    摘要： To provide an actuator which is easily made a small size and flexible, and has a large displacement. The actuator comprises a rod-shaped actuator element, having one axial end thereof fixed, including a dielectric film made of a dielectric elastomer and a plurality of electrodes arranged via the dielectric film, in the actuator element, the dielectric film extends as a voltage applied across the electrodes becomes large, and a load member connected to the other axial end of the actuator element and fixed in a state in which the actuator element is permitted to be extended axially, characterized in that making large the voltage applied across the electrodes causes the dielectric film to be extended, whereby the actuator element is extended axially according to the tension of the load member .

    摘要： A conductive roll available at low cost and superior both in moldability and compression set and having small disperation or fluctuation in electrical resistance includes a shaft and a base rubber layer formed on a peripheral surface of the shaft, the base rubber layer formed of a composition containing the following components (A) to (C) :

    (A) a liquid polymer having a structural unit ( α ) derived from at least one of butadiene and isoprene and having an alkenyl group in a side chain thereof;
    (B) a hydrosilylation crosslinking agent; and
    (C) a hydrosilylation catalyst.
    In the conductive roll the alkenyl group of the structural unit ( α ) in the liquid rubber (component A) becomes a crosslinking site and is present in a molecule thereof as a so-called pendant form so that the base rubber layer as a crosslinked mold comes to have a dense net structure due to the effects by the hydrosilylation crosslinking agent (component B) and the hydrosilylation catalyst (component C), thereby to obtain good copied images.

    摘要： A roller for office automation equipment which does not suffer from impairment of a cross-linking reaction or occurrence of a delay therein, is excellent in permanent set resistance and low-temperature bleedability, and permits achievement of a low hardness. The roller for office automation equipment comprises a base rubber layer (2), an intermediate layer (3) and a surface layer formed (4) in this sequence on an outer peripheral surface of a shaft (1), wherein the base rubber layer is formed of a liquid rubber composition containing the following constituents (A-D):

    (A) a liquid rubber, derived from at least one of butadiene and isoprene, and having a structural unit (α) having an alkenyl group on the side chain thereof;
    (B) a hydrosilyl cross-linking agent;
    (C) a hydrosilylation catalyst; and
    (D) a mineral oil containing not more than 0.31wt.% sulfur.
