A heat shield plate for a substrate annealing apparatus is provided with a horizontally supported flat-plate-like substrate, a heaterpositioned above the substrate to heat the upper surface of the substrate with radiation heat, and a heat shield platehorizontally movable between a shielding position where the substrate is shielded from heater and an open position out of the shielding position. The heat shield plateis composed of a structural membermade of a low thermal expansion material (carbon composite material) which is hardly deformed due to a temperature difference in the shielding position, and a heat insulating memberwhich covers the upper surface of the structural member and keeps the surface at an allowable temperature or below.

A degradation estimating apparatus for an unburned fuel component adsorption catalyst, which is connected with an internal combustion engine and has an unburned fuel component adsorbent and an oxygen storage component is provided. The apparatus includes a degradation estimating unit for making estimation for a degradation of the unburned fuel component adsorption catalyst on the basis of a first term and a second term. The first term is from the cancellation of the fuel supply to detecting a variation of an upstream side air-fuel ratio occurring due to the increase of the reductant quantity in the exhaust gas. The second term is from the cancellation of the fuel supply to detecting of a variation of the downstream side air-fuel ratio due to an increase of the reductant quantity.

The exhaust gas purification apparatus for an engine comprises, a catalytic converter provided in an exhaust path of the engine and including a carrier, an HC absorbent, an HC purifying catalyst, and a transition metal, and a control apparatus for controlling operation of the engine, the control apparatus including an HC desorption timing estimation section for estimating a timing at which the HC is desorbed from the HC absorbent and a control section for controlling an air fuel ratio upon starting of the engine to a ratio richer than a stoichiometric air fuel ratio to start operation of the engine and changing over the air fuel ratio to a ratio leaner than the stoichiometric air fuel ratio at the timing at which the HC is desorbed based on an output of the HC desorption timing estimation section.
