摘要： After insertion of a mandrel (23) into a blank tube (20) in the form of an electric welded tube, a parallel swaging operation is carried out by moving a cylindrical die (24) to cause the end of the blank tube (20) to contact tightly with a parallel forming portion (27) of the mandrel (23). After completion of parallel swaging operation, the die (24) is withdrawn out of the blank tube (20) and a push-die (33) is caused to move to the blank tube (20) from a radially outward position while leaving the mandrel (23) inside the blank tube (20) so that a weld bead on the blank tube (20) can be flattened by cooperation with the mandrel (23).
摘要翻译：在以电焊管的形式将芯棒（23）插入空管（20）之后，通过移动圆柱形模具（24）以使空管（20）的端部移动，进行平行的模锻操作，与心轴（23）的平行形成部分（27）紧密接触。在平行锻造操作完成之后，将模具（24）从空白管（20）中取出，并且使推模（33）从径向向外的位置移动到坯料管（20），同时留下心轴（23）内，使得坯料管（20）上的焊缝可以通过与心轴（23）协作而变平。

摘要： A shock absorber includes first passages configured to communicate two chambers to flow a working fluid therebetween by movement of a piston, and a second passage configured to communicate with one chamber of the two chambers. The first passages have damping valves configured to suppress a flow of the working fluid generated by movement of the piston to generate a damping force. The second passage has a variable orifice having an area adjusted by an elastic member when a piston rod moves in an extension direction, a pressure chamber installed in series with the variable orifice, and a free piston configured to vary a volume of the pressure chamber by movement of the piston.

摘要： A piston connected with a piston rod is slidably fitted in a cylinder having a hydraulic fluid sealed therein. An extension-side main disk valve generates a damping force in a high piston speed region against the flow of hydraulic fluid in an extension-side passage. A sub-passage bypasses the extension-side main disk valve, and an extension-side sub disk valve generates a damping force in an intermediate piston speed region. A compression-side main disk valve generates a damping force in the high piston speed region against the flow of hydraulic fluid in a compression-side passage. A sub-passage bypasses the compression-side main disk valve, and a compression-side sub disk valve generates a damping force in the intermediate piston speed region. Damping force characteristics in the intermediate and high piston speed regions can be set according to the valve-opening characteristics of these disk valves. Therefore, it is possible to increase the degree of freedom for setting damping force characteristics.
