    摘要: An electron emitting, barium hafnate material for arc discharge lamp electrodes is manufactured by the method comprising the steps of: forming a mixture of barium carbonate and hafnium oxide in a 48 to 52 mole ratio; adding the mixture to a suitable carrier to form a slurry; ball milling the slurry for about 2 hours to form a powder mix; drying the powder mix; firing the dried powder mix in air at about 1500.degree. C. for about 22 hours to produce a product; and vibration milling the product in methanol with zirconia media to produce the barium hafnate. The latter material is then preferably vacuum impregnated into a tungsten electrode and hydrogen fired to produce a single phase barium oxide/hafnium oxide compound.

    摘要: A high pressure sodium vapor discharge device including a polycrystalline alumina arc tube which contains a fill including sodium and mercury is disclosed. An electrode is disposed at each end of the arc tube, and an emissive material including an oxygen getter, such as, zirconium and/or niobium, and thorium dioxide is coated on at least one of the electrodes. The improved emissive material coating reduces the rate of sodium loss from the arc tube and inhibits loss of luminosity due to discoloration of the arc tube.

    摘要: This invention provides a universal interface system that is capable of launching software applications across operating system platforms. For example, the universal interface system allows a computer using a Microsoft Windows operating system to launch and execute software applications that were written for a UNIX operating system environment. Conversely, the universal interface system allows software applications written for a Linux operating system environment to be launched and operating in a Sun Solaris operating system environment. The universal interface system may interface between the BIOS and the operating system or operate on top of the operating system.
