An electric propulsion machine (1) includes an electric motor (6), an electric motor control circuit (51), a propulsion mechanism (4) to generate thrust from an output of the electric motor, and a battery unit (20) to supply electric power to the electric motor. The battery unit (20) includes a mode-setting manipulation element to accept a designation of an operating mode. The electric motor control circuit (51) outputs a control signal for controlling the electric motor based on an operating mode which is designated from among plural operating modes.


A cellulose fiber can reduce environmental burden while providing an enhanced modulus of elasticity easily and reliably. A composite material contains the cellulose fiber. A method of producing the cellulose fiber includes preparing a solution where needle-shaped phases each comprising a cellulose I crystal structure are dispersed in a matrix phase comprising a cellulose II crystal structure. The cellulose fiber includes the matrix phase and the needle-shaped phases contained in the matrix phase and the needle-shaped phases are oriented along an axial direction.


A boat maneuvering control method for a boat (1) provided with a propulsion device (3) includes acquiring a target orientation, acquiring the actual orientation of the boat, setting a target yaw rate value based on orientation information of at least one of the target orientation and the actual orientation, detecting the actual yaw rate value of the boat, and controlling the direction of the thrust force of the propulsion device based on the target yaw rate value and the actual yaw rate value.


A pouring cup position detection system (100) includes an image processing device (10) including an imager (12) which moves relative to the mold (M); and at least one marker (20) provided on the mold and positioned relative to the pouring cup (1g). The imager captures an image containing at least one marker. Based on the image captured by the imager, the image processing device generates information concerning the position of the pouring cup.


A driving assist method includes detecting positional information of a first vehicle, storing the detected positional information, detecting a curve along which the first vehicle travels in accordance with the stored positional information, generating curve information including a curvature of the curve at the detected curve, transmitting the generated curve information from the first vehicle after the first vehicle passes the curve, receiving the curve information by a second vehicle, determining a timing to provide the curve information in accordance with the received curve information, and providing the curve information at the determined timing.
