摘要： A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition caused exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation. A migration imaging method, which does not employ the bleachable composition of the present invention, wherein marking particles are magnetically attracted to the imaging element, is also provided.

摘要： A method and apparatus are presented for electrostatic deposition of dry powder to a tablet, capsule, or a specific area of any of a wide range of pharmaceutical substrates. The apparatus includes: a magnetic brush having a rotatable multi-pole magnetic core and a stationary outer shell; a developer supply for supplying a magnetic developer powder, consisting of a magnetic carrier particles and pharmaceutical dry powder particles, to the magnetic brush; a print head on the outer shell; a tablet or other pharmaceutical substrate arranged in spaced relation to the print head to define a pharmaceutical powder transfer region through which the substrate can be moved. The print head includes an array of microchannels for forming a plurality of parallel lines of developer in the channels, a corresponding plurality of transfer electrodes located in the microchannels for selectively transferring pharmaceutical powder from the lines to a substrate, driver circuitry for generating and applying transfer signals to the transfer electrodes, a power supply connection for applying power to the drive circuitry, a print signal input connection for applying print signals to the print head, and a logic and control circuit for applying the print signals to the drive circuitry.In one embodiment the width of an individual microchannel print head and the rotating multipole magnetic core is approximately the same dimension as the tablet or substrate to which pharmaceutical powder is to be deposited. In a further embodiment individual microchannel print heads can be arranged along the length of the shell to simultaneously deposit pharmaceutical powder to an array of tablets. In still a further embodiment the microchannel print head is shaped to conform to the tablet or capsule geometry to enhance deposition in three dimensions.In another embodiment the microchannel print head is formed on a silicon substrate onto which are also formed a multiplicity of individual drive circuits connected through separate conductive paths to individual transfer electrodes. In a further embodiment all the microelectronic circuitry necessary for the operation of the integrated microchannel print head is formed on the silicon substrate.

摘要： An AC corona charging arrangement includes a corona generating device connected through a capacitive connection to an AC voltage source and partially surrounded by a conductive shield connected to DC voltage source. In one embodiment the corona generating device is a wire having a diameter of about 50 microns and in another embodiment the corona generating device is a row of pins connected through corresponding capacitance to the AC voltage source. The presence of a capacitance between the AC voltage source and the corona generating device provides a curve representing the relationship between the current between the charging device and an adjacent conductive plate and the shield voltage which is concave downwardly, resulting in a high charging rate and greater uniformity of charging of a photoreceptor surface.

摘要： A magnetic brush development roller assembly for an electrographic printer, includes a cylindrical multipole magnet mounted for rotation about a cylindrical axis within a cylindrical shell. The stationary shell surrounding the multipole magnet defines an axial slot for receiving an imaging head, and has an increased thickness in the neighborhood of the slot and a reduced thickness in a neighborhood diametrically opposite the slot, whereby eddy currents generated by rotation of the magnet within the shell and hence drag on the magnet are reduced.
