Abstract: A control device includes a controller that executes determining a connection between a first unit that has a boarding space which allows a user to board and is provided with a predetermined facility and that is provided with a first path through which a fluid used in the predetermined facility passes and a second unit that is configured to be separated from and connected to the first unit and that has a drive device of a vehicle that is formed by being connected to the first unit, and supplying the fluid in the first path to a second unit side to absorb heat generated from the drive device.

Abstract: Provided is a multi-tube nozzle for use in eradicating harmful aquatic organisms, which physically kills harmful aquatic organisms while feeding water and thus allows intake water to be fed directly into a culture tank or a ballast tank without the need for a pretreatment tank, chemicals, neutralizers, etc. A multi-tube nozzle (A) for use in eradicating harmful aquatic organisms includes at least three nozzle tubes (1) that are provided adjacent to each other. The nozzle tubes (1) each includes: an inlet-side opening section (2) having an inner diameter that decreases from an inlet opening toward a throat section (3) located in the middle of the tube; an outlet-side opening section (4) having an inner diameter that increases from the throat section (3) toward an outlet opening; and the throat section (3) having a smallest inner diameter. The adjacent nozzle tubes (1) are spaced apart by a distance such that the adjacent inlet-side opening sections (2) overlap each other.
