A metallic extruded profile has two parallel skins interconnected by a set of at least two webs running between extrusion edges of the profile and snap-fit features on joining edges permitting two instances of the profile to snap fit together along the joining edges, where a first web that is closest to snap-fit features of a first joining edge, is a curved web viewed from the extrusion edges. The curvature allows for both the curved web and skins to participate in snap-fit deformation, allowing for the deformation to be distributed over a large area, for a stiffer snap fit, and reduced plastic deformation.

A rotor comprising a shaft having splines with flanks thereon; a lamination disposed on the shaft and configured to engage at least one flank less than all flanks of all of the splines. A method for making a rotor comprising configuring a lamination with an opening for a shaft having splines thereon, the lamination having a recess that provides a clearance fit over a flank of a spline; press fitting the shaft into the lamination while maintaining clearance over the flank.

The diaphragm boss is fixed such that the shaft part and the enlarged-diameter part are exposed upwardly. The diaphragm member is held with an air suction force by a robot arm apparatus having an air suction part such that the small-diameter concave part and the large-diameter concave part are exposed downwardly. By controlling the robot arm apparatus, the diaphragm member is brought into contact with the diaphragm boss while tilting an axis of the diaphragm member with respect to an axis of the diaphragm boss. By controlling the robot arm apparatus, the small-diameter concave part and/or the large-diameter concave part of the diaphragm member are pressed against the diaphragm boss while rotating the diaphragm member around the axis of he diaphragm boss, so that the enlarged-diameter part is fitted into the large-diameter concave part and the shaft part is fitted into the small-diameter concave part.

An apparatus and method for pressing articles on components of a vehicle assembly is provided. The apparatus includes a support fixture, a driving mechanism coupled to the support fixture, and a sensor coupled to the support fixture. The apparatus detects a component that includes a receiving section and controls the sensor to determine a height of the receiving section with respect to a datum of the component, based on the detection. The apparatus computes an offset distance with respect to the determined height and actuates the driving mechanism based on the offset distance. Based on the actuation, the driving mechanism moves an actuator to a first position in proximity of the receiving section. The driving mechanism further actuates to displace the actuator from the first position to a second position, which causes the actuator to apply a force on an article, causing the article to mate with the receiving section.

[Problem] To provide a fuel nozzle for a gas turbine combustor, offering favorable durability and strength reliability. [Solving Means] A method for manufacturing a fuel nozzle for a gas turbine combustor, the method comprising: (a) fitting a fuel nozzle having an internal through hole into a through hole or a recess provided in a base plate; (b) bonding, by a fusion joint or a brazing joint, the fuel nozzle to the base plate in an interface therebetween on a surface of the base plate; and (c) following the step of (b), subjecting the fuel nozzle and the base plate to a pressure bonding process to thereby pressure bond the fuel nozzle and the base plate in the interface therebetween.
