Lobed nut cap
A cap is disclosed having a collar portion with three or more contact regions arranged to contact the end of a fastener around which the collar portion is provided, the collar portion having a lobed shape in cross-section such that an outwardly projecting lobe extends between each neighbouring pair of contact regions. An advantage of this lobed arrangement is that the cap can tolerate relatively large manufacturing tolerances at the fastener end. The cap may be for fitting over a nut or fastener head, with the contact regions of the cap being arranged to contact corresponding contact regions on a cylindrical collar base portion of the nut or fastener head. The diameter of this cylindrical collar portion may not be well controlled, so that the manufacturing tolerance is high. The lobed shape of the cap base ensures that the contact regions will always provide a good frictional engagement with the nut, whether the cylindrical collar is undersized, oversized, or at its nominal diameter.
Variable nozzle unit, turbocharger, and method for manufacturing variable nozzle unit
A variable nozzle unit includes: a connection pin which includes a shaft; a support ring which is provided with a first through-hole; and a nozzle ring which is provided with a second through-hole, in which the shaft is inserted through the first through-hole and the second through-hole, one end of the shaft is provided with a flange portion having a diameter larger than that of the second through-hole and the other end of the shaft is provided with a head portion having a diameter larger than that of the first through-hole, the flange portion is in contact with the nozzle ring, and an elastic member that urges the support ring toward the nozzle ring is disposed between the head portion and the support ring.

ROTARY CAULKING DEVICE, METHOD OF MANUFACTURING HUB UNIT BEARING AND METHOD OF MANUFACTURING VEHICLE
A hub main body (13z) is supported by a support portion (18). At least one block (22) is engaged with a stationary flange (6) of an outer ring (2). As a support plate (21) rotates, the outer ring (2) rotates. A caulking portion (16) is formed by pressing a pressing die (20) on a cylindrical portion (31).

DEVICE AND METHOD OF APPLYING A SEALANT AROUND A STRUCTURAL ADHESIVE TO PREVENT CORROSION
A method of joining first and second vehicle components to make an assembly includes applying structural adhesive and mastic to the first component. The first and second component may be made of different metals, and are brought together and joined at an interface using a linkage. Thereafter, the structural adhesive and mastic are cured. The mastic seals an interior edge of the interface, which is located at an interior of the assembly. A dust sealer is applied and cured to seal the exterior edge of the interface, which is located at an exterior of the assembly. The method results in sealing of all the edges around the entire perimeter of the interface, thus inhibiting water intrusion into the interface and possible corrosion resulting therefrom.
Fixation device for securing a linear element to a workpiece
A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.

Methods for modeling tubing runs
A method of modeling layout of rigid tubing comprises securing a first component of a lockable adjustment assembly to an end A of a first rigid tube via a first releasable coupling assembly. The method also comprises securing a second component of the lockable adjustment assembly to an end C of a second rigid tube via a second releasable coupling assembly. Further, the method comprises moving the first component and the second component, loosely coupled with each other, relative to each other with only three degrees of freedom to position the first rigid tube and the second rigid tube in a selected orientation with respect to each other. The method also comprises, with the first rigid tube and the second rigid tube in the selected orientation relative to each other, locking the lockable adjustment assembly so that the first component and the second component have zero degrees of freedom relative to each other.
