  • MINIATURIZED PIEZOELECTRIC ACCELEROMETERS
    Publication number: 20110296918
    Abstract: The miniaturized piezoelectric accelerometer includes a support frame (102) having a cavity (104) and a seismic mass (108) supported by a plurality of suspension beams (110) extending from the support frame (102). Each of the suspension beams (110) has a piezoelectric thin film coated on a top surface thereof, with a pair of inter-digital electrodes (114) deposited on an upper surface of each piezoelectric thin film. The presence of acceleration excites bending and thus strain in the piezoelectric thin film, which in turn causes electrical signals to be generated over terminals of the electrodes (114). To collect constructively the output of the electrodes (114), one terminal of each of the electrodes (114) is routed to and electrically connected at a top surface (308) of the seismic mass (108).

  • T222 production by powder metallurgy
    Patent number: 5940675
    Abstract: Powder metallurgy production of T222 alloy affording properties comparable to melt derived T222, but at higher yields and lower costs, is enabled by blending component powders of minus 325 mesh and sintering at 2,400.degree. C. in three sinter steps and utilizing a slow ramp up in the first sinter step and cold isostatic pressing prior to the first sinter step and isostatic press densification in conjunction with at least the first sinter step.
