Abstract: The Rh content by percentage in an HC absorbent catalytic converter provided in an exhaust pipe is greater than the Rh content by percentage in an upstream three-way catalyst. In this way, even when HC which has been temporarily absorbed is emitted in an atmosphere and the exhaust gas becomes rich, the HC absorbent catalytic converter displays improved oxidization and removal of HC due to the high content by percentage of Rh which has a high HC conversion ratio in rich atmospheres. There is no necessity to control the air-fuel ratio to a strongly lean ratio and so HC removal can be improved while maintaining suppression of NOx emissions.

Abstract: A heating-type vacuum press device which has a small vacuum isolation chamber in which pressing is performed under vacuum without damage to seal packing, while heating. A lower fixed frame and an upper movement frame constitute a wall portion of the isolation chamber. A gas-tight sliding mechanism ensures gas-tightness between the lower fixed frame and the upper movement frame. Thereby, the isolation chamber is formed in a space defined by the lower fixed frame, the upper movement frame, a base and a fitting plate. The lower fixed frame surrounds a receiving table equipped with a heater for a workpiece, and is arranged on the base such that the lower fixed frame is spaced from the receiving table. The upper movement frame is hanged from the fitting plate such that the upper movement frame is spaced from a pressing plate equipped with a heater, and surrounds the pressing plate.
