摘要:
In a method for processing nitrogen oxide, nitrogen oxide is reacted with hydrogen azide. Oxygen and/or plasma is utilized to accelerate the reaction between nitrogen oxide and hydrogen azide. An apparatus for use in performing the nitrogen oxide processing method includes a reaction case in which an aqueous solution containing hydrogen azide is provided. Nitrogen oxide containing gas is introduced into the reaction case for reacting nitrogen oxide with hydrogen azide to reduce nitrogen oxide. A plasma generating unit may be provided for feeding plasma into the nitrogen oxide contained gas.

The present invention provides a carbon film that is remarkably excellent in current voltage (IV) characteristics. This is achieved by way of a carbon film structure, two or more carbon film assembly units 12 are formed on a substrate 10. The carbon film assembly units 12 comprise: a stem-like carbon film 14 which is made into a film in the shape of a long and thin needle; and a branch-like carbon film cluster 16 which is made into a film so as to surround the stem-like carbon film 14 from the halfway to the lower part of this stem-like carbon film 14. The stem-like carbon film 14 has the shape of a long and thin needle having a configuration which has a spiral streak-like step part 18 towards the distal end at the circumference face of a near tip and in which the radius becomes small as going to the distal end.

This field electron emission device comprises a linear conductor wire having concave/convex on its surface and an electron emitter having electron conductivity formed on the concave/convex surface of the conductor wire. Preferably, the concave/convex is formed by a channeling performed to the surface of the conductor wire. Preferably, the electron emitter is composed of microscopic linear materials composed of selected one or combination of carbon nano-tube, carbon nano-wall, carbon fiber, graphite fiber, amorphous carbon fiber and diamond fiber.

Provided are an electron emitting body having a high electron beam density and an X-ray emitting device embedding the electron emitting body. The electron emitting body has a substrate, the surface of which forms a concave surface, and a carbon film comprising a large number of projections made of carbon and expanded two-dimensionally. The carbon crystal grows such that first a swell portion (22) gradually becomes larger and then a needle-like portion (23) grows from the head of the swell portion (22). The needle-like portion (23) has a graphene sheet obliquely wound therearound in a multi-layer fashion and has a hollow inside. The axis of a carbon projection (21) thus formed is substantially orthogonal to a line tangent to the concave surface (11), so that the axes of a plurality of the carbon projections (21) intersect with each other at the focal point (F) of the concave surface (11).

An electron emitter includes a guard electrode 13 on the outer circumferential side of a carbon film structure 10 which is formed on a substrate 7 by plasma CVD method. This guard electrode 13 includes a curved surface portion (a curved surface portion that curves from top toward a side opposite to the film-forming direction) 13a convex in a film-forming direction of the carbon film structure 10. A curvature radius R1 of an outer-circumferential-side portion of the curved surface portion 13a is larger than or equal to a curvature radius R2 of a carbon-film-structure-side portion of the curved surface portion 13a.

The purpose of the present invention is to provide a stereo x-ray radiation device that is small and for which handling is simple. One cathode that functions as an emitter and two anodes that function as targets are disposed in a single straight-tube shaped vacuum vessel. The stereo x-ray generating device is characterized by the cathode being a cold cathode disposed in the center part of the vessel, the anodes being disposed each to one end of the vessel, and the spaces between the anodes disposed in the two ends of the vessel and the cathode being constituted such that the same can be moved closer or apart along the axial line of the vessel.
