Abstract:
A printing method comprises a step of designating a prescribed area of an ink-coating surface as a surface modification area; a step of coating said designated area with a surface modifier by an ink yet head; a step of transferring to another position said area of said ink-coating surface coated with said modifier in order to dry said surface modifier; and a step of returning said ink-coating surface, in which said surface modifier is dried, to the position where said surface modifier was supplied, and expelling ink on said ink-coating surface by an ink jet head on the basis of ink expelling information from a computer.
Abstract:
A piezoelectric thin film having good properties, for example, a high dielectric constant and a high piezoelectric strain constant is disclosed. Further, a method for producing the same which does not suffer from cracks at the time of annealing is also disclosed. The piezoelectric thin film according to the present invention comprises a thin film with the average grain area of crystal grains observed on the surface of the thin film being not less than 0.1 mu m , the thin film having no multilayer structure in its cross section. The method for producing the piezoelectric thin film is based on a sol-gel process and comprises the steps of: coating a substrate with a sol composition comprising a sol, of a metal component for constituting a piezoelectric film, and a polymer compound and then drying the coating to form a film; pre-sintering the film to form a porous thin film of gel comprising an amorphous metal oxide; pre-annealing the porous thin film of gel to convert the film to a film of a crystalline metal oxide; repeating the steps at least once to form laminated films of a crystalline metal oxide; and annealing the films thus prepared to grow crystal grains of perovskite type in the film into a larger size.
Abstract:
In an ink jet printer head which ejects ink drops from a nozzle (11) formed on the surface of the nozzle plate 1, wherein a metal layer (13) and a sulfur compound layer (14) are formed on the surface of the nozzle. Gold atoms of the metal layer (13) and sulfur atoms of the sulfur compound layer (14) are bonded covalently and form a water repellant thin film. Since ink does not remain on the nozzle surface, problems such as ink drops being pulled by residue ink and the ejection direction of ink drops being bent are eliminated.
Abstract:
This invention consists in an ink flow passage having on the surface thereof a film whose surface is composed of fine particles of inorganic oxide containing a hydrophilic group. The surface of ink flow passage of this invention is high in hydrophilic properties and enables quick removal of bubbles developing in the flow passage. A printing head of this invention does not require liquid charging during conveyance as has been required by the conventional head, and can be conveyed empty.
Abstract:
A method for forming a silicon film which comprises discharging an ink composition (11) selectively onto a predetermined region of a substrate using an ink jet head (12) to form a pattern of a silicon precursor, and then subjecting the pattern to a treatment by heat and/or light to convert the silicon precursor to an amorphous silicon film or a poly-crystal silicon film. The method can be used for providing a silicon film pattern on a large area portion of a substrate with saving energy with a low cost.
