摘要： PURPOSE:To improve the reinforcement effect by compounding carbon fibers applied with a water replacement treatment replacing gas caught with the fibers with water, as a reinforcing agent in a cement matrix. CONSTITUTION:Carbon fibers, preferably carbon fibers having a hydrophilic active group with 0.5-20mm fiber length are subjected to a water replacement treatment for gas such as air caught with the fibers by dipping them into water for 3-7 day. Then, 1-20vol.% fref., 1-10vol.% of the carbon fibers are compounded to the cement matrix obtained by mixing additives of an aggregate, an AE agent, a water reduction agent, etc., with a cement such as a rapid hardening Portland cement, and they are kneaded with a high power mixer and dispersed, thus the carbon fiber reinforced cement system material having the strong fiber reinforcement effect is obtained.

摘要： PURPOSE:To provide a silicon-containing carbon fiber having excellent dispersibility in cement matrix and extremely high fixability to cement matrix and capable of easily giving a CFRC having high fiber-reinforcing efficiency. CONSTITUTION:An aqueous solution of a polymeric compound composed of an aromatic sulfonic acid or its salt bonded through methylene-type bond is incorporated with 0.04-4.0wt.% (based on the polymeric compound in the solution) of fine silica particles and, as necessary, a spinning assistant to obtain a spinning dope. The objective carbon fiber is produced by spinning the dope and carbonizing the obtained precursor fiber by heat treatment.

摘要： PURPOSE:To produce an extrusion molded object composed of a ceramic material while preventing the sagging of the over hang part formed to the extrusion molded object. CONSTITUTION:The raw ceramic material introduced into a mold 23 is extruded from the outlet part 0 of a molding space part so as to have the outer shape containing even the lower part D of the overhang part Wo of an extrusion molded object W but, at this time, a slit 71 is provided to the boundary part of the overhang part Wo and the lower part D by the knife member provided to the outlet part 0 of the molding space part and the raw material is extruded in such a state that the extrusion molded object W and the lower part D are cut. The extrusion molded object W is produced while the overhang part Wo of the extrusion molded object W extruded from the outlet part 0 of the molding space part is held by the lower part D extruded along with the extrusion molded object W.

摘要： PURPOSE:To easily and surely form the projecting part for increasing the adhesion force of a packing material by inserting the tubular body for a joint hardware to the shape that plural projecting bar parts are formed on the inner face and pouring a super high pressure water inside the tubular body. CONSTITUTION:The tubular body 5 for a joint hardware is inserted into the inner part of a shape 4, urethane is expanded by compressing the urethane of both closed parts 6, 6 and both end parts of the tubular body 5 are closed. When an extra high pressure water is poured into a feeding hole 10 from a center hole jack 14 side, it is poured between both closed parts 6, 6 inside the tubular body 5 from each pouring hole 7. And when the water pressure inside the tubular body 5 is increased, the tubular body 5 is pressed and deformed along the shape of the shape 4. The tubular body 5 is thus made a joint hardware with the plural projecting part for increasing the adhesion force of a packing material corresponding to the projecting bar part 2 of the shape 4 being formed on its inner face.

摘要： PURPOSE:To easily form the projecting part formed on an inner face by pressing by abutting to the outer peripheral face of a tubular body the inner face of the tubular shape forming the projecting bar part extending in the peripheral direction on the inner face and divided in plural pieces. CONSTITUTION:The shape 1 inside an outer peripheral ring 3 is made in the state of a projecting bar part 2 being expanded at its diameter and the tubular body 6 for joint hardware is inserted into this shape 1. When the shape 1 is then moved, the projecting bar part 2 of the shape 1 is contracted at its diameter by the action of the moving face 4 becoming of a tapered face. The outer peripheral face of the tubular body 6 inside the shape 1 is therefore pressed by the projecting bar part 2, which is bitten to the outer peripheral part of the tubular body 6 and the projecting part 7 corresponding to the projecting bar part 2 is formed on the inner peripheral face of the tubular body 6. The shape 2 is then moved, the tubular body 6 is moved by expanding the projecting bar part 2 and the forming work of the projecting part 7 is performed once again. Plural projecting parts 7 are formed on the inner peripheral face by repeating this work in order and a joint hardware 5 is completed.
