    摘要： An actuator includes an inverter, a stator, a movable part, a controller, an injector, a current detector, and an estimator. The inverter is driven by a power generated by the axial force of an engine, etc. The stator includes an armature coil driven by the inverter. The movable part applies a driving force to at least one of a rudder surface of a tailplane of the airplane, etc. The controller controls the inverter in accordance with a signal from a maneuvering system. The injector injects a high-frequency signal into the coil. The current detector detects a coil current. The estimator estimates a position of the movable part.

    摘要： To provide a liquid cooling system for an electric component mounted in an aircraft, in which a flow rate of a coolant fed to the electric component mounted in the aircraft is optimized by a simple method, a liquid cooling system 1 for an electric component mounted in an aircraft adopts a flow rate adjusting valve which is a thermostat valve 5 such that the opening degree of the valve increases with an increase in the temperature of the coolant flowing into the flow rate adjusting valve so as to raise the flow rate of the coolant fed to the electric component 50, and the opening degree of the valve decreases with a decrease in the temperature of the coolant flowing into the flow rate adjusting valve so as to reduce the flow rate of the coolant fed to the electric component 50.

    摘要： A linear drive portion is fixed to a piston. A nut portion and a screw portion relatively rotate, and a direction of action of driving force is converted between a rotational direction and a linear direction. The piston is installed within a case. The inner circumference of a piston sliding portion fixed within the case slidably supports the outer circumference of the piston. The nut portion is displaced with the piston, and the screw portion rotates in conjunction with a rotational drive portion. The piston is installed so as to be able to slide in the axial direction of the case with respect to the piston sliding portion. The axis of the piston and the central position of the inner circumference of the piston sliding portion are set to be eccentric with respect to the axis of the screw portion and the nut portion.

    摘要： A switching device includes: a lower switching element, an upper switching element having a source connected to a drain of the lower switching element; a control circuit including a first output part that supplies a driving signal to the lower switching element; a Zener diode having a cathode connected to the first output part; a parallel capacitor connected to the Zener diode in parallel; a resistor connected between an anode of the Zener diode and a gate of the lower switching element; and a gate-side capacitor provided separate from a parasitic capacitance of the lower switching element, having a larger capacitance than the parasitic capacitance of the lower switching element, and connected, outside the lower switching element, between the gate and a source of the lower switching element. The capacitance of the gate-side capacitor is smaller than a capacitance of the parallel capacitor.
