Abstract: A heat exchanger causes heat exchange between water and a refrigerant. The heat exchanger includes a first flow path through which the water flows, and a second flow path through which the refrigerant flows. A fragile portion is formed by any one of members forming the first flow path other than a partition wall partitioning the first flow path and the second flow path or any one of joining portions where members forming the first flow path are joined to each other. The fragile portion has a lower strength than the other members forming the first flow path.

Abstract: A control system includes an imaging unit that acquires an image of a plane including a target, an actuator that provides physical action to the target, and a control unit that controls the actuator. The control unit includes a setting unit that uses a relationship between four or more different position coordinates on the plane and directions of the actuator corresponding to the four or more different position coordinates to set a transformation characteristic of transformation of any position coordinates on the plane into a direction of the actuator. The control unit includes an adjustment unit that uses position coordinates of the target on the plane and the transformation characteristic to adjust the direction of the actuator so that the physical action is provided to the target.

Abstract: A vortex ring generation device includes a casing having a gas passage and a discharge port, and an extrusion mechanism that extrudes a gas in the gas passage such that the gas in a vortex ring shape is discharged from the discharge port. V (m3) represents an extrusion volume, D (m) represents a diameter of the discharge port, L (m) represents a length of a cylinder having the diameter D and the volume V, and Re represents a Reynolds number of the discharged gas. 500≤Re≤3000 and 0.5≤L/D≤2.0.

Abstract: In a heat exchanger, a fluid flows in a first direction between a first opening and a second opening. The heat exchanger includes a member forming N flow path regions arranged adjacent to each other along the first direction between the first opening and the second opening. N is an integer of 2 or more. Each of the N flow path regions includes a flow path through which the fluid flows. A first flow path region and an N-th flow path region are different from each other in number and cross-sectional area of the flow paths. The first flow path region is one of the N flow path regions located to be closest to the first opening in the first direction. The N-th flow path region is one of the N flow path regions located to be N-th closest to the first opening in the first direction.
