摘要： A method and apparatus utilizing a core is located at a central portion of a molten metal storing portion in a vertical semi-continuous mold. The molten metal is poured into the molten metal storing portion, and casting takes place with the inner diameter of a solidified distal portion of the molten metal being controlled by a distal portion of the core. This approach provides a reliable method for the manufacture of high-quality hollow billets which are free from internal defects.

摘要： Disclosed is a screen printing apparatus for screen printing the cream solder including a squeegee assembly (30) provided with comb blade members (35) and with solder leakage prohibiting guides (36). The comb blade members partition a cream solder (52) substantially vertically with respect to a contact slide surface between the squeegee (33) and the screen (21) to prevent the cream solder from passing in fluidity on the screen (21) in a direction substantially at right angles to the sliding direction as the squeegee sweeps and as the cream solder becomes twisted between the screen and the squeegee. The solder leakage prohibiting guides (36) prevent the cream solder from leaking to outside a printing sphere determined by the squeegee width.

摘要： A high durability taper tap for pipe threads which can cut threads in a pipe made of hard materials having hardness of approximately 50 HRC. The sum &Sgr;&ggr; of the width angle of cutters is large, approximately 130°, thereby achieving high strength and rigidity are achieved. Since rake angle of the cutting edge &agr; is approximately −20°, cutter angle &bgr; defined by the rake face and the peripheral relief becomes more than 90° so that the strength and rigidity of a cutting edge are enhanced. In addition, since a taper of the bottom of flutes is in a ratio of 1/16, approximately equal to that of the thread portion, the rake angle &agr; of all of the cutting edges 6 is uniform so that all of the cutting edges can equally cut the threads. Further, the diameter Df of the bottom of the flutes of the top end portion is approximately 60% of the smaller end of the thread portion, which is larger than that of the common tapping tool. Owing to this configuration, the taper tap for pipe threads having high strength, rigidity and hard wearing property can be achieved.

摘要翻译： 用于管螺纹的高耐久性锥形龙头，其可以在具有约50HRC的硬度的硬质材料制成的管中切割螺纹。 刀具宽度角度的总和大约为130°，从而实现了高强度和刚性。 由于切削刃α的前角约为-20°，由前刀面和周边凸起限定的刀具角度β大于90°，​​从而提高切削刃的强度和刚度。 此外，由于凹槽底部的锥度与螺纹部分的大小相等的1/16，所以所有切削刃6的前角α均匀，使得所有切削刃可以 同样切线。 此外，顶端部分的凹槽的底部的直径Df约为螺纹部分的较小端部的大约60％，大于普通攻丝工具的直径。 由于这种构造，可以实现具有高强度，刚性和耐磨损性的管螺纹锥形螺纹。
