A propeller (1) includes a hub (2), blades (3), and a shell (4) having two flanks (41, 42) connected by an elbow, the blades (3) extending from the hub (2) to the shell (4). The thickness (e1, e2) of at least one part of at least one of the flanks (41, 42) of the shell (4) is reduced towards the free end of the flank.

A molding method for a synthetic resin molding that includes a molding body, a bent portion, and a flange. The bent portion and the flange are continuous in a longitudinal direction of the side edge. The flange includes a wide portion and a narrow portion. The molding method for the synthetic resin molding includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction, performing injection molding using a colored resin material containing a luster agent kneaded in the material, and forming a protrusion along the side edge in the longitudinal direction at a back of a boundary portion between the flange and the molding body to reduce interference of flow of the molten resin from the flange toward the molding body during the injection molding.

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 lens holder including a base, a gate mark and a tubular portion is provided. The base includes a plurality of sidewalls, and any two adjacent sidewalls are connected to each other to form an outer edge. A turning corner is formed between every two adjacent sidewalls, and the base includes a chamfer located at a turning corner. The gate mark is disposed at the chamfer. The tubular portion is connected to the base, and the tubular portion extends along the direction away from the base. Besides, a portable electronic device and a manufacturing method of the lens holder are also provided.

A prism (1090) is configured from a dielectric medium and is used in analysis using surface plasmons. The prism (1090) is provided with an incidence surface (1170) on which excitation light from outside is incident, a reflection surface (1172) on which excitation light having entered the incidence surface (1170) is reflected, an emission surface (1174) from which excitation light reflected by the reflection surface (1172) is emitted, and an opposing surface (1175) opposing the reflection surface (1172). A gold film (1092) is formed on the reflection surface (1172). The opposing surface (1175) has a sink-mark surface (1200), and the sink-mark surface (1200) is a transparent surface.

A net-shaped composite plenum housing body for a differential assembly having a pump is disclosed. The plenum housing body can include a low pressure inlet and a high pressure outlet configured to receive a control valve. The plenum housing body can also define a fluid inlet channel in fluid communication with the low pressure inlet via a first internal port and can be configured to be in fluid communication with an inlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also define a fluid outlet channel in fluid communication with the high pressure outlet via a second internal port and can be configured to be in fluid communication with an outlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also be formed as a net-shape fiber reinforced plastic material including chopped fibers, for example, chopped fiberglass fibers, and an epoxy resin.

Disclosed is a mold assembly comprising: a cavity forming an inner space to be filled with resin containing metallic particles, and having a protruding part corresponding to a hole of a molded object; a first gate disposed at any one side of the cavity so as to inject the resin into the inner space; and a second gate disposed at another side of the cavity, and injecting the resin, which flows in a second direction intersecting with a first direction, into the inner space so as to change the arrangement of the metallic particles such that a weld line, formed according to the orientation of metallic particle in the first direction, is blurred in an area at which the flow of the resin is separated by the protruding part and then comes back together.

The present invention relates to a method for the production of injection-moulded, reinforced moulded parts, the fibre orientation of which is specifically adjusted on a local basis. Via suitable, dynamically controlled supplementary heating in the wall of the injection mould which is used (variotherm heatable channel), a local cavity region is hereby heated at the time of injection to a temperature in the region of or above the solidification temperature (in any case above the crystallisation temperature in the case of partially crystalline plastic materials or above the glass transition temperature in the case of amorphous plastic materials) of the polymer (plastic material moulding compound).

An injection molded article obtained by injection molding a thermoplastic resin composition comprising 100 parts by mass of a thermoplastic resin and 50 parts by mass or less of at least one of a filler and a colored metallic pigment, wherein at least one weld exists, and a long diameter of 95% by mass or more of the filler existing within a cross-sectional depth of 50 μm or less from a surface of the weld is parallel to the surface of the weld.

Provided is an injection molding die capable of adjusting a size of a support member, preventing bending of a mold, and preventing occurrence of burrs without removing the mold and making the support member again. The present invention provides an injection molding die including a fixed mold and a movable mold that face each other, the fixed mold and the movable mold being clamped to form a cavity for molding a molded product, the injection molding die further including at least one support member that is provided to abut on a surface opposite to a surface on which the cavity is formed in either or both of the fixed mold and the movable mold, the at least one support member being a stretchable support member in a direction of the cavity.
