摘要： PROBLEM TO BE SOLVED: To provide a printing head reduced in thermal and mechanical stress and a method for producing the same. SOLUTION: In a method for producing an ink jet printing head by bonding a nozzle plate to a polymer layer by heat, the polymer layer 22 is arranged between a semiconductor substrate and the nozzle plate and includes an expanding gap space or trough part sufficient to suppress the stress in a structure during the process bonding the nozzle plate 26 to the polymer layer 22. By this constitution, the problem of the positional shift and strain caused by a conventional head structure is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an ink jet printing head having filter function constitution not unjustly suppressing the ink flow passing through a printing head. SOLUTION: An ink jet printing head 10 has an ink receiving via and is equipped with a chip layer 16 having at least one actuator 18. A barrier layer is arranged adjacently to the chip layer 16 to form at least one throat 22 having width and a vertical section area. The barrier layer further forms at least one bubble chamber 20 and each throat 22 receives ink from the via to supply the same to each bubble chamber 20. A nozzle layer 14 is arranged adjacently to the barrier layer and, when ink is excited by the related actuator 18 thereof, at least one nozzle 12 for discharging ink from each bubble chamber is formed.

摘要： The invention described in the specifications relates to an improved ink jet printer cartridge structure which includes a substrate carrier (90) or nose piece upon which semiconductor devices for ink jet printheads are mounted. The substrate carrier has a top surface (100) containing one or more substrate locator wells (92) each well having well walls (98), a well base and at least one ink feed slot in each well base and side walls attached to the top surface along the perimeter thereof. One or more of the side walls contain fins (102) for heat removal from the substrate carrier and at least two alignment devices (110) attached adjacent at least one of the side walls for precisely aligning the substrate carrier in a printer carriage. Among the advantages of the substrate carrier is that it provides a suitable means for substrate alignment for multiple substrates, a means for cooling multiple substrates, a means for fixedly or removably attaching the carrier to ink reservoir body and a means for accurately aligning the carrier and reservoir body in a carriage of a printer.

摘要： An ink jet printhead includes a chip layer (16) having a via (30) for receiving ink, and having at least one actuator (18). A barrier layer (28) is disposed adjacent the chip layer, and forms at least one throat (22) which has a width and a cross-sectional area. The barrier layer also forms at least one bubble chamber (20), with each throat adapted to receive ink from the via and provide it to the respective bubble chamber. A nozzle layer (14) is disposed adjacent the barrier layer, opposite the chip layer, and forms at least one nozzle for ejecting ink from the respective bubble chamber when the ink is energized by the associated actuator. At least one post (24) is disposed proximate the throat, and extends part way between the chip layer and the nozzle layer. The post forms one or more gates through which the ink must pass from the via to the at least one throat.

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： A printhead comprises a source of ink, a body, a mounting base, and an ink heater thermally coupled to the mounting base. A flowpath delivers ink from the ink source to the heater and is defined at least in part by the mounting base on the body. Three or more thermally conductive paths extend from the mounting base to the body. Preferably, one or more of the thermally conductive paths are heat conductive bridges extending from the mounting base to the body through an edge feed via.

La capa de barrera forma también por lo menos una cámara de burbuja, estando cada estrechamiento adaptado para recibir tinta desde la vía y proporcionarla hacia la respectiva cámara de burbuja. Una capa de boquilla está dispuesta adyacente a la capa de barrera, opuesta a la capa de chip, y forma por lo menos una boquilla para inyectar la tinta desde la respectiva cámara de burbuja, cuando la tinta es energizada por el accionador asociado. Al menos un poste está dispuesto en proximidad al estrechamiento y se extiende un tramo entre la capa de chip y la capa de boquilla. El poste forma una o más compuertas a través de las cuales debe pasar la tinta desde la vía hacia el por lo menos un estrechamiento.
