  • Method to obtain contamination free laser mirrors and passivation of these
    Publication number: 20050153470
    Abstract: A method to obtain contamination free surfaces of a material chosen from the group comprising GaAs, GaAlAs, InGaAs, InGaAsP and InGaAs at crystal mirror facets for GaAs based laser cavities. The crystal mirrors facets are cleaved out exposed to an ambient atmosphere containing a material from the group comprising air, dry air, or dry nitrogen ambients. Any oxides and other foreign contaminants obtained during the ambient atmosphere exposure of the mirror facets are removed by dry etching in vacuum. Thereafter, a native nitride layer is grown on the mirror facets by treating them with nitrogen.

  • Induction devices with distributed air gaps
    Patent number: 6885273
    Abstract: A distributed air gap material for a induction device in power systems for minimizing fringe losses, mechanical losses and noise in the core The distributed air gap material occupies a selected portion of the core and is formed of a finely divided magnetic material in a matrix of a dielectric material particles. The air gap material has a zone of transition in which the permeability values vary within the air gap material.

  • Multiphase induction device
    Publication number: 20050030140
    Abstract: An induction device, such as a transformer or reactor, which includes windings of different phases arranged around magnetic core limbs. The magnetic core limbs are connected by at least one body formed from magnetic particles in a matrix of a dielectric material. The device can also be substantially spherical or cylindrical. Regulating windings mounted on inner and outer magnetic core parts may be transferable between the inner and outer magnetic core parts.
