摘要： An improved die retaining element has a highly efficient, durable and wear and abrasion resistant flange portion surrounding an opening for securing a die mold therein. The flange portion may have practically any geometric configuration, such as round, but is most effective when in a continuous plane with the powder feed box in sliding contact with a feed box. In particular, the flange portion may selectively have either a high precision tetragonal zirconia polycrystal (TZP) ceramic or zirconia-alumina ceramic composite, depending on the surface material of the feeder box in sliding contact therewith. In one embodiment, the flange portion has tetragonal zirconia polycrystal ceramic and the feeder box has zirconia-alumina ceramic composite sliding surface. In another embodiment, flange portion has a zirconium-alumina ceramic composite sliding portion and the feeder box has a tetragonal zirconia polycrystal ceramic sliding portion.

摘要： A ceramic conveyance roller having a tetragonal phase crystal grain structure includes zirconium oxide and yttria and the molar ratio of yttria to zirconium oxide of from about 3:97 to about 5:95. The outer surface of the ceramic roller has a dimensional tolerance of less than 0.003 inches and the inner surface has a dimensional tolerance of less than 0.0005 inches. The outer surface of the roller can be modified to the cubic phase crystal grain or the monoclinic phase crystal grain.

摘要： A dual speed film drive apparatus to achieve high speed and low speed film drive employs a limited speed range stepper motor with pinion input drive gear, and an output driven gear connected to a film advance mechanism. High and low speed drive is achieved by use of a pivoted intermediate gear drive module having high speed and low speed gear set positions to interconnect the stepper motor input drive gear to the output driven gear. Shifting of the gear module between gear set positions is accomplished by a DC motor operated cam drive mechanism which pivots the gear module selectively between the high speed and low speed gear set positions. An open loop control gear mesh procedure is also described for meshing the high speed and low speed intermediate gear drives with the input drive gear and output driven gear.
