    Abstract: A conveyer equipped with rotating discs rotatable around axes thereof relative to a mounting base. Each of the rotating discs has grooves in which rectangular wires are receivable. When an upstream and a downstream one of the rotating disc are arranged in a given angular relation to each other, one of the grooves of the upstream rotating disc is aligned with that of the downstream rotating disc to pass the rectangular wire from the upstream rotating disc to the downstream rotating disc. Upon such passing of the rectangular wire, the grooves of the upstream and downstream rotating discs hold or clamp all side surfaces of the rectangular wire, thereby ensuring the stability in retaining the rectangular wire when passed from one to another of the rotating discs, which enables the conveyer to carry the rectangular wires at high speeds.

    Abstract: A dielectric elastomer transducer includes a dielectric elastomer function element having a dielectric elastomer layer and a pair of electrode layers between which the dielectric elastomer function element is interposed, and further includes a supporting body that supports the dielectric elastomer function element. Each of the electrode layers has one or more application regions. The dielectric elastomer function element has one or more function portions on which the application regions of the electrode layers are overlapped. The function portion is spaced away from the supporting body. With such a configuration, it is possible to avoid damaging the electrode layer and acquire a sufficient amount of expansion.
