Abstract: A scanning device having: (i) an electrooptic planar waveguide or bulk material capable of propagating light beams with minimum beam distortion, (ii) an electrooptic prism array defined on said electrooptic planar waveguide or bulk material, comprised of at least one pair of antiparallel-poled ferroelectric domain regions and, (iii) control means to apply a spatially uniform electric field throughout said electrooptic prism array using a pair of electrically-addressable continuous electrodes, so as to induce an electrically-controlled deflection to a light beam propagating through the device.

Abstract: The actuating device for a master cylinder is constituted by an actating rod (10) acting on a piston (12) of the master cylinder. Elastic centering mechanism (26) are arranged between the actuating rod (10) of the master cylinder and the piston (12) of the master cylinder, and are compressed therebetween.
