Abstract: A lithium ion battery particularly configured to be able to discharge to a very low voltage, e.g. zero volts, without causing permanent damage to the battery. More particularly, the battery is configured to define a Zero Volt Crossing Potential (ZCP) which is lower than a Substrate Dissolution Potential (SDP) to thus avoid low voltage substrate damage.

Abstract: An image display device is constructed by a display memory, a sprite attribute table, a sprite rendering processor and an animation execution engine. The display memory stores image data to be displayed on a display. The sprite attribute table stores attribute data representing a display attribute of a sprite which is a component of the image data. The sprite rendering processor executes a drawing process for reflecting image data of the sprite to the image data stored in the display memory according to the attribute data stored in the sprite attribute table. The animation execution engine reads an animation execution program including both attribute data to be transferred and a table write command of the attribute data from an external memory, and executes the animation execution program to transfer the attribute data to the sprite attribute table according to the table write command.

Abstract: A nonaqueous secondary electrolytic battery comprising an electricity-generating element formed by spirally winding a laminate of a positive electrode plate, a separating material and a negative electrode plate, and an electrolytic solution with which the separating material, if it is a separator, is impregnated. The electricity-generating element is sealed in a battery case formed by a resin-laminated sheet comprising a metal layer as a barrier layer. Only a pair of lead terminals are drawn to the exterior of the battery case. The resin sheet comprises an oriented resin layer laminated on both surfaces of the metal layer. The inner heat-fused layers are opposed and heat-fused to each other. A molten and solidified resin mass is formed protruding from the inner end of the welded portion toward the inner space of the battery by 0.1 mm or more. Alternatively, the welded portion is formed thinner at the outer end thereof than at the inner end thereof.

Abstract: A feedthrough is insulated and hermetically sealed by brazing a ceramic disk to a case cover and by brazing the top surface of the ceramic disk to the bottom surface of a feedthrough pinhead. Using this technique instead of forming a compression seal, the surface area for bonding is increased, increasing bond strength. The ceramic disk electrically insulates the feedthrough pin from the cover, and provides a large surface area for mechanically sealing the cell with the braze. Considering the small size of many cells, this increased surface area is important for getting a good seal and increasing bond strength. This design also creates a longer fluid path, providing greater hermeticity. Furthermore, a greater range of component material combinations is available because CTE compatibility limitations of the feedthrough pin, cover, and insulator are minimized. This feedthrough is applicable to broad array of applications and numerous material combinations.

Abstract: The battery includes a positive electrode having a first active material on a positive substrate. The first active material includes LiNixCo1-x-yMyO2 wherein M is chosen from the group consisting of Mn, Al, Mg, B, Ti, and Li, and wherein 0.5?x?1 and 0?y?0.3. The battery also includes a negative electrode having a second active material on a negative substrate. The second active material includes carbon. The negative electrode is susceptible to damage when a voltage exceeding a Damage Potential Threshold (DPT) is applied to the negative electrode. The DPT is lower than the maximum positive operating potential of the battery. The positive and negative electrodes define a Zero Volt Crossing Potential (ZCP) relative to a reference level when the voltage between the positive electrode and the negative electrode is zero. The positive electrode and the negative electrode are configured such that the value of the ZCP is less than the value of the DPT at a predetermined temperature.
