Abstract: A ceramic composite material is comprised of a fabric of fibers of an inorganic substance; and a matrix for combining the fibers. The matrix consists essentially of a ceramic. The matrix is formed by burying the fabric in a mixture of a powder of carbon, a powder of silicon and a medium including an organic solvent, producing an oscillation in the mixture to impregnate the fabric with the mixture, and calcining the fabric impregnated with the mixture.

Abstract: In a method of reducing corrosion of a material constituting a nuclear reactor structure, an electrochemical corrosion potential is controlled by injecting a solution or a suspension containing a substance generating an excitation current by an action of at least one of radiation, light, and heat existing in a nuclear reactor, or a metal or a metallic compound forming the substance generating the excitation current under the condition in the nuclear reactor to allow the substance generating the excitation current to adhere to the surface of the nuclear reactor structural material, and by injecting hydrogen in cooling water of the nuclear reactor while controlling the hydrogen concentration in a feed water.

Abstract: The invention is a welding method capable of controlling an arc heat distribution on a groove face of a base metal, which comprises increasing or decreasing the melting rate of a welding wire relative to the feeding rate of the welding wire by changing the characteristic of an arc current to thereby change an arc generating position of a fusing end of the welding wire, wherein an AC arc welding operation is performed by changing the polarity of the welding wire as the characteristic of the arc current; and a welded joint structure formed by the welding method.

Abstract: A cell electrode plate is constituted by band-like core member made of metal foil and a plurality of sheets of electrode active material applied discontinuously on and longitudinally of at least one of upper and lower surfaces of the core member, the mutually adjacent sheets of the electrode active material having mutually different end positions widthwise of the core member. Thereby, an increase in worn amount of surfaces of press rolls is prevented when the cell electrode plate is pressed by a roll press machine with the press rolls so as to prolong the service life of the press rolls. Thus, the number and/or amount of grinding the press rolls is reduced to reduce the roll maintenance cost and enhance production efficiency.

Abstract: The invention aims at making a volatile organic compound harmless, and in addition comprehensively improving the energy efficiency within a facility where treatment of the volatile organic compound is necessary. In the invention, in order to achieve this aim, a solution means is adopted where, a discharge gas containing a volatile organic compound is supplied to an adsorption apparatus to adsorb the volatile organic compound in an adsorbent. The volatile organic compound is desorbed from the adsorbent with pressurized steam and mixed with the steam. The steam containing the volatile organic compound is supplied, in the pressurized state, to the combustion chamber of a gas turbine, and burned together with a fuel gas.

The antenna elements are arranged in plane in such a way that the first and second linear conductors are alternated and separated from one another at regular intervals, thereby forming one or more array antennas which are disposed in a chamber. The second ends of the first linear conductors are connected to a high-frequency power supply, and the second ends of the second linear conductors are connected to ground. A plurality of substrates are parallel placed on both sides of the array antennas at distances approximate to the distances between the linear conductors. A film is formed by introducing an ingredient gas into the chamber.
