摘要： A rotor includes a rotor core configured by laminated steel plates and a magnet insertion hole extending along an axial direction of the rotor core, with a resin interposed between a permanent magnet placed in the magnet insertion hole and an inner wall face of the magnet insertion hole. In a manufacturing method for this rotor, in a first process, the permanent magnet and the resin are integrated together to manufacture a resin-coated permanent magnet. Next, in a second process, the resin-coated permanent magnet is press-fitted into the magnet insertion hole. Next, in a third process, the post-second-process rotor core is heated to a temperature that is at least the temperature at which the resin softens. Next, in a fourth process, the post-third process rotor core is cooled.

摘要： A flexible structure with a multi-joint function is formed by connecting flexing parts in which wave washers are stacked and welded to each other. The flexible structure includes a first flexing part, a second flexing part, and a connection part. The first flexing part and the second flexing part are capable of flexing and extending. The connection part is welded in an axial direction between the first flexing part and the second flexing part and has a rigidity higher than the first flexing part and the second flexing part. The first flexing part and the second flexing part each include wave washers stacked in the axial direction and welded to each other. The connection part has a circulating shape in which an inner circumference and an outer circumference are each continuous in a circumferential direction.

摘要： A watercraft maneuvering system includes an actuator having a function of generating a propulsion force of a watercraft and a function of causing the watercraft to generate a moment, an operation unit configured to receive an input operation of a watercraft operator, and a watercraft control device configured to operate the actuator. When the operation unit has received an input operation for stopping an operation of the actuator while the watercraft control device is operating the actuator, the watercraft control device operates the actuator without any need for the operation unit to receive the input operation for at least one function of the actuator generating the propulsion force in an opposite direction to a direction of an inertial force occurring in the watercraft and causing the watercraft to generate the moment in an opposite direction to a direction of a moment of inertia occurring in the watercraft.
