摘要： A thermoacoustic refrigerator having a relatively small size which utilizes one or more piezoelectric drivers to generate high frequency sound within a resonator at a frequency of between about 4000 Hz and ultrasonic frequencies. The interaction of the high frequency sound with one or more stacks create a temperature gradient across the stack which is conducted through a pair of heat exchangers located on opposite sides of each stack. The stack is comprised of an open-celled material that allows axial, radial, and azimuthal resonance modes of the resonator within the stack resulting in enhanced cooling power of the thermoacoustic refrigerator.

摘要： Various articles of manufacture, such as electrosurgical scalpels, razor blades, electronic components and mechanical components having a quasicrystalline AlCuFe alloy film less than about 10,000 Å thick. Such articles of manufacture may be formed by depositing (in sequence) on a substrate through radio frequency sputtering a stoichiometric amount of each respective alloy material and then annealing those layers to form the film through solid state diffusion.
