  • Publication number: 20060155587
    Abstract: In compliance with 37CRF 1.72(b) the overall Business Method Design is to equip every vehicle insured, with the most safety factors available to prevent accidents, prevent thefts, and maintain the highest level of maintenance to every vehicle, so that efficiency and emissions always comply to EPA Rules and Regulations. In addition to our unique method of insuring vehicles, the insured will be able to get total vehicle sales and every kind of service from A to Z at the location of his General Insurance Agents sales and service office. Also, an insured will never have to drive a wrecked vehicle. The wrecked vehicle will be taken apart and the insured will have his vehicle replaced with a new or equivalent vehicle to his satisfaction.

  • Publication number: 20050063894
    Abstract: The present invention provides fluoride lens material crystals for VUV optical lithography systems and processes. The invention provides a fluoride optical lithography crystal for utilization in below 200 nm photolithography methods, for example 157 nm optical microlithography elements which manipulate below 193 nm optical lithography photons. The invention particularly pertains to mixed metal fluoride crystals; for example crystals comprised of an alkali metal fluoride and an alkaline earth metal fluoride; crystals comprised of a first alkaline metal fluoride and a second alkaline earth metal fluoride in which the two metals are different; and crystals comprised of an alkaline earth metal fluoride and lanthanum fluoride.

  • Publication number: 20020011202
    Abstract: A method and apparatus for producing crystals that minimizes birefringence even at large crystal sizes, and is suitable for production of CaF2 crystals. The method of the present invention comprises annealing a crystal by maintaining a minimal temperature gradient in the crystal while slowly reducing the bulk temperature of the crystal. An apparatus according to the present invention includes a thermal control system added to a crystal growth and annealing apparatus, wherein the thermal control system allows a temperature gradient during crystal growth but minimizes the temperature gradient during crystal annealing. An embodiment of the present invention comprises a secondary heater incorporated into a conventional crystal growth and annealing apparatus. The secondary heater supplies heat to minimize the temperature gradients in the crystal during the annealing process. The secondary heater can mount near the bottom of the crucible to effectively maintain appropriate temperature gradients.
