Filed:

Sep 11, 2001

Appl. No.:

09/952164

Inventors:

Gerald V. Rapp - Escondido CA
Noah C. Lassar - San Diego CA

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

B41J 205

US Classification:

347 65, 347 93, 347 94

Abstract:

Techniques are described for constructing filter type features capable of entrapping particle contaminants to eliminate printing defects. These techniques utilize photo-imageable barrier material to fabricate various shapes and forms to reduce feature sizes. Several of these techniques utilize barrier material of height less than barrier materials used to fabricate ink feed channels and firing chamber walls. Another variation describes creation of a filter mesh from two layers of reduced height barrier materials.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

B41J 2145

US Classification:

347 40

Abstract:

A printhead assembly includes a carrier including a substrate and a substructure joined to a first surface of the substrate, and a plurality of printhead dies each mounted on a second surface of the substrate. The first surface of the substrate includes a surface deformation and the substructure is joined to the first surface by an adhesive. As such, the adhesive conforms to the surface deformation.

US Classification:

347/040000, 347/049000

Abstract:

A printhead assembly includes a carrier including a substrate and a substructure, and a plurality of printhead dies each mounted on the substrate of the carrier. The substrate includes a first material and the substructure is formed of a second material. As such, the substrate and the substructure are joined by a lap joint.

International Classification:

A61M 16/00
A61M 16/20

Abstract:

A device for placing a lung in a variety of different inflation states using positive air pressure. An exemplary device includes a housing and an air supply component. The housing includes a platform receives at least one of a synthetic lung or a real lung. The platform is at the same air pressure as a surrounding environment. The air supply component is located within the one or more internal cavities of the housing. The air supply component inflates the synthetic lung or the real lung with positive pressure.
