    摘要： An inkjet nozzle device includes a main chamber having a floor, a roof and a perimeter wall extending between the floor and the roof. The main chamber includes: a firing chamber having a nozzle aperture defined in the roof and an actuator for ejection of ink through the nozzle aperture; an antechamber for supplying ink to the firing chamber, the antechamber having a main chamber inlet defined in the floor; and a baffle structure partitioning the main chamber to define the firing chamber and the antechamber, the baffle structure extending between the floor and the roof. The firing chamber and the antechamber have a common plane of symmetry.

    摘要： The invention described in the specification relates to an ink jet printhead structure having semiconductor substrate (12) containing energy imparting devices for ejecting ink through nozzle holes in a nozzle plate (26), to a method for making a printhead structure and to a printer cartridge containing the printhead structure. In order to reduce stresses induced in the structure during manufacturing and/or use thereof, a polymeric layer (22) is disposed between the semiconductor substrate and nozzle plate which contains expansion void spaces or valleys sufficient to inhibit stresses in the structure during a process for bonding the nozzle plate to the polymeric layer thereby reducing misalignment and warpage problems associated with conventional printhead structures.

    摘要： An ink jet recording head comprises ink paths (5) communicated with ink discharge ports (7) for discharging ink, and heat generating portions (3) arranged on the inner wall faces of the ink paths (5) for generating thermal energy utilized for discharging ink from the discharge ports (7). For this ink jet recording head, liquid-repellent treatment is processed only on the regions that correspond to the heat generating portions of the inner wall faces of the ink paths (5). With the liquid-repellent treatment processed only on the regions corresponding to the heat generating portions on the inner wall faces of the ink paths, it is made difficult for the refractory substances that may be brought about by the decomposition of colorant or the like contained in ink to be fixed on the regions corresponding to the heat generating portions. As a result, the heat of each heat generating device (3) is transferred to ink evenly to make stable ink discharges obtainable for the provision of recorded images of higher quality.
