Abstract:
A method for inducing chemical reactions using X-ray radiation comprises generating an irradiation voiume within the interior of a reaction vessel by introducing X-ray radiation into the volume, in which two or more reactants are introduced, With respect to the two or more reactants and any subsequentiy created intermediate reactani or reactants, the aggregate extent to which the foregoing reactants are to be ionized to any degree is selectively controlled, and the average degree of ionization in the irradiation volume, from partial to total, of that portion of the foregoing reactants which is to be ionized is selectively controlled, through control of the fiuence and energy of the X-ray radiation, to thereby induce selective reactions of reactants to occur in the irradiation volume. One or more reactants may be delivered through a double-wailed pipe containing X-ray shielding to prevent their premature irradiation before being infected into the irradiation volume.
Abstract:
In a method for irradiating an active energy ray wherein an article to be irradiated is conveyed in from an entrance, the article is irradiated with an active energy ray under an inert gas atmosphere in an active energy ray irradiation section and then the article is carried out from an exit, an improvement which comprises controlling the resistance to gas flow at the entrance and the exit in such a manner that the article is irradiated under a condition wherein X/Y ≥1, where X represents the amount of a gas passing through the entrance and Y represents the amount of a gas passing through the exit.
Abstract:
A reactor including a rotatable disc (3) having a trough (13) in an upper surface (5) thereof. Reactant (15) is supplied to the trough (13) by way of a feed (4), the disc (3) is rotated at high speed, and the reactant (15) spills out of the trough (13) so as to form a film (17) on the surface (5). As the reactant (15) traverses the surface (5) of the disc (3), it undergoes chemical or physical processes before being thrown from the periphery of the disc (3) into collector means (7).

Abstract:
The molecular etcher carbonyl fluoride (COF2) or any of its variants, are provided for, according to the present invention, to increase the efficiency of etching and/or cleaning and/or removal of materials such as the unwanted film and/or deposits on the chamber walls and other components in a process chamber or substrate (collectively referred to herein as "materials"). The methods of the present invention involve igniting and sustaining a plasma, whether it is a remote or in-situ plasma, by stepwise addition of additives, such as but not limited to,. a saturated, unsaturated or partially unsaturated perfluorocarbon compound (PFC) having the general formula (CyFz) and/or an oxide of carbon (COx) to a nitrogen trifluoride (NF3) plasma into a chemical deposition chamber (CVD) chamber, thereby generating COF2.
Abstract:
A reactor produces a gas-in-liquid emulsion for providing increased interfacial contact area between the liquid and the gas for improved reaction of the gas with the liquid, or more rapid solution or reaction of a difficulty soluble or immiscible gas in or with a liquid. The reactor is suitable for a continuous or batch type process. Rotor and stator cylindrical members are mounted for rotation relative to one another and have opposing surfaces spaced to form an annular processing passage. The gap distance between the opposing surfaces and the relative rotation rate of the cylindrical members are such as to form a gas-in-liquid emulsion of the gas in the liquid. The liquid and gas pass through the processing passage, changing into the gas-in-liquid emulsion.
Abstract:
An electromagnetic irradiation device comprises an electromagnetic source (13) such as an ultraviolet lamp; a cylindrical member (15) enclosing the electromagnetic source; a liquid tank provided outside the cylindrical member (16); and an opening (17) for allowing the overflow from the tank to fall in the form of thin film along the inner wall of the cylindrical member, which is irradiated by a lamp (11). Means is provided for allowing the liquid through the opening (17) to fall spirally along the inner wall of the cylindrical member. The irradiation device achieves stabilized electromagnetic irradiation of large amounts of liquid without causing the contamination of an electromagnetic source such as an ultraviolet lamp.

A reactor including a rotatable disc (3) having a trough (13) in an upper surface (5) thereof. Reactant (15) is supplied to the trough (13) by way of a feed (4), the disc (3) is rotated at high speed, and the reactant (15) spills out of the trough (13) so as to form a film (17) on the surface (5).

Abstract:
A reactor including a rotatable disc (3) having first (5, 19) and second (20, 30) surfaces. Reactant (15) is supplied to the first surface (5, 19) by way of a feed (4), the disc (3) is rotated at high speed, and the reactant (15) forms a film (17) on the surface (5, 19). As the reactant (15) traverses the surface (5, 19) of the disc (3), it undergoes chemical or physical processes before being thrown from the periphery of the disc (3) into collector means (7). Means for supplying a heat transfer fluid (35) to the second surface (20, 30) are also provided so as to allow the first surface (5, 19) and hence the reactant (15) to be cooled or heated.
