    Abstract: PROBLEM TO BE SOLVED: To provide a design of a stepped nozzle in which an ink droplet size can be regulated independently from droplet velocity and the necessity of the complicated design optimization is reduced.SOLUTION: An inkjet printer includes: a print head configured to receive ink; and one or more stepped nozzles provided with the print head. The one or more stepped nozzles have an exit diameter which is set so as to regulate the droplet size of ink to be ejected and an entrance diameter which is set so as to regulate the velocity of the ink droplet to be ejected independently from the size of the ink droplet to be ejected.

    Abstract: PROBLEM TO BE SOLVED: To provide an inkjet printing system that independently control the mass and speed of ink liquid drops ejected from an inkjet print head.
    SOLUTION: A taper angle 330 depends on relationships among an exit diameter 310, an inside diameter 315, and/or thickness 325. For example, when the thickness 325 is fixed, the taper angle 330 can get larger as the difference between the exit diameter 310 and the inside diameter 315 is increased. Likewise, when the thickness 325 is fixed, the taper angle 330 can get smaller as the difference between the exit diameter 310 and the inside diameter 315 is decreased. The different values of and adjustments among the exit diameter 310, the inside diameter 315, the thickness 325, and the taper angle 330 can dictate the mass and speed of ink liquid drops that exit the nozzle 305. Further, they can allow the mass and speed of liquid drops to be independently dictated by the exit diameter 310 and the taper angle 330, respectively.

    Abstract: PROBLEM TO BE SOLVED: To open many port holes on the surface at a side opposite to outlet apertures so that high resolution printing can be performed and ink leakage and clogging may not occur. SOLUTION: On the port hole opening surface prepared is a jet stack 102 so that a plurality of the port holes 106 are opened. A piezoelectric array 110 which is planarized by filling the space between the piezoelectric elements with a polymer is adhered to the port hole opening surface of the stack 102 so that the opening of the port holes 106 may be closed by the polymer between the elements. The port holes 106 are extended through the polymer between the elements by partially ablating the polymer between the elements from the outlet aperture surface side of the stack 102 using a laser beam and using the stack 102 as a mask. An opening plate 130 is adhered to the outlet aperture surface side of the stack 102 to form an outlet port second section 138 which communicates with via holes 142 of a circuit board 140 through the port holes 106.

    Abstract: PROBLEM TO BE SOLVED: To surely form a die attach and an interface at a low cost. SOLUTION: A multi-layered film 20 composed of a plurality of film layers having a required thickness including an uppermost upper film layer 22 and a lowermost lower film layer 28 is formed and arranged on the upper surface of a substrate 30 having an inner structure. A through passage 401 in the multi layered film for fluidly coupling an upper surface opening 420 of an upper film layer and a lower surface opening of a lower film layer, and traverse passages 402, 403 in the multi layered film for fluidly coupling upper surface openings 421 to 426 of the upper film layer for every group are formed with hollow cavity portions having no film material provided in the respective film layers so as to be opened on both of the upper and lower surfaces. On the other hand, the substrate 30, the film layers 28, 22, and a device 600 are fluidly coupled by forming a passage 301 to be fluidly coupled with the through passage 401 in the substrate 30 by fluidly coupling an upper surface opening of the substrate and a front surface opening 312 of the substrate, etc. The device 600 is fluidly coupled with the upper surface openings 420 to 426 of the upper film layer.

    Abstract: PROBLEM TO BE SOLVED: To manufacture a print head provided with a nozzle plate face which is processed with laser abrasion, and is hydrophobic or is covered with a hydrophobic coating film. SOLUTION: This method comprises a step of forming an article composed of one or more layers and a step of processing this article using a laser having a wavelength of between about 210 and about 360 nm. At least one of the layers comprises a hydrophobic fluorine-containing graft copolymer derived from at least one kind of fluorine-containing monomers and at least one kind of comonomers that contain at least one aromatic group. This graft copolymer has absorption for radiation of the above-mentioned wavelength range. The article formed with the laser abrasion includes the nozzle plate for an ink jet print head, and this nozzle plate is provided with ink jet openings formed through the laser abrasion and has a polymer substrate coated with the hydrophobic fluorine-containing graft copolymer which permits the laser abrasion.

    Abstract: PROBLEM TO BE SOLVED: To compensate an unforeseeable-size gap along a linear array of a photosensor by using a simple algorithm. SOLUTION: There is provided an improved ink jet head having an ink reservoir set in an ink jet channel. The arrangement improves the wait time of a printing head and broadens a range of inks which can be used suitably. In one alternative, the ink reservoir is set between a heater and a face of the printing head and is actually an expansion of a heater pit. In another embodiment, this is achieved by shifting a front edge of the heater pit set to a thick polyimide (or the other photosensitive resin) layer held between the heater chip and an ODE channel chip.

    Abstract: PROBLEM TO BE SOLVED: To provide an ink-jet print head equipped with an ink-repellent coat which is abrasion resistant and hard to wear under the action of a wiper blade normally used at a maintenance part of an ink-jet printer. SOLUTION: An ink-jet print head 10 includes a plurality of channels. The channels can be replenished with ink from an ink source. Terminal ends of the channels become nozzles 27 at on surface of the print head 10. The surface has a covalent bonded organosiloxane polymer coat. The organosiloxane polymer coat is substantially uniform and has no further layer thereon.
