An electric apparatus and a control method thereof The electronic apparatus including a housing; a first door rotationally arranged on one side of the housing; a second door rotationally arranged on the other side of the housing; a first motor operationally connected to the first door; a second motor operationally connected to the second door; a first motor driver electrically connected to the first motor; a second motor driver electrically connected to the second motor; and a processor electrically connected to the first motor driver and the second motor driver, wherein the processor may control the first motor driver to drive the first motor to close the first door at a time different than a time the second door that is connected to the second motor driven by the second motor driver closes.

An opening structure includes a lower door having an upper end configured to be rotated and opened with respect to a lower surface of a vehicle body, a garnish unit located on a surface of the lower door, at least a portion of a lower end of the garnish unit configured to be tilted from the lower door, a driving unit extending in a longitudinal direction and configured to apply driving force to the lower door and the garnish unit, a first driver configured to tilt the garnish unit, a second driver configured to integrally pop up the tilted garnish unit and the lower door and to apply opening force thereto, and a hinge arm connecting the first driver and the second driver to each other.

A gatebox system for delivering fire retardant fluid from a firefighting aircraft. A first and second gate opening are formed through a lower portion of a gatebox. The gates are hingedly connected along edges of the openings. One or two drive shafts in the gatebox are rotatable in gates-closing and gates-opening directions. Crank arms are fixed to the drive shafts and coupled to the gates by connecting links, which define an over-center geometry while the gates are at a closed position, such that weight of the fluid on the first gate induces torque on the drive shaft in the gates-closing direction. Rotation of the drive shafts in the gates-opening direction enables control of the fluid flow from the hopper according to an angular position of the drive shaft.
