  • Patent number: 10189552
    Abstract: A ship propulsion device (1) is adapted to rotate a propeller (20) to propel a ship (2). In a case where the rotating speed of the propeller (20) is less than a predetermined rotating speed, a low-output sub-motor (M2) is controlled and rotationally driven by a small-capacity general-purpose inverter (24), and the rotational driving is transmitted to the propeller (20) so as to rotate the propeller. In that case, in a drive system of a main motor (M1), rotation is not transmitted to a slip clutch (23) or an input shaft (7) by cutting off an on-off clutch (8). In a case where the rotating speed of the propeller (20) becomes equal to or more than the predetermined rotating speed, a driving source is switched from the sub-motor (M2) to the main motor (M1) so as to couple the on-off clutch (8), and the rotating speed of the main motor (M1) is controlled by the slip clutch (23) and transmitted to the propeller (20) so as to rotate the propeller (20).

  • Patent number: 9133277
    Abstract: Provided is a method for solubilizing cellulose in which cellulose can be solubilized in a short period of time with a low amount of excess decomposition and without the use of a catalyst or other chemicals. A starting material containing cellulose is pulverized to reduce the crystallization thereof, adjusted for moisture content, reacted with water in the absence of a catalyst, and converted into a water-soluble component. At this point, the reaction is performed at a temperature of 100° C. or more and less than 300° C., and a total pressure of 0.05 MPa or more and less than 10 MPa. Water is added and extracted from the water soluble component, and solid-liquid separation is performed to separate the solids and the aqueous solution.
