Title: Sport Boot Liner and Method for Making Same
Inventor: LANG HERBERT
IPC: A43B19/00
Filed: 1993-11-04
Abstract: A liner (20, 120) for a sport boot shell (25) and a method for making a custom fitted liner (20, 120) for a sport boot, are disclosed. Liner (20) is designed to be worn inside a boot shell (25). In a preferred embodiment liner (20) includes inner and outer flaps (34, 36) which wrap in opposite directions across a wearer's shin and form a compound curve in a region (80) in front of the wearer's ankle. The liner (20), including flaps (34, 36), may be made from a single piece of thermoplastic foam material (42) of uniform thickness. The design of the liner prevents the cuff (38) of the liner (20) from loosening around the wearer's shin and calf when the wearer's leg is flexed forward at the ankle. The shell (25) can therefore be worn more loosely than is necessary with a boot liner of conventional design. Liner (20) may be made by making an unfitted liner (60) from a sheet of thermoformable material (42). Unfitted liner (60) has a forwardly facing opening (63) and wings (64, 66) extending forwardly on either side of opening (63). Unfitted liner (60) is then heated to above the thermoforming temperature of material (42) and simultaneously fitted to sheell (25) and the wearer's foot and leg by the steps of: placing the wearer's foot into unfitted liner (60); forming flaps (34, 36) by wrapping wings (64, 66) across the wearer's shin; holding unfitted liner (60) in place with an elastic stocking (72); inserting the wearer's foot, unfitted liner (60) and elastic stocking (72) into shell (25) and allowing unfitted liner (60) to cool.

Title: Soi substrate fabrication
Inventor: SARMA KALLURI R
IPC: H01L21/762
Filed: 1994-06-30
Abstract: A back-etch silicon-on-insulator SOI process that has a silicon handle wafer with an oxide layer bonded at room temperature to a silicon device wafer with an etchstop and silicon device layer. The surfaces that are bonded at room temperature are first conditioned to be hydrophilic. After bonding, the edges of the layers are sealed. The silicon device wafer, the etch-stop layer and the device layer are boron doped. Most of the silicon device wafer is ground away. Then, the remaining portion of the silicon device wafer and the etch stop layer are chemically etched away, thereby leaving a uniform layer of silicon device layer on the oxide layer of the silicon handle wafer. Because the bonding, grinding and selective etching are performed at room temperature, inter-diffusion of the boron between the various layers is prevented and thus permits the selective etching process to result in a nearly perfect silicon device layer in terms of an even-surfaced, defect-free and thin layer on the buried oxide layer of silicon handle wafer. The resulting SOI wafer is then annealed at a high temperature, prior to device processing.
Patent CA-2166860-A1 (CA)
Inventor: SANCHEZ LUIS R
IPC: G01B7/28
Filed: 1993-07-19
Abstract: A mechanism (10) for scanning the contour of a tri-dimensional body (R) including control circuitry (120) for processing and storing the pattern data obtained. The contour pattern is measured by using contour follower members (92x) that radially slide between the two arms (108, 108') of a scan rotor assembly (100) that is driven by a reference step motor (102). Coaxially aligned phase disks (82x) are slidably mounted over outer slots (112x, 112x') on the outer periphery of the arms and a linkage mechanism (94x) is pivotally mounted on one end to a predetermined point (91x) in the phase disks and the other end (93x) to the contour follower member. The phase disks are slowed down by frictional force applied to the phase disks and this slowing down force is overcome by the contour follower once it comes in contact with the reference body. The phase angle difference between the phase disks and the referenced step motor rotation is measured, processed and stored for subsequent pattern matching with the use of a microprocessor.
