Abstract: In a method of controlling a heating cooking apparatus, when a generated steam volume at a forced finish time Tn?1 determined based on a minimum volume-minimum steam curve does not reach a minimum steam volume B1 determined based on a slowly rising maximum volume-maximum steam curve, the generated steam volume is smaller than in the case of a food having a maximum weight. Therefore, it can be judged that heating is performed in a no-load condition with an exceedingly small generated steam volume, and the operation of the heating cooking apparatus is forcedly stopped. When a generated steam volume at a maximum detection time Tm+1 does not reach a standard steam volume A determined based on the maximum volume-maximum steam curve, it is judged that a large amount of food exceeding a maximum amount is being heated and the operation of the heating cooking apparatus is forcedly stopped.

Abstract: The present invention generally comprises a method for dynamically controlling the temperature of a solar cell substrate during microcrystalline silicon deposition. In amorphous silicon/microcrystalline tandem solar cells, microcrystalline silicon may be deposited using a higher power density and to a greater thickness than amorphous silicon. The higher the power density applied, the faster the deposition may occur, but the temperature of the deposition may also increase. At high temperatures, the likelihood of dopant diffusing into the intrinsic layer of the solar cell and damaging the cell is greater. By dynamically controlling the temperature of the susceptor, the substrate and hence, the dopant can be maintained at a substantially constant temperature below the value at which the dopant may diffuse into the intrinsic layer. The dynamic temperature control permits the microcrystalline silicon to be deposited at a high power density without damaging the solar cell.
