A helmet manufacturing method involves: producing a shell and a protector, the shell having two opposing cheek-protecting portions, the protector having a jaw-protecting portion and a neck-protecting portion connected to the jaw-protecting portion; putting the shell and the protector in a die such that bottom edges of the cheek-protecting portions of the shell connect to a top edge of the neck-protecting portion of the protector; introducing a foam material into the die, apply heat and pressure to the foam material such that the foam material expands and binds to an inner side of the shell and an inner side of the protector; and taking a helmet finished product out of the die. Therefore, both the jaw-protecting portion of the integrally-formed protector and the helmet finished product are reinforced.

A member joining method includes: a placement process of arranging a first member and a second member inserted into the first member so that a gap surrounding the second member is provided between the first member and the second member; a filling process of filling a molten resin into the gap and applying pressure to the resin so as to cause at least one member of the first member or the second member to undergo elastic deformation; and a pressure maintaining process of maintaining the pressure until the resin that has been filled into the gap has cured.

An in-mold encapsulation and processes for its manufacture are disclosed, comprising two or more plastic molded parts and a coating, such that when the encapsulation is rotated 360° about an axis, the coating may be seen as applied to a portion of the outside surface of the molded parts at any degree about that axis. In embodiments, the molded parts comprise polycarbonate, and the coating composition comprises isocyanate reactive groups and a polyisocyanate. The encapsulation may comprise areas where the coating is not applied, even though only the coating and not any other adhesive or structure holds the plastic molded parts together.

In one embodiment, a method for fabricating a neurostimulation stimulation lead comprises: providing a plurality of ring components and hypotubes in a mold; placing an annular frame with multiple lumens over distal ends of the plurality of hypotubes to position a portion of each hypotube within a respective lumen of the annular frame; molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead, wherein the molding fills interstitial spaces between the plurality of ring components and hypotubes with insulative material; and forming segmented electrodes from the ring components after performing the molding.

A molded plastic article having a bonded plastic portion 6 bonding a first body and a second body together; a connecting plastic portion 8, formed by solidifying the molten plastic flowing out from the plastic channel, having one end connected to the bonding plastic portion 6; and a flow tab plastic portion 7 formed by solidifying the molten plastic, connected to the other end of the connecting plastic portion 8 connected to the other end portion of the 8. A portion of reduced diameter 7a is provided to the flow tab plastic portion 7 on the connecting plastic portion side.

In one embodiment, a method for fabricating a neurostimulation stimulation lead comprises: providing a plurality of ring components and hypotubes in a mold; placing an annular frame with multiple lumens over distal ends of the plurality of hypotubes to position a portion of each hypotube within a respective lumen of the annular frame; molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead, wherein the molding fills interstitial spaces between the plurality of ring components and hypotubes with insulative material; and forming segmented electrodes from the ring components after performing the molding.

A toilet seat includes: a bottom plate including an engaging part; a top plate including a sidewall part provided on the bottom plate and a seating part supported by the sidewall part; and a bonding member having an exposed surface exposed externally. The engaging part is provided at a position opposing the sidewall part and has a recessed shape recessed downward. The sidewall part includes a sidewall base, a first hanging part extending downward from the sidewall base and engaging the engaging part, and a second hanging part provided to be separated from the first hanging part at the sidewall base to provide a recess recessed upward between the first hanging part and the second hanging part, the second hanging part being disposed at a position not overlapping the bottom plate. A side surface of the engaging part faces away and also extends away from the second hanging part.

Manufacturing methods are described for a goggle having an outrigger system where each outrigger includes a first segment coupled to a second segment at a fixed joint. Portions of the first segment may interlock or join with complementary portions of the second segment, such as through interlocking shapes, a solid friction lock, or via co-molding. The joining portions of the first and second segments may include complementary shapes that interlock together to secure the first and second segments together. The second segment may be molded onto or around at least a portion of the first segment, or vice versa, to secure the first and second segments together.

A helmet includes a shell having a head-protecting portion and two opposing cheek-protecting portions, the two cheek-protecting portions extending downward, integrally from left and right ends of the head-protecting portion, respectively, a protector having a jaw-protecting portion and a neck-protecting portion, the neck-protecting portion extending backward, integrally from a back end of the jaw-protecting portion, wherein a top edge of the neck-protecting portion of the protector connects to bottom edges of the cheek-protecting portions of the shell, and a foam liner disposed on an inner side of the shell and on an inner side of the protector to couple the shell and the protector together. The helmet further comprises a support disposed within the protector and enclosed by the foam liner.

A method of forming at least one channel within a substrate includes coupling a fitting to a mold, and securing together the fitting and an insert via threads. A system includes a mold configured to form the substrate. The method also includes inserting a component into an opening of the fitting. Part of the component is disposed outside of the opening of the fitting, and the component is utilized to define the at least one channel within the substrate. The method further includes molding at least one material to the component and the insert to form the substrate. Furthermore, the method includes removing the fitting from the insert while the insert remains molded to the substrate.
