    摘要: The object is to provide a polymer actuator capable of being utilized for any of various drive sources, wherein the amount of deformation of the polymer actuator can particularly be used also for a valve or shaft-sealing device. The polymer actuator comprises a power driver deformed upon receiving electro stimuli and electrodes disposed on the upper and lower surface sides of the power driver in an opposite manner for applying positive and negative electro stimuli to the power driver in a planar fashion. The electrodes have different stimuli application regions to have different electrical field distributions for causing distribution of stress generated in the power driver to be eccentrically located on one of positive and negative sides, thereby bending and deforming the power driver onto a side on which the opposite stimuli application regions do not exist.

    摘要: A shaft sealing device with a simple internal structure switches a sealing state and an unsealing state of a fluid, with high sealing performance maintained, because of no abrasion accompanying the movement of a sealing material or a sealing member, thereby enabling feeding a fluid at a predetermined flow rate, and adjusts the expanding rate of the sealing material with the quantity of an external electric signal and accordingly adjusts the contact face pressure to enable controlling the amount of leakage of the fluid highly precisely, so that it can be used for all applications. The shaft sealing device includes a shaft sealing body (20) formed of a macromolecular material and made expansible or contractible, or deformable, through external electrostimuli applied to a shaft sealing portion (15) disposed in a device body (10), and flow passages (13 and 14) disposed in the shaft sealing portion (15) for feeding the fluid leaked due to the expansion or contraction, or the deformation, of the shaft sealing body (20).
