US Patent:

Filed:

May 17, 2002

Appl. No.:

10/147638

Inventors:

Steven Marcangelo - No. Chelmsford MA
Robert T. Norton - Tewksbury MA

Assignee:

LP Property Management Company - South Gate CA

International Classification:

D05B 1100

US Classification:

11247501, 112 21, 11247508

Abstract:

A clamping system for a sewing machine used to sew first and second materials together. The clamping system has a plurality of clamps mounted adjacent an opening in a frame. Each of the clamps has a stationary member, a movable member and an actuator. The actuator is connected to the movable member and operates to move the movable member in a clamping relationship with the stationary member to clamp the first material in the clamp. The clamp is powered by a cylinder with a linear stroke, and the clamp has a driving member that transfers the linear motion of the cylinder into a pivoting motion of the movable member. Further, the movable and fixed members have forward ends shaped so that they hold the first material but do not interfere with a sewing of the first member to the second member.

International Classification:

H01L 29/423
H01L 29/78
H01L 29/06

Abstract:

The present disclosure addresses thermal issues in a multi gate finger field-effect transistor (FET) by providing a multi-gate finger FET arrangement where the respective distances between the multiple gate fingers are modulated along the device, such that the distances between the gate fingers in or towards the middle of the device are greater than the distances between the gate fingers at the or towards the edge of the device. By providing the greater distances between gate fingers located in or towards the middle of the device then improved thermal management properties are obtained, and the device as a whole is maintained cooler than would otherwise be the case, with associated improvements in device lifetimes.
