摘要： PROBLEM TO BE SOLVED: To provide a method for maintaining the roughing state of an organic PTC sheet which can stably peel metal foil without generating a sheet crack in work for peeling the organic PTC sheet and the roughed metal foil before a metal electrode is formed, and to provide an apparatus for the method.
SOLUTION: A pretreating apparatus for forming the electrode includes a pair of rollers disposed above the front surface of the organic PTC sheet and below the rear surface of the organic PTC sheet to hold the metal foil peeled from the end of the sheet, and a pair of hot plates for holding the organic PTC sheet from above the metal foil. The pair of the rollers are rotated in a state that the organic PTC sheet is pressed by the hot plate, thereby continuously peeling the metal foil and feeding the organic PTC sheet.

摘要： PROBLEM TO BE SOLVED: To obtain a composite ceramic material having such airtightness as to be favorable for use in e.g. a heat exchanger which treats high-temperature gases. SOLUTION: The composite ceramic material is the one comprising a woven fabric made of a ceramic fiber and a matrix containing inorganic particles, wherein oxidatively expandable particles constitute a part of the inorganic particles. When the ceramic material is exposed to high temperatures during firing or use, the oxidatively expandable material is oxidized and expanded to fill fine gaps formed among the particles of the matrix and between the matrix and the woven fabric to realize enhanced airtightness.

摘要： PROBLEM TO BE SOLVED: To provide a method which optimizes an electron beam radiation condition for bridging and which can efficiently manufacture an organic PTC sheet element having a small resistance value change, a high switching temperature and excellent mechanical characteristics.
SOLUTION: The method for manufacturing the organic PTC element includes a step of holding the organic PTC sheet made of an organic resin material in which a conductive material is dispersed and which exhibits PTC characteristics. The method further includes steps of forming a metal electrode on the organic PTC sheet, and then radiating an electron beam of a radiation dose of 10-100 kGy at a radiating speed of 100-300 kGy/min to bridge the resin.

摘要： In a calcium silicate papermade board, inorganic fines (calcite, talc, gypsum, kaolin flyash, wollastonite, mica, vermiculite, magnesium hydroxide, aluminium hydroxide, allophane mordenite, magnesium carbonate or the like) are dispersed in a matrix and fibers, the fines comprising 10 to 33% by weight so that the value of the total strain in a bending test is not smaller than 4.0 x 10-3 and the ratio of the plastic strain to the total strain is not smaller than 50%. The board can be easily bent and easily fixed with nails. The fibres may be pulp or synthetic, eg. polypropylene.
