Appeal No. 1998-2620 Application No. 08/512,033 Answer, page 5. Ozaki discloses the problem in CVD processes that a great amount of heat is dissipated from each of the opening ends and uniform heating at the setting temperature can only be obtained at a longitudinal central portion of the heating furnace (col. 1, ll. 55-59). Ozaki solves this problem by disposing a pair of auxiliary furnaces at each longitudinal opening end of the main furnace to save heat calories and provide a uniform heating region throughout the reaction chamber (col. 1, l. 60-col. 2, l. 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
