摘要： PURPOSE:To increase combustion efficiency, by keeping high pressure higher than the atmospheric pressure in a furnace when combustion takes place, by completely sealing the feed section and the ask ejecting openings of a furnace, and by supplying air into the furnace with a large forced draft fan. CONSTITUTION:The title incineration equipment is constituted in such a manner that a forced draft fan of large capacity 5 is connected to a furnace 1, a secondary combustion chamber 6 and a tertiary combustion chamber 61 are provided on the downstream side of a furnace 1, cyclone dust collectors 7 are connected on the further downstream side of them, being interposed by a flue 62 and a venturi scrubber 63, and a stack is connected to them. A double top cover consisting of an inner lid 21 and an outer lid 22 is provided to the feed section 2 of a furnace 1, and high pressure is kept in the furnace by opening a compressed-air feed pipe 24 to a feed space 23 between both lids 21 and 22. The doors of an ash bin 3 are also made nearly in the same structure. Combustion gas is prevented from leaking out so that combustion can take place by keeping high pressure higher than the atmospheric pressure in the furnace by feeding air into the furnace 1 with the forced draft fan 5.

摘要： PURPOSE:To provide a synthetic resin model which is covered with a metal film, and to obtain accurate outline dimensions even if the film thickness is not uniform, by forming the metal film by means of a special process. CONSTITUTION:An original pattern 1 such as a wood pattern is provided as a model in which a plaster or a synthetic resin is filled to form a female die 2. A molten metal such as nickle is sprayed on to the inner surface of the die 2, thus forming a metal film 3. Then the inner surface of the metal film 3 is filled with a synthetic resin 4. Finally, the female die 2 is removed to obtain a model 5 that is covered with the metal film 3.
