Abstract: An autonomous vehicle with a reduced risk of collision during conveyance is provided. The autonomous vehicle docks with a conveyance target and conveys the conveyance target. The autonomous vehicle includes a docking mechanism configured to dock with the conveyance target, a sensor configured to acquire object position data related to a position of an object within a measurement range, and a controller configured to control, based on the object position data acquired from the sensor, the conveyance performed by the autonomous vehicle docked with the conveyance target. The measurement range of the sensor includes at least an area above the autonomous vehicle.

Abstract: A non-positive displacement type pressurizing device for pressurizing a fluid includes a rotor including a rotary blade row including a plurality of rotary blades provided at intervals in a circumferential direction; a casing that accommodates the rotor; a stationary blade row supported by the casing and including a plurality of stationary blades provided at intervals in the circumferential direction; and a plurality of heat exchanging units for cooling the fluid, wherein the heat exchanging units are configured to divide a flow path formed between stationary blades, of the plurality of stationary blades, adjacent to one another in the circumferential direction in a height direction of the stationary blades.

Abstract: An actuator for a movably supported object, comprising a rack, a rotatable pinion engaging the rack, a biasing member disposed around the axis of the pinion and connected to the pinion, and a damper. The biasing member stores a biasing energy while the pinion is rotated in one direction by a movement of the rack in a first direction. The biasing member biases the pinion in the other direction with the stored biasing energy and thereby biasing the rack in a second direction opposite to the first direction. The damper is encircled by the biasing member and has a fluid chamber which contains a viscous fluid and is formed around the axis of the pinion. The damper further includes a rotary member which is rotated with the pinion and has a damper portion disposed in the fluid chamber. The viscous fluid provides a resistance to rotation of the damper portion and to rotation of the pinion in the above-indicated other direction. Also disclosed is a container device incorporating the actuator.
