摘要： A method of manufacturing a bubble-jet type ink jet printhead. The method includes forming resistive heater elements on a substrate, forming a patterned electrode layer on the resultant structure, forming an insulating layer over the resultant structure, forming barrier walls on the resultant structure and attaching a nozzle plate on the resultant structure. The method may further include etching a hole in the insulating layer, forming a second electrode layer over the etched insulating layer to contact the resistive heater elements and forming a second insulating layer thereon, where the barrier walls and then the nozzle plate are formed on top of the second insulating layer. The barrier walls group together resistive heater elements in pairs and form barriers between different pairs of resistive heater elements.

摘要： An ink jet recording head is provided with one heat generating member in each of ink flow paths, and the discharge port thereof is arranged on the extended line extending in the normal direction from the center of the main surface of the heat generating member to the surface of the substrate. Then, on the surface of the substrate, non-bubbling area is provided on the center within the projected area having the discharge port projected thereon. Bubble brought to the boil by the heat generating member pushes out ink from the discharge port by the pressure exerted by the bubble, while being communicated with the outside. With the structure thus arranged, it is made possible to enhance the precision of discharge direction of the liquid droplet discharged from the discharge port.

摘要： A bubble-jet type ink-jet printhead is provided. The bubble-jet type ink-jet printhead includes a substrate, a plurality of chamber walls arranged parallel to one another on the substrate for dividing a chamber into a plurality unit chambers having a predetermined height, which are ink flow areas, a bubble generating means, provided for each unit chamber, which includes two unit heaters spaced apart by a predetermined distance on the substrate, and a nozzle plate, combined above the substrate, in which a plurality of nozzles are formed, each nozzle corresponding to a region between the two unit heaters of each bubble generating means. In this case, ink is supplied from both sides of the unit chamber. The ink-jet printhead is constructed such that a unit chamber is provided for each nozzle and bubbles are generated chamber on both sides of a nozzle within the unit chamber, thereby effectively preventing a back flow of ink while facilitating adjustment of the size of ink droplet ejected through the nozzle. Furthermore, the ink-jet printhead allows for high-speed and high-pressure ink ejection with relatively low pressure compared to a conventional printhead. In particular, an ink channel having a simple structure is provided, thereby avoiding the clogging of the ink channel due to foreign materials while effectively preventing defectiveness of the printhead.

First orifices of the first nozzles and second orifices of the second nozzles are formed on the orifice layer. The jet has at least one of following characteristics: (a) the first chambers are larger than the second chambers; (b) an interval between two heating units of the first nozzle is larger than an interval between two heating units of the second nozzle; and (c) the apertures of the first orifices are larger than the apertures of the second orifices.

摘要： An ink-jet head for ejecting ink droplets from a nozzle by the pressure caused by bubbles, includes: a pressure chamber; a multiple number of heating areas for generating bubbles inside the pressure chamber. Heater films arranged in the heating areas are electrically connected in parallel. The thermal conductivity of the insulating film in each heating area is made different from that of the other heating areas so as to produce difference in thermal efficiency between the surfaces facing the pressure chamber so that the heating area closest to the nozzle has the highest thermal efficiency. As a result, heating areas where bubbles should be generated can be selected by varying the applied energy level, whereby it is possible to perform multilevel control of the ejected amount of ink droplets.
