摘要： A microceramic linear actuator includes a unitary ceramic body which has been formed with an internal cavity; a piston mounted for linear movement within the internal cavity and having a micromagnet with first and second poles of opposite polarity, and at least one shaft attached to the micromagnet; a conductive coil embedded in the unitary ceramic body and having a first portion wound in a clockwise direction and disposed in operative relationship to the first pole of the micromagnet, and a second portion wound in a counterclockwise direction and disposed in operative relationship to the second pole of the micromagnet. A power supply applies current in first and second directions to the coil such that when the current is applied in the first direction it flows through both coil portions, and the clockwise portion of the coil imparts a force to the first pole of the micromagnet, and the counterclockwise portion of the coil imparts a force to the second pole of the micromagnet thereby causing such micromagnet and its attached shaft to move in the first linear direction, and when it is applied in a second direction the clockwise portion of the coil imparts an opposite force to the first pole of the micromagnet, and the counterclockwise portion of the coil imparts an opposite force to the second pole of the micromagnet thereby causing such micromagnet and its attached shaft to move in a second linear direction.

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 for making 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.
