摘要： PROBLEM TO BE SOLVED: To obtain a metal-ceramics composite in which the time required for penetration of a metal is shortened and an Al2 O3 powder minimal in the occurrence of metal-vein is used as a reinforcement. SOLUTION: A preform is prepared by using ceramic fibers or grains as a reinforcement and a metal as a base material is allowed to penetrate into the preform, by which the metal-ceramics composite is produced. In this method, the preform is prepared by adding, as a binder, 1-10 pts.wt. of inorganic powder composed essentially of alumina-silica and having 0.1-100 μm average grain size to 100 pts.wt. of Al2 O3 powder having 1-150 μm average grain size, molding the resultant powder mixture, and then burning the resultant molded part at 1100-1500 deg.C for 1-5 hr. Subsequently, an alloy composed essentially of aluminum is allowed to penetrate into the resultant preform at 700-1000 deg.C.

摘要： PROBLEM TO BE SOLVED: To detect the presence/absence of pinholes in an object to be inspected and, at the same time, to prevent the object from being damaged by electric discharge. SOLUTION: The impedance XC1 of the capacitance C1 between a first electrode 2a and the content 1b of a packaging material 1a becomes smaller when the packaging material 1a has pinholes. Since the output voltage V of a piezoelectric transformer 4 becomes smaller due to the output characteristic of the transformer 4 when the impedance XC1 becomes smaller, the presence/ absence of the pinhole can be discriminated by detecting the fluctuation of the output voltage V by means of detecting resistors 5a and 5b and comparing the detected fluctuation with a reference voltage by using a rectifier circuit 6 and a voltage comparing circuit 7.

摘要： PROBLEM TO BE SOLVED: To prevent a foaming fire resistant painting film layer of a steel frame column at the time of temperature increase by extending a fire resistant covering material layer formed on the surface of a steel frame beam and covering the upper end of the foaming fire resistant painting film layer formed on the surface of the steel frame column. SOLUTION: A foaming fire resistant painting film layer is formed on the surface of a steel frame column, and the surface of a steel frame beam is covered by a cement-based fire resistant covering material layer, which is extended, and the surface of the upper end A1 of the foaming fire resistant painting film layer formed on the surface of the steel frame column is covered by a fire resistant covering material layer A2. In addition, in the case where the foaming fire resistant painting film layer is formed on the steel frame column and the steel frame beam, the fire resistant covering material layer is formed on the surface of the foaming fire resistant painting film layer in continuity with the steel frame column and the steel frame beam in the neighborhood of a corner part. Therefore the foaming fire resistant painting film layer of the surface of the steel frame column sandwiches the upper end A1 between the steel frame column and the fire resistant covering material layer A2, even if the foaming fire resistant painting film A1 is softened at the time of temperature increase, it is prevented from being hung by self weight, and a uniform thick porous heat insulation layer can be foamed and formed on the surface of the steel frame column.

摘要： PROBLEM TO BE SOLVED: To provide a method for purifying water quality which can be relatively inexpensively performed by using porous concrete and further gives purifying capacity making more rapid progress compared with the conventional case where porous concrete is used alone. SOLUTION: Porous concrete blocks and phosphorus adsorbent blocks which a mixture of volcanic ashes and iron (II) sulfate is sintered to form are installed in water. Porous concrete is used with a phosphorus adsorbent to give synergistic phosphorus removing action. There is no limit to the size and shape of the blocks, and for example, they are installed in water or at the water's edge as riverbed blocks, shore protection blocks, or fish gatheringplace blocks. And the porous concrete blocks and the phosphorus adsorbent blocks may be integrated.

摘要： PROBLEM TO BE SOLVED: To maintain productivity even when molding is performed under high speed centrifugal force, prevent limewash from developing, and realize the revelation of high strength by a method wherein a concrete kneaded matter, which includes specified amounts of acid clay and of water-soluble polymeric substance and the slump of which lies within a specified range, is centrifugally molded. SOLUTION: A concrete kneaded matter, which includes 2.5-10kg/m of acid clay and 0.01-0.2kg/m of water soluble polymeric substance having a thickening action and the slump of which is 13.0cm or less, is centrifugally molded. The acid clay is mainly made of aluminum silicate. The acid clay employed is made of montmorilonite as its major mineral. As the water soluble polymeric substance having a thickening action, an acrylic amide-based compound such as polyacrylic amide, polymethacrylic amide or the like, a cellulose-based compound such as methyl cellulose, carboxy methyl cellulose, hydroxy ethyl cellulose or the like and microbial fermented polysaccharides are employed.
