An object of the invention is to provide a fuel injector delivery pipe which does not require a tool for holding an upper part and lower part together, and thereby eliminate the process of attaching and removing the tool, and increases the efficiency of the operation. Furthermore, in order to achieve this object, the fuel injector delivery pipe comprises an upper part 2 with an inverted substantially U-shaped vertical cross-section in the longitudinal direction formed with a top wall 2a and two side walls 2b, 2b, and also comprises a lower part 3 with a substantially U-shaped vertical cross-section in the longitudinal direction with a bottom wall 3a and two side walls 3b, 3b. Locking parts 5, 10 are formed in both side walls 2b, 2b of the upper part 2 and in both side walls 3b, 3b of the lower part 3 respectively for locking together the walls, and the looking parts 5, 10 are locked together to temporarily look the upper part 2 and the lower part 3 together while the parts are integrated by brazing.

A method of efficiently producing a thick-walled small diameter pipe having a smooth flawless inner peripheral surface, which can be suitably used for a fuel injection pipe for diesel engines, is provided. In producing a thick-walled small diameter pipe by applying a plurality of times of stretching to a seamless raw pipe, the method comprises the steps of cutting the work pipe into lengths for which the product size is taken into consideration, prior to the final stretching, applying cutting or grinding to the inner peripheral surface of such length, and effecting the final stretching by forging utilizing a pressing force provided by a press.

A polishing device includes a wafer holder (31) that holds a wafer (W) and that brings the held wafer (W) into contact with a polishing surface (22a); a polishing plate driver (24) or a head driver (34) that, when polishing the wafer (W), relatively rotates the wafer holder (31) with respect to the polishing surface (22a) to which a slurry (SL) is supplied; a polishing pressure applier (32) that applies polishing pressure to the wafer (W) by pressing the wafer (W) against the polishing surface (22a) via the wafer holder (31); and a controller (50) that, during polishing of the wafer (W), cyclically switches a state of the polishing pressure applied to the wafer (W) via the polishing pressure applier (32) between a high pressure state and a low pressure state in which the polishing pressure is lower than in the high pressure state.
摘要:
A tube bending system for bending a processing target tube that includes a metal tube and two flare nuts into a specific shape, with the tube bending system including a bending machine and a tube delivery unit. The tube delivery unit includes a shift-to-end mechanism that performs a shift-to-end manipulation on the processing target tube to move the two flare nuts to the end portion sides of the processing target tube such that one of the two flare nuts abuts one of the two ring-shaped projections and the other of the two flare nuts abuts the other of the two ring-shaped projections, and an inspection mechanism that utilizes the shift-to-end manipulation to detect an abnormality of the processing target tube that is to be bent in the bending machine.
摘要:
A pipe branch structure includes a main pipe, and plural branch couplings disposed one-to-one at plural branch positions set between both axial direction ends of the main pipe. A cross hole is formed at each of the branch positions of the main pipe. Each branch coupling includes a tubular section attached to an outer periphery of the main pipe, a branch section formed with a passage in communication with an inside of the tubular section and configured to connect to a branch pipe, and a seal member configured to seal between the main pipe and the tubular section. The tubular section is attached to the outer periphery of the main pipe in a state in which the cross hole and the passage in the branch section are in communication with each other.
