Abstract:
PROBLEM TO BE SOLVED: To provide a shaping method for a surface using gas plasma. SOLUTION: An apparatus (106) and the methods for reactive atom plasma processing can be used to shape, polish, planarize, and clean the surface of material with minimal subsurface damage. The workpiece (110) and a plasma torch (502) are moved with respect to each other. Plasma discharge from the torch (502) can be used to shape, planarize, polish, clean and/or deposit material on the surface of the workpiece (110). COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a system and an apparatus utilizing plasma heat energy. SOLUTION: While a feeding path 4 for gaseous nitrogen, water or the like formed between a plasma electrode 2 and a minus electrode 3 in a plasma torch 1 is fed with raw materials such as gaseous nitrogen, air and water; a discharge is generated between the plus electrode 2 and the minus electrode 3 to take out plasma heat energy 5. The plasma heat energy taken out is used to perform soldering. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
A device for producing plasma includes an isolating pipe formed of an isolating material, a rod-shaped conductor positioned inside of the pipe, the rod-shaped conductor having an inner diameter that is smaller than the diameter of the of the isolating pipe, and an inner alternating electromagnetic field source connected to a first end of the conductor. The device also includes a conductive pipe positioned inside of the isolating pipe and concentrically around the conductor, the conductive pipe being formed so as to partially enclose the conductor, and an outer alternating electromagnetic field source connected to a first end of the conductive pipe.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently and completely decomposing an organic halogen compound regardless of components with a small size apparatus and one apparatus, and an apparatus. SOLUTION: In the decomposition method for the organic halogen compound and its apparatus, the organic halogen compound such as chlorofluorocarbon and perfluorocarbon (PFC) is mixed with flammable substances such as methanol and liquefied petroleum gas and the obtained mixture is subjected to a plasma treatment at a high temperature using a thermal plasma device 40 having a discharge electrode to decompose the organic halogen compound.
