A method for making teat unit including providing a support body and a securing part, the support body including a plurality of recesses, forming a teat by overmolding the teat over the support body and over the recesses of the support body so that the teat covers the recesses, and overmolding the teat over an upper edge of the securing part, thereby forming a connection between the securing part and the support body which connects the securing part to the support body. In another method, the support body and the securing part are already one single piece and the teat is overmolded at least over the support body.

A sealing method for sealing an opening of a metallic molded body with a resin molded body, the metallic molded body having a cavity therein and an opening connected to the cavity, includes a step of irradiating laser light onto a joining surface on a periphery of the opening of the metallic molded body in an energy density of 1 MW/cm.sup.2 or more and at an irradiation rate of 2000 mm/sec or more to roughen the surface, and a step of placing, in a mold, a portion including the joining surface of the metallic molded body roughened in the preceding step and sealing the opening with a resin molded body formed by injection molding or compression molding of a resin.

A worm gear for a worm gear system of a motor vehicle steering device may include a hub, a support element, and a gear rim. The support element may be a support ring that by means of an injection-molding method is injected between the gear rim and the hub. The support ring may connect in a form-fitting manner the hub and the gear rim. The gear rim and the support element may configure a multiplicity of teeth. The support element may have support webs that penetrate the gear rim such that radially outward pointing end sides of the support webs are exposed.

A method of coating a field joint, pipe sections for forming a coated field joint, and a coated field joint formed thereby. First and second angular cut backs are provided in the parent coating of each pipe section. The first angular cut back is at an angle of about 30°+−0.5° relative to the longitudinal axis of the field joint, and the second angular cut back is positioned further from the field joint than the first angular cut back. The first and second angular cut backs result in the parent coating having a stepped profile, a step in the stepped profile between the first and second angular cut backs, the step is substantially parallel to the longitudinal axis of the field joint and is often substantially free of indentations. The field joint coating may be injection moulded to have an upstand that is less than or equal to about 5 mm.

A method of coating a field joint, pipe sections for forming a coated field joint, and a coated field joint formed thereby. First and second angular cut backs are provided in the parent coating of each pipe section. The first angular cut back is at an angle of about 30°±5° relative to the longitudinal axis of the field joint, and the second angular cut back is positioned further from the field joint than the first angular cut back. The first and second angular cut backs result in the parent coating having a stepped profile, a step in the stepped profile between the first and second angular cut backs, the is substantially parallel to the longitudinal axis of the field joint and is free of indentations. The field joint coating is injection moulded to have an upstand that is less than or equal to about 5 mm.

A method for forming a seal boot includes forming a stack of discrete, non-intertwined layers by layering a sheet of elastomeric material with a fabric; rolling the stack to form a tube; installing the tube within a mold; closing the mold; and heating the mold and the installed tube.

A toothed pulley includes a cylindrical metallic core and a resin portion including teeth. The metallic core has, at one end thereof in the axial direction, an outward flange projecting outward in the radial direction. The outward flange has a radially outer peripheral surface that is a rotation prevention shape having a plurality of parts displaced inward in the radial direction from a cylindrical surface of the radially outer peripheral surface. The radially outer peripheral surface of the outward flange is covered by the resin portion.

A method of manufacturing a damping device, notably for a steering tie rod, the said device comprising a rod which extends along a main axis and which is intended to be connected to a first mechanical component, a securing portion which surrounds the said rod and which is intended to be connected to a second mechanical component, and a sleeve made of elastomeric material which is arranged between the rod and the fixing bushing so as, through elastic deformation thereof, to allow at least axial movement of the fixing bushing with respect to the rod, in which method the fixing bushing is offset axially with respect to the rod to force the elastic deformation of the sleeve and the introduction of a corresponding preload, then the sleeve is locked so as to keep it, when the device is at rest, in a state of permanent axial elastic deformation and preload.

A vehicle window glass includes a glass body provided with a through hole and an insert which is a hollow columnar body and at least one end of which is an open end. The insert is fixed in the through hole of the glass body. It is possible to obtain direct connection between the vehicle window glass and the large-size irregular decoration part with the cooperation of the through hole on the glass body and the insert in the through hole. This connection ensures positioning accuracy and fixing reliability and can be widely applied to various occasions.

A method of forming a fin configured for use with a water sports board. The method includes providing a mold having a mold cavity and first and second insert pre-preg sheets each including structural strands respectively bonded by first and second resin materials. The method further includes placing the insert pre-preg sheets within the mold cavity. The method further includes injecting a third resin material under pressure into the mold cavity between the first insert pre-preg sheet and the second insert pre-preg sheet to urge the first insert pre-preg sheet and the second insert pre-preg sheet away from each other and towards respective ones of the pair of mold cavity faces, and dispose the third resin material between the first insert pre-preg sheet and the second insert pre-preg sheet to space at least a portion of the first insert pre-preg sheet from the second insert pre-preg sheet.
