A method for producing a light module for a lighting device of a motor vehicle, wherein the module comprises a support component and a light-outcoupling component. According to the invention, a connection element for establishing a retaining connection between the support component and the light-outcoupling component is molded at least onto the support component by means of an injection molding process.

Provided is a decorative sheet in which a graphic is less deteriorated even after injection molding. First and second graphic layers contain a plurality of interference pigments that emit respective interference lights having respective colors in a first direction in first and second binders to exhibit first and second mixed colors. An optical functional layer changes a reflectance property of light. The first and second graphic layers represent a graphic visually recognizable from a front surface of a decorative sheet and allow visually recognizing an image displayed on a back surface from the front surface. The optical functional layer increases at least one of ratios of an amount of visible light representing the graphic and an amount of visible light representing the image that transmits through the first and second graphic layers to an amount of visible light reflected by and visible on the front surface.

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 gear manufacturing method, the gear including an annular gear portion including teeth on an outer periphery, an annular support portion provided on an inner peripheral surface of the gear portion and supporting the gear portion, and a core portion provided inside the support portion, the method includes: a support portion molding step of molding the support portion by disposing the gear portion and the core portion in an annular mold and filling a resin between the gear portion and the core portion; and a support portion cooling step of cooling the support portion molded in the support portion molding step, a radial gap between the teeth of the gear portion and the mold before the support portion molding step is set to be smaller than a radial shrinkage amount of the support portion in the support portion cooling step.

The resin molded article is molded by using an electrode sheet as an insert in a state where one surface of the electrode sheet is closely attached to an inner surface which serves as the inner side of the operation surface. The electrode sheet is formed by using, as a base material, a thermoplastic synthetic resin sheet which outputs an electrical signal according to the amount of change of electrostatic capacitance generated by a contact operation with respect to the operation surface. At least a whole or a part of the inner surface is formed in a three-dimensionally curved surface, and a passage is formed in the electrode sheet so as to allow a molten resin following in through a gate formed in a die which comes into contact with the other surface of the electrode sheet during molding to pass toward one surface side of the electrode sheet.

Provided is a decorative sheet in which a graphic is less deteriorated even after injection molding. First and second graphic layers contain a plurality of interference pigments that emit respective interference lights having respective colors in a first direction in first and second binders to exhibit first and second mixed colors. An optical functional layer changes a reflectance property of light. The first and second graphic layers represent a graphic visually recognizable from a front surface of a decorative sheet and allow visually recognizing an image displayed on a back surface from the front surface. The optical functional layer increases at least one of ratios of an amount of visible light representing the graphic and an amount of visible light representing the image that transmits through the first and second graphic layers to an amount of visible light reflected by and visible on the front surface.

A tool for installing a liquid shim material into a clearance formed between an assembly first and second component includes a body having a first end and a second end. The first end includes a planar surface and the second end includes a first surface and a second surface arranged at an angle to the first end and to one another. At least one hole is formed in the body. The at least one hole extends from the first end to the second end and is configured to provide a passageway through the body. The tool is arranged adjacent the assembled first and second component such that the passageway formed by the at least one hole is arranged in fluid communication with the clearance.

A tubing system with a coupler join positioned between and joining tubing segments. The coupler join is formed to reduce dead legs and hold up volumes within, and/or to reduce materials used to form, and/or to simplify the manufacturing process of the tubing system. The coupler join may be sized, shaped, configured, and/or dimensioned to join tubing segments, such as pre-formed tubing segments, in a streamlined configuration, such as to substantially correspond with the outer and inner diameters of the tubing segments. The tubing system and coupler join may be formed with a mold configured to form a coupler join securely coupling spaced apart ends of tubing segments to be joined together in a configuration which reduces dead legs and hold up volumes within the resulting tubing system.

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.

In a bus bar unit in which a plurality of bus bars are formed by insert molding and arranged in an axial direction of a stator, each bus bar includes: a main body portion extending in a circumferential direction of the stator; a through hole formed in the main body portion, into which a support pin for supporting the main body portion of another bus bar is inserted in the axial direction of the stator during insert molding; and a projecting portion provided on a side portion of the main body portion in alignment with the through hole so as to increase a sectional area of the main body portion.
