  • Patent number: 6900781
    Abstract: A plasma display having a discharge cell, the emission efficiency of which is improved by generating first and second discharges with one sustaining pulse. A first discharge is generated by increasing a voltage up to a maximal value through a LC resonance formed by a recovery coil and a panel capacitor. A second discharge is generated by connecting the panel capacitor to a power supply when the voltage falls a predetermined amount below the maximal value, thereby increasing the voltage to a predetermined level above the maximal value.

  • Patent number: 6777134
    Abstract: A negative electrode for a rechargeable battery including: a current collector, a first layer containing a conductive material to occlude and release lithium ion, the first layer formed on the current collector, a second layer containing a metal selected from lithium and lithium alloy, the second layer formed on the first layer, and a third layer containing a lithium ion conductive material, the third layer formed on the second layer. The third layer prevents the lithium and/or the lithium alloy in the second layer from being in contact with the electrolyte and smoothly feeds the lithium to the second layer to improve the efficiency of the negative electrode. The first layer can occlude and release the part of the lithium to be occluded and released, thereby reducing the volume change of the second layer. Such a structure of the negative electrode enables us to enhance cycling efficiency, and to attain long cycle life and good safety.

  • Publication number: 20040149710
    Abstract: A heat roller has a cylindrical sheet-like heating element, an inner tube and an outer tube. The sheet-like heating element has a resistance member embedded into an insulating member. The outer tube has a non-linear shape seen in an axial direction. The heat roller is fabricated by supplying pressurized fluid to the inner tube for expanding the inner tube, sheet-like heating element and outer tube toward a die. The die has a non-linear inner shape seen in the axial direction. Therefore, the outer tube of the fabricated heat roller has a non-linear shape. Further, an edge section of the inner tube can simultaneously be formed into a desired shape.
