Elongated device to seal a substrate
12349748 · 2025-07-08 ·

An elongated device to seal an edge of a substrate has an elongated flexible linear form capable of rolling, akin to a tape. The tape has its own substrate encapsulated by a polyurethane coating. Upon application of heat, the tape welds to a base layer of a fabric, such as nylon. The tape continuously merges into the base and thus prevents intrusion of fluids and gasses through any stitching or other apertures of the base, including any pathogens, microbes, and viruses in the fluids and gasses. The tape resists over forty washings of the conjoined base part of a garment made from the fabric. The tape has proportions that promote a tight seal of the base and comfortable feel to the skin of a wearer of a garment having the tape upon the fabric.

Hot melt apparatus and method of use

In various embodiments, a hot melt device comprising a heating device that is automatically or manually triggered is configured so as to have its melt surface applied bringing a thermoplastic material in its solid form into contact with a surface via mechanical extrusion; using a heater to heat the thermoplastic material to a temperature above a melting temperature of the thermoplastic material while maintaining the contact of the thermoplastic material with the surface; allowing the heated thermoplastic material to cool to a temperature that is below the thermoplastic material's melting temperature; and allowing the heated thermoplastic material to bond the hot melt apparatus to the contacted surface without a solvent or use of a curing chemical reaction when the heated thermoplastic material is cooled to below the thermoplastic material's melting temperature while remaining connected to the structural body.

Systems and methods for customizing mechanical strength in stimuli-responsive bioabsorbable materials

The disclosed technology includes a bioabsorbable material configured to be delivered to tissue. The material includes a shape-memory polymer compressible in a delivery configuration and configured to swell within a predetermined period of time. The shape-memory polymer includes one or more functional groups for reversible bonding between adjacent functional groups to transition between an approximately linear polymer and an approximately non-linear polymer upon exposure to a stimulation.

Heater for cigarette-like electronic cigarette with excellent heat transfer efficiency and manufacturing method thereof

A heater for a cigarette-like electronic cigarette and a method of manufacturing the heater are provided. The heater is provided with a heat transfer efficiency improved by strengthening a bonding force between a cigarette support portion and a heater portion by thermally pressing and bonding the cigarette support portion and the heater portion together using a heat-dissipating adhesive layer with a heat-dissipating filler added to a high-heat-resistant thermoplastic polyimide resin.

Adhesive application device and method of applying adhesive

An adhesive application device includes a coater and an air conditioning device. The coater includes a roll and a roll temperature control device. The roll has an elongated shape having an axis and outer surface and is rotatable around the axis. The roll holds thermosetting adhesive on the outer surface and applies the thermosetting adhesive to an application surface of a sheet member with the first roll being rotated and contacted with the sheet member. The roll temperature control device is disposed adjacent to the roll and configured to lower temperature of the outer surface of the roll to control viscosity of the thermosetting adhesive held by the roll to be appropriate application viscosity that is appropriate for application to the sheet member. The air conditioning device is configured to adjust temperature and humidity of air in a space near the coater.
