Abstract: A method and apparatus for nucleation and growth of diamond by hot-filament DC plasma deposition. The apparatus uses a resistively heated filament array for dissociating hydrogen in the reactant gas. For two sided diamond growth, configurations of substrate-hot filament-grid-hot filament-substrate or substrate-hot filament-hot filament-substrate configuration are used.

For this and the other electrode configurations, the grid electrode is positively biased with respect to the hot filaments to maintain a plasma. The plasma potential gradient across the grid and the hot-filament draws ions from the plasma towards the filaments. To further increase deposition rates, the filament array is biased negatively with respect to the substrate holder so that a DC plasma is also maintained between the substrate and filament array.

Abstract: Air/fuel and ignition control of engine are used to more rapidly heat-up a catalytic converter. A control system generates a fuel command for fuel delivery to the engine based upon at least an amount of air inducted into the engine. The fuel command is corrected by a correction value so that the exhaust gas mixture is shifted more closely to the preselected air/fuel ratio.

At engine shut-off the difference between the warm correction values and the reference table are stored in an offset correction table. This offset correction table is then used during the next engine cold start to schedule the open-loop air/fuel ratio by using the cold adaptive table values which have been modified by the values stored in the corresponding cells of the offset correction value table.
