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 improve environmental resistance by enlarging the degree of freedom for material selection of a resin code disc of an optical encoder.
SOLUTION: A material having a spectral transmittance of 70% or higher to detection light and having a spectral transmittance of 50% or lower to part of light having a visible wavelength (for example, blue light) is adopted in a translucent part relative to at least a code pattern of the code disc in the optical encoder. When using infrared light having the wavelength of 800-1,000 nm as the detection light, polyether imido, polyether sulfone or polyphenyl sulfone is preferably adopted as a colored resin material. These materials are excellent in heat resistance, oil resistance or the like compared with conventional transparent and colorless materials (PMMA, PC, glass or the like), and hardly generate dissolution, deformation, clouding or the like even in a severe environment.
