摘要： PROBLEM TO BE SOLVED: To improve the coaxial degree of rotation shafts in a coupling of a motor and an encoder regardless of the process accuracy of an inlay, and also to improve the rotation accuracy of the motor by improving the coaxial degree of the rotational shafts. SOLUTION: The motor is provided with the encoder 2 for detecting a rotation angle and the coupling 3 for coupling the rotation shafts of the encoder and the motor body 1. The encoder attachment of the motor body and the motor attachment of the encoder are provided with one or more positioning holes 4a, 4b, 5a, 5b for coaxially positioning the rotation shafts. Since a positioning pin 6 penetrates into both positioning holes, the motor for positioning the encoder to the motor body is provided with positioning openings in a flange through which the motor and the encoder face each other, and both openings are coupled by the positioning pin.

摘要： PURPOSE: To provide a driving device for a linear actuator by which the position, velocity and the direction of movement of a traveling object are controlled. CONSTITUTION: A triangular wave signal of a frequency corresponding to a velocity command is outputted from a triangular wave signal generation means 30. The piezoelectric elements B, B' for movement of a first and second grip type linear actuators are driven through amplifiers 42, 42'. When the triangular wave signal is increased and decreased, the synchronizing signal of a reversing rectangular wave is formed. Grip signals GS1, GS2 of both the same signal as the synchronizing signal and a signal of the reversed synchronizing signal are changed over and outputted in accordance with the direction of a movement command. Piezoelectric elements A, A' for grip are driven through the amplifiers 41, 41' and a traveling object 20 is alternately gripped by grip parts 2, 2'. Since the traveling object 20 is gripped while synchronizing with extension and contraction of the piezoelectric elements B, B' for movement, the traveling object 20 is moved in the direction of the movement command. The traveling object 20 is moved continuously and smoothly at the command velocity because it is driven by the triangular wave signal. High-speed movement is enabled and reciprocating movement of a long stroke is enabled.

摘要： PURPOSE: To provide a grip type linear actuator in which strong grip force is generated uniformly by a grip part. CONSTITUTION: Arms 11 which magnify displacement and transmit to a grip parts 12 are connected with both ends of a piezoelectric element A through elastic hinges h12. The grip parts are equipped with an elastic direction adjustment part 12b for adjusting the direction of a grip face 12a. The piezoelectric element A is connected with the installation part 16 of a piezoelectric element B through an elastic connection part 13. In automatic adjustment, the grip parts are moved by switching on the piezoelectric element A so that the elastic direction adjustment parts 12b is brought into contact with the surface of a moving body. When there is a difference in the grip force between the two grip parts, the elastic connection part 13 is deflected so that the arms 11 and the piezoelectric element A are moved horizontally to make the grip force of the two grip parts equal. In this grip condition, when the piezoelectric element B is switched on or off, the moving body is moved vertically with the grip parts by the force generated from the piezoelectric element B or the shrinking force of a flat spring 17.

摘要： PROBLEM TO BE SOLVED: To relieve the processing precision, to produce a gripping force efficiently and to suppress the decline of the gripping force even if the gripping part is worn out. SOLUTION: An actuator 1 is composed of two structures A and B having identical shapes and dimensions. A gripping part 10 is horizontally moved by a moving piezoelectric device 3. The gripping parts 10 and 10 are vertically opened and closed by gripping piezoelectric devices 4. The gripping parts 10 and 10 are held between the elastic gripping plates of a gate-shaped slider. The gripping parts 10 and 10 of the two structures A and B are alternately opened to push the gripping plates of the slider to open and an object is gripped. The slider is moved in a moving direction (left/right direction in the Fig.) by a displacement caused by the operation of the moving piezoelectric device 3 while the object is gripped. As the gripping parts 10 and 10 are pressed by the gripping plates of the slider, the displacements of the gripping parts 10 and 10 are converted into a gripping force which is increased and the propelling force of the slider is increased. As it is so constructed as to press the gripping parts 10 and 10 by the gripping plates of the slider, it is not necessary to process the gripping surfaces of the slider with the especially high precision.

摘要： PROBLEM TO BE SOLVED: To provide a grip type linear actuator in which dimensional control is simplified while producing a high thrust and stabilized movement of a mover is realized. SOLUTION: When a piezoelectric element C for grip is turned off, a mover is gripped by the grip parts Gb, Gb at a grip switching mechanism section 4 and the grip parts Gb, Gb are separated from the grip surface of mover. When the piezoelectric element C is turned on, the Ga, Ga grip the mover and the Gb, Gb are separated from the grip surface of mover. When piezoelectric elements A, B for motion are turned on with the piezoelectric element C being turned off, the mover gripped by Gb, Gb is moved upward. Displacement of the piezoelectric element A is absorbed at a motion displacement absorbing part 5 and not transmitted to the Gb, Gb. When the piezoelectric element C is turned on and the piezoelectric elements A, B are turned off, the mover gripped by Ga, Ga is moved upward. The operation is repeated to move the mover over a long distance. When the operation of the piezoelectric elements A, B, C is reversed, the mover is moved reversely.

摘要： PURPOSE:To set a thrust large, and a stroke large by pushing and holding a movable body by controlling application of a voltage to a piezoelectric element for gripping, applying the voltage to a piezoelectric element for moving for moving a grip part holding the movable body, and returning the grip part when holding of the movable body by the grip part is released. CONSTITUTION:At an off time when a voltage is not applied to a piezoelectric element A for gripping, a grip part 2 is moved to a position for pushing and holding a movable body to hold it. In this condition, oscillation parts 1a, 1a oscillate about support points of resilient hinges h1, h2, and the grip part 2 pushes and holds the movable body. Application of a voltage to a piezoelectric element B for moving gets on, next, to move the grip part 2. The movable body is thus moved. The voltage is then applied to the piezoelectric element A for gripping, and holding of the movable body is released, when application of the voltage to the piezoelectric element B for moving gets off. The reilient hinges h1, h2 act inversely by this, so holding of the movable body by the grip part 2 is released, and it returns to an initial position.
