A novel, wide inkjet printhead and method of forming said inkjet printhead is disclosed, wherein a pattern of orifices are formed, using a step-and-repeat process, in a flexible tape using laser ablation or other suitable etching means. The location of the orifices corresponds to where ink will be ejected from the inkjet printhead. The pattern of orifices may extend to any length without difficult...

This invention provides an improved ink seal between a print cartridge body and an inkjet printhead. In a preferred embodiment, a nozzle member containing an array of orifices has a substrate, having heater elements formed thereon, affixed to a back surface of the nozzle member. Each orifice in the nozzle member is associated with a single heating element formed on the substrate. The back surface ...

In a printhead according to the preferred embodiment of the invention, a polymer tape having orifices formed therein and containing conductive traces is provided with one or more windows exposing ends of the conductive traces. A separate substrate contains heating elements and electrodes. A conventional, commercially available automatic inner lead bonder is then used to automatically align the ori...

In one of the preferred embodiments, an inkjet printhead includes a nozzle member formed of a polymer material that has been laser-ablated to form inkjet orifices. The nozzle member also has formed on it conductive traces for supplying electrical signals to heating elements on a substrate mounted to a surface of the nozzle member. In a preferred method, the orifices are formed by Excimer laser abl...

In one of the preferred embodiments, an inkjet printhead includes a nozzle member formed of a polymer material that has been laser-ablated to form inkjet orifices, ink channels, and vaporization chambers in the unitary nozzle member. The nozzle member is then mounted to a substrate containing heating elements associated with each orifice. In a preferred method, the orifices, ink channels, and vapo...

A control unit in a sorting system with a rotary sorting conveyor requires a very large capacity in order to be able to hold all the data associated with the sorting of the items introduced. In the case of the invention the relevant sorting data are transmitted to the control unit 22 of the individual conveyor sections, and these units therefore relieve the load on the fixed control system to a c...

A drug delivery catheter assembly, including an expandable, porous outer membrane that is insertable into a blood vessel and positioned adjacent a stenotic atherosclerotic lesion on the interior wall of the blood vessel. The membrane is expanded into contact with the lesion, either mechanically or hydraulically. After the membrane is expanded, a drug-containing liquid is caused to flow into the me...

This invention provides an improved ink flow path between an ink reservoir and vaporization chambers in an inkjet printhead. In the preferred embodiment, a barrier layer containing ink channels and vaporization chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two linear arrays of heater elements, and each orifice in the...

A heat-distributing mounting system for clamping heating/cooling pipes on pipes for liquid or gaseous media. The system consists of one or more metal profiles which hold the heating/cooling pipes over the full pipe length and are clamped to the medium pipe by means of plastic spacers and clamping bands. Figure 6 shows the system in a finished pipe construction. The heating/cooling pipes 1 are reta...

A method for sealing a tray (1) by means of a lid (3), the lid consisting of a paperboard material, and the tray of a plastic material or of a plastic-laminated paperboard and being particularly intended for storing and heating food. The lid (3) is provided with an opening (6) and is adhesively secured to a plastic film (7). The lid is then, together with its plastic film, welded to the tray. The ...
