摘要:
A fabrication method of a microfluidic circuit is provided, dispensable of mask registration, absent of deviation in mask positioning, and inexpensive in fabrication cost. The fabrication method of a microfluidic circuit has a light transmissive substrate stacked on a light absorptive substrate, and the light transmissive substrate welded with the light absorptive substrate for bonding by directing light through the light transmissive substrate. The microfluidic circuit includes a microchannel at the bottom face of the light transmissive substrate and/or at the top face of the light absorptive substrate. The method includes the step of forming, at the light transmissive substrate, a light attenuation region attenuating transmittance of light towards the microchannel when light is directed through the light transmissive substrate.

An electronic device may be provided with electronic device structures such as housing structures and structures associated with electrical components. The electronic device structures may be attached to each other using ultraviolet and visible light curable adhesive. A layer of adhesive may be interposed between electronic device structures. A light source may generate ultraviolet light. The structures may include an ultraviolet-light-transparent structure through which the ultraviolet light passes to illuminate and cure the adhesive. The ultraviolet-light-transparent structure may form one of multiple shots of injection molded plastic in a device structure, may be formed using a plastic that is opaque at visible wavelengths, or may have a coating such as a metal coating to help reflect ultraviolet radiation onto the adhesive. Perforations in the coating may be used to pass ultraviolet radiation to the adhesive.

Elements of photomasks may be secured using a liquid bonding material that may be cured in place. In one embodiment, a liquid bonding material may be cured using light exposure. Particularly with hard pellicles, the use of a liquid bonding material that is curable to a relatively rigid adhesion form may be advantageous since the pellicle may be positioned accurately before curing is implemented.

There is provided a joining structure of a resin member for a vehicle body and a stud bolt that can more strongly fix a stud bolt to a resin member for a vehicle body by an ultraviolet curable adhesive. Convex portions are provided at a portion, which structures a flange-adjacent portion, of a mounting surface portion of a resin member for mounting. Therefore, a surface area of adhesion with adhesive at a place, which is covered by a flange portion as seen in a plan view, of the mounting surface portion can be made to be large. As a result, adhesive force of a portion, which is cured by diffused ultraviolet rays, of the adhesive A that is covered by the flange portion as seen in a plan view can be made to be large.

Method of curing polymeric compositions using light from an electroluminescent light source. An electroluminescent wire light can be embedded into a curable polymer or adhesive composition and used for curing in circumstances in which UV or visible light from conventional lamps cannot reach the polymer or adhesive to be cured. It may also be used to cure polymer or adhesive coatings of unusual or irregular shapes. An electroluminescent wire light can be embedded in a curable adhesive or polymer compound around an irregular shape of boat hull components, and the emitted light used to cure the adhesive or polymer compound to bond the boat hull components.

摘要:
Assemblies of structures such as electronic device assemblies may be connected using light-cured liquid adhesive such as ultraviolet-light-cured adhesive. Light sources such as ultraviolet-light light-emitting diodes may be mounted to a substrate such as a printed circuit board substrate. The substrate may be mounted to an assembly formed from a plurality of structures. The structures may be connected to each other to form an interior cavity within which the substrate and light-emitting diodes are contained. A connector may be included in the assembly. The connector may have input-output pins. Conductive paths may couple the input-output pins to the light-emitting diodes in the cavity. A tool may be used to apply signals to the light-emitting diodes to activate the light-emitting diodes. The light-emitting diodes produce light that cures the adhesive. The light-emitting diodes may be disabled by blowing a fuse after the adhesive has been cured.
摘要:
A structure is provided that is at least partially adhered by a light-curable adhesive. The structure includes first and second structural components disposed in a facing relationship. The structure also includes a light-curable adhesive impregnated within at least one of the first and second structural components or disposed between the first and second structural components. The structure of this example embodiment further includes one or more side-emitting light guiding members, such as side-emitting optical fibers, positioned between the first and second structural components and in communication with the light-curable adhesive. The one or more side-emitting light guiding members are configured to emit light along a length of the one or more side-emitting light guiding members. Corresponding methods to assemble the structure and to cure the light-curable adhesive within the structure are also provided.
