An electrode array for an electrooptical facsimile recorder and a method of controlling this electrode array are disclosed. A plurality of spot electrodes are inserted between two main electrodes deposited on a lead lanthanum zirconate titanate (PLZT) substrate. In this manner, three partial lines of electrically controllable light gates are formed which provide a line-at-a-time output of the information to be reproduced. The individual light gates are controlled by driver ICs with push-pull output stages. To control the individual partial lines, different voltages must be applied to the main and spot electrodes.

Electrode array for an electrooptical facsimile recorder and method of

A high-resolution position sensor utilizes a detector having at least one flat magnetic-field-dependent resistor, in stripe form, whose ends are connectable to an output voltage, and a magnetizable device which is moveable relative to the magnetic-field-dependent resistor and has portions transverse to the direction of movement which exhibit alternately different space permeabilities, with the magnetic-field-dependent resistor extending parallel to and at a distance from said portions by the magnetic-field-dependent resistor. The magnetic field dependent resistor displays anisotropy in the longitudinal direction of the stripes. At least in the area of the magnetic-field-dependent resistor the device is magnetized in or opposite the direction of movement.
