Abstract: A multicopter includes: motors to respectively rotate three or more rotors; and a radar system to transmit and receive a signal wave and detect a target by using the signal wave. An object detection apparatus in the radar system transmits and receives a signal wave to perform a target detecting process.

The signal wave received at the antenna element is inclusive of a target-originated reflected wave reflected off a target and a rotor-originated reflected wave. The apparatus determines whether or not a frequency band satisfying a predefined condition for identifying a frequency peak is contained in a frequency spectrum of the signal wave as received by the antenna element, and determines a peak of a frequency band satisfying the predefined condition to be a frequency of the target-originated reflected wave.

Abstract: Under a reduced-pressure environment, stopping at will liquid that flows out from a nozzle tip, or dispensing liquid with the level of energy at which it will not splatter has proven difficult. To address such difficulties, parameters including nozzle bore, and surface tension and viscosity of, and delivery pressure on, a liquid are selected so that the surface tension that acts on the liquid when flowing out from the nozzle tip will be greater than the momentum of the liquid. By dispensing liquid under such conditions, outflow of the liquid is reliably controlled, and rapid infusion work is realized.

Abstract: To effectively prevent uneven wear of a moving mover 70 and to stabilize the control characteristics by a valve. Rotation force is exerted to the mover 70 by the fluid flowing from the first chamber to the second chamber, or vice versa, which are formed at the opposite ends of the mover 70. With respect to a flow passageway 110 formed within an anchor 72 and for allowing passage of the fluid therethrough, there are provided a passageway portion 111 which is disposed along the axial direction and another passageway portion 112 which crosses the axial direction. By this, rotation force is generated at the time the fluid passes from the former passageway portion 111 to the latter passageway portion 112 (or vice versa) which crosses the axial direction.
