摘要： An imaging processor for receiving a medium for processing, the processor comprises a print head for providing and for directing a writing laser beam. A laser source also disposed in the image processor for creating a focusing laser beam for ultimately permitting adjustment of the writing laser beam. An imaging receptacle receives the medium and is exposed to both the writing and focusing laser beams, and the writing laser beam is periodically directed from the medium, to the imaging receptacle and back to the medium. A laser-absorbent coating is coated onto the imaging drum for absorbing the focusing laser beam that is received by the imaging receptacle for substantially eliminating transient oscillations in the writing laser beam.

摘要： A dielectric member with an integral, electrically conductive surface is made by molding a substrate from a zirconia alloy powder using a tape casting process. The resulting green substrate is sintered and after sintering may be cut to the final desired size and shape. Once the insulating ceramic substrate has been formed, the surface of the substrate is modified using infrared laser energy. Through the impingement of infrared laser radiation upon the surface of the ceramic substrate, an electrically conductive region is produced on the surface of the substrate. In such manner, the entire surface can be made electrically conductive or a particular pattern can be traced. As an integral part of the substrate, the surface will not delaminate from the substrate. Further, because the modified surface region and the substrate are both a zirconia, the coefficients of thermal expansion of the substrate and the modified surface region will be closely matched.

摘要： A method for making electromechanical parts and tools having at least one micro-diameter electrically conductive thread incorporated therein is accomplished by molding the elements which form the base for the electromechanical part or tool from a ceramic material and, during the molding step, there are formed one or more bores through each of the base elements. The base elements may be formed individually or at a planar array for later separation into individual elements. The base elements are then supported on a micro-porous substrate within a vacuum chamber and one side of the base element is flooded with a molten electrically conductive material. By drawing a vacuum within the vacuum chamber beneath the micro-porous substrate, the molten electrically conductive material is caused to flow into and through at least one bore in each base element. The molten electrically conductive material is then cooled. In such manner, through the molding of the ceramic material into the desired shape with desired bores forming conduits for the molten electromechanical material, a variety of micro-electromechanical parts and tools can be fabricated.

摘要： Flexible and reusable lithographic printing tapes are prepared from a zirconia ceramic that is an alloy of ZrO.sub.2 and a second oxide chosen from MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, a rare earth oxide or a combination of any of these. These printing tapes have an average thickness of less than about 5 mm. In use, a surface of the zirconia alloy ceramic printing tape is imagewise exposed to electromagnetic radiation which transforms it from a lydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. Such inked areas can then be used to transfer an image to a suitable substrate in lithographic printing. These printing tapes are directly laser-imageable as well as image erasable.

摘要： A method for fabricating a multiwound microcoil embedded in a ceramic substrate including the steps of forming a sacrificial multiwound microcoil, having a melting temperature greater than the sintering temperature of the ceramic material to be used as the ceramic substrate by wrapping a first sacrificial coil winding in a helical fashion on the midsection of a sintered ceramic bar thereby forming a one winding sacrificial coil structure; wrapping a first layer of tape cast ceramic material around the midsection of said one winding sacrificial coil structure thereby forming a first coated one winding sacrificial coil structure; wrapping a second sacrificial coil winding in a helical fashion on the midsection of said first coated one winding sacrificial coil structure thereby forming a two winding sacrificial coil structure. The method further includes forming green ceramic material into the shape of the ceramic substrate incorporating said formed sacrificial multiwound microcoil; sintering the green ceramic material; removing the sacrificial multiwound microcoil from the sintered ceramic substrate; flowing molten electrically conductive material into the space relinquished by the removed sacrificial multiwound microcoil; and cooling the molten electrically conductive material to fabricate the multiwound microcoil embedded in a ceramic substrate.

A mold is provided for receiving and processing the ceramic powder thereby forming a ceramic billet. Shaping of the ceramic billet is undertaken to form a near net-shaped ceramic bearing. Thereafter, the near net-shaped ceramic bearing is sintered resulting in a sintered ceramic bearing. After sintering, the ceramic bearing is further shaped or machined. After forming the ceramic bearing, at least two air inlet ports are formed in the body portion of the bearing in fluid communication with air channels having preferably a spiral pattern formed in at least one flange portion of the bearing.
