An inflation device includes a balloon and a shaft coupled to one another via an overmold that includes a shut-off ridge. The shaft is in pressure communication with the balloon. Therefore, when fluid pressure is increased in the shaft the balloon may inflate. The use of shut-offs to form the overmold including shaping the shut-off ridge should result in an overmold with no flash and few or no bubbles within its structure.

The present invention relates to a process and apparatus for the preparation of a bonded substrate. More particularly, the present invention relates to a PDMS bonding apparatus. More specifically, the present invention relates to a PDMS bonding apparatus which uses plasma to bond PDMS to a substrate.

The present invention discloses a PDMS bonding apparatus and process for using said apparatus, the apparatus comprising: a process chamber (100) forming a sealed processing space (S) for bonding of PDMS (polydimethylsiloxane); a first support (200) installed in the process chamber (100) and which supports the PDMS (1); a second support (300) installed in the process chamber (100) opposing the first support (200) and which supports a bonding object (2) which is bonded to the PDMS (1); a gas injection unit (400) which ejects process gas between the first support (200) and the second support (300), and; a plasma generator (500) which creates a plasma atmosphere within the process chamber (100).

A 3D printing system includes a tank containing a liquid photopolymer resin. A textured surface is disposed in the tank. The textured surface is configured such that light passes through therethrough and into the liquid polymer resin. A layer of an inert material is disposed on the textured surface.

The present invention relates to a composite component including a metal component having a substantially cylindrical shape or a substantially annular shape, and a ring-shaped bonded magnet disposed on the outer periphery of the metal component, the ring-shaped bonded magnet containing a thermoplastic resin, magnetic particles, and rubber particles.

The present invention relates to multilayer films used to protect a surface, in particular, to such films used to protect surfaces of articles e.g., mobile electronics display protections, smartphones, tablets), industrial touch screens (e.g. machine interfaces), UV stable surfaces and glass protections for machine housings and cockpits (e.g. caterpillars, dumpers), etc.), and, more particularly, to such a multilayer protective film backed by a silicone-based pressure sensitive adhesive (PSA) and having either an aliphatic polyurethane layer or an aliphatic thermoplastic polyurethane layer on top of an aliphatic thermoplastic polyurethane layer, where the two aliphatic polyurethane layers have different physical and/or chemical properties. The present invention also relates to an article that is protected by the multilayer film as well as a method for making the multilayer protective film.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.

An ear tip for use with an earphone is filled with a UV-curable polymer or other material that hardens when energy is applied, fitted to a user's ear, and exposed to UV light or other appropriate energy, curing or otherwise hardening the material and forming a custom-fit ear tip.

The present disclosure relates to a composite article that may include a plastic component, and a silicone component bonded the plastic component. The plastic component and the silicone component may be bonded at an intersecting region between a first surface of the plastic component and a first surface of the silicone component. The intersecting region may include at least one of an acetone content of not greater than about 0.2 ppm, an MEK content of not greater than about 0.2 ppm, or a trimethylsilanol content of not greater than about 0.2 ppm.

A multi-layered sheet includes a substrate sheet and a thermally curable layer that is disposed on a surface of the substrate sheet and can be disposed on at least a part of a surface of a mold resin, wherein the thermally curable layer is an uppermost layer of the multi-layered sheet, the thermally curable layer includes a product of active energy ray-curable resin cured or half-cured by active energy ray, and the thermally curable layer has: a thermally reactive group that can react and thermally cure with a material component of the mold resin; and a polysiloxane chain.

A method of manufacturing a plurality of optical elements includes providing a first wafer (200) having lower alignment features (192) arranged on a first surface of the substrate, providing a second wafer (201) comprising, on a replication side, a plurality of replication sections, each replication section defining a surface structure of one of the optical elements, the second wafer (201) further comprising upper alignment features (194) protruding, on the replication side, further than an outermost feature of the replication sections, depositing liquid droplets (196) on the first side of the first wafer (200), and bringing the second wafer (201) and the first side of the first wafer (200) together, with liquid droplets (196) between the first wafer (200) and the second wafer (201), the upper alignment features (194) contacting the liquid droplets (196) on the lower alignment features (192) on the first side of the first wafer (200), and thereby causing the second wafer (201) to align with the first wafer (200) by capillary action.
