摘要： An ink jet printing element (200) includes a body (110) comprising a ceramic composite material that has a closed base (120) and independent fluid containment compartments (220) formed about the closed base (120). Preferred ceramic composite materials include tetragonal zirconia alloy, zirconia-alumina composites and a mixture thereof. A substantially planar piezoelectric transducer (80) comprising a slab (60) of piezoelectric material provides a means of enclosing each of the independent fluid containment compartments (220). Each of the independent compartments has operably associated therewith one of a plurality of first surface electrodes (20) arranged on a first surface (62) of the slab (60) of piezoelectric material and a portion of a second surface electrode (22) arranged on an opposite second surface (64). By applying a voltage to the first and second surface electrodes (20, 22) in a predetermined manner induces an electric field in a portion of the slab (60) of piezoelectric material and thereby forces fluid composition through the independent fluid containment compartment (220).

The image receiving surface is illuminated with light in the pattern corresponding to an image so that the image receiving surface has electrically conductive and nonconductive portions which taken together represent the image. The image receiving surface is charged such that charge remains on the nonconductive portions of the image receiving surface. Toner particles are provided which adhere to the image receiving surface in the electrically conductive portions defining a developed image. Charged toner particles defining the developed image are transferred to the receiver and then the charged toner particles are fixed to the receiver.

摘要： A modulator for modulating an incident beam of light includes a substrate having a cavity formed therein and a plurality of spaced-apart deformable elements formed in the cavity. The deformable elements each has a base layer, a poled magnetic layer formed in the base layer and a first light reflection layer deposited on the magnetic layer for reflecting an incident beam of light. Between adjacent deformable elements on the base of the cavity is arranged a second light reflection layer. A conductive element formed in the substrate electro-magnetically energizes the deformable elements to deflect in the cavity. Incident light passing through each one of the first light reflection layers is caused to destructively interfere with light reflected from the second light reflection layers thereby causing modulation of the incident light.
