  • Publication number: 20210331777
    Abstract: There is provided a ship maneuvering system including: a turning operation device configured to output a turning operation signal corresponding to a turning operation; a turning control device configured to change a direction of each of ship propulsion machines based on the turning operation signal; an output operation device configured to output an output setting signal indicating an output of a power source of each of the ship propulsion machines set by an output setting operation; and an output control device configured to increase or decrease the output of the power source of each of the ship propulsion machines based on the output setting signal. When the turning control device fails, the output control device turns a ship by making outputs of power sources of the ship propulsion machines different from each other based on the turning operation signal.

  • Patent number: 10279880
    Abstract: Disclosed is an control device of an outboard motor, including: a computation unit configured to set, as a starting point, a timing before a gearshift mechanism is shifted from forward to neutral after an accelerator opening level is fully closed in a case where an operator's manipulation is performed from forward to neutral, and compute a time-series change of an engine rotation speed as a simulated ship speed on the basis of the engine rotation speed detected by an engine rotation speed detector at the starting point; and a control unit configured to control an actuator such that, in a case where the operator's manipulation is performed from forward to reverse through neutral, the gearshift mechanism is maintained in the neutral position until the simulated ship speed estimated by the computation unit becomes a predetermined threshold value or lower, and is then shifted to reverse.

  • Publication number: 20030200898
    Abstract: A non-asbestos friction material is made by molding and curing a composition primarily comprising a fibrous base excluding asbestos, a binder, a filler, and at least three metal sulfides excluding titanium sulfide, complex metal sulfides and being free of antimony and lead compounds. This friction material has minimized metal catch and improved wear resistance, both in the high-temperature region. Absent lead and antimony compounds, the friction material is friendly to the environment.
