20120279342 | MOTOR, ROBOT HAND, AND ROBOT - A motor including a driven unit; an actuator including a vibrating plate having, at an end thereof, a protrusion which is biased toward the driven unit and a piezoelectric body stacked on the vibrating plate; and a biasing unit biasing the actuator toward the driven unit, wherein an axis in a direction in which the biasing unit biases the actuator toward the driven unit intersects with a plane containing a vibrating surface of the vibrating plate. | 11-08-2012 |
20120308355 | MOTOR, ROBOT HAND, AND ROBOT - A motor includes: a driven unit having a cylindrical shape; an actuator having a protrusion abutting on the driven unit; and an impelling unit impelling the actuator against the driven unit, wherein, assuming that the trajectory of the protrusion is disposed to abut on a side surface of the cylindrical shape at a contact point P and a point of action where an impelling force is exerted on the actuator is a point of action Q, the relation between an angle θ1 between the impelling direction of the impelling unit and a direction connecting a rotational center R of the driven unit and the contact point P and an angle θ2 between the impelling direction of the impelling unit and a direction connecting the contact point P and the point of action Q satisfy a relationship of θ1<θ2. | 12-06-2012 |
20130140951 | PIEZOELECTRIC MOTOR, DRIVE UNIT, ROBOT HAND, ROBOT, ELECTRONIC COMPONENT TRANSPORTING APPARATUS, ELECTRONIC COMPONENT INSPECTING APPARATUS, AND PRINTER - A piezoelectric motor includes a piezoelectric element, a first support member, a second support member, a third support member, and a fourth support member that support the piezoelectric element, a elastic portion that presses the first support member and the second support member, a case that comes in contact with the third support member and the fourth support member, and a pressing plate that presses the elastic portion. | 06-06-2013 |
20130140953 | ACTUATOR, ROBOT HAND, ROBOT, ELECTRIC COMPONENT CONVEYING APPARATUS, ELECTRONIC COMPONENT TESTING APPARATUS, AND PRINTER - An actuator includes a vibrating piezoelectric element and a holding section configured to hold the piezoelectric element. The holding section includes a first supporting section arranged on a vibrating surface of the piezoelectric element and arranged on one side of the piezoelectric element and a second supporting section arranged on the other side of the piezoelectric element. | 06-06-2013 |
20130140954 | ACTUATOR, ROBOT HAND, ROBOT, ELECTRONIC COMPONENT CARRYING DEVICE, ELECTRONIC COMPONENT INSPECTION DEVICE, AND PRINTER - An actuator includes a vibrating piezoelectric element, and a holding unit that holds the piezoelectric element, in which the holding unit is disposed on a vibrating surface of the piezoelectric element, and includes a first support unit and a second support unit that are disposed on one side of the piezoelectric element, and a third support unit and a fourth support unit that are disposed on the other side of the piezoelectric element. | 06-06-2013 |
20130141564 | PIEZOELECTRIC MOTOR, DRIVING DEVICE, ELECTRONIC COMPONENT INSPECTION DEVICE, ELECTRONIC COMPONENT CONVEYING DEVICE, PRINTING DEVICE, ROBOT HAND, AND ROBOT - A vibrating body which is formed of a piezoelectric material and has a convex portion in an end surface is accommodated in a vibrating body case, the convex portion of the vibrating body is pressed against an object along with the vibrating body case, and the vibrating body vibrates to drive the object. An end surface of a front-side pressure spring which presses the vibrating body case against a slide portion of a base is fitted into the vibrating body case such that the vibrating body case does not escape due to a reaction force during driving. | 06-06-2013 |
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 |
20150094636 | FINGER ASSISTIVE DEVICE - A finger assistive device is formed by connecting a second member to a first member so as to be rotatable in a bending direction of a finger. Further, either one of the first member and the second member is provided with a relative position changing section adapted to change a relative position of the second member to the first member in a direction different from the rotatable direction. According to this configuration, by changing the relative position of the second member to the first member in accordance with a length and a shape of the finger of the wearer, the finger assistive device can be customized (adjusted) so that the first member and the second member fit the mounting positions of the finger. As a result, it becomes possible to appropriately mount the finger assistive device to the finger and appropriately assist in bending the finger. | 04-02-2015 |
