A tubular body formed by joining two semi-tubular portions that are divided in radial direction, the tubular body having a connection flange portion provided with a bolt hole on at least one end portion. The two semi-tubular portions have joint projection portions at both edge portions in circumferential direction, the joint projection portions projecting in radial direction and extending in axial direction, and each joint projection portion of the semi-tubular portions on at least one of both sides in circumferential direction is configured to be bent so as to deviate from a virtual division face passing a central axis in such a manner that a joint portion formed by abutting the joint projection portions does not interfere with a tool for fastening a bolt inserted into the bolt hole in a predetermined area in the vicinity of the bolt hole of the connection flange portion.

A display protector attachment apparatus for a foldable electronic device according to the present disclosure includes: a frame unit including a frame-first end member at one end and a frame-second end member at another end and configured to support and accommodate the foldable electronic device between the frame-first end member and the frame-second end member; and an inclination-forming fixing unit connected to the frame-second end member and configured to align a protector film assembly to be arranged inclinedly with respect to the foldable display unit of the foldable electronic device by varying mounting heights for both ends of the protector film assembly including a display protector that is to be attached to the foldable electronic device.

A centrifugal fan assembly for improving flow of air through a heat exchanger. The fan assembly comprises a first subassembly comprising a first impeller flange and a second subassembly comprising a second impeller flange. Any of the first and second impeller flanges comprise a plurality of integrally formed impeller blades. The impeller blades and the first and second impeller flanges constitute an impeller. At least one impeller blade arranged on one of the two impeller flanges comprises at least one tab arranged to mate with a corresponding inlet cone arranged on the other of the two impeller flanges. The least one tab is arranged to be deformed when in a mating position with the corresponding inlet cone, thereby securing the two subassemblies together.

The invention relates to a method for assembling a first and a second part of a lighting device for a vehicle by mirror welding, including a step of supplying the parts wherein each part comprises, in the interface area thereof for contact with the other part, a weld bead intended to come into contact against the weld bead of the other part during the mirror welding, the weld bead of at least one of the parts is provided with a plurality of expander ribs (N) spread out along the weld bead, in such a way as to locally expand the width of the weld bead.

Wafers are aligned with one another by reference to features formed on or in each wafer. A method includes forming a first pivot-notch, a first stop-notch, and a first bias-notch in a first wafer by reference to first features formed on or in the first wafer. Also formed is a second pivot-notch, a second stop-notch, and a second bias-notch in a second wafer by reference to second features formed on or in the second wafer. A first wafer is mounted in an aligning device, wherein a two-contact element enters into the first pivot-notch, and a single-contact element enters the first stop-notch. The second wafer is mounted in the aligning device, wherein the two-contact element enters into the second pivot-notch, and the single-contact element enters the second stop-notch. A biasing force is exerted onto surfaces of the first and second bias-notches to align the first features with the second features.

A method is disclosed that includes removing an adhesive layer from a lower housing of a monitoring device; aligning the monitoring device with an opening of an adhesive applicator; coupling an uppermost adhesive layer that is positioned within the adhesive applicator with the lower housing; and removing the monitoring device from the opening of the adhesive applicator. A shape of the lower housing of the monitor corresponds to the shape of the opening of the adhesive applicator; and aligning the monitoring device with the opening of the adhesive applicator comprises matching the orientation of the lower housing to the orientation of the opening in the adhesive applicator. The method also includes the monitoring device selectively entering a battery preservation mode.

Butt welding machine (2) adjusting the ends of plastic pipes and welding them to each other, which comprises a cutter (1) having a driving element (16) for moving the trimmer (13) by being driven, at least one movable claw (24, 32, 33) moving depending on a connector to hold pipes which are positioned, a motor (21) which does not have direct connection with the cutter (1) and transfers power to the cutter (1) and to the movable claw (24, 32, 33) via one connector for each, a drive gear unit (22) which provides driving energy from one point to the cutter (1) and the movable claw (24, 32, 33) which wherein the cutter (1) and the movable claw (24, 32, 33) needs to be had two different driving motions performed via two different connectors, a drive gear unit (22) providing driving energy to the movable claw (24, 32, 33) from one point.
