According to a method of the present invention for treating a terminal portion of an interior part for a vehicle, the terminal portion is stably maintained in a folded state by being welded firmly and deformation is constrained.

In a heating step, in a state where distal end edges of heat shield panels 30A and 30B are abutted against a boundary between a terminal portion 4 and an adjacent portion 5 of a peripheral edge portion 3 of an opening of a roof trim 1 for a sunroof, hot-air is provided toward a back surface of the terminal portion 4 from hot-air nozzles 40A and 40B, thereby softening the terminal portion 4 and melting the back surface of the terminal portion 4. In a folding-back step, the terminal portion 4 is folded back by pressing members 50A and 50B at the distal end edges of the heat shield panels 30A and 30B and then pressed against the adjacent portion 5, thereby welding the back surface of the terminal portion 4 to a back surface of the adjacent portion 5. A ventilation opening 32a is formed in the heat shield panel 30A disposed at a corner portion. In the heating step, a portion of the hot-air from the hot-air nozzle 40A is guided to the adjacent portion 5 through the ventilation opening 32a to heat the adjacent portion 5.

An expansion-molded article that can be firmly heat-fused with another member is provided. The expansion-molded article is one that may be heat-fused with another member, where the expansion-molded article includes at least one protrusion which is formed on at least one surface of the expansion-molded article including at least one surface is to be heat-fused with the another member. The at least one protrusion comprises at least two surfaces as viewed from above, and a boundary line between the at least two surfaces, where the at least one boundary line intersects a direction from an outside of the at least one protrusion toward a center of an apex of the at least one protrusion.

A package including at least one bumper having an elliptical shape that extends from a first end to a second end along a first plane and having a protrusion that extends from a first front along a second plane; and a first tray having a first cavity that extends from a second front along the second plane, wherein the first cavity includes at least one groove configured and dimensioned to receive the at least one bumper.

An article of manufacture comprises a strip that extends along and is centered on a virtual curvilinear path, comprising an arc, having an arc length and a radius. A ratio of the strip-width to the radius is greater than or equal to 0.003. The arc length is equal to or greater than a product of the radius and /64. Within each of discrete strip-regions of the strip, one of the unidirectional reinforcement fibers that is closest to the first longitudinal strip-edge is more buckled than another one of the unidirectional reinforcement fibers that is closest to the second longitudinal strip-edge. Ones of the unidirectional reinforcement fibers that are buckled are parallel to a smallest one of virtual surfaces, joining the first longitudinal strip-edge and the second longitudinal strip-edge.

An instrument panel unit (2) includes an instrument panel (3) and a decorative sheet (4). The instrument panel (3) includes a sticking portion (3a) and an exposed portion (3b). A plurality of insertion grooves 3c and insertion holes 3d are formed alternately at an end on a rear side of the sticking portion (3a), into which bent pieces (4a) formed at a rear end of the decorative sheet (4) are inserted. A groove front-surface (3g) forming the insertion groove (3c) of the instrument panel (3) is formed in a tapered shape such that a width between the groove front-surface and an opposing groove rear-surface (3h) gradually increases upwardly. The bent piece (4a) is formed to be thinner than the groove width at the upper part serving as the entrance part of the insertion groove (3c) and to be thicker than the groove width of a groove bottom-surface (3i).

A method for producing a centrifugal pump impeller having a base plate, which is a single piece with pump blades and a cover plate, which consists of a thermoplastic material, wherein contact areas are available, which are heated and melted by means of ultrasonic excitation and form a close bonded connection after cool-down. The objective of the invention is to ensure inherent stability with the individual parts and a simple and reliable pre-assembly as well as a fixed mechanical connection, wherein only a small amount of excitation energy is required, with a centrifugal pump impeller comprising a base plate and cover plate.

A 3D processing device configured to attach a decorative film on a surface of a 3D glass, the 3D processing device includes a decorative film pre-deformation unit and a attachment unit. The decorative film pre-deformation unit includes an upper mould and a lower mould opposite to the upper mould, wherein the upper mould engages the lower mould to press the decorative film and cause the decorative film to have a shape matching a surface of the 3D glass. The attachment unit defines a sealing chamber, and includes a mould and a gas bag within the sealing chamber, wherein the mould is configured to support the 3D glass. The present disclosure further provides a method thereof.

A method of repairing or reinforcing, or attaching an accessory part to a wind turbine blade includes: determining a criterion to be satisfied by a repair member including a reinforcing fiber and a UV curable resin, the criterion being an adhesion strength of the repair member relative to a base member of the wind turbine blade; determining a work condition including: dimensions of the repair member, the number of the layers of the reinforcing fiber in the repair member, and/or a fiber extension direction of the reinforcing fiber, based on a damage condition of a repair target portion of the wind turbine blade; placing the reinforcing fiber and UV curable resin on the repair target portion based on the determined work condition; and obtaining the repair member by curing the UV curable resin so that the adhesion strength of the repair member relative to the base member satisfies the criterion.

A vehicle lamp includes a lamp housing having an inner space and a welding surface, and a cover disposed adjacent to another vehicle lamp, and configured to cover the inner space and join to the lamp housing by laser welding. The cover includes a design surface in which an outer surface of an outer peripheral portion is formed as a curved surface and a welding leg that protrudes from a portion near the outer peripheral portion in the design surface. An annular portion on an inner peripheral side of the curved surface on an outer surface of the design surface is formed as a laser light incident surface. The curved surface is positioned on an outer peripheral side from an intersection point of a virtual line and the outer surface of the design.

A first thermoplastic component and a second thermoplastic component including a first joint portion and a second joint portion, respectively, are provided. A least a portion of a surface area of each of the first and second joint portions include a respective first and second mating surface. The first and second mating surfaces of the respective first and second joint portions are positioned in contact with one another. The first and second joint portions are fusion joined. Fusion joining the first and second joint portions forms a fused unitary portion of the first and second thermoplastic components.
