  • Publication number: 20250145384
    Abstract: A support mechanism which permits the displacement of an end surface of a movable linear conveyor toward a side in the X direction. The support mechanism supports the end portion of the movable linear conveyor with respect to the end portion of the fixed linear conveyor while having the interval between the end surface of the movable linear conveyor positioned at the facing position or the facing position and the end surface of the fixed linear conveyor in the X direction. Thus, since the interval is between the end surface of the movable linear conveyor and the end surface of the fixed linear conveyor by the support mechanism supporting the movable linear conveyor with respect to the fixed linear conveyor, it is possible to reliably form the interval therebetween. Therefore, it is possible to absorb the displacement of the released end surface.

  • Publication number: 20250147492
    Abstract: A management device of a component mounting system includes a management storage unit, a calculation unit, and a data generating unit. The management storage unit stores management data in which processing state data is associated with each piece of production factor information that identifies each production factor used in production of a component loading board. The calculation unit calculates normal processing rate data of normal suction rate data or normal loading rate data based on a data group of the management data from a prescribed time point to a current time point. The calculation unit outputs a normal processing rate data set indicating a data group of the normal processing rate data for each use time point. The data generating unit generates predicted normal processing rate data subsequent to the current time point according to a change in a use variable based on the normal processing rate data set.

  • Patent number: 12275493
    Abstract: A control device sets a second electricity control switch in an intermediate state in a process of switching a discharge battery for supplying a drive unit with an electrical current from a first battery to a second battery. Subsequently, when a comparative relationship between an electric potential of a smoothing capacitor and an electric potential of the second battery fulfills an intermediate state termination condition, the control device sets the second electricity control switch in a bidirectional conduction state. The intermediate state is when an electrical current flowing from the second battery to the drive unit is allowed, and an electrical current flowing from the drive unit to the second battery is inhibited. The bidirectional conduction state is when both of the electrical current flowing from the second battery to the drive unit and the electrical current flowing from the drive unit to the second battery are allowed.

  • Patent number: 12258112
    Abstract: A system includes an outboard motor, a lift actuator, a sensor, and a controller. The sensor detects motion information indicating an up-and-down directional motion of a bow of a watercraft. The controller is configured or programmed to selectively set either a lift-up direction or a lift-down direction as a lift direction in accordance with the up-and-down directional motion of the bow based on the motion information. The controller is configured or programmed to control the lift actuator to cause the outboard motor to perform the lift motion in the lift direction, and set a duration of the lift motion to be different between when the outboard motor is caused to perform the lift motion in the lift-up direction and when the outboard motor is caused to perform the lift motion in the lift-down direction.
