Abstract: Two flow paths separated by a partition wall having a bore formed downstream of a catalyst unit provided in an exhaust pipe of an internal combustion engine. Adsorption means for adsorbing an HC component of an exhaust gas of the internal combustion engine is provided in one of the flow paths. When a temperature of the exhaust gas is above a predetermined level, the exhaust gas flows through the other flow path by means of a change-over valve. Because the bore is provided in the partition wall, the adsorption means is exposed to the exhaust gas and the HC component adsorbed by the adsorption means is easily desorbed because of the high temperature of the exhaust gas. A one-way valve which repeatedly performs an opening/closing operation due to pulsation of the exhaust gas, is provided between recirculation flow pipes.

Abstract: An exhaust gas purification apparatus has a catalyst unit provided in an exhaust pipe of an engine and an absorbent provided downstream of the catalyst unit. When the engine is in a cool state, HC emitted from the engine is absorbed by the absorbent. After the engine is warmed up, the absorbed HC is desorbed by heat of an exhaust gas and returned to an upstream side of the catalyst unit the HC by heat of an exhaust gas.

Abstract: Mixed gas of nonoxidizing gas and oxygen is blown into molten chrome steel in a vessel. The molten chrome steel is stirred by the gas and is decarbonized by the oxygen in the gas while being stirred. After the carbon potential in the molten chrome steel has been lowered, the pressure inside the vessel is reduced and the nonoxidizing gas alone is blown as the gas. Bubbles of the gas blown into the molten chrome steel become large on account of reduced pressure and exhibit sufficient stirring function. Consequently, the molten chrome steel is effectively stirred and the decarbonizing reaction is prompted.
