Title: Moulding for window of vehicle
Inventor: TOKUI TAKESHI
IPC: B60J1/02
Filed: 1997-07-15
Granted: 2005-05-10
Abstract: To prevent abnormal sounds made by the vibration of the tip of a seal lip of a moulding for a window of a vehicle which sounds are created when air is sucked out from an inner cavity by the difference in pressure between the inside and the outside of the seal lip when the vehicle operates at high speed, a seal lip body 4a extends in the direction of a vehicle body panel P from the leg of the moulding 1 for a window and a folded-back lip 4b is continuously integrally formed such that it is folded back in the opposite inward direction from the tip of the seal lip body 4a into the cavity 5 between itself and the vehicle body panel P and extends along the vehicle body panel P. When the vehicle is operated at high speed, even if the seal lip 4a is moved up by the difference in pressure between the inside and the outside of the seal lip body 4a, the folded-back lip 4b remains pressed against the vehicle body panel P and thus prevents the leakage of air from the cavity 5. Therefore, it can prevent the abnormal sounds which occur when the air leaks out.

Abstract: A color sorting machine sorts particles of different colors from raw material such as cereal grains or the like.  The machine has a down chute descending towards a front side of the machine for letting raw material particles flow down linearly, a photoelectric detection device which subjects the raw material particles jumped out of the down chute to light and discriminates different-color particles in accordance with difference in reflected light, and a nozzle device which injects air to and blows off the different-color particles.  The injection nozzle device is situated on the rear side of the machine with respect to a coming-down locus of raw material particles from the down chute and close to the coming-down locus.  The sorting machine further comprises a dust collecting device which is situated on the front side of the machine with respect to the coming-down locus of the raw material.  The dust collecting device has a dust collection opening which is substantially opposite to the injection nozzle device with the coming-down locus interposed therebetween, sucks in and discharges dust scattered from the raw material.  The color sorting machine is highly precise in sorting different-color particles and facilitates cleaning of the dust collecting device.

Abstract: Le mécanisme d'hypertension qui suit le blocage aigu de la NO synthase se traduit par une vasoconstriction induite par l'endothéline. Donc, NO semble inhiber l'activité de l'endothéline par le blocage de son expression et non par l'action directe d'un vasodilatateur chronique. L'administration d'un antagoniste de l'entodhéline à un patient présentant un état physiologique "normal" peut entraîner une vasodilatation régionale spécifique. Ce traitement s'avère être utile pour traiter la dysérection.

Abstract: Description d'une méthode permettant d'améliorer une image numérique. A la base, l'image est représentée sous forme de donnéees numériques, indexées pour représenter des positions sur un dispositif d'affichage. Les données numériques indiquent une valeur d'intensité Ii(x,y) pour chaque position (x,y) dans chaque i-ème bande spectrale. On ajoute la valeur d'intensité pour chaque position dans chaque i-ème bande spectrale afin de générer une intensité de valeur ajustée pour chaque position dans chaque i-ème spectrale, selon l'équation (I), où S est le nombre des bandes spectrales uniques incluses dans lesdites données numériques, où Wn est un facteur de pondération et où "*" désigne l'opérateur de convolution. Afin d'améliorer des aspects de l'image numérique tels que la compression de la plage dynamique, la stabilité chromatique et le rendu de luminosité, chaque fonction d'entourage Fn(x,y) est mise à une échelle unique. La valeur d'intensité, ajustée en fonction de chaque position dans chaque i-ème bande spectrale, est filtrée à l'aide d'une fonction commune avant d'être présentée au dispositif d'affichage. Pour les images en couleur, on introduit une nouvelle étape de restauration des couleurs, qui permet d'obtenir une image en des millions de couleurs qui se rapproche de celle perçue par l'oeil humain.

Granted: 2000-08-15
Abstract: A microprocessor controlled grill apparatus for simultaneous two-sided cooking of food items. The grill apparatus includes a stationary lower cooking platen, and an upper cooking platen which is raised and lowered by a unique linear actuator. This actuator provides for two distinct types and phases of movement The upper platen is lowered from its uppermost, angled open position first by an arcing movement which rotates the rear edge of the upper platen about a slide or thrust bearing and arcs the front edge of the upper platen downward until the upper platen is substantially parallel to but raised, or floating, above the lower platen and uncooked food. Next, the linear actuator lowers the upper platen toward the food, while keeping the upper platen horizontal and parallel to the lower platen. The microprocessor control of this apparatus allows the gap between the upper and lower platens to be calibrated to an extremely fine degree, which may be fixed or varied for preset cooking cycles for various standardized menu items, stored and accessed automatically.
