  • Patent number: 9630705
    Abstract: The present invention provides a drive system which can automatically deploy a ground spoiler even when a wheel is locked.

  • Patent number: 9553614
    Abstract: Provided is a technique capable of improving isolation characteristics between a plurality of signal paths through which RF signals pass, without using ground electrodes or the like. Wiring electrodes 10a and 20a through which RF signals do not pass simultaneously are formed so as to be adjacent to each other in a central region of a component mounting surface 2a of a circuit board 2, and wiring electrodes 11a and 21a through which RF signals pass simultaneously are formed so as to be distanced from transmission paths 10 and 20. Accordingly, the RF signals do not simultaneously pass through the transmission paths 10 and 20, which are disposed near each other, and thus there is no risk that the RF signal passing through one of the signal paths will interfere with the RF signal passing through the other signal path.

  • Publication number: 20140312170
    Abstract: The present invention provides an actuator device which can prevent a rapid change in deflection angle when an active actuator and a standby actuator are switched. A first actuator 21A drives an aileron upon supply of hydraulic oil through a hydraulic system 31L from a hydraulic power source 35L. A second actuator 21B drives the aileron upon supply of hydraulic oil through a hydraulic system 31C from a hydraulic power source 35C. In normal cruising, the actuator 21A functions in an active state, and the actuator 21B functions in a standby state. When a hydraulic pressure PA of the hydraulic oil in the system 31L is equal to or less than a predetermined first threshold value PL in the above states, the actuator 21A is switched from the active state to a standby state, and the actuator 21B is switched from the standby state to an active state.
