摘要:
In an ink-jet head having an orifice ejecting an ink for forming an image, the ink-jet head further has a water repellent film for repelling the ink on a surface of the orifice, and the water repellent film has a fluorine-containing polymer resin layer and a part having a perfluoropolyether chain or a perfluoroalkyl chain bonded on the layer, whereby an ink-jet head and an ink-jet printer having a water repellent film having high water repelling property to an oil-based ink and high abrasion resistance can be provided.
摘要:
An inkjet head having an ink flow path communicated with an ink chamber to an inkjet nozzle and having an orifice plate to which the nozzle is formed. An ink-philic layer is formed on the surface of the ink flow path, and an ink repellent layer is formed on the surface of the orifice plate where the nozzle is formed. The ink-philic layer is made of amorphous silica or inorganic polymer of colloidal silica bonded with a polymer of (SiOR), and the ink repellent layer contains a compound having perfluoropolyether chain and alkoxysilane residue as a terminal.
摘要:
An inkjet recording head characterized by better ink repellency, greater resistance to abrasion and a longer service life than a conventional product can be attained when an ink repellent layer comprising a compound made up of a perfluoropolyether chain and alkoxysilane residue is formed on the nozzle plate of the inkjet recording head. An inkjet printer for forming an image by jetting out liquid ink, wherein this nozzle plate is employed, becomes substantially maintenance free.

A substrate is provided on which wires can be formed satisfactorily using a dispersion liquid of metal microparticles without causing disconnection or short circuit. The wiring substrate comprises a substrate, an organic membrane formed on the substrate, and a metal wire formed on the organic membrane. An arithmetic mean deviation Ra of the profile of the surface of the organic membrane where the metal wire is formed is not less than 60 nm and not more than 5×10−2D, where D is the width of the metal wire. The contact angle with respect to water on the surface of the organic membrane where the metal wire is formed is not less than 110°.

A printing mechanism is provided with a counter-balanced hammer bank such that the hammer bank and a counterweight are oppositely reciprocated by a pair of cams mounted on a vertically oriented cam shaft. Vibration of the printer even at high speed can be eliminated by completely dynamically balancing the system.

The phases of distortions of a signal outputted from an amplifier are measured. A phase measurement device measures an output of an amplifier when an input signal having input frequency components ω10 and ω20 is fed to the amplifier. The phase measurement device includes multipliers for orthogonally transforming the output of the amplifier by means of ωc, a phase acquisition section for acquiring phases θ1 and θ2 of the input frequency components ω10 and ω20 in the output of the multipliers, and θ3 and θ4 (third distortion), and θ5 and θ6 (fifth distortion) of the distortion components, a match time/phase measurement section for measuring a match time point Δt when θ1 and θ2 match each other according to the acquisition result of the phase acquisition section, and a distortion component phase measurement section for measuring phases θ3 to θ6 of the distortion components at the match time point Δt according to the acquisition result of the phase acquisition section. The phase acquisition section acquires at least one of θ1 and θ2, and θ3 and θ5 (with the frequencies higher than those of θ1 and θ2) or θ4 and θ6 (with the frequencies lower than those of θ1 and θ2).
摘要:
In an electrostatic printing machine, a paper curl correction apparatus can vary the amount of curl correction provided by rotating paper guide rollers around a shaft on which paper conveying rollers are provided. As a result, angle between the shaft and a circumference of the paper guide rollers can be varied.
