Orifice Plate With Break Tabs And Method Of Manufacturing

View page
US Patent:
6663224, Dec 16, 2003
Filed:
May 4, 2001
Appl. No.:
09/849024
Inventors:
Rio T Rivas - Corvallis OR
Garrard Hume - Corvallis OR
Angela W Bakkom - Corvallis OR
Gerald G Trunk - Monmouth OR
Niranjan Thirukkovalur - Corvallis OR
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
B41J 216
US Classification:
347 47, 298901
Abstract:
A plate has a rectangular plate body with a plurality of nozzle arrays. The plate also has first and second end zones in between the plurality of nozzle arrays and opposing ends of the plate body, respectively. There is a break tab in at least one of the first and second end zones. In between the first and second end zones is a middle zone. A plating material encapsulates the plate body in the middle zone.

Re-Usable Mandrel For Fabrication Of Ink-Jet Orifice Plates

View page
US Patent:
6790325, Sep 14, 2004
Filed:
Apr 9, 2001
Appl. No.:
09/829500
Inventors:
Craig M. Gates - Corvallis OR
Niranjan Thirukkovalur - Corvallis OR
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
C25D 110
US Classification:
204281, 428141, 428336, 428432, 428698, 347 20, 347 47
Abstract:
A method for creating a mandrel for electroforming orifice sheets with tapered bores is described. The method uses photo-imagable polymer or photoresist to create the desired profile. This is followed by electroforming a parent mandrel over which a mandrel-quality sheet of glass is melted. An array of pillars with defined location and shape is formed with a desired profile for the mandrel to be used for the electroforming process. The glass is then metalized. A photoresist mask is formed on the metalized glass and a dielectric is deposited onto the pillars.

Emission Device And Method For Forming

View page
US Patent:
6822379, Nov 23, 2004
Filed:
Oct 1, 2002
Appl. No.:
10/262808
Inventors:
Paul H. McClelland - Monmouth OR
David L. Neiman - Corvallis OR
Steven Leith - Albany OR
Niranjan Thirukkovalur - Corvallis OR
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H01J 102
US Classification:
313309, 313495
Abstract:
An emission device includes a plurality of electron emitter structures of varied geometry that have a conducting layer deposited thereon. The conducting layer has openings located at tunneling sites for each of the electron emitter structures. The tunneling sites facilitate electron emissions from each of the varied geometry electron emitter structures upon voltage biasing of the conducting layer relative to the electron emitter structures.

Fuel Cell With Embedded Current Collector

View page
US Patent:
7153601, Dec 26, 2006
Filed:
Oct 29, 2002
Appl. No.:
10/282772
Inventors:
Peter Mardilovich - Corvallis OR, US
Niranjan Thirukkovalur - Corvallis OR, US
David Champion - Lebanon OR, US
Gregory Herman - Albany OR, US
James O'Neil - Corvallis OR, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H01M 8/10
H01M 2/00
US Classification:
429 32, 429 33, 429 34
Abstract:
A fuel cell includes one or more fuel cell assemblies. Each of the fuel cell assemblies has an electrolyte having a length, an anode having a length and disposed on one side of the electrolyte, and a cathode having a length and disposed on the same or the other side of the electrolyte. The fuel cell further includes a plurality of current collectors. Each of the current collectors is substantially embedded within, and continuously extends substantially the respective length of at least one of the electrolyte, anode and cathode.

Filed:
Feb 14, 2003
Appl. No.:
10/367464
Inventors:
David Champion - Lebanon OR, US
Gregory S Herman - Albany OR, US
Peter Mardilovich - Corvallis OR, US
Niranjan Thirukkovalur - Corvallis OR, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H01M 8/04

429 35, 429 34, 429 38, 429 26
Abstract:
Subject matter includes a fuel cell with a catalytic combustor seal and related methods. The catalytic converter is positioned to come in contact with a fuel after the fuel has traversed a path over an intended electrode and the fuel is catalytically converted before the fuel can come in contact with an unintended electrode.

Fabrication And Use Of Superlattice

View page
US Patent:
7407738, Aug 5, 2008
Filed:
Apr 2, 2004
Appl. No.:
10/817729
Inventors:
Pavel Kornilovich - Corvallis OR, US
Peter Mardilovich - Corvallis OR, US
James Stasiak - Lebanon OR, US
Niranjan Thirukkovalur - Corvallis OR, US
International Classification:
G03F 7/00
US Classification:
430322, 430324, 430330, 430296, 430320, 430314
Abstract:
This disclosure relates to a system and method for fabricating and using a superlattice. A superlattice can be fabricated by applying alternating material layers on a ridge and then removing some of the alternating layers to expose edges. These exposed edges can be of nearly arbitrary length and curvature. These edges can be used to fabricate an array of nano-scale-width curved wires.
