Title: Frequency chirp in isotopically selective photoexcitation
IPC: B01D9/00
Filed: 1978-12-20
Abstract: Method and apparatus for inducing isotopically selective photoexcitation of atoms in at least first and second energy steps. The total energy change accomplished by the two energy steps is provided with isotopic selectivity at precise resonance for the two steps. In an isotope separation system in which an environment of particles of plural isotope types is created, isotopically selective photoexcitation from laser radiation is shown to produce a great improvement in excitation efficiency where the radiation is controlled in the aggregate of plural photons to achieve precise resonance over the plurality of the degenerate energy steps. Even with multimode excitation, precise resonance is only achieved for isolated atoms, and a chirp or frequency sweep is applied to one of several excitation frequencies to insure precise resonance at least once for each atom. In the case of excitation in plural transitions from plural low-lying energy through a generally common upper transition, the chirp may be applied to the radiation producing the common upper level transition alone.

Title: Ceramic capacitors and dielectric compositions
IPC: C04B35/497
Filed: 1982-07-02
Abstract: A dielectric composition which is particularly suitable for the manufacture of ceramic capacitors, comprises lead magnesium niobate with additions of one or more lead titanate, lead stannate, or lead zirconate. The composition can be fired at a temperature between 950 DEG and 1100 DEG C., which is lower than the conventional firing temperatures of 1200 DEG to 1400 DEG C. The lower firing temperature means that, in the case of multilayer ceramic capacitors, the internal electrodes can be made of cheaper materials than previously with resultant materials and process cost savings. Some of the compositions exhibit higher dielectric constants than conventional Z5U ceramics, which means that capacitor device size can also be reduced.
