The first strata includes a substrate and a heater substrata overlying the substrate and including a resistive layer having lateral portions spaced apart, a central portion extending between the lateral portions and defining the fluid heater element, and transitional portions interconnecting the central portion and lateral portions and elevating the central portion relative to the lateral portions and above the substrate to form a gap between the lateral portions and between the central portion and substrate insulating the substrate from the fluid heater element and a planar upper surface on the heater substrata. | 2010-07-01 |
| 20100165056 | Heater Stack In A Micro-Fluid Ejection Device And Method For Forming Floating Electrical Heater Element In The Heater Stack - A method for forming a floating heater element includes processing a silicon substrate to form a heater stack having the heater element on the substrate with peripheral edge portions, processing the heater stack by depositing and patterning a layer of photoresist or hard mask thereon to substantially mask the heater stack and form a trench through the photoresist or hard mask exposing a surface area of the substrate extending along the peripheral edge portions of the heater element, and processing the masked heater stack and exposed surface area of the substrate by sequentially removing the photoresist and portions of the substrate at the exposed surface area and that underlie the heater element so as to create a well in the substrate undercutting the heater element and open along the peripheral edge portions thereof, the well being capable of filling with a fluid so as to produce the floating heater element. | 2010-07-01 |
| 20100165057 | PIEZOELECTRIC ACTUATOR AND LIQUID TRANSFER DEVICE - A vibration plate, an insulating layer and a plurality of piezoelectric layers, connected to each other, are connected to an upper face of a flow passage unit. Between the plurality of piezoelectric layers, there is provided an intermediate electrode having; opposing portions opposed to center portions of pressure chambers; and connecting portions for connecting the opposing portions at a region opposed to connection portion with the flow passage unit. Between the insulating layer and one of the piezoelectric layers, there is provided a lower electrode extending across the entire region not opposed to the intermediate electrode, including regions opposed to regions of the pressure chambers located outside the center portions thereof. At an upper face of the other piezoelectric layer, upper electrodes are located to be opposed to the pressure chambers. A shielding electrode is arranged between the vibration plate and the insulating layer across the entire regions thereof. | 2010-07-01 |
| 20100165058 | Ink Refill Unit Having Discretely Incrementable Variable Storage Volume - A printing fluid refill unit for a print engine includes a reservoir having a variable storage volume for holding an amount of printing fluid, the variable storage volume having a plurality of discrete volumetric increments, each of the discrete volumetric increments having equal volumes, the reservoir further having an actuator for reducing the variable storage volume by one or more of the discrete volumetric increments; a ratchet system forming part of the actuator, the ratchet system effecting variation of the storage volume by a minimum increment of one discrete volumetric increment; an information storage element for storing information on the amount of printing fluid contained in the refill unit and for connecting with an information reader incorporated in the print engine for reading the information stored by the storage element when the refill unit is mounted to the print engine; a selector for activating the actuator to dispense a volume of the printing fluid equal to a selected multiple of the discrete volumetric increments, wherein the information stored by the storage element enables the reader to control the selector so as to derive the selected multiple of the volumetric increments; and a sensor for sensing the position of the ratchet, whereby a remaining volume of ink in the variable storage volume is determined. | 2010-07-01 |
| 20100165059 | DISPENSER UNIT FOR REFILLING PRINTING UNIT - A dispenser unit for dispensing ink to refill a supply of printing fluid in a printing unit includes a body assembly; a plurality of ink outlets provided on a bottom side of the body assembly, the plurality of ink outlets each for engaging with respective ink inlets of the printing unit; a compressible ink storage volume provided within the body assembly, the compressible ink storage volume having a sealed end and an outlet end connected to no more than one of the plurality of ink outlets; a plunger provided within the housing and abutting the sealed end of the compressible ink storage volume; and a compressing actuator for compressing the plunger against the sealed end of the compressible ink storage volume, thereby facilitating a dispensing of ink from within the compressible ink storage volume into the printing unit via the ink outlet to which the outlet end of the compressible ink storage volume is connected. | 2010-07-01 |
