Testing device utilizes the change in pressure about a bias or reference pressure level produced by displacement of a center-driven piston in a closed cylinder. Closely controlled pneumatic pressure waves allow testing under dynamic conditions.
Thin film heat transfer gauge for use in hypersonic shock tunnel - contour, calibration of thin film sensors, and cost reduction
Michelson interferometer and laser source for measuring oscillatory motion for calibration of miniature accelerometers
Charge transport in thin polymer films based on field emission or thermal emission
Charge transport mechanism in thin silicon nitride films
Magnetic tape transport includes a common drive for both the tape drive capstans and the rotating record/reproduce heads. Speed of the drive may be varied within a preselected range, but, once selected, remains constant so head and capstan are driven in synchronization and at constant speed.
Thin film transport in polymer dielectrics, fabrication of semiconductor devices having digital or discontinuous responses, and chemical vapor deposition of exotic dielectric films
Dielectrics, titanium dioxides, and vapor deposition of thin films for digital metal-insulator-silicon tranducers
Insulated gate field effect transistors using cadmium selenide or telluride as piezoelectric semiconductor material
Explore the source record for details and available documents.
Potential electrical response of p-n junction to mechanical strain
Device, under longitudinal bias, responds to pressure input with a transverse voltage proportional to the pressure signal. In the absence of a signal, the transverse voltage is zero even with bias, and, regardless of temperature, if the transverse contacts are appropriately positioned along a zero-pressure equipotential.
Thin film titanium dioxide by high temperature vapor deposition
Charge transport mechanism in metal semiconductor polymer thin films
Cadmium sulfide photodielectric effect at cryogenic temperatures with bibliography
Dielectric properties of thin films of polymerized oil-metal-silicon structures
Determining sway of buildings by low frequency device using pendulum
Melatonin biosynthesis, discussing regulation by light and sympathetic nerves, daily pineal rhythms, estrous rhythms and ovarian hormones
