A gas sensor includes, in a single housing section, a substrate mounting surface 31 mounted with a substrate including a light emitter and a light receiver and a mirror section including plural reflectors. Then, in the housing section, all of the plural reflectors are integrally molded on an inner surface of the housing section to multiple reflect light emitted from the light emitter and cause the light to enter the light receiver in an opposing direction of one side and the other side in an extension direction of the substrate mounting surface.

A method of producing a product utilizing a liner. The method comprises securing, at an injection molding manufacturing system, a liner to a first half of a mold. The method further comprises clamping, at an injection molding manufacturing system, the first half of the mold to a second half of the mold, wherein clamping the first half of the mold to a second half of the mold generates a total mold. The method further comprises generating, at an injection molding manufacturing system, a formed product, wherein generating the formed product further comprises filling an opening of the total mold with a molten material. The method further comprises ejecting, at an injection molding manufacturing system, the formed product, and the liner from a completed first half of the mold and releasing, at an injection molding manufacturing system, the formed product from the liner.

Provided is a mold part which does not generate periodic irregularities (scale pattern) which appear in the direction orthogonal to the drawing direction (MD) of the mold part having a surface which slides parallel to a molded article when the molded article is removed from the mold after injection molding during injection molding of a thermoplastic resin (in particular, a thermoplastic fluoropolymer), an injection molding method using the same, and a molded article in which periodic irregularities (scale pattern) (which appear in the direction orthogonal to the drawing direction (MD) of the mold part) do not appear. The mold part is used for injection molding of a thermoplastic resin, and includes a surface which slides substantially parallel to a molded article when the molded article is removed from the mold after injection molding, wherein the average tilt angle in the sliding direction (MD) is 1.5° or higher.

It is an object of the present invention to provide improved methods and compositions for manufacture and use of lateral flow test devices. In particular, the present invention provides a molding method which provides one or more features in the housing base configured to retain the test strip within the base. These features are provided as undercuts in the housing base. The test strip is configured as a bibulous lateral flow material disposed on a substantially non-compressible base layer, and the base layer is positioned within the undercut in order to retain the test strip in the housing base. Optionally, one or more features in the housing base which create the undercut are configured to engage the bibulous lateral flow material by compression and/or friction, thereby increasing the ability of the base to maintaining the test strip in its proper position within the device.

In an injection molding mold, a cavity to shape an impeller is formed on a cavity piece. The cavity piece includes an inner piece portion on which the cavity is formed, and a support piece portion turnably supporting the inner piece portion and movably mounted on a fixed-side mold. This cavity piece is moved to a first mold separating position together with a movable-side mold. The inner piece portion is formed such that a spiral pattern groove to shape a plurality of spiral pattern vanes of the impeller constitutes a part of the cavity. When the movable-side mold separates from the cavity piece at the first mold separating position, the impeller moves integrally with the movable-side mold and separates from the inner piece portion while turning the inner piece portion such that the vane slides and moves inside the spiral pattern groove of the inner piece portion.
