Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.

Abstract: A vibration damping device including a vibration-damping device main unit inserted into a mounting space of a bracket from a lateral side and securely supported by the bracket. The bracket includes engaging pieces on respective opposed inside faces of the mounting space, and engaging action of the engaging pieces with respect to respective detent engaging faces formed on a fixture member of the vibration-damping device main unit prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket. Opposed walls of the mounting space are each penetrated by an aperture window, and inspection flat surfaces are separately provided to an outside surface of each engaging piece visible from an outside through the aperture window and a corresponding external side surface of the bracket that is off the aperture window. The inspection flat surfaces are parallel to each other.

Abstract: [Object] There has been a need for a composite piezoelectric body and a composite piezoelectric element using the composite piezoelectric body which does not cause electrode defects, disconnection, and peeling even if the piezoelectric body is subjected to fine-pitch processing. [Solution] A composite piezoelectric body of the present invention includes a piezoelectric ceramic and an organic polymer material containing air bubbles mixed therein, wherein among surfaces of the piezoelectric ceramic and the organic polymer material on which an electrode is to be formed, an insulating layer is formed on the entire or a portion of the surface of the organic polymer material on which the electrode is to be formed.
