US Patent:

6496372, Dec 17, 2002
Filed:

Sep 26, 2001
Appl. No.:

09/964233
Inventors:

Peter A. Davison - Puyallup WA
Lee M. Langseth - Hillsboro OR
Patrick S. Johnson - Tacoma WA
Assignee:

Intel Corporation - Santa Clara CA
International Classification:

H05K 720
US Classification:

361704, 361707, 361709, 174 163, 165 803, 257718, 257719, 257727, 24453, 24297, 411508, 411509, 411510
Abstract:

The present invention relates to an electronic assembly that includes an integrated circuit package, a heat sink, and a fastener which connects the heat sink to the integrated circuit package to cool the integrated circuit package. The fastener includes a stem that extends through the heat sink and the integrated circuit package. The fastener further includes a clamp that is connected to one end of the stem and a spring head that is connected to an opposing end of the stem. The spring head includes a first biasing member that extends around the longitudinal axis of the stem to compress the heat sink and the integrated circuit package against the clamp in order to reduce the thermal impedance between the heat sink and the integrated circuit package.

US Patent:

59807911, Nov 9, 1999
Filed:

Jun 5, 1997
Appl. No.:

8/869394
Inventors:

Joseph D. Berscheid - Fergus Falls MN
Randy L. Carlson - Wahpeton ND
Jeffrey T. Gibbs - Wahpeton ND
Ronald H. Turchin - Fergus Falls MN
Kristi L. Limke - Gilbert AZ
Lee M. Langseth - Chandler AZ
Assignee:

Imation Corp. - Oakdale MN
International Classification:

B29C 5902
US Classification:

264 401
Abstract:

A method for forming a molded-in lifter for supporting a fabric liner of a flexible magnetic recording disc so that the disc is cleaned by rotation of the disc with respect to the liner when the disc is housed within a cartridge. The lifter is a raised rib that has a controlled height typically provided by deforming a molded-in rib to the desired height. The cartridge may also include a recess in the shell opposite the rib to receive the rib and prevent or reduce compression of the media if the cartridge is compressed.
