20090091829OPTICAL ELEMENT MODULE AND IMAGE PICKUP DEVICE - An optical element module includes an optical element, and a plurality of actuator elements. In the module, the plurality of actuator elements are arranged such that a direction of width of the oblong strip shape of the plurality of actuator elements is a direction of the optical axis and such that a direction of thickness of the plurality of actuator elements is perpendicular to the optical axis, another end part in a direction of length of the plurality of actuator elements is fixed such that one end part in the direction of length of the plurality of actuator elements is displaced by the bending to move the optical element, and at least one actuator element A of the plurality of actuator elements is disposed such that a direction in which the one end part of the actuator element A is displaced by the bending (X-direction) is orthogonal to a direction in which the one end part of another actuator element B is displaced by the bending (Y-direction).04-09-2009
20090091832OPTICAL ELEMENT MODULE AND IMAGE PICKUP DEVICE - An optical element module includes an optical element, and a plurality of actuator elements. In the module, each actuator element has an ion conductive polymer film and electrodes arranged on both sides of the film, and a whole of the actuator element is bent in a direction of thickness by applying a voltage between the electrodes, and the direction of the thickness of the actuator elements is a direction of an optical axis of the optical element, the actuator elements are arranged at equal intervals around the optical axis on a plane perpendicular to the optical axis, and a displacement due to the bend of one end part of at least one actuator element acts on one of a side surface and a bottom surface of the optical element to effect one of tilting and movement in the direction of the optical axis of the optical element.04-09-2009
20100244633ACTUATOR - An actuator includes: an ion conductive polymer layer including an ion conductive polymer; a pair of electrode layers disposed on both surfaces of the ion conductive polymer layer; and an ionic liquid contained in the ion conductive polymer layer and the electrode layers; wherein the electrode layers contain at least an ion conductive polymer and carbon powder, and kinds of carbon powders included on an inside and an outside of the electrode layers are different from each other.09-30-2010
20100244634ACTUATOR - An actuator includes an ion-conductive polymer layer made of a first ion-conductive polymer, a pair of electrode layers provided one on each side of the ion-conductive polymer layer and made of a second ion-conductive polymer and conductive powder, and ions contained in the ion-conductive polymer layer and electrode layers. The first and second ion-conductive polymers differ in functional group type from each other.09-30-2010
20100296175LENS MECHANISM AND IMAGING DEVICE - Disclosed herein is a lens mechanism including: a base; a guide member fixed to the base; a lens holding member adapted to hold the lens and which is held by the guide member in such a manner as to move straight along the optical axis; a rotary member adapted to rotate while at the same time engaging with part of the lens holding member so as to cause the lens holding member to move straight along the optical axis; and polymer actuator elements each of which has one end fixed to the base or guide member and the other end engaging with part of the rotary member so as to rotate the rotary member in a plane orthogonal to the optical axis.11-25-2010
20110012828PROTRUSION PATTERN FORMING DEVICE WITH DISPLAY FUNCTION - A protrusion pattern forming device with a display function includes a transparent elastic sheet having an internal layer including colored liquid, and an actuator including a plurality of actuator elements disposed along one surface of the elastic sheet, each of the actuator elements changing its own shape in response to an application of a voltage, thereby allowing the surface of the elastic sheet to protrude. A protrusion pattern is formed on the elastic sheet, and a dot pattern corresponding to the protrusion pattern is displayed on the elastic sheet by selectively driving the plurality of actuator elements.01-20-2011
