摘要： A method of manufacturing a water repellent member includes forming a base layer on a foundation material, forming projections on the base layer such that the projections are dispersed, and forming a water repellent film that contains a perfluoropolyether compound, and that is in contact with the base layer and the projections. The projections contain a main component whose covalent binding index is larger than a covalent binding index of a main component of the base layer.

摘要： Methods of manufacturing a volumetric continuous gradient complex dielectric element with drop-on-demand techniques, such as inkjet printing, by calculating spatial placement of nanocomposite-ink droplets are disclosed. The methods comprise determining or having a multi-dimensional gradient profile representing a volumetric gradient complex dielectric element. Providing or having a plurality of nanocomposite-inks, at least one of the nanocomposite-inks having a curable organic-matrix and a concentration of nanoparticles dispersed within to print the volumetric continuous gradient complex dielectric device. A print mask is determined in one-, two-, or three-dimensions that reconstructs the multi-dimensional gradient profile as a discretized pattern based on the material properties of the plurality of nanocomposite-inks and properties of a printing apparatus with a plurality of printheads. A spatial or spatio-temporal print schedule is determined that results in an at least approximate reproduction of the gradient profile when printed with the printing apparatus.

摘要： At least one embodiment of a liquid discharge head includes a liquid discharge substrate, a support substrate on which a back surface of the liquid discharge substrate is joined, and a wiring substrate. A second edge of the liquid discharge substrate and at least one third edge that forms a surface of the support substrate and is in contact with the back surface of the liquid discharge substrate, intersect at an intersecting point. A sealing agent for sealing an electric connection portion between the liquid discharge substrate and the wiring substrate extends over a portion of the second edge extending toward at least one second side surface of the liquid discharge substrate from a space on a lower side of the electric connection portion, to reach at least the intersecting point.
