Abstract:
A printhead assembly includes a molded ink manifold, a plurality of printhead integrated circuits, and an adhesive film sandwiched between the ink manifold and the printhead integrated circuits. A manifold bonding surface of the molded ink manifold includes a polymer coating. The polymer coating plugs fissures resulting from a molding process used to mold the ink manifold.
Abstract:
A method of texturizing a silicon substrate comprising a) contacting the substrate with an etching solution comprising glycolic acid, b) etching a surface of the substrate thereby forming disruptions in said surface of the substrate, and c) removing the etching solution to yield a texturized substrate, said texturized substrate having a plurality of disruptions in at least one surface with a surface density of disruptions of a minimum of 60 disruptions in a 400 micron square area.
Abstract:
A method of fabricating a film for attachment of one or more printhead integrated circuits to an ink supply manifold. The method comprises the steps of: (a) providing an adhesive polymeric film, the film being comprised of one or more photopatternable materials; (b) exposing predetermined regions of the film through a mask; and (c) developing the film to define a plurality of ink supply holes.
Abstract:
Exemplary embodiments of the invention generally include methods for forming multilayer metal interconnect structures using dual damascene methods that incorporate a via capping process to protect lower interconnection lines from etching damage or oxidation, for example, that may be caused by inadvertent exposure of lower interconnection lines to etching atmospheres.
Abstract:
A method for producing a koji of a hot pepper paste with reduced capsaicin and/or dihydrocapsaicin content through action of enzymes secreted from a koji fungus includes adding a koji fungus to starting material for preparation of koji of hot pepper paste, and adding a predetermined amount of hot peppers one or more times to the material during the cultivating step performed by enzymes secreted from the koji fungus. The method can reduce the hotness of a hot pepper paste, while maintaining the intrinsic colors of traditional hot pepper pastes. Accordingly, it is possible to prepare various hot pepper paste products satisfying customer's diverse needs.
Abstract:
The present invention relates to a fibrous 3-dimensional porous scaffold via electrospinning for tissue regeneration and a method for preparing the same. The fibrous porous scaffold for tissue regeneration of the present invention characteristically has a biomimetic structure established by using electrospinning which is efficient without wasting materials and simple in handling techniques. The fibrous porous scaffold for tissue regeneration of the present invention has the size of between nanofiber and microfiber and regular form and strength, so that it facilitates 3-dimensional tissue regeneration and improves porosity at the same time with making the surface area contacting to a cell large. Therefore, the scaffold of the invention can be effectively used as a support for the cell adhesion, growth and regeneration.
