| 20080272673 | COMPACT SIZE ELECTROMECHANICAL TRANSLATION APPARATUS - A linear electromechanical translation apparatus is provided of the type comprising first and second clamps fixed to a support, first and second elongate movable members each extending through one of the clamps, and an extension actuator connected between the movable members and adapted to move each one of the elongate movable members longitudinally relative to the other member as the extension actuator is extended or retracted. The apparatus is characterized in that the first elongate movable member has a rear end connected to a front end of the extension actuator, and the second movable member has a rear end connected to a rear end of the actuator and has a forwardly extending elongate portion which lies beside and parallel to the first elongate movable member. Both the clamp assemblies may be located forwardly of the front end of the actuator. | 11-06-2008 |
| 20090021115 | DRIVING APPARATUS, AND MANUFACTURING METHOD OF THE SAME - A driving apparatus comprises: an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line; a driving shaft mounted on one end of the electromechanical conversion element in the extending direction; a driven member frictionally engaged with the driving shaft; a holder that supports the electromechanical conversion element and comprises a bearing portion for the driving shaft; and an inclination adjusting mechanism, disposed in the bearing portion, that adjusts inclination of the driving shaft with respect to the fiducial line. | 01-22-2009 |
| 20090021116 | DRIVING APPARATUS - A driving apparatus comprises: an electromechanical conversion element that expands and contracts in an extending direction of a given fiducial line; a driving shaft that is fixed to one end of the electromechanical conversion element in the extending direction; a driven body that is frictionally engaged with the driving shaft; a holder that holds, through an adhesive, the electromechanical conversion element from lateral sides with respect to the extending direction; and a flange member that is provided on the driving shaft between (i) a moving region of the driven body on the driving shaft and (ii) the electromechanical conversion element. | 01-22-2009 |

| 20120306317 | MULTI-AXIS ACTUATING APPARATUS - A multi-axis actuating apparatus for a nano-positioning apparatus includes a movable element attached to a sample platform, a plurality of driving elements, and a plurality of actuators. The driving elements frictionally engage the movable element and are configured to selectively move the movable element along a first direction. The plurality of actuators move the plurality of driving elements when driving signals are applied to the plurality of actuators. Different driving signals may be applied to the plurality of actuators to cause different movement of the driving elements such that the movable element has different displacements in different directions along the plurality of driving elements. The movable element is titled due to the different displacements. | 12-06-2012 |
| 20130181576 | HANDLER AND TEST APPARATUS - A handler includes a supporting section, a holding section configured to hold an IC chip, and a position changing section between the supporting section and the holding section and configured to change the position of the IC chip held by the holding section. The position changing section includes a two-dimensional moving section that is movable in a predetermined direction, a pivoting section that is pivotable with respect to the two-dimensional moving section, and a piezoelectric actuator configured to move the two-dimensional moving section with respect to the supporting section. | 07-18-2013 |
