Patent number: 7111929Abstract: This disclosure provides a valve which is controlled by a magnetic actuator. More specifically, the actuator is a polarized, magnetic actuator, that is, a magnetic actuator containing both a permanent magnet and an electromagnet. The actuator can be an inexpensive commercial relay having a pivoting armature that pushes a compliant diaphragm against a valve seat to close the valve. Preferably, the armature is configured as a “see-saw,” such that as the valve is opened, an opposing end of the see-saw also displaces the diaphragm. In this manner, fluid pressure in a valve chamber is relatively constant, and there are no significant pressures which prevent the valve from opening and closing. The preferred application of the valve is to actively drive printer ink supply, such that ink can be selectively drawn using the valve from a remote ink supply into a local ink reservoir, mounted near a print head.Type: GrantFiled: May 21, 2004Date of Patent: September 26, 2006Assignee: Hewlett-Packard Development Company, LPInventors: Storrs T. Hoen, Naoto Kawamura, Jonah A. Harley

Publication number: 20060131264Abstract: Pillars are formed in a fully integrated thermal inkjet printhead to prevent particles from entering into a nozzle chamber along an ink refill channel. The pillars are formed after a step of applying a thin film structure to a substrate. At one step, pits are etched through the thin film structure. At another step, material for an orifice layer is deposited into the pits. At another step, a firing chamber is etched into the orifice layer. At another step, a trench is etched into the backside of the wafer in the vicinity of the filled pits. The material filling each pit is not removed and remains in place to define the respective pillars. Two or more pillars are formed within the trench for each inkjet nozzle chamber. Alternatively pillars are formed by depositing material into the underside trench and performing photoimaging processes.Type: ApplicationFiled: February 8, 2006Publication date: June 22, 2006Inventors: Naoto Kawamura, David Thomas, David Walter, Timothy Weber

Patent number: 6997538Abstract: An inkjet printer includes a printhead having a plurality of ink orifices formed therein. During printing, ink drops are ejected through the ink orifices into a print zone between the printhead and a print medium. An air current disruption system directs an air stream through the print zone as the ink drops are ejected so as to disrupt air currents acting on the ink drops during printing and prevent print defects caused by the air currents. The air stream, however, does not disrupt an intended trajectory of the ink drops during printing.Type: GrantFiled: May 15, 2000Date of Patent: February 14, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Naoto Kawamura, John Paul Harmon

Publication number: 20060007270Abstract: Inkjet printheads capable of printing smaller and larger drop-weight quantities of ink, and methods of manufacturing the inkjet printheads, are disclosed. The inkjet printhead includes a substrate. One or more portions of the substrate may be etched such that the substrate might have different thicknesses. A thin-film layer is connected to the substrate and contains independently addressable ink-energizing elements, preferably resistors. An orifice layer having a substantially planar exterior surface is applied directly to the thin-film layer. Consequently, the thickness of the orifice layer varies with the thickness of the substrate. At least one firing chamber is defined in each portion of the orifice layer with a different thickness and, preferably, different-sized resistors. Alternatively, the orifice layer has a substantially uniform thickness. In order to achieve the multiple drop-weight capability of the present invention, firing chambers of different volumes are provided.Type: ApplicationFiled: September 14, 2005Publication date: January 12, 2006Inventor: Naoto Kawamura

Patent number: 6962406Abstract: A fluid ejection device capable of ejecting fluid onto media and a method of manufacture are provided. The device has a carrier having an upper surface that defines a recess. A fluid ejecting substrate is disposed in the recess and is configured for establishing electrical and fluidic coupling with the carrier. The fluid ejecting substrate has a generally planar orifice layer and a generally planar contact surface positioned below the orifice layer. The orifice layer extends above the upper surface of the carrier and defines a plurality of orifices therein. An encapsulant at least partially encapsulates the fluid ejecting substrate and the carrier.Type: GrantFiled: September 9, 2003Date of Patent: November 8, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Naoto Kawamura, Marvin G.

Patent number: 6918657Abstract: Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers. A phosphosilicate glass (PSG) layer, providing an insulation layer beneath the resistive layers, is etched back from the ink feed holes and is protected by a passivation layer to prevent the ink from interacting with the PSG layer. Other layers may also be protected from the ink by being etched back.Type: GrantFiled: January 30, 2003Date of Patent: July 19, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Naoto A.

Patent number: 6911155Abstract: The described embodiments relate to methods and systems for forming slots in a substrate. In one exemplary embodiment, a slot is formed in a substrate that has first and second opposing surfaces. A first trench is dry etched through the first surface of the substrate. A second trench is created through the second surface of the substrate effective to form, in combination with the first trench, a slot. At least a portion of the slot passes entirely through the substrate, and the maximum width of the slot is less than or equal to about 50 of the thickness of the substrate.Type: GrantFiled: January 31, 2002Date of Patent: June 28, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Michael D.
