Title: Outboard motor steering system
Inventor: TAKADA HIDEAKI
IPC: B63H20/08
Filed: 2003-05-30
Granted: 2006-10-03
Abstract: An outboard motor steering system wherein an electric motor is installed inside the outboard motor and the output of the electric motor rotates a swivel shaft to steer the propeller, thereby enhancing steering feel by using an electric motor to enable highly responsive and accurate control. In addition, the configuration is simple and does not lead to an increase in number of components or weight. In another steering system wherein a first hydraulic cylinder for driving a steering system and second hydraulic cylinders for driving a power tilt-trim system are supplied hydraulic oil from the same pump, thereby making a dedicated hydraulic pump for the steering system unnecessary and thus enabling reduction of system size and weight. In still another steering system wherein the outboard motor main unit is swiveled to turn the propeller by extension/contraction of the hydraulic cylinder whose one end is attached to the outboard motor main unit and other end is attached to the boat side of the outboard motor. In a plan view taken in the gravitational direction, moreover, the hydraulic cylinder is located inside the vertical projection plane of the profile of the outboard motor main unit, so that the hydraulic cylinder never projects outside the outboard motor main unit no matter how much it extends or contracts.

Abstract: La présente invention concerne un procédé pour concevoir des traitements à l'acide et sélectionner un traitement optimal pour une stimulation de puits. Selon cette invention, des caractéristiques du réservoir sont obtenues afin de sélectionner par la suite les données cinétiques réactionnelles sur les minéraux présentant un intérêt, le traitement appliqué au réservoir est mis à l'échelle par utilisation d'un modèle mathématique et des dommages en temps réels sont calculés sur la base de la pression au fond du puits et de la vitesse d'injection et sont comparés à ce qui était prévu, afin d'ajuster le traitement. Le modèle produit facilite l'optimisation des traitements matriciels en fournissant une estimation des diverses stratégies de traitement. Une stimulation avec des formules liquides non traditionnelles peut être facilement calculée. Les valeurs calculées peuvent ensuite être utilisées dans un modèle économique, afin de justifier les coûts supplémentaires qui sont associés à l'utilisation des liquides non traditionnels. Ce procédé peut être utilisé afin d'optimiser des traitements matriciels, mais peut également servir d'outil permettant de développer de nouveaux liquides, de prévoir et d'éliminer les incrustations et de tester la compatibilité des liquides.
