Abstract:
An apparatus for interfacing materials and absorbing disparate thermal expansions thereof utilizes a woven wire mesh to support a predetermined thickness of a first soft solder which absorbs expansions, and utilizes a second soft solder having a lower melting point than the first to coat the surfaces of the wire mesh/first soft solder combination so that the materials can be bonded thereto.
Abstract:
Electrically conductive bodies and methods of using same are disclosed which generally incorporate the feature of wire crossing wire at multiple sites of mutual contact throughout the body with the wire interconnected at the sites by a chemical deposition of metal to yield a rigid, open metallic lattice.
Abstract:
In a known hot melt screen printing machine the printing ink is heated by an electrical current which is conducted through a stainless steel mesh of a screen plate. In the known machine, the printing accuracy is not good, mainly because of variation of tension and thermal expansion of the mesh.The mesh according to the present invention consists of insulating material fibers and an electroless plating layer formed on the fibers. The plating layer preferably consists of a nickel phosphorous alloy. A squeezing means for forcing the printing ink to pass through a printing pattern and/or a printing base for mounting an article to be printed are provided with a heating means. One of the advantages of the present invention is a high printing accuracy.

Abstract:
A staking electrical contact for staking an electrical conductor onto a printed circuit board and in electrical engagement with a printed circuit path on the printed circuit board which comprises a body portion having spaced legs between which the electrical conductor is disposed and the legs are driven into slot means of the printed circuit board until the contact is bottomed whereupon the free ends of the legs are bent into engagement with the printed circuit path and soldered thereto.
Abstract:
A machine knittable hybrid yarn is disclosed. The hybrid yarn includes one or more electrically non-conductive yarns and two or more electrically conductive wires wrapped around the electrically non-conductive yarns. The electrically conductive wires have an exterior layer of an insulated material. The electrically non-conductive yarns include a majority fraction of an overall cross-section of the hybrid yarn. The two or more electrically conductive wires are wrapped around the one or more electrically non-conductive yarns at between 1 and 15 twists per inch. The one or more electrically non-conductive yarns are 1500 denier or finer.
Abstract:
A laser system includes a femtosecond laser; and a scanner configured to irradiate laser beams, which are outputted from the femtosecond laser on fabric, according to a graphene pattern. An electronic textile with graphene patterned on the fabric is manufactured by the laser beams. The graphene pattern and a structure of the fabric are differently determined depending on applications of the electronic textile.
Abstract:
In one aspect the invention provides an electromechanical device having a conductive component which is stretchable and having a conductive lead to connect the component to an electrical circuit. The conductive lead may be arranged as threaded through the component at multiple locations on the component layer to integrate the lead with the component. Aspects provide a laminated capacitor formed of elastic material with first and second elastic electrode layers. The conductive lead may comprises an inner conductor and an outer conductor arranged to cover the inner conductor. A length of exposed inner conductor is arranged threaded through the first component and an exposed length the outer conductor is arranged threaded through the second conductive component.
Abstract:
Strands of material may be intertwined using weaving techniques, knitting techniques, non-woven or entanglement techniques, or braiding techniques. Fabric that is formed from the strands of material may be used in forming a fabric-based item. The fabric based item may include electrical components. The strands may include conductive strands that form signal paths. The signal paths can carry electrical signals associated with operation of the electrical components. Each strand may have an elongated core and a coating. Strands may also include intermediate layers between the cores and coatings. The cores, intermediate layers, and coatings may be formed from polymer without conductive filler, polymer with conductive filler, and/or metal. A polymer core may be provided with recesses to help retain subsequently deposited layers such as a metal coating layer. The recesses may be grooves that extend along the longitudinal axis of the core.
