Filed:

Oct 15, 2002

Appl. No.:

10/272519

Inventors:

Hue P. Le - Beaverton OR
Hoi P. Le - Beaverton OR
Thanh P. Le - Beaverton OR
Linh B. Tran - Aloha OR

Assignee:

PicoJet, Inc. - Hillsboro OR

International Classification:

B41J 2045

US Classification:

347 71

Abstract:

There is disclosed a piezoelectric ceramic ink-jet print head and made by an inventive ultrasonic bonding process. Specifically, there are disclosed several improved features of ink jet print heads, including a more cost-effective bonding process using an ultrasonic bonding technique, an improved piezoelectric ceramic crystal pattern, and improved print head-piezoelectric electrical contacts. Further, there is disclosed an ultrasonic bonding process joining metallic objects with ultrasonic energy.

Filed:

Jul 28, 2009

Appl. No.:

12/511007

Inventors:

Prasantha Jayakody - Seattle WA, US
Linh Dinh Tran - Shoreline WA, US
Jiaxin Wang - Redmond WA, US

Assignee:

Vulcan Technologies LLC - Seattle WA

International Classification:

G06F 17/30

US Classification:

707769, 707805

Abstract:

Embodiments of the present invention are directed to facilitating tag assignment to data objects as data objects are added to a tag-associated data-object storage system by users of the tag-associated data-object storage system and to facilitate subsequent display, access, and further characterization of data objects that already reside in the a tag-associated data-object storage system. Methods and systems of the present invention provide for automated tag suggestion to users in order to both increase usability of the interface provided to the tag-associated data-object storage systems as well as decrease the likelihood of unnecessary and unproductive tag proliferation within the tag-associated data-object storage system.

International Classification:

B41J002/045

US Classification:

347/071000

Abstract:

A piezoelectric ceramic ink-jet print head is made by ultrasonic bonding processes. Several improved features of ink jet print heads include more cost-effective bonding processes using an ultrasonic bonding technique, an improved piezoelectric ceramic structural element pattern, and improved print head piezoelectric electrical contacts. There is also disclosed an ultrasonic bonding process for joining ceramic and metallic objects.
