摘要： A microceramic electromagnetic light shutter is disclosed including a unitary ceramic body having an internal cavity. A conductive coil is formed in the internal cavity. The unitary ceramic body defines a first and second bearing structure on it's surface. The unitary ceramic body has a light aperture and first and second recesses. The microceramic electromagnetic light shutter further includes a shutter drive mechanism including a shutter blade and a ferromagnetic element inserted into the first recess and operative to the shutter drive mechanism for applying a torque to the shutter drive mechanism which causes the shutter drive mechanism to move so that the shutter blade is in it's light blocking position. The shutter drive mechanism is mounted in the second recess an in an operative relationship to the coil and ferromagnetic element. The shutter blade is movable between a light blocking and light passing positions relative to the light aperture so that when a drive voltage is applied to the coil a field is created by the coil which provides a torque to the shutter drive mechanism to overcome the torque applied by the ferromagnetic element thereby causing the shutter blade to move to the light passing position. When the drive voltage is discontinued the ferromagnetic element provides a torque on the shutter mechanism causing the shutter blade to return to the light blocking position.

摘要： A method of making a print head (100) includes forming a body (110) having a closed base (120) and independent fluid containment compartments (220) formed about the closed base (120). 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 electrodes (20) arranged on a first surface (62) of the slab (60) of piezoelectric material and a portion of a second 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).
