    Abstract: A thin film electroluminescent display panel is driven with either a symmetric or asymmetric drive scheme which includes at least one equalizing voltage pulse per write cycle to remove carriers trapped at the interfaces of dielectric layers and phosphor layer in order to stabilize the charge of each display panel pixel. The present invention reduces the smearing, latent image and pseudo persistence problems caused by carriers being retained and accumulated at the dielectric and phosphor layer interfaces.

    Abstract: A process for producing a fine grain forged superalloy article having a high yield strength at intermediate temperatures. A preferred starting composition comprises, by weight, 15 % Cr, 13.6 % Co, 4.1 % Mo, 4.6 % Ti, 2.2 % Al, .01 % C, 0.007 % B, 0.07 % Zr, balance Ni. This material is forged at a temperature above the gamma prime solvus and at a true strain of at least .5. Alternately, the material may be forged below the gamma prime solvus temperature with intermediate super solvus anneals. The overaged material is then worked at a temperature below the gamma prime solvus. The resultant fine grain material is then heat treated or can be further isothermally forged prior to heat treatment to produce complex shapes.

    Abstract: A drive system for varying the diameter of a variable diameter rotor has a gear assembly associated with a single coaxial shaft (13) lower end which includes a gear set for increasing the speed of rotation of the central shaft (13) relative to the rotor drive shaft (2) to change the diameter of the variable diameter blades. A pair of brakes are used, one (37) to slow the coaxial shaft relative to the drive shaft and another (25) to lock the rotor shaft (2) and coaxial shaft (13) together for corotation during constant diameter flight conditions. Utilizing a lower gear assembly reduces hub complexity and allows the variable diameter rotor drive system to be adapted to gimballed rotors which require shaft flexibility. Since only a single shaft extends through the rotor drive shaft, hub complexity is reduced.
