Abstract: L'invention porte sur une bande utilisée pour la coulée en continu de métaux et son procédé de fabrication. La bande, tout d'abord soumise à un traitement thermique, trempée, puis revenue pour en améliorer la résistance et en réduire l'étirabilité, est ensuite traitée pour produire à sa surface des irrégularités qui favorisent l'uniformité du transfert de la chaleur et permettent la collecte des gaz de surface, puis soumise à un deuxième traitement thermique dans des conditions régulées pour la recouvrir d'une couche d'oxyde réduisant l'adhérence entre la bande et le métal qui y est déposé.

IPC: G06T19/00
Filed: 1998-11-10
Abstract: A frame of still picture data is captured at an instant specified by a user from video signals supplied from a given video source, such as a television receiver, a video camera, etc., and the image data is displayed.  When the user specifies an area of image to be cut out from the displayed still picture, the image data in the specified area is cut out and recorded as a cutout image.  Each cutout image recorded is displayed in the form of an icon.  When any of the icons is selected by the user, the corresponding cutout image data is read and pasted in a part to be changed in the original image data.  Thus an image can be easily created by user's choice.
Patent CA-2253828-A1 (CA)
Inventor: TARTAGLIONE JOHN J
IPC: B24B33/08
Filed: 1997-04-17
Abstract: An elastomeric mount or band is provided for circumferential placement about a bonded abrasive segment of the type generally used to form a segmented grinding wheel assembly of a rotary surface grinder. The band serves to cushion the segment relative to a chuck of the grinder. The band is provided with a predetermined original or untensioned circumference and is elastically deformable or stretchable to a larger cirumference within a predetermined range of circumferences. This ability to elastically deform facilitates installation onto the segment and enables a single band to be used in combination with segments of various sizes. The band is preferably installed over a segment having a circumference greater than the band's original circumference so that tension in the installed band serves to mechanically fasten the band in position thereon. This mechanical fastening enables a user to easily move the band to various locations on the segment as desired.

Title: Satellite based earth fixed cell tracking method
Inventor: SCAINI CARMELO
IPC: H04B7/204
Filed: 1999-03-18
Abstract: The invention relates to rotating antenna feed structures and shaped reflector antennas to be used on satellites for uplink-downlink uses. The rotating antenna feeds, mounted on a device reminiscent of a wheel or roller, rolling in the direction of motion of the satellite, provide a multiplicity of spot beams.      The shaped reflectors remove the distortions caused by the shape of the earth and the orbit geometry. These distortions include an hour-glass shaped distortion due to the intersection of a conical scan with the Earth's surface and a variable speed distortion due to the differing propagation geometry as the beams rotate beneath the satellite. Removal of a varying cross-orbit velocity, due to the 24 hour per day rotation of the Earth, is accomplished with varying yaw rotations of the satellite.

Patent CA-2269298-A1 (CA)
Inventor: SVILANS MIKELIS NILS
IPC: H01L31/0352
Filed: 1999-04-16
Abstract: A photodetector has an extended wavelength range combined with high responsivity and reliability. It includes an active region having alternating compressive and tensile strain layers arranged so that the total effective strain of the active region is balanced. The thickness of each layer is limited so that a product of a thickness by strain is not exceeding about 20%nm to avoid formation of crystalline defects. The layers with higher optical absorption constant are made thicker than the layers with lower absorption constant to provide the required responsivity of the detector. In one embodiment, the active region is formed on InP substrate and includes alternating 0.25% compressive strain and 1.03% tensile strain layers of InGaAs composition, the compressive strain layers being approximately four times thicker. In another embodiment interfaces between the layers are compositionally graded. The described structure of the active region may be used in various types of photodetectors, e.g., PIN, APD, MSM, Shottky barrier and waveguide photodetectors. Depending on the materials used, the photodetector is capable of operating in a wide wavelength range, e.g. up to 2200 nm, and covering a wide range of temperatures, including cryogenic temperatures.
