Filed: 1994-12-27
Abstract: PURPOSE: To prevent the generation of the crack or swelling of a friction mate rial to improve a yield by heat-treating the friction material surface by radiation heat due to a red-heated sheet-like heater. CONSTITUTION: A first sheet-like burner 3 and a second sheet-like burner 4 of a rectangular shape matched with the shape of a friction material are juxtaposed at an interval of given distance at a given height from the friction material surface at the given position of a conveyer belt 2 for carrying the friction material 1 to be heat-treated by an intermittent feeding action. In these sheet- like burners 3 and 4, since a combustion gas is burnt through many small holes, a lower end combustion surface is red-heated to become a radiation heat source. The friction material 1 is carried by the conveyer belt 2 under the red-heated sheet-like burners 3 and 4, at first, is stopped for a fixed time under the first sheet-like burner 3 to be pre-heated, and then is moved to under the second sheet-like burner 4 to be full-burnt.  The generation of the defectiveness such as a crack or swelling due to a sudden thermal shock can be eliminated, and all the surface can be uniformly burnt by thus heat-treating the surface of the friction material 1 by using radiation heat.

IPC: H01J61/52
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To efficiently transfer locally stored heat in the vicinity of the center hole along which an anode is formed to a block-shaped second power supply member with a plate-shaped heat transfer member by interposing the plate-shaped heat transfer member having higher heat conductivity than the second power supply member between a lamp main body base end part and the second power supply member for supporting the anode. SOLUTION: By lighting a lamp, temperature of an anode 22 is raised, and since a lamp main body 1 is made of alumina having low heat conductivity, the vicinity of the center hole 11 of the lamp main body 1 near to the anode 22 becomes higher temperature than other part. Since a heat transfer member 9 having high heat conductivity is bonded to the base end part 1b of the lamp main body 1, heat in the vicinity of the center hole 11 is transferred from the central part of the heat transfer member 9 made of a high heat conductive metal to the diameter direction, furthermore transferred to a block-shaped second power supply member 3 of the base end part of the lamp main body 1, temperature gradient in the diameter direction of the second power supply member 3 is decreased, heat is wholly transferred,  and heat is efficiently radiated from the edge of the second power supply member 3 to prevent heat storage in the vicinity of the center hole 11. Deterioration or color change caused by chemical change of a metal deposit film on a reflecting surface 1a is prevented, and drop in reflectance can be prevented.
