摘要： PURPOSE:To reduce stress generated at a wind hole portion and to improve fatigue strength by decreasing the wall thickness in the periphery of the wind hole formed on a disc to be wedge-shaped in section, and setting the decreased wall portion in such a manner as to satisfy specified dimensional relationship. CONSTITUTION:A wheel comprises a rim for holding a tire and a disc to which a hub is fitted. A wind hole 20 or the like is formed on a disc raw material 20. In this case, the disc raw material 20 has a wall thickness in the periphery of the wind hole 21 decreased to form a wedge-shaped section, and the decreased wall portion is set in such a manner as to satisfy the following conditions. That is, when half the shortest distance between the adjacent wind holes 21 is supposedly l0, the width of the decreased wall portion l1, the wall thickness of the disc raw material 20 h0 and the wall thickness of the end portion of the wind hole 21 h1, for example, if l1/l0 +0.95.

摘要： PURPOSE:To obtain a wear resistant member having excellent shock resistance by arranging composite layer of ceramic and metal on surface of a metal-made basic body. CONSTITUTION:A forming mold 7 is made by forming a carton, and alumina quality ceramic grain 6 kneading ceramic adhesives is filled in the mold 7 and hardened, and the ceramic grain bonded body 9, which make it the composite layer shape, is taken out from the mold 7 and dried and burnt. Next, the ceramic grain bonded body 9 is fixed to the position corresponding to the composite layer in a cavity in a mold 10, and after preheating the ceramic grain bonded body 9 and the mold 10 by mixing gas of town gas and compressed air from a casting inlet 11 and feeding headers 12, molten cast iron is poured from the casting inlet 11. And, permeation of the matrix metal into the ceramic grain bonded body and casting to the remaining part of the mold cavity are executed at the same time, and the wear resistant member 1 arranging the composite layer 3 on the surface of the basic body 2 and having excellent shock resistance is cast.

摘要： PURPOSE:To secure the strength of thread especially male thread by making the winding angle of reinforcing fiber in a thread-forming part equal to the lead angle of thread to be formed and keeping continuous fiber existent even after threading operation. CONSTITUTION:Reinforcing fiber obtained by impregnating synthetic fiber is wound around a mandrel M at an angle theta=20-70 deg. to form a tube. As a result, the strength of a base material in an axial and a circumferential direction is assured. Next, a resin-impregnated fiber 2 of the same material as the base material 1 is wound around the base material 1, thus forming a fiber-oriented part for thread-formation. The resin-impregnated fiber 2 is wound around the base material 1 at the lead angle theta of thread to be formed on the way forward of shuttle operation for winding fiber. On the way back, the angle is -theta. The lead angle is generally 0.1-5 deg.. Therefore, if the thread were cut, a continuous fiber remains intact from root to crest of thread.
摘要翻译：目的：通过使螺纹形成部分中的增强纤维的卷绕角度等于要形成的螺纹的导程角，即使在穿线操作之后，也能保持连续的纤维，从而确保螺纹特别是阳螺纹的强度。构成：通过浸渍合成纤维获得的增强纤维以角度θ= 20-70度缠绕在心轴M上。以形成管。结果，确保基材在轴向和圆周方向上的强度。接下来，将与基材1相同材料的树脂浸渍纤维2缠绕在基材1上，从而形成用于线形成的纤维取向部。树脂浸渍的纤维2以在要缠绕纤维的往复操作的前进道路上形成的螺纹的导向角θ缠绕在基材1上。在回去的路上，角度是-the。导程角通常为0.1-5度。因此，如果螺纹被切割，则连续纤维从根部到螺纹顶部保持完整。

摘要： PURPOSE:To prevent waved deformation and cambering bent deformation of web by forcedly cooling while moving by holding both surfaces of the flange parts of H-shape steel which is delivered from a finishing mill. CONSTITUTION:The flange parts 2 of H-shape steel 1 which is passed through the finishing mill 4 are held from both side faces with guide shoes A, B, C, D and pressurized with hydraulic cylinders 6. While moving a lower frame 7 in the rolling direction at a speed that is synchronized with a delivering speed of the H-shape steel 1, the flanges 2 are forcedly cooled by injecting cooling water from cooling nozzles 10 to the flange parts 2. Because the flanges 2 is thermally shrinked, friction force (force of constraint) in the direction that thermal shrinkage of the flanges 2 is prevented is acted on the contact surface between the guide shoes A-D and the flanges 2. Thermal stress that is generated on the flanges 2 due to this force of constraint is acted as strong tensile stress. Because the difference between the thermal shrinkage of the flanges 2 and the web 3 is mitigated and compressive stress that is generated on the web 3 is reduced, the generation of waved deformation of the web 3 is prevented.
