US Patent:

6475064, Nov 5, 2002

Filed:

Jun 26, 2001

Appl. No.:

09/892039

Inventors:

Shanlin Hao - Eden Prairie MN
Lars Halvar Ahlen - Bloomington MN
Edward Michael Erickson - Apple Valley MN

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

B24B 4900

US Classification:

451 5, 451 41, 451279, 29593

Abstract:

An actuator adapted to adjust the profile of a carrier supporting a bar relative to a lapping surface. The carrier including a plurality of spaced control or actuation points along the length of the carrier for adjusting the profile of the mounting surface of the carrier adapted to support a bar for lapping. The actuator adapted to actuate the carrier at the spaced actuation points and including a plurality of actuation members movably actuated via pressure supplied to the actuation members. The actuation members are supported in spaced staggered relation in chambers in a manifold for bidirectional actuation. The actuation members are spaced relative to the spaced actuation points and are supported relative to the manifold to provide precision actuation for incrementally adjusting the profile of the carrier.

International Classification:

B24B 4900

US Classification:

451 5, 451 8, 451 9, 451 10, 451279, 2960316

Abstract:

An interfaced carrier assembly including an interface circuit having printed contacts to provide electrical interface or feedback control for lapping operations. The printed contacts are formed on a base material on the interface circuit and interface with terminal pads on a slider bar supported by a carrier plate for lapping feedback control. The interface circuit is assembled with the carrier plate with contacts on the interface circuit aligned with terminal pads on the slider bar supported by the carrier plate. Alignment of the terminal pads on the slider bar and contacts on the interface circuit are measured by digital cameras for assembly of the interfaced carrier assembly.

Assignee:

Riker Laboratories, Inc. - Northridge CA

International Classification:

C07D21524

US Classification:

546169

Abstract:

Filed:

Aug 25, 1975

Appl. No.:

5/607626

Inventors:

Larry R. Lappi - Stillwater MN
Edward H. Erickson - Woodbury MN

Assignee:

Riker Laboratories, Inc. - Northridge CA

International Classification:

C07D49522

US Classification:

260287C

Abstract:

4-Hydroxy[1]benzothieno[3,2-f]quinoline-2-carboxylic acids and esters thereof are prepared by the reaction of an optionally substituted 2-aminobenzothiophene with dimethyl acetylenedicarboxylate followed by ring closure. The sulfur atom of the intermediate compounds in the process can be oxidized to oxide or dioxide state, then hydrolyzed to the acids, or first hydrolyzed to the acids and then oxidized, if desired. The acids are physiologically active as anti-allergic agents in the acid form or as salts.
