A cell handling apparatus includes: a first plate including a first cell containing portion capable of containing a cell; a second plate including a second cell containing portion capable of containing a cell; a head that sucks a cell from the first cell containing portion, discharges a sucked cell to the second cell containing portion, and transfers a cell between the first plate and the second plate; and a recognition processing unit that recognizes a cell in the first cell containing portion and the second cell containing portion. The recognition processing unit performs processing of assigning a first identification code for recognizing a first cell contained in the first cell containing portion, a second identification code for recognizing the first cell transferred to the second cell containing portion, and cooperation information for associating the first identification code and the second identification code.

A watercraft battery management system includes a charge level sensor (71) to detect a charge level of a watercraft battery (40) mounted on a watercraft (51), a power supply request transmitter (72, 73) to transmit a power supply request when the charge level of the watercraft battery (40) detected by the charge level sensor (71) is within a predetermined low charge level range, and a power supply request receiver (5, 24) to receive the power supply request transmitted by the power supply request transmitter (72, 73). A battery monitoring kit provided on the watercraft (51) may include the charge level sensor (71) and the power supply request transmitter (72, 73). The power supply request receiver (5, 24) may be mounted on a vehicle (1) including a power supply device (90) to be used to charge the watercraft battery (40).

A cell handling apparatus includes: a container; a camera; a head; and a correction control unit. The container includes a translucent and shape-deformable bottom surface that holds a cell, and a state checking portion for recognizing the shape deformation. A tip is attached to the head and the head executes an operation of approaching the bottom surface from above to suck a cell on the bottom surface and an operation of discharging a cell toward the bottom surface. The correction control unit is configured to correct position coordinates of the head. The correction control unit is configured to detect contact of a tip end of the tip with the bottom surface based on a state change of the state checking portion in an image of the bottom surface captured by the camera.

The boat propulsion device includes a propeller, an electric motor, a controller, and a communication device. The electric motor rotates the propeller. The electric motor includes a rotor including permanent magnets, and a stator that includes a plurality of coils arranged along a rotation direction of the rotor and that faces the rotor in a radial direction of the rotor. The controller controls driving of the electric motor. The controller includes a memory. The communication device communicates with an external device. The controller receives a correction request from the external device via the communication device, and rewrites correction values of electrical angles of current flowing through the plurality of coils, which are stored in the memory, based on the correction request.

A cell recognition apparatus includes: a cell containing portion capable of containing a cell; an imaging unit configured to image the cell containing portion; and a recognition processing unit configured to recognize a cell in the cell containing portion based on an image acquired by the imaging unit. The recognition processing unit performs processing of assigning a first identification code for recognizing a whole cell contained in the cell containing portion, a second identification code for recognizing a cell element included in the whole cell, and cooperation information that associates the first identification code with the second identification code.

An outboard motor comprises a steering shaft, a base, a cowl, a drive unit, a winding member, and an electric cable. The base rotatably supports the steering shaft. The drive unit includes a propeller and an electric motor. The drive unit is rotatable together with the steering shaft. The winding member is connected to the steering shaft. The winding member is rotatable together with the steering shaft. The winding member includes a winding shaft that extends in the axial direction of the steering shaft. The electric cable is connected to the electric motor. The electric cable extends from the electric motor to inside the cowl. The electric cable is wound around the winding shaft.

An electric boat propulsion device includes a cylindrical duct; a propeller rotatably supported inside the duct, the propeller having blades arranged around a propeller axis extending along a central axis of the duct, and a cylindrical rim surrounding the blades; and an electric motor that rotates the propeller relative to the duct, the electric motor having a stator provided on the duct and a rotor provided on the rim. The duct has an accommodation space, and an inner wall constituting the accommodation space includes a conductive wall. The electric boat propulsion device further includes a circuit board including a contact region that contacts the conductive wall and a non-contact region separated from the conductive wall, the circuit board having a detection sensor that outputs a signal corresponding to a rotation angle of the rotor, and a circuit pattern formed in the non-contact region so as to avoid the contact region.

There is described a straddled vehicle wherein high stress is unlikely to be generated at the mounting portion of the fuel pump unit during acceleration and deceleration, and it is possible to reduce the size of the bottom portion of the fuel tank; the straddled vehicle is a motorcycle including a fuel tank (20) having a front wall (21), a pump bracket (30) mounted on the front wall (21), and a fuel pump unit (50) mounted on the pump bracket (30) and arranged inside the fuel tank (20); the fuel pump unit (50) including a filter unit (52) through which fuel is sucked in, a unit lower portion (54) extending upward from the filter unit (52), a unit upper portion (56) extending forward from the unit lower portion (54) and connected to the pump bracket (30); and a pump (55A, 55B) provided in the unit lower portion (54) or the unit upper portion (56).

A straddled vehicle includes a pair of left and right retractable footboards. The pair of left and right retractable footboards are: disposed forward of a pair of left and right main footrests; members different from the pair of left and right main footrests; and configured to allow a main rider who is driving the straddled vehicle to place his/her feet thereon instead of on the pair of left and right main footrests while sitting on a main rider seat. The pair of left and right retractable footboards each include a main rider foot placement surface configured such that the main rider who is driving the straddled vehicle places his/her feet thereon while sitting on the main rider seat, and are each configured to be able to maintain two stable stationary states. The straddled vehicle is capable of improving the degree of freedom of a foot placement position at which a main rider places his/her foot while driving the straddled vehicle; improving the footing of the main rider; and improving the visibility of the main rider's foot and therearound.

An electric boat propulsion device includes: a rotor having a rotation shaft; a stator core; windings wound around the stator core; a motor control circuit; and a connecting member having a conductor electrically connecting the windings and the motor control circuit, the connecting member being arc-shaped along the circumferential direction of the rotation shaft.
