Patent CA-2481834-A1 (CA)
Inventor: GRAF MICHAEL
IPC: H01L29/78
Filed: 2004-09-17
Abstract: A DMOS-transistor has a trench bordered by a drift region including two doped wall regions and a doped floor region extending along the walls and the floor of the trench. The laterally extending floor region has a dopant concentration gradient in the lateral direction. For example, the floor region includes at least two differently-doped floor portions successively in the lateral direction.      This dopant gradient in the floor region is formed by carrying out at least one dopant implantation from above through the trench using at least one mask to expose a first area while covering a second area of the floor region.

Title: Radio frequency gradient and shim coil
Inventor: UGURBIL KAMIL
IPC: A61B5/055
Filed: 2003-04-21
Abstract: A plurality of linear current elements (130B) are configured about a specimen to be imaged. A current in each current element is controlled independent of a current in other current elements to select a gradient and to provide radio frequency shimming. Each current element is driven by a separate channel of a transmitter and connected to a separate channel of a multi-channel receiver.  The impedance, and therefore, the current, in each current element is controlled mechanically or electrically.

Inventor: LARSON EDWARD ALAN
IPC: B26D3/26
Filed: 2005-03-17
Abstract: Disclosed are a method and a system for extruding, cut into strands, cooling, and chopping a ground food product. The system comprises a cooling unit, a conveyor belt urging the pieces through the unit, and a chopper for cutting the pieces exiting the unit. A cryogen source provides cryogen to the cooling unit. A feeder feeds the ground food product onto the conveyor belt adjacent an inlet of the unit. The feeder also extrudes the ground food product through a nozzle to place the stranded pieces onto the conveyor belt. A shear plate cuts the stranded pieces, while being extruded. A hydraulic system moves the shearing plate. The system is adapted to dispense cryogen to the cooling region at a rate sufficient to lower the temperature of the cut stranded pieces to a desired temperature when they exit the unit. A chopper cuts the extruded and stranded pieces immediately after freezing.

Title: Fluorochemical-containing textile finishes that exhibit wash-durable soil release and moisture wicking properties
Inventor: HAYES HEATHER J
IPC: D06M15/00
Filed: 2004-01-23
Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided.  Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties. The method of adherence to the target yarn, fiber, and/or fabric may be performed any number of ways, most preferably through the utilization of a jet dyeing system or through a steam-transfer method. The particular methods of adherence, as well as the treated textile fabrics and individual fibers are also encompassed within this invention.

IPC: G06T7/00
Filed: 2003-12-25
Abstract: There is provided an osteoporosis diagnosis support device using a panorama X-ray image. A digitized image of panorama X-ray photo is input to a personal computer (S210). On the panorama X-ray photo, a lower jaw bone molar portion lower edge cortical bone is specified by a mouse so as to be observed (S220).  The extracted image is subjected to the image processing as follows. (1) A  median filter is applied to the image and noise is reduced as much as possible. (2) A skeleton by the fine structure elements is obtained (S230).  (3) Only a component parallel to the inclination of the lower jaw bone lower edge is extracted (S240). (4) The image is digitized by using, for example, a linear judgment method by Mr.Otsu (S250). After this, the digitized lines are classified into three groups according to the size and the group of the smallest lines is excluded. If there is more than one line of the largest group, it is judged that there is a suspicion of osteoporosis (S260).
