A method for joining a fastener to a workpiece. The method comprising the following steps. Providing a fastening element including: a shaft-shaped anchor section which extends between a first end and a second end along an anchor axis; a flange formed on and extending radially to the first end of the anchor section, and the flange at least partially forms an application section, and; a joining material pre-applied to the application section and lying in an at least partially solid state, and wherein the joining material includes a first adhesive material and a second adhesive material. Providing a workpiece including a carrier surface. Arranging the fastening element on the carrier surface. Mixing the first and second adhesive materials by rotating the fastening element. And, joining the fastening element to the workpiece via the cross-linking reaction of the first and second adhesive materials.

A method for bonding fibers includes providing a first fiber layer and a second fiber layer positioned below the first fiber layer to bond the first fiber layer with the second fiber layer. The method may also include providing a first additive layer. The first additive layer is located between the first fiber layer and the second fiber layer. Then, the method may further include activating the first additive layer by directing energy at the first additive layer.

A fluid leak repair kit, comprising: a putty; a self-amalgamating tape; and a composite material for use in encompassing the self-amalgamating tape, said composite material comprising a flexible sheet or tape and a matrix component for binding the flexible sheet or tape, the matrix component comprising a resin or water-activated matrix component which, when cured, forms an outer shell.

A packaging method and a display device are disclosed. The packaging method includes: packaging a display element on a substrate having the display element disposed thereon to form a package covering the display element, wherein a first substance is disposed on at least a part of the substrate inside the package, the first substance including thermite; and initiating the first substance to obtain a second substance including a product of the thermite reaction.

A three-dimensional object comprises substantially planar or flat substrate layers that are folded and stacked in a predetermined order and infiltrated by a hardened material. The object is fabricated by positioning powder on all or part of multiple substrate layers. On each layer, the powder is selectively deposited in a pattern that corresponds to tiles that each have a slice of the object. For each slice, powder is deposited in positions that correspond to positions in the slice where the object exists, and not deposited where the object does not exist. The tiles of each substrate layer are folded and aligned in a predetermined order. Multiple folded substrate layers mat be combined into a single stack. The powder is transformed into a substance that flows and subsequently hardens into the hardened material in a spatial pattern that infiltrates positive regions, and does not infiltrate negative regions, in the substrate layers.

The present subject matter provides an adhesive article having a release agent or liner that is free of silicon-containing and fluorine-containing material, and related methods of adhering a backing material of the adhesive article to a substrate. The adhesive article utilizes an amorphous polyvinyl alcohol layer that facilitates removal of an optional release liner from an adhesive layer. Upon removal of the release liner, the amorphous polyvinyl alcohol layer remains disposed on the adhesive layer. A method of adhering the backing material to a substrate includes dissolving the amorphous polyvinyl alcohol layer and disposing the backing material to a substrate. During dissolution of the amorphous polyvinyl alcohol layer, a weak, temporary bond is formed between the substrate and the backing material. When the amorphous polyvinyl alcohol layer substantially dissolves and dries, the adhesive layer is exposed and forms a permanent bond with the substrate.

The present subject matter provides a shrink film free of silicon-containing material, fluorine-containing material, and solvent-formed seams. The shrink film utilizes a water soluble layer covering an adhesive layer. The water soluble layer is in dry form and non-tacky, allowing processing of the shrink film subsequent to adhesive application to the shrink film. When the water soluble layer is dissolved, the adhesive layer is exposed and is capable of forming a permanent bond. The adhesive can be used to form a seam in the film and/or can be used to form a bond between the film and a substrate. The water soluble layer facilitates removal of an optional release liner from the adhesive. A substrate with the shrink film attached thereto and a related method of attaching a heat shrinkable film to a substrate are also disclosed.

A stimulation or recording electrode with varying impedances includes a plurality of layers that are compressed together with varying compressions forces, with at least a first compression force used at the perimeter of the electrode and a second compression force used towards the center of the electrode, with the first force being lesser than the second force, thereby creating a greater measured impedance at the perimeter of the electrode than at the center of the electrode.

Disclosed is a method for producing a joined body obtained by joining a base material A, a solid joining agent containing an amorphous thermoplastic resin, which is at least one of a thermoplastic epoxy resin and a phenoxy resin, as a main component, and a base material B in this order, in which at least the base material A is a thermoplastic resin base material, an epoxy equivalent of the amorphous thermoplastic resin is 1,600 g/eq. or more or the amorphous thermoplastic resin does not contain an epoxy group, and a heat of fusion of the amorphous thermoplastic resin is 15 J/g or less, and the method has a step of superposing and a joining step (1), or has a joining step (2-1) and a joining step (2-2).
