US Patent:
20110205303, Aug 25, 2011
Filed:
Oct 14, 2008
Appl. No.:
13/063438
Inventors:
Alfred I-Tsung Pan - Sunnyvale CA, US
Erik D. Torniainen - Albany OR, US
Assignee:
HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. - Houston TX
International Classification:
B41J 2/05
US Classification:
347 61
Abstract:
In one embodiment, a fluid ejector structure includes: a chamber; a bridge spanning at least part of the chamber; a channel through which fluid may enter the chamber; a fluid ejector element on the bridge; and an outlet through which fluid may be ejected from the chamber at the urging of the fluid ejector element. The outlet is disposed opposite the fluid ejector element across a depth of the chamber and the chamber, ejector element and outlet are configured with respect to one another such that substantially all of the fluid in the chamber is ejected through the outlet upon actuation of the ejector element.

Thermal Inkjet Printhead Feed Transition Chamber And Method Of Cooling Using Same

View page
US Patent:
20110227987, Sep 22, 2011
Filed:
Oct 30, 2008
Appl. No.:
13/124085
Inventors:
Alfred I-Tsung Pan - Sunnyvale CA, US
Daniel Fradl - Palo Alto CA, US
Erik D. Torniainen - Albany OR, US
International Classification:
B41J 29/377
B41J 2/05
US Classification:
347 18, 347 65
Abstract:
A thermal inkjet printhead and a method of cooling convectively cool the printhead with ink passing through a feed transition chamber. The thermal inkjet printhead includes a bridge beam and feed channels adjacent to the bridge beam. The printhead further includes a feed transition chamber between inputs to the feed channels and an ink reservoir. The ink flows through the feed transition chamber between the ink reservoir and the feed channels to convectively cool. The method of cooling includes providing the feed transition chamber and flowing ink through the feed transition chamber from the ink reservoir to the feed channels. The flowing ink establishes a temperature gradient between walls of the feed transition chamber and the ink. The temperature gradient facilitates convective cooling of the printhead.

Assignee:
HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P. - Houston TX
International Classification:
B41J 2/175
US Classification:
347 85
Abstract:
A fluid ejection assembly includes a fluid slot, and a group of uniformly spaced drop generators, where each drop generator is individually coupled to the fluid slot through a first end of a drop generator channel and to a connection channel at a second end of the drop generator channel. The fluid ejection assembly includes a pump disposed within a pump channel located between two drop generator channels, and is configured to circulate fluid from the fluid slot, into the connection channel through the pump channel, and back to the fluid slot through the drop generator channels.
