Title: Vapor deposition device
Inventor: NAKATANI HAJIME
IPC: C23C14/24
Filed: 1985-01-29
Abstract: PURPOSE:To prevent the decrease in the insulation around a crucible for a metal to be deposited by evaporation in a vapor deposition device and the make possible a stable vapor deposition operation by providing hole for discharging an evaporating material to the heat shield of the above-mentioned crucible. CONSTITUTION:The inside of a vacuum vessel 1 is evacuated to a vacuum and the crucible 2 contg. the metal 3 to be deposited by evaporation on a member 8 for vapor deposition is heated by a heater 4 to melt and evaporate the metal 3. The molten metal is ejected from a small hole 2a of the crucible 2. The ejected metallic vapor is ionized by the electrons generated from a filament 5. The ions are accelerated by an accelerating electrode 9 so as to collide against the surface of the member 8 and to form the film consisting of the evaporating metal on the surface. Part 3d of the evaporating metal 3a from the crucible 2 enters the inside of the box type heat shield provided to the outside periphery of the heater 4 and decreases the degree of vacuum of said part to deteriorate the insulation characteristic thereof and therefore the many discharge holes 21 are provided to the shield 20 to discharge the metal 3d to the outside of the shield 20. The unstableness of the vapor deposition effect on the member 8 owing to the generation of the electric discharge arising from the defective insulation is thus prevented.

Title: Removal of nitrogen oxide contained in coke furnace exhaust gas
Inventor: YOSHIDA MASAYOSHI
IPC: C10B21/00
Filed: 1978-02-20
Abstract: PURPOSE: A selected amount of NH 3  is introduced into coke furnace exhausted gas, and the mixed gas is contacted with catalyst, thereby to control the production of acidic ammonium sulfate and to effect a low cost, long life, high ratio NO removal.  
     CONSTITUTION: The temperature of coke furnace exhaust gas varies with time in the range of 150 to 280°C as caused by furnace change. Prior to introducing the exhausted gas into a catalytic layer, the gas NO content is measured by instruments such as a chemical luminescent type meter. Based on the NO content, NH 3  is added in an amount such that the molar ratio of NH 4 /NO be 0.4 or more and less than 1. The mixed gas is, then, contacted with the catalyst at 150 to 280°C. The process produces no observable acid ammonium salts which will deteriorate the catalyst, thereby to prolong the service life of the catalyst, assuring high denitration rate for long period of time.
