    摘要: The inspection conditions of a known inspection apparatus necessary for inspection are such that wafers are individually prepared for respective layer types and layer thicknesses, and standard particles having different sizes are applied to all of the wafers. Moreover, the wafers to which standard particles have been applied and which have been prepared for the respective layer types and layer thicknesses are inspected by the inspection apparatus to determine the optimal inspection conditions for the respective layer types and layer thicknesses. Therefore, there are problems that it requires long time and involves high cost to determine the inspection conditions. In the invention, the relation between the layer thickness and the scattering intensity in the inspection apparatus is calculated. The scattering intensity is divided into a plurality of intensity regions, and the inspection conditions optimized for the respective divided regions are determined. The inspection conditions are shared in each divided intensity region, whereby the time and cost necessary to determine the inspection conditions can be dramatically reduced.

    摘要: A catalyst deterioration diagnosis system performs a diagnosis of deterioration of the oxidation catalyst based on a high-temperature-inflow-condition exhaust gas temperature and a low-temperature-inflow-condition exhaust gas temperature. The high-temperature-inflow-condition exhaust gas temperature is a temperature detected by a temperature sensor while the temperature of the exhaust gas that flows into the oxidation catalyst is in a high temperature region H while the reducing agent is supplied from the reducing agent supply means into the exhaust gas that flows into the oxidation catalyst. The low-temperature-inflow-condition exhaust gas temperature is a temperature detected by the temperature sensor while the temperature of the exhaust gas that flows into the oxidation catalyst is in a low temperature region L while the reducing agent is supplied from a reducing agent supply means into the exhaust gas that flows into the oxidation catalyst.

    摘要: A temperature increasing degree of the catalytic outflow exhaust temperature at the time the exhaust air-fuel ratio is changed to the rich side is found in respect to each of a plurality of the catalytic inflow exhaust temperatures. A grade (S) of the temperature increasing degree is found based upon the inflow exhaust temperature and the temperature increasing degree to determine degradation of the catalyst based upon at least one of a maximum value (Smax) of the grade and the inflow exhaust temperature (Tinmax) corresponding to the maximum value. An accurate catalyst degradation diagnosis can be carried out since not only the temperature increasing degree but also the inflow exhaust temperature are taken into account.
