摘要： PROBLEM TO BE SOLVED: To solve such a conventional problem that, although cemented carbide is a high hardness and high toughness material and various trace elements including vanadium carbide (VC) are added to bring out its performances, the grain size of a raw material prepared by pulverizing a carbide become large when the vanadium carbide (VC) is used and, as a result, uniform improvement of properties in a product cannot be done.
SOLUTION: One of component materials of a stock for a tool, such as a hob, is replaced from a carbide to vanadium trioxide (V
2 O
3 ) as an oxide. Since vanadium oxide is softer than vanadium carbide, vanadium oxide can be easily reduced in particle size in a mixing step using a ball mill in the course of raw material blending. The hardness of cemented carbide after sintering can hereby be increased by the effect of the vanadium trioxide uniformly dispersed in the raw material.

摘要翻译：要解决的问题为了解决这样一个常规问题，尽管硬质合金是高硬度和高韧性的材料，并且添加了包括碳化钒（VC）在内的各种微量元素以提高其性能，但是其粒径当使用碳化钒（VC）时，通过粉碎碳化物制备的原料变大，结果不能使产品的性能得到均匀的提高。
解决方案：用于工具的坯料（例如炉刀）的组分材料之一被碳化物替换为三氧化二钒（V 2 SB 3 O 3 / SB 3），作为氧化物。由于氧化钒比碳化钒软，所以在原料混合的过程中，使用球磨机的混合工序中的氧化钒粒径容易降低。因此，通过均匀分散在原料中的三氧化二钒的效果，可以提高烧结后的硬质合金的硬度。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a ceramic porous body having independent pores uniform in diameter.
SOLUTION: Foam is incorporated into a slurry obtained by kneading a ceramic powder and water. The foam is generated by passing a foaming agent through a mesh to foam and has a uniform diameter. The slurry in which the foam is incorporated is kneaded, cast and molded. The ceramic porous body is manufactured by taking the molded article out of a mold and sintering (baking) the same. The ceramic porous body has pores which are the trace of the foam. Each pore is circular and independent of each other. So, the ceramic porous body has good heat insulation properties.

摘要： PROBLEM TO BE SOLVED: To obtain highly refined fly ash by recovering an unburned portion effectively with regard to a method for refining fly ash and refined fly ash powder. SOLUTION: Crude fly ash 1a containing unburned portion of coal is introduced into a coarse screening apparatus 2, and the fly 1b on the screen is discharged from a discharge opening 2b. The fly ash 1c under the screen which has passed through the apparatus 2 is discharged from a discharge opening 2c to a fine screening apparatus 3a and introduced from a discharge opening 2b into a fine screening apparatus 3b to be classified from discharge openings 4a, 4b into the fly ash on the fine screen and the fly ash 2e under the fine screen. Since the resistance of the fine screening apparatuses is large, the apparatuses 3a, 3b are installed in parallel, and ultrasonic vibrators 3a1, 3a2 are installed to prevent the lowering of treatment efficiency by clogging. The fly ash 1b under the course screen containing the unburned portion is obtained from the discharge opening 2b, and high by refined fly ash 1e under fine screen is obtained.

摘要： PROBLEM TO BE SOLVED: To improve sealing performance, to prevent the intrusion of ash into a sealing part and to prevent the fixing of a slider in a seal structure of the ceramic filter of a dust collector applied to a coal-gasified combined power generating system. SOLUTION: A weight sleeve 3 is placed on the upper end of a ceramic tube 1 through a gravity seal 2 and surrounded by a main body 4, a sealing part 5, a cylindrical ring 13, a mount 12 and an upper cylindrical member 15 are integrally connected within the main body 4 through the flange faces fastened to each other by bolts and nuts 16. A sealing member 6 is inserted between the outer periphery of the tip of the weight sleeve 3 and the inner periphery of the sealing part 5 and made slidable through the sliding member 6 when a thermal elongation difference is produced between the weight sleeve 3 and its outside structure. A ceramic bag 10 is fixed to the weight sleeve 3 tip via bolts 11 and to the outer periphery by the mount 12 through the bolts and nuts 16, hence ash does not intrude into the clearance at the sealing part, the fixing of the sealing part is prevented, the sealing performance is improved, and the thermal elongation is also absorbed.

摘要： PROBLEM TO BE SOLVED: To obtain a material for a combustion device having high temp. corrosion resistance and oxidation resistance by thermally spraying a thermal spraying material having a specified compsn. on an Ni base alloy as a base metal. SOLUTION: As the Ni base alloy as a base metal, 45Cr-30Ni-Fe, 50Cr-50Ni, McAlloy, inconel 625 or the like are used. As the thermal spraying material, the one obtd. by mixing CoNiCrAlY (e.g. by weight, 30 to 50% Co-25 to 35% Ni-15 to 25% Cr-3 to 10% Al-0.3 to 0.7% Y) with Cr2 C2 ) good in corrosion resistance so as to be regulated to 20 to 90% is used. Furthermore, the Ni base alloy as the base metal is subjected to calorizing treatment to obtain a material for a high temp. corrosion-resistant combustion device. The calorizing treatment is the one in which Al is subjected to pack cementation to the surface of the base metal to increase the concn. of Al effective for the corrosion resistance only of the surface of the base metal, and is generally executed in such a manner that the base metal is buried in Al2 O3 -NH4 Al powder including Al, and heating treatment is executed in a reducing gas.
