20110059839 | TRANSLUCENT POLYCRYSTALLINE SINTERED BODY, METHOD FOR PRODUCING THE SAME, AND ARC TUBE FOR HIGH-INTENSITY DISCHARGE LAMP - A translucent polycrystalline sintered body is mainly composed of an alumina, is suitable for the manufacture of an arc tube for a high-intensity discharge lamp, and has an average grain diameter of 35 to 70 μm, preferably 50 to 60 μm. In a case where the sintered body is in a 0.5-mm-thick flat plate shape, the in-line transmittance of the sintered body is 30% or more, preferably 50% or more. In this case, the ratio between maximum and minimum in-line transmittance values is 2:1 to 1:1 in the visible region of 360 to 830 nm. The bending strength of the sintered body is 250 MPa or more, preferably 300 MPa or more. | 03-10-2011 |
20110114352 | CERAMIC TUBE FOR HIGH-INTENSITY DISCHARGE LAMP AND METHOD OF PRODUCING THE SAME - The present invention relates to a ceramic tube for a high-intensity discharge lamp, comprising a hollow member and a plug member. The hollow member contains a substantially cylindrical body and a closure for closing one end of the body, and the plug member is inserted into an insertion opening formed at the other end of the body. Before the insertion of the plug member, the insertion opening has a tapered portion with a diameter decreasing in the direction from the open end to the inside at least in an area into which the plug member is inserted. After the insertion of the plug member, an outer wall of the plug member is bonded to an inner wall of the insertion opening. | 05-19-2011 |
20120133279 | ARC TUBE AND METHOD OF MANUFACTURING SAME - An arc tube includes a light emitting body for light therein and a ceramic tube having a first capillary and a second capillary integral with respective opposite sides of the light emitting body. A first electrode is inserted and sealed in the first capillary, and a second electrode is inserted and sealed in the second capillary. The first electrode is sealed in the first capillary by shrink fitting. | 05-31-2012 |
