The joint assembly has a seal that extends between a first flange of a first section and a second flange of a second section. The seal sealing a gap defined between the first and second flanges. | 09-23-2010 |
20110177747 | Method of Making a Fritless Seal in a Ceramic Arc Tube for a Discharge Lamp - A method of making a fritless seal in a ceramic arc tube body comprises the steps of: (a) inserting a feedthrough into an opening in a ceramic arc tube body, the feedthrough being comprised of niobium or a niobium alloy; (b) heating the arc tube body to a first temperature in an inert gas to at least partially sinter the arc tube body, the inert gas being selected from the group of argon, neon, krypton, xenon and mixtures thereof; and (c) further sintering the arc tube body by heating to a second temperature in a hydrogen atmosphere to form a hermetic seal between the feedthrough and the ceramic arc tube body, wherein the second temperature is higher than the first temperature. | 07-21-2011 |
20110237150 | MANUFACTURING METHOD OF HERMETIC CONTAINER - A manufacturing method of a high-reliability hermetic container includes an assembling step of arranging, between first and second glass substrates, a sealing material including first and second straight line portions stretching in different directions and a coupling portion connecting these straight line portions, with a viscosity of the sealing material having a negative temperature coefficient, and a scanning sealing step of performing scanning to the first straight line portion and the coupling portion while irradiating local heating light at least once. Scanning to the second straight line portion and the coupling portion is performed while irradiating the local heating light at least once, and the assembling step further forms at least a part of the sealing material at the coupling portion with a film thickness thinner than the sealing material in a region adjacent to the coupling portion of the first straight line portion. | 09-29-2011 |
20110294389 | LIGHT-EMITTING DEVICE, LIGHT EMITTING SYSTEM INCLUDING THE SAME, AND FABRICATING METHOD THEREOF - Provided are a light-emitting device having improved light dispersion efficiency, a light-emitting system including the same, and fabricating methods of the light-emitting device and the light-emitting system. The light-emitting device includes one or more light-emitting elements arranged on first surface of a substrate, an insulation film formed on the first surface of a substrate so as to cover the one or more light-emitting elements, and a plurality of uneven patterns formed on the insulation film formed on each of the one or more light-emitting elements so as to be spaced apart from each other, wherein the plurality of uneven patterns are all convex patterns or concave patterns and each of the plurality of uneven patterns has a curved cross-sectional shape. | 12-01-2011 |
20120021664 | METHOD FOR PRODUCING AIRTIGHT CONTAINER - A method for producing an airtight container includes preparing an assembly having a first substrate and a frame member, the first substrate having an electron-emitting element formed on a first surface thereof, the frame member mounted on the first surface outside an area where the electron-emitting element is formed; forming a temporary assembly having the assembly and a second substrate by bringing the second substrate into contact with the frame member via a joining member such that an inner space is formed; melting the joining member by irradiating the joining member with a laser beam transmitted through the second substrate; and solidifying the melted joining member. The laser beam is applied such that an incident direction at an irradiation position on the joining member does not include components toward the interior of the frame member while the laser beam moves relative to the temporary assembly. | 01-26-2012 |
20130052903 | PLASMA BULB SEALING WITHOUT A HYDROGEN FLAME - An electrodeless plasma lamp and method of forming a seal on an electrodeless bulb for use in the plasma lamp are described. The method may include providing a section of tube, cutting the tube to length, and sealing a first point on one end of the tube in a rounded fashion to form a first end of the electrodeless bulb. The cross-sectional diameter of an opposite end of the tube is reduced to form a tail on the electrodeless bulb. The tail is open to an interior portion of the bulb where the interior portion forms a cavity. One or more fill gases are injected into the cavity of the bulb. A first portion along the tail of the bulb is sealed thereby forming a truncated tail. A second point on the tail, intermediate between a terminal portion of the tail and a portion of the bulb containing the cavity, is sealed. The second point is sealed with a plasma torch by using an inert-gas element with a minimum of hydrogen gas. | 02-28-2013 |
20140073215 | REDUCED MASS END PLUGS FOR VOIDLESS CMH LAMPS - A voidless CMH lamp and a method of making such a lamp are provided. The CMH lamp includes a lamp body that receives at least one end plug. The end plug is constructed from a core of cermet material received within an outer layer of a ceramic material. An electrode is placed into the cermet material. The application of heat causes the cermet material to contract and eliminate voids between the lamp and cermet material. Co-sintering of the lamp, core, and outer layer provides a hermetic seal without necessarily using e.g., a sealing frit. Sintering of the ceramic material surrounding the cermet can be also used to improve light output and photometric performance of the lamp. The creation of one or more openings or recesses in the end plug can also provide performance improvements. | 03-13-2014 |
