Abstract: Performed are an accommodation step of accommodating a pair of conductive members in a die, a sealing step of injecting a resin to seal the conductive members, and an extraction step of extracting a conductive member module. In the sealing step, the conductive members are sealed while a force is applied by the resin injected into the die to the individual conductive members in directions away from each other, and the individual conductive members are supported by support members disposed outside.

Abstract: A second mold is divided into a recess-side mold portion, which includes a recess, and a remaining mold portion in a sliding direction of a movable pin, while a size of a gap between the recess-side mold portion and the remaining mold portion is adjustable. The second mold is configured to execute a first-mold-closing operation for contacting the recess-side mold portion to the first mold and thereafter a second-mold-closing operation for contacting the remaining mold portion to the recess-side mold portion. A distal end portion of the movable pin is configured to be placed into a non-contacting state, in which the distal end portion of the movable pin is not in contact with the workpiece, at a time of executing the first-mold-closing operation. The distal end portion of the movable pin is configured to contact the portion of the workpiece at a time of executing the second-mold-closing operation.

Abstract: In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.

Abstract: A molding die has a lower holder, an intermediate holder, an upper holder, a lock member, an upper link bar, a lower link bar, a restriction member, and a drive part. A movement of the lock member in a molding die opening direction or a molding die closing direction is restricted by the intermediate holder. The upper link bar has a first retaining groove in which the lock member fits when being located at a molding die closing position. The lower link bar has a second retaining groove in which the lock member fits and a release portion that enables the lock member to be released from the first retaining groove. The restriction member is movable between a restriction position that prevents the lock member from fitting in the second retaining groove and a free position that enables the lock member to fit in the second retaining groove.

Abstract: A fuel supply device includes a flange, a pump unit, a supporting pillar, and a boss. The flange is attached to an opening portion of a fuel tank. The supporting pillar supports a sub tank such that the sub tank is positioned closer to and away from the flange. The boss is fixed at the flange and an end of the supporting pillar is inserted into the boss. The boss is made of a material different from that of the flange. The boss includes a stress concentration portion that is preferentially broken when a force equal to or greater than a predetermined value is applied to an end portion of the supporting pillar in an axis perpendicular direction.

Abstract: A method includes a first molding process and a second molding process performed repeatedly. The first molding process includes injecting resin into a first pair of molds, in which a first pair of divided pieces is formed and which is fitted together without an inner mold, to couple the first pair of divided pieces to form a first hollow article at an injection station. The second molding process includes (i) injecting resin into a third pair of molds, which is fitted together with one inner mold interposed therebetween, to mold a third pair of divided pieces at the injection station, (ii) taking out the first hollow article from the first pair of molds at a removing station, and (iii) removing another inner mold from a second pair of molds while leaving a second pair of divided pieces between the second pair of molds at the setup station.

Abstract: A resin member is formed from a resin material containing filler and an insulating base polymer as a main component. The resin member includes an alignment layer close to a surface of the resin member. The alignment layer includes the filler aligned in the surface direction and the base polymer filling the space between pieces of the filler. The alignment layer includes a carbonized portion that is carbonized matter of the base polymer, contains graphite, and provides electrical conductivity and thermal conductivity.

Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. Other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.
