    摘要： An object of the present invention is to provide a brass alloy, in which the content of Bi is reduced to secure a good recyclability while maintaining the dezincification corrosion resistance required for a member for water works, and which is capable of exhibiting an erosion-corrosion resistance and excellent mechanical properties to be used as a member for water works. This brass alloy contains: 24% by mass or more and 34% by mass or less of Zn; 0.5% by mass or more and 1.7% by mass or less of Sn; 0.4% by mass or more and 1.8% by mass or less of Al; 0.005% by mass or more and 0.2% by mass or less of P; and 0.01% by mass or more and 0.25% by mass or less of Pb; with the balance being copper and an unavoidable impurity(ies). Note, however, that in cases where the above mentioned copper alloy has a content of Sn of less than 1.0% by mass, the contents of Al and Sn in % by mass satisfy the Inequality: Al + 2 × Sn ‰¥ 2.8.

    摘要： A kneader/stirrer is provided which has a high self-cleaning ability and can be operated for a long period of time. The kneader/stirrer includes two rotary shafts (4) extending parallel to each other in the processing chamber (2), first regular triangular impellers (3) mounted to one of the rotary shafts (4) so as to be arranged in the axial direction of the rotary shaft (4), and second regular triangular impellers (3) mounted to the other rotary shaft (4) at the same axial positions as the respective first impellers (3). The impellers (3) are fixed to the respective rotary shafts (4) at points offset from the centers of the respective impellers (3) in a predetermined direction by a predetermined distance such that when the two rotary shafts (4) rotate in the same direction at the same speed, each pair of first and second impellers (3) are eccentrically pivoted, with one apex of one of the pair of impellers kept in contact with or in close proximity to the contour of the other impeller, thereby scraping off polycondensation resin (material to be processed) adhered to the other impeller, while scraping off resin adhered to the inner wall of the processing chamber (2) with one of the apexes nearest to the inner wall. Thus, this device has a higher self-cleaning ability than conventional devices using disk-shaped impellers, and thus can be stably operated for a long period of time.

    摘要： A first metal sheet (1) is placed on a backing metal plate (6), and an end portion of a second metal sheet (2) is placed on top of an end portion of the first metal sheet (1) such that the ends of the end portions are spaced apart from each other by a predetermined distance in side view. The end portions of the first and second metal sheets (1) and (2) are joined together by downwardly pressing a rotating rotary tool (4) onto the end portion of the second metal sheet (2) placed on top of the end portion of the first metal sheet (1) and by utilizing frictional heat and pressurizing force generated between the rotating tool and the first and second metal sheets (1) and (2).
