Abstract

PURPOSE:To remove the swelling of the sealing part by performing sealing using the pressure inside of a pressure vacuum box while further leading gas into the box simultaneously with finished sealing while raising the pressure inside of the box higher than the pressure inside of a bulb. CONSTITUTION:An outer cylindrical bulb having a head formed in the round or lens shape is mounted on a bulb holding jig 11 furnished with a large number of holes while setting a sealing bead 4 fitted up with a filament 2 inside of the opening part of an outer cylindrical bulb 1 and arranging outside a carbon jig 9 for heating. While housing this inside of a pressure vacuum box 6 and vacuumizing the inside of the box, the carbon jig 9 is electrically heated in order to promote generation of gas while closing the vacuum bulb 17 when the vacuum degree is raised followed by leading-in sealing gas in order to obtain the prescribed gas pressure. Next, a flow of current in the carbon jig 9 is intensified so as to raise temperature in order to seal. After being sealed, a small quantity of gas is led in to raise the gas pressure inside of the vacuum box 6 a little higher than the gas pressure inside of the bulb 1, then the current flow is stopped to finish heating.

造方法。Detailed Description of the Invention: An outer cylindrical bulb with a circular or lens-shaped head is mounted on a bulb holding jig with a large number of holes, and the filament is then attached to the bulb holding jig. 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. Arrange a jig to determine this, place it in a pressurized vacuum box, evacuate the pressurized vacuum box, and then heat the carbon jig with electricity to remove the air from the pressurized vacuum box and the equipment jig, etc. Gas generation is promoted, and when the atmosphere inside the box reaches the same conditions and the degree of vacuum increases, the vacuum valve is closed, and the sealed gas is introduced to achieve the specified gas pressure. Next, the power to the carbon jig is increased to raise the temperature and increase the gas pressure a little. A method for producing small gas-filled lamps in which the electricity is then turned off and heating is terminated to produce multiple products at once.

特徴とする、小型ガス入りランプの製造方法By using a pressurized vacuum box, it is possible to set an arbitrary gas field force inside the valve that is unrelated to atmospheric pressure, and the expansion field force of the gas inside the valve due to the heat of sealing the valve and beads and the increase in the pressure inside the applied vacuum box can be set. Taking advantage of this fact, we performed layer-resistant processing, and at the same time as heating and cuff sealing were completed, we further raised the gas groove in the pressurized vacuum box to eliminate the bulge in the sealed part.
