Abstract: A carrier device includes a coupling mechanism for connecting an automatic controlled vehicle to a carriage. The coupling mechanism includes a first roller assembly and a second roller assembly. The first roller assembly includes a first roller and a third roller, provided on a first common shaft. The second roller assembly includes a second roller and a fourth roller, provided on a second common shaft. The first roller and the second roller can enter a gap of the guide rail section in the automatic controlled vehicle. When the lock member moves from the first position to the second position, the lock member is sandwiched between the third roller and the fourth roller.

Abstract: Actuator elements are accommodated in openings formed in a conductive plate. These actuator elements are secured to the conductive plate by a resin bonding material. An electrode of each actuator element and the conductive plate are electrically connected to each other by a bridge junction consisting of an conductive paste. A paste application device discharges the conductive paste toward the bridge junction by air. A control unit configured to control the discharge of the conductive paste sets the air pressure according to the elapsed time of use of the conductive paste so that the height of the paste above the resin bonding material is not less than a target height. The target height is maintained by increasing the air pressure with increase of the elapsed time of use of the conductive paste.
