摘要： A suction pad comprises a workpiece attracting section made of a metallic material and brought to contact with a surface of a workpiece; a main body made of a flexible material and integrally coupled to the workpiece attracting section; an adapter made of a metallic material and attached to the main body; and a spring member made of a metallic material with one end thereof connected to the workpiece attracting section and the other end thereof connected to the adapter. A rotation-stop and guide mechanism for a suction pad comprises a spline shaft having splines and coupled to the suction pad, a cylindrical member externally fitted to the spline shaft and displaceable along the spline shaft, and a plurality of balls arranged between the cylindrical member and the spline shaft, the balls forming a rotation-stop in cooperation with the splines that stops the rotation of the cylindrical member against the spline shaft, rolling upon displacement of the cylindrical member along the spline shaft.

摘要： To attract a workpiece with a limited contact region, e.g., a doughnut-shaped compact disc having a central circular hole, a skirt of a substantially arcuate attractor is held against an annular land extending around the central circular hole. Suction forces are applied through a plurality of suction holes surrounded by the skirt to attract the annular land for attracting and carrying the compact disc. A mini disc having an annular step along a peripheral region around a central hole thereof may stably be attracted and carried by an attractor having inner and outer annular contact members which axially project different distances to contact the peripheral region and an area, respectively, that is radially spaced from the peripheral region by the annular step.

摘要： A driving force is transmitted from a driving section to a cylinder mechanism having a piston while subjected to speed reduction. Further, an operation oil is charged into a rotary housing of a power transmission switching mechanism that is arranged between the driving section and the cylinder mechanism. First plates and second plates are alternately arranged along an inner shaft, the first plates being connected on a side of the driving section, and the second plates being connected on a side of the cylinder mechanism.

摘要： A skirt section has a plurality of substantially elliptic projections and a recessed portion formed on an attracting surface thereof. The skirt section is separated from each other by predetermined spacing distances along a circumferential direction of the skirt section on concentric circles. The recessed portion enables a fluid under the negative pressure to be supplied to the entire attracting surface except for the projections. Even if oil film or water droplet adheres to an attracted surface of a workpiece, the workpiece can reliably be attracted without causing a slip.

摘要： An actuator has a linearly elongate frame, side, end, and top covers detachably and selectively mounted on side surfaces of the frame, a table mechanism displaceable in the axial direction of the frame in response to energization of an electric motor, and a ball screw for transmitting drive forces from the electric motor to the table mechanism. The operator can select various actuator configurations depending on the environment in which the actuator is to be installed and the application in which the actuator is to be used. In the preferred embodiment, the ball screw is used in combination with a piston/cylinder arrangement for moving the table mechanism in a linear direction. The piston/cylinder having a magnetic coupling for coupling the piston to the table mechanism.
