seal with raised temperature while making not to produce difference between the gas pressure inside of the box and the gas pressure inside of the bulb and after finishing the sealing, the current flow is stopped to finish heating.

Place the attached sealing bead so that it is in contact with the inside of the opening of the external cylinder valve that has already been installed, place a heating carbon jig on the outside, and set the position of the bead on the top of it. A jig is placed to determine the stiffness, the stiffness is placed in a pressurized vacuum box, the inside of the pressurized vacuum box is evacuated, the carbon jig is heated with electricity, and the stiffness is removed from the pressurized vacuum box and equipment jigs. Promote gas generation, and when the atmosphere inside the box reaches the same conditions and the degree of vacuum increases, close the vacuum valve, -ile, and valve, and introduce the sealed gas to the specified gas pressure.Gas pressure inside the box and sealing valve The temperature is raised and sealed so that there is no difference in internal gas pressure. A method for manufacturing a small gas lamp, in which a large number of products are manufactured at once by turning off electricity and terminating heating immediately after sealing is completed.

Taking advantage of the fact that the expansion pressure of the gas inside the valve due to the sealing process heat and the increase in the pressure inside the pressurized vacuum box are the same, the layer-resistant processing temperature can be adjusted to the conditions under which the gas inside the box expands due to the heating temperature. A method for manufacturing a small gas lamp, characterized in that the electric current is stopped and the heating is terminated to eliminate the bulge in the sealing part.
