Abstract: When processing a female screw in a hole of a metallic material having the hole for female screw processing, a method includes forming a screw groove by sequentially pressing a processing portion of a male screw-shaped tool against an inner periphery of the hole only by a motion of a revolution of the male screw-shaped tool on a certain horizontal plane without rotation by itself in the state of gripping or fixing the metallic material to transfer a shape of the processing portion.

Abstract: The present invention provides method of fabricating components having internal teeth and rolling machine thereof, enabling large deformation at main rolling step omitting broaching step and step using gear shaper. A container having toughness against internal pressure as high as that of cold forging is provided instead of gripping mechanism of a cylindrical material. A cylindrical material is inserted into the rotatably driven container in aligned manner. A rotatably driving rolling tool is acted on the inner side to press the cylindrical material and distance between tool rotational shaft and container rotational axis is sequentially changed to successively grow tooth profile. A component having internal teeth filling the container is obtained by enlarging outer diameter by spreading. It is desirable to provide in advance the same number of concave grooves as that of internal teeth to be formed, at equal intervals on an inner circumferential face of the cylindrical material.

Abstract: An exposed aggregate finishing method for concrete. The method comprises coating the inside faces of a form for concrete with a cement setting retarder, drying, coating the dried faces with a synthetic organic polymer coating material which is soluble in an aqueous alkaline solution of cement, but is insoluble in water; and drying the coated faces. Alternatively, the method may be carried out by coating the inside faces of the form for concrete with the mixture of the cement setting retarder and the organic polymer coating material and drying the coated faces. Concrete is thereafter placed in the concrete form, the form removed and the surface of the molded concrete washed to make the surface rough.
