Patent CA-2315626-A1 (CA)
Title: Mecanisme de reglage d'amortisseur
Inventor: NEWBOULD ANDREW PAUL
IPC: F16F9/44
Filed: 1998-12-23
Abstract: L'amortisseur faisant l'objet de cette invention comprend un piston (1), comportant un orifice (5) permettant le passage de fluide à travers le piston (1) entre une première face (14) et une seconde face (7). Une rondelle clapet (6) montée sur la seconde face (7) du piston, couvre l'orifice (5) et peut se déformer pour permettre au fluide d'amortissement de passer à travers l'orifice. Un moyen (4) est prévu pour plaquer par pinçage une surface de la rondelle clapet (6) contre la seconde face (7) du piston, ce moyen de pinçage étant réglable pour permettre l'augmentation ou la diminution de la surface de la rondelle clapée (6) qui est pincée. De préférence, la rondelle clapet (6) est généralement conçue en forme de disque et le moyen de pinçage (4) pince une surface de la rondelle clapet (6) avec un rayon effectif et ce moyen de pinçage est réglable pour modifier ce rayon effectif. En modulant la surface pincée de la rondelle clapet (6), la déformation de la rondelle est facilitée ou empêchée, ce qui règle les caractéristiques d'amortissement du fluide passant à travers l'orifice (5). Ainsi, seule une force modérée et uniforme est nécessaire pour moduler la surface de pinçage, ce qui évite les dommages au mécanisme et permet une réaction linéaire et reproductible de la part du mécanisme de réglage.

Title: Liquid treating process and apparatus, as well as liquid treating system
Inventor: MORI TOSHIKAZU
IPC: C02F9/00
Filed: 1998-11-20
Abstract: A method of treating a liquid which comprises hydrophobizing colloidal particles in a stable hydrated state or a metastable hydrophobic colloidal state in the liquid with an electric field formed by a microwave to separate them from molecules of the liquid, colliding the separated colloidal particles with each other by the action of cavitation caused by low-frequency ultrasonics to coagulate the particles, and deodorizing the liquid with highfrequency electromagnetic ultrasonics. Thus, the colloidal particles dissolved in the liquid can be easily removed without fail and the liquid can be deodorized without the need of large-scale facilities. Specifically, a liquid containing colloidal particles of water-soluble organic substances, microorganisms, etc. is treated by applying a microwave to the liquid to separate the colloidal particles from molecules of the liquid, then applying low-frequency ultrasonics to the resultant mixture to coagulate the colloidal particles, and finally applying high-frequency electromagnetics ultrasonics to the liquid to deodorize the same.

Title: Method and apparatus for providing depth blur effects within a 3d videographics system
Inventor: YASUMOTO YOSHITAKA
IPC: G06T15/40
Filed: 2000-08-21
Abstract: Efficient techniques for blurring an image based on depth within a 3D graphics system allow an artist or programmer to specify one or more depth thresholds. Pixels having depths that are further away than a particular depth threshold are blurred more than pixels having depths that are closer than the depth threshold. Efficient summing/averaging techniques can be used to blend a variable number of neighboring pixel colors (the number of pixels blended being selected based on pixel depth) to provide depth-based blur. An enhancement blends only those pixels that are further away than the.target pixel. Using such techniques, display surfaces that are further away from the viewpoint appear blurred and less distinct than surfaces that are closer to the viewpoint. The resulting visual effects can efficiently create more realistic images for a number of applications such as, for example, driving games, games in which a character travels progressively along a path, etc.
Patent CA-2316950-A1 (CA)
Inventor: ASAI KOHTARO
IPC: H04N21/6332
Filed: 1999-07-16
Abstract: An image decoding device performs expansion processing and reverse orthogonal conversion in fixed block units with respect to image compression data.   The image decoding device is provided with an error block detection section which receives a threshold value and an image signal in frequency bands. The error block detection section determines whether or not an error is contained in block data based on the threshold value and the image signal in the frequency domain and outputs a detection state in the block data. Also, provided is an image encoding device for dividing image data into block units, performing orthogonal conversion and compression coding on each block unit. The image encoding device receives a threshold value and an image signal in a frequency domain and outputs an image signal with an added limit in a frequency domain based on a predetermined threshold value and an image signal in a frequency domain. It outputs encoded, compressed image data with the limit imposed. obtained as a result of encoding the received image signal.
Patent CA-2317374-A1 (CA)
Title: Trailer having actuatable tail ramp
Inventor: LANDOLL DONALD R
IPC: B60P1/43
Filed: 2000-09-05
Abstract: The trailer has a deck assembly that includes a level main deck portion and a tail hinged to the main deck for vertical swinging movement between a level transport position, a downwardly and rearwardly inclined ground-loading position, and an upwardly and rearwardly inclined dock-loading position. Raising and lowering of the tail between such positions is carried out by fore-and-aft movement of the shiftable undercarriage of the trailer, such undercarriage being located under the tail and generally behind the hinge when the trailer is in its roading position with the tail in its transport position. When the undercarriage is shifted forwardly beyond a lost motion segment of travel, the tail is allowed to progressively descend by gravity to its ground-loading position. Returning the undercarriage to its roading position beneath the tail causes the tail to be raised back to its transport position. If the tail is to be raised to dock height, the undercarriage is pulled forwardly until the forward termination of its lost motion segment of travel is reached, whereupon an air bag is actuated to elevate a lifting strut member into an enabled position in contacting engagement with the underside of the tail. Thereafter, rearward movement of the undercarriage causes the lifting strut member to push the tail upwardly to the dock-loading height and to hold the tail at such position. To lower the tail back to its transport height, the undercarriage is shifted forwardly and the air bag is deflated, lowering the strut member back to its disabled position and allowing the tail to become once again fully supported by the undercarriage. When the undercarriage is thereafter returned to its rearmost roading position, the trailer is ready for travel. Only one hydraulic cylinder is required for carrying out the tail actuation, together with an air bag actuator when raising of the tail to dock height.

Patent CA-2333683-A1 (CA)
Inventor: HECKEL DONALD T JR
IPC: F16H25/24
Filed: 1999-05-28
Abstract: A threaded leadscrew (16) moves axially within the housing (12) of a linear actuator (10). The leadscrew's movement rotates a threaded gear nut (18) that surrounds the leadscrew. Stopping the gear nut rotation prevents leadscrew translation. The locking mechanism for selectively blocking rotation of the gear nut (18) includes a cam mounted on the housing (12), which connect remotely to a user actuated handle. A lever (90), which mounts on the cam, has a tooth movable between adjacent teeth on the gear nut (18). The cam (50) also has a blocker that engages the lever. When the cam (50) is in the closed position, the blocker prevents the lever from moving to its released position away from the gear nut's teeth (22). When the cam (20) is moved to the released position, the blocker releases the lever (90) and allows it to move away from the gear nut (18). The lever has an opening (102) that is somewhat bigger than a pin (104) on the cam that extends into the opening. When the pin reaches one surface of the opening, it pulls the lever out of its engaged position. However, before the pin reaches that position, the blocker on the cam has already disengaged the lever. Therefor further movement of the cam pulls the lever out of engagement with the teeth (22) on the gear nut (18), and the blocker on the cam (20) is not positioned to prevent that movement.
