摘要:
A novel, nozzle member for an inkjet print cartridge and method of forming the nozzle member are disclosed. In this method, the nozzles or orifices are formed in a flexible polymer tape by Excimer laser ablation. In one embodiment, a substrate containing heating elements is mounted on the back of the nozzle member. Conductors for providing electrical signals to the substrate are located inside the flexible polymer tape and end at a via overlying an associated electrode on the substrate. The via electrically connects the conductors to the associated electrode.

An inkjet cartridge has an ink containment system for storing ink for printing. The inkjet cartridge includes a printhead having a plurality nozzles in fluid communication with the ink reservoir and an electrical interconnect for providing an electrical communication between the printhead and a printer controller. The electrical interconnect is disposed at an acute angle relative to the printhead.

An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member.

An applicator for delivering a bioactive composition includes a jet dispenser having an orifice for ejection of droplets from the dispenser. The jet dispenser further includes a main body. At least partially insertable through the main body is a replaceable fluid reservoir for holding and delivering the bioactive composition to the orifice for ejection therethrough. A body orifice spacer is positioned between the orifice of the dispenser and a target during ejection of the bioactive composition to the target.
摘要:
A printhead for an inkjet printer employs an ink fill slot having an extended portion disposed as a depression on the primary surface of the printhead substrate. The barrier layer of the printhead forms the walls of the ink ejection chambers, the walls of and constrictions in the ink fill channels, and the contoured barrier lobes between the ink fill channels. The extended portion of the ink fill slot follows the contour of the barrier lobes such that the length of the substrate shelf between the ink fill channel constriction and the extended portion of the ink fill slot is equalized between ink ejection chambers.

Disclosed is an inkjet print cartridge having an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber along a top surface of the substrate and having a first outer edge along a periphery of substrate; the first outer edge being in close proximity to the ink firing chambers. The ink firing chambers are arranged in a first chamber array and a second chamber array and with the firing chambers spaced so as to provide 600 dots per inch printing. An ink channel connects the reservoir with the ink firing chambers, the channel including a primary channel connected at a first end with the reservoir and at a second end to a secondary channel; the primary channel allowing ink to flow from the ink reservoir, around the first outer edge of the substrate to the secondary channel along the top surface of the substrate so as to be proximate to the ink firing chambers. A separate inlet passage for each firing chamber connecting the secondary channel with the firing chamber for allowing high frequency refill of the firing chamber. A group of the firing chambers in adjacent relationship forming a primitive in which only one firing chamber in the primitive is activated at a time. First circuit member on the substrate connects to the firing elements and a second circuit member on the cartridge connects to the first circuit member, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz.
