Abstract: One or more propulsion arrangements for water vessels, and in particular propulsion arrangements that include flanking rudders with bidirectional high-lift sections to improve performance, particularly in the reverse direction. The flanking rudders are positioned adjacent a propulsor for directing a slipstream flow when the vessel is travelling in the reverse direction. Each flanking rudder has an elongated profile extending from a first edge to a second edge, and in which each elongated profile has a first bulb portion, a convex middle portion, and a second bulb portion.

Abstract: The present invention relates to an extended search word selection system and method, which provides related words associated with a search word of a user to select an extended search word.

Abstract: A bundle database management system comprises a search server including a bundle definition unit for defining a core word and a relevant word connected to the core word, and connection relation between the core and relevant words to generate and store bundle data; a description definition unit for defining description data corresponding to the core and relevant words; a search request receiving unit for receiving a search request including a specific search word input by a user; a search result page generating unit for generating a search result page including the bundle data retrieved by the search word as a core word and the description data retrieved by the core word; and a search result page transmitting unit for transmitting the search result page to the user; and a user terminal connected to the search server for transmitting the search request and receiving the search result page.

Abstract: A cam holder for supporting an end of a guide shaft for an optical pickup of an optical disk player with a cam groove used to adjust a tilt of the guide shaft. The cam holder includes an upper cam element, which is mounted on a main base, is capable of rotating, and forms a top surface of the cam groove along its circumference; and a lower cam element, which is coupled to the upper cam element, and forms a bottom surface of the cam groove along its circumference so that the top surface opposes the bottom surface of the cam groove. A hook is formed at an upper part of the lower cam element, and a step is formed at a lower part of the upper cam element so that the hook engages the step when coupling the lower cam element to the upper cam element.
