Abstract: A controller for a watercraft controls first and second marine propulsion devices to start moving the watercraft by setting a first default angle, a second default angle, and a default thrust ratio as a first target rudder angle, a second target rudder angle, and a target thrust ratio respectively when a desired motion of the watercraft is straight sideways movement. The controller determines at least one of a first correcting angle, a second correcting angle, and a correcting thrust ratio to reduce an error between the straight sideways movement of the watercraft and an actual motion of the watercraft. The controller corrects the first target rudder angle, the second target rudder angle, and the target thrust ratio with the first correcting angle, the second correcting angle, and the correcting thrust ratio, respectively. The controller repeatedly detects the error and repeatedly updates the correcting angles and the correcting thrust ratio.

The positioning protrusions are inserted in the positioning holes, and press the teeth against the base yoke inward in the radial direction such that the tooth-bottom surface is brought into contact with the tooth-hole-radial-direction-inner-end surface and the tooth-oblique surface is brought into contact with the tooth-hole-circumferential-direction-end surface.

Abstract: A joystick outputs an operating signal indicating a tilt amount and a twist direction of the joystick. A controller receives the operating signal and controls a marine propulsion device to output a thrust having a magnitude depending on the tilt amount. The controller changes a rudder angle of the marine propulsion device such that a watercraft turns in a direction corresponding to the twist direction. The controller reduces a speed of changing the rudder angle with an increase in the magnitude of the thrust.

Abstract: In a management device, a management storage unit stores management data in which suction position offset data, parameter information, and a processing state image are associated with each other, the management data being acquired from a mounting apparatus by a management communication unit. When a command to select one piece of parameter information from the various pieces of parameter information is input, a management control unit causes a management display unit to display a suction position offset distribution indicating distribution of a data group of the suction position offset data. Once this has occurred, when a command to select one or more specific position offset data from the data group of the suction position offset distribution is input, the management control unit causes the management display unit to display the processing state image corresponding to the specific position offset data simultaneously with the suction position offset distribution.

Abstract: In a management device, a management storage unit accumulates and stores management data in which suction position offset data, loading position offset data, and parameter information are associated with each other. A management control unit causes a management display unit to simultaneously display suction position offset distribution indicating distribution of a data group of the suction position offset data and loading position offset distribution indicating distribution of a data group of the loading position offset data. The management control unit controls the management display unit such that, when a command to select one or more specific position offset data from the data group of one position offset distribution is input, attention data corresponding to the specific position offset data is displayed in a different display mode from a display mode of residual data in the data group of another position offset distribution.

Abstract: The attachment possible period during which the attachment operation of the component supply reel can be performed is predicted for each of the tape feeders equipped in the component mounting apparatus, and the attachment time indicating a timing of the attachment operation is set to overlap the attachment possible periods of the candidate feeders, out of the tape feeders. Therefore, a frequency of the component replenishment operation of the operator can be suppressed. Further, the execution mode of the attachment operation for the candidate feeder corresponding to the attachment time is determined based on the number of the components planned to be supplied in accordance with the production planning by the candidate feeder. Therefore, a number of the components suitable for the production planning of the components-mounted boards can be replenished.
