Abstract: PURPOSE: A driving device for a fixing device is provided so that paper can be easily removed without requiring a manual operation for releasing a heat roller and a pressing roller. CONSTITUTION: When a driving motor(10) is driven, a driving force is transmitted to a fixing device driving gear(20) through a gear train(11). A driving shaft(21) is rotated with the driving gear(20). Here, a spring clutch(41) is rotated in a winding direction. According to the rotation in the winding direction, the spring clutch(41) is wound around a hub of a vertical driving gear(30), thereby rotating the vertical driving gear(30) in an identical direction. The vertical driving gear(30) rotates a heat roller gear(6a), thereby driving a heat roller(6) and a pressing roller. When paper is jammed between the heat roller(6) and the pressing roller, a controller displays an error message "PAPER JAM" on a display window. When a user pulls the paper, the heat roller(6) and the pressing roller are rotated, and thus the vertical driving gear(30) is rotated. The rotation of the vertical driving gear(30) does not influence on the spring clutch(41). Thus, the driving gear(20) is not rotated. Accordingly, an entire driving load is not applied to the heat roller(6). As a result, the user can easily remove the jammed paper.

Abstract: PURPOSE: A ship rudder is provided to minimize energy loss caused by the non-symmetrical property of complex rotating current and to enhance the efficiency of the thrust of a ship by strongly rectifying the flow of fluid. CONSTITUTION: A rudder(100) is rotatively installed in the rear of a propeller. A head end having the almost same height as the rotary shaft of the propeller is divided into an upper portion(101a) and a lower portion(102a). The upper portion inclines in the inverse rotating direction of the propeller and the lower portion inclines in the right rotating direction of the propeller. Then, the upper portion and the lower portion are mutually twisted and combined together in the joined portion by a streamlined bulb(110). A noise portion(111) of the bulb is protruded forward within 40% of the length of the joined portion. A conic streamlined tail portion(112) is not protruded backward and the head end of the noise portion inclines in the right rotating direction of the propeller from the central line of the ship. Complex rotating currents in the right direction flows upward along the slant of a side face(110a) after the rudder inclines and the complex rotating currents in the inverse direction flow downward along the slant of a side face(110b). Thus, bulb resistance is minimized and the rear current speed of the propeller becomes faster, then a rectifying effect and the efficiency of trust by the rudder are maximized.
