Each of the first lens surface and the second lens surface is one of a multi-aperture lens surface, a lenticular lens surface, an aspheric lens surface, a flat lens surface and a freeform lens surface.

A laser welding member that has a high laser transmittance at a welding region and exhibits an excellent laser welding processability, and a molded article obtained by laser welding using this laser welding member. The laser welding member is obtained by injection molding of a thermoplastic polyester resin material, wherein a region to be laser welded in the member is at a location separated by a distance of at least 15 mm from a gate of an injection molding mold and has at least 30% of a light transmittance of laser light with a wavelength of 940 nm.

A connector (1) includes a plurality of connector terminals (3), core resin portions (2A), (2B), nuts (4) and an outer resin portion (5). A plurality of the nuts (4) are arranged to face a nut facing surface (21A) of the core resin portion (2A). The outer resin portion (5) covers the core resin portions (2A), (2B) and the nuts (4) with exposed surfaces (25) of the core resin portions (2A), (2B) and outer end surfaces (41) of the nuts (4) exposed. Injection marks (51) during molding of the outer resin portion (5) are formed on a surface of a part of the outer resin portion (5) covering an opposite side surface (22B) located on a side opposite to the nut facing surface (21A).

A biochip for the integration of all steps in a complex process from the insertion of a sample to the generation of a result, performed without operator intervention includes microfluidic and macrofluidic features that are acted on by instrument subsystems in a series of scripted processing steps. Methods for fabricating these complex biochips of high feature density by injection molding are also provided.

The invention concerns a plastic closure part (10) which can be fixed to a container or a further closure part to be fixed to the container, comprising a tubular discharge portion (3) whose cross-section is closed by a membrane (7) which has a tear line (8) extending peripherally over more than 180 along its outer edge and a corresponding method for the production of such a closure. In order to develop a closure part having the features set forth in the opening part of this specification and a method for the production thereof to the effect that the problems occurring upon injection moulding due to narrow flow passages are eliminated it is provided according to the invention that the tear line (8) is formed by a cut introduced into the material of the membrane (7) with a cutting or punching tool.

A wheel for a vehicle in which the wheel comprises a non-pneumatic tire that may be designed for robust, long-lasting performance in challenging conditions, including by using a process to make the non-pneumatic tire that may be specified such that a material of the non-pneumatic tire retains most or all of its inherent capabilities. For example, an annular beam and an annular support of the non-pneumatic tire may be injection molded together from elastomeric material flowing first where at least part of the annular beam is before flowing where at least part of the annular support is (e.g., using a molding apparatus that comprises a mold including a mold cavity and outer gating to inject thermoplastic material at an outer part of the mold into the mold cavity adjacent to where the annular beam is to be formed).

A manufacturing method of a semiconductor device, includes: (a) preparing a lead frame having: a first tie bar extending in a first direction in plan view so as to couple a plurality of first leads to one another; a second tie bar extending in the first direction in plan view so as to couple a plurality of second leads to one another; a coupling portion coupled to the first tie bar and the second tie bar; a first chip mounting portion arranged between the first tie bar and the second tie bar in plan view; and a second chip mounting portion arranged between the first chip mounting portion and the second tie bar in plan view; and (b) after the (a), mounting a first semiconductor chip on the first chip mounting portion and mounting a second semiconductor chip on the second chip mounting portion.

A method of making a two-component piston, the two-component piston including a piston cover as the first component and a piston body as the second component. The piston cover is arranged adjacent to the piston body and is configured to be moved relative to the piston body.

A protective cover includes: a synthetic resin disc part having formed therein a separation wall which is thinner than other parts of the disc part and separates a magnetic encoder and a magnetic sensor from each other; and a synthetic resin sensor holder part protruding inward from the disc part. A gate mark caused by the injection molding is present n an outer peripheral surface of the disc part or an outer peripheral surface of a cylindrical part continuous with the disc part, in the radially outer side of the separation wall. Since the gate is at the radially outer side, of the separation wall, which is near the separation wall, no charging end weld is generated on the separation wall when a molten synthetic resin material is injected from the gate into the cavity of the injection mold die and solidified in an injection molding step.
