摘要： This present invention is to provide a driving circuit and method for an inkjet printhead. The driving circuit includes a group of group-driving lines, a group of column-driving lines and a group of row-driving lines. The printhead includes a plurality of driving groups which are driven by driving signals inputted in sequence via the corresponding group-driving lines. Each driving group includes a plurality of actuator and control switches which are driven by driving signals inputted via the corresponding column-driving line and row-driving line. Each control switch is just driven when the corresponding group-driving line, column-driving line and row-driving line input driving signals at the same time. Then, the driven control switch conducts the electric current to the corresponding actuator so as to jet out the ink in the ink chamber.

摘要： A structure having a base plate, such as silicon, provided with a through hole makes it possible to curtail the process numbers at the time of manufacture, while enhancing the reliability thereof. When the through hole is provided by anisotropic etching from the backside of the base plate, a silicon nitride film, which becomes membrane on the surface side of the base plate is formed so as not to allow etching solution from leaking to the surface side of the base plate. It is preferable to form the silicon nitride film using plasma CVD method to make the inner stress of the silicon nitride film a compression stress of 3×108 Pa or less.

摘要： An ink jet heater chip having improved thermal. The chip includes a semiconductor substrate, a first metal resistive, a second metal conductive layer on a first portion of the resistive layer and on a second portion of the resistive layer defining a heater resistor element. A passivation layer having a thickness defined by a deposition process is deposited on the second metal conductive layer and heater resistor element. A cavitation layer is deposited on the passivation layer and etched. A dielectric layer is deposited and etched to provide a dielectric layer overlying the first portion of the resistive layer. An electrical conduit via is etched in the dielectric layer. A third metal conductive layer is deposited in the via for electrical contact with the second metal conductive layer. Separately deposited dielectric and passivation layers enable independent control of the thickness of the dielectric and passivation layers.

摘要： There is disclosed an ink jet printhead which comprises a plurality of nozzles and one or more heater elements corresponding to each nozzle. Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through respective corresponding nozzle, to effect printing. Each heater element is in the form of a beam suspended over at least a portion of the bubble forming liquid (which liquid can be the ink) so as to be in thermal contact therewith. This configuration of printhead provides for a relatively high efficiency of operation.

There is provided an ink jet head employing an ink set including black ink and color inks, in which the black ink contains a salt, an aqueous medium and a coloring material dispersed in the aqueous medium by the function of an ionic radical, and at least one of the color inks contains a polyvalent metal salt capable, when mixed with the black ink, of impairing the dispersion stability of the coloring material in the black ink. The ink jet head has a configuration, in a portion for discharging the polyvalent metal salt containing ink used as the color ink, utilizing a discharge method in which the bubble generated in the ink in the ink flow path is opened through to the discharge port at the ink discharge.
