摘要： An ink jet recording head includes a recording element base plate having an ink heating portion for heating ink, and ink discharge ports for discharging ink heated by the ink heating portion; a main body portion having an ink supply path for inducing ink from an ink retaining portion; and a connecting member having a first bonding surface bonded to the main body portion, and a second bonding surface bonded to the recording element base plate. For this head, the connecting member is formed by material having a weaker stretching strength than that of the recording element base plate. With the structure thus arranged, it is possible to provide an ink jet recording head capable of printing high-quality images at all times without deforming the recording element base plate due to the difference in the bonding temperature of the recording element base plate and room temperature, or due to temperature changes at the time of driving, even if the number of nozzles increases and the recording element base plate is made longer.

摘要： A page width printhead assembly (1) for a digital inkjet printer has a support member that can be secured in the printer, and a printhead (2) that can be mounted to the support member. The support member has a core with at least one ink reservoir (6, 7, 8 and 9) enclosed within a laminated shell (4). The materials and structure of the shell (4) and the core (5) are selected and configured so that the co-efficient of thermal expansion of the support member as a whole is substantially equal to that of the printhead (2).

摘要： A thermal bend actuator includes a wafer substrate. An elongate actuator arm is fixed to the substrate at a fixed end. The elongate actuator arm includes a heater layer of a conductive material and a dielectric, resiliently flexible layer. The heater layer defines a heater circuit which is connected to an electrical potential. A working member is fixed to an opposite free end of the actuator arm. Control logic circuitry is positioned on the substrate, between, and generally aligned with, the heater layer and the substrate. The control logic circuitry is interconnected between a data input means and the heater circuit and includes register circuitry connected to the data input means to generate an enabling signal. Firing circuitry is connected between the register circuitry and the heater circuit to close the heater circuit on receipt of the enabling signal so that said electrical potential generates a current in the heater circuit, resistively to heat the heater layer. At least the heater layer is of a material that has a coefficient of thermal expansion which is such that the heater layer can expand on heating and contract on cooling to do work. The heater layer is positioned so that the elongate actuator arm experiences differential thermal expansion and contraction and thus reciprocally displaces the working member.

摘要： This patent describes ink jet printing device that utilizes a shape memory alloy such as a nickel titanium alloy for ejecting drops. The ejection involves utilization of the transformation of a shape memory alloy from its martensitic phase to its austenitic phase (or visa versa) as an actuator to cause the ejection of ink from the the chamber. The actuator is normally in its quiescent state and transfers to an ink injection state upon heating thereby causing ink ejection from the chamber. The heating occurs by passing a current through the shape memory alloy. The shape memory alloy can be conductive and arranged in a serpentine form for operation. The actuator being formed above a crystallographically etched nozzle chamber having a nozzle port from which ink is ejected.

摘要： An ink-jet head, a manufacturing method thereof, and an ink-jet recording apparatus, in which a substrate low in price, easy to handle and large in size can be used to thereby improve the productivity. Individual electrodes (101) are formed on an electrode glass substrate (100), and covered with an insulating film (202). A sacrificial layer (110) is formed on the insulating film (202), and diaphragms (201) are formed thereon. Window portions (212) are provided in support portions of the diaphragms (201). The sacrificial layer (110) is etched through the window portions (212) to thereby form an electrostatic actuator structure. After that, to close the window portions (212), Ni is deposited all over the surface again, and thereafter the Ni film is patterned to thereby form partition base portions (213). Cavity partitions (214) are formed by Ni electrocasting, and a nozzle plate (300) is bonded therewith.
