摘要： Agitation shafts provided with agitation vanes at lower portions thereof are fastened rotatably to the outer circumferential surface of a support cylinder to form a soft ground hardening machine. Connecting means are provided between upper and lower portions of the support cylinder. The connect-means are adapted to be tensed and slackened for eliminating the inclination of the machine in operation. In a soft ground hardening method using this machine, the inclination thereof can be eliminated as the direction in which the machine is inserted into or withdrawn from the soft ground is measured momentarily.

摘要： Agitation shafts provided with agitation vanes at lower portions thereof are fixed rotatably around a support cylinder to form a soft ground hardening machine. A direction control unit is provided at a lower portion of the support cylinder so as to control the direction in which the machine is inserted into and withdrawn from the soft ground. In a method of hardening the soft ground by using this machine, the direction in which the machine is inserted into and withdrawn from the soft ground is controlled as the direction in which the machine is being inserted into or withdrawn from the soft ground is measured.

摘要： A method for producing suspension parts via preforming the workpiece by roll forming. The sectional area and length of the workpiece are calculated. In the former step, more than one orthogonal cross-section is acquired from the suspension part of aluminum alloy, and the sectional area is converted into the area of a circle. An imaginary area is calculated by adding to the converted area an adequate amount of flash. In the latter step, a circular truncated cone is defined from two adjacent imaginary circles and the length of the imaginary center line between the two adjacent imaginary circles. A solid of revolution is defined by connecting these circular truncated cones, and the volume of the suspension part of aluminum alloy is substituted by the volume of the solid of revolution. The value obtained by dividing the sectional area of the workpiece by the volume is regarded as the-length of the workpiece.

摘要翻译： 一种通过辊轧成型预成形工件来制造悬挂部件的方法。 计算工件的截面积和长度。 在前一步骤中，从铝合金的悬挂部分获取多于一个正交横截面，并将截面积转换成圆的面积。 通过向转换的区域添加足够量的闪光来计算虚拟区域。 在后一步骤中，圆形截锥体由两个相邻的假想圆和两个相邻虚圆之间的假想中心线的长度定义。 通过连接这些圆形截锥体来限定旋转实体，铝合金的悬挂部分的体积被旋转体积的体积所代替。 通过将工件的截面积除以体积而获得的值被认为是工件的长度。
