摘要:
A coating film comprises an amorphous carbon of a specified atomic ratio with respect to hydrogen and carbon and it is excellent in hardness, oxidation resistance, thermal resistance, electric resistance and thermal conductivity. The coating film is produced by sputtering a graphite target electrode in an atmosphere of hydrogen, fluorine or a mixture of hydrogen and fluorides having a gas pressure of 6.665 to 666.5 Pa (0.05 to 5.0 Torr) while maintaining the relative current density for the graphite target electrode and a power source between 11.3 and 14.7 ma/cm.sup.2 thereby limiting the H/C ratio in terms of an atomic ratio between 0.5 and 0.9. A sputtering apparatus used for producing such coating film includes a coating forming deposition substrate arranged at a position within a sputtering vacuum container which is not directly exposed to a plasma or a deposition substrate mounted on an electron drawing electrode within the container and a plasma adjusting electrode positioned in front of the substrate.

A heavy oil emulsified fuel combustion furnace is provided which prevents lowering of combustion efficiency due to water content in the fuel as well as prevents elevation of sulfuric acid dew point due to water content in the flue gas of the combustion furnace. In the apparatus a heavy oil emulsified fuel (102) is heated by a heater (110) using a heat pipe etc. and then is separated by a water vaporizer (120) into heavy oil (122) and vapor (121) consisting of steam and a light oil combustible gas. The heavy oil (122) is supplied to a burner port of the combustion furnace, such as a boiler etc. The vapor (121) is condensed by a condenser (140) to produce liquid (141) comprising a mixture of water and light oil. The liquid (141) is separated by an oily water separator (150) into oil (151) and water (152). The oil (151) is used as a fuel for an igniting torch of the combustion furnace 10 and the water (152) is used partially as cooling water (41) for an SO.sub.X removal apparatus (40) and partially as an atomizing steam 9 or a soot blowing steam 8 in the boiler, etc.

摘要:
The principal objects of the invention is to provide diamond fine particles with a surface nature so improved as to form a stable, uniform suspension or dispersion in a common medium such as water and alcohol. Another object is to provide an effective technique for producing hydrophilic diamond fine particles by chemically modifying the particle surface nature, while removing at the same time contaminants and foreign materials which coexist with the diamond. In the invention, diamond particles are treated by boiling in the treatment fluid of sulfuric acid solution, which is in particular of concentrated or fuming nature, at a temperature more than 200° C., which is preferably 250° C. or more.

A carbon film of the present invention has an elongated needle shape whose radius decreases toward a tip. The shape is, preferably, a shape in which a field concentration coefficient β in the Fowler-Nordheim equation is expressed by h/r where r denotes the radius in an arbitrary position and h denotes height from the arbitrary position to the tip.
