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.

A production process which comprises a preform formation step of forming a fiber preform made of silicon carbide short fibers having heat resistance of 1000 C. or greater; a sol-gel preparation step of preparing a sol-gel solution containing a heat resistant compound having heat resistance of 1000 C. or greater; an impregnation-drying-calcination step of impregnating the fiber preform with the sol-gel solution, followed by drying and calcining; and a crystallization step of crystallizing the fiber preform after impregnation, drying and calcination.

A plasma CVD method uses an electrode array in a reaction chamber, the electrode array including a plurality of inductively coupled electrodes, each electrode being folded back at the center so that each electrode is substantially U-shaped with two parallel straight portions, the electrodes are arranged such that all of the parallel straight portions are arranged parallel to each other in a common plane, each of the electrodes having at least a portion with a diameter of 10 mm or less, and a phase controlled power supply for feeding high frequency power to the feeding portions so as to establish a standing wave of a half wavelength or natural number multiple of a half wavelength between a feeding portion and a folded back portion and between a grounded portion and the folded back portion, and is controlled to have a phase difference between adjacent two feeding portions.

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.
