Abstract: An exhaust purifying apparatus is provided, that can be manufactured at low manufacturing costs and is capable exhibiting high exhaust purifying performance. The exhaust purifying apparatus includes an exhaust passage, and an exhaust purifying member disposed in the exhaust passage. The exhaust purifying member is made of stainless steel. The surface of the stainless steel material is not covered with a catalyst coat containing a catalyst component, so that the surface of the stainless steel material is brought into contact with exhaust. The exhaust purifying member is made of precipitation hardening stainless steel and/or austenitic stainless steel.

Abstract: An engine capable of reducing the content of hydrocarbon in exhaust gas is provided. When viewed parallel to cylinder center axes, tangential virtual lines extending from endpoints of curved port central axes along tangent lines of the endpoints pass intake valve ports, straight port central axes extending from the endpoints of the curved port central axes are further away from a partition wall than the tangential virtual lines, and intake air bent through curved ports passes straight ports and is sucked through the intake valve ports along the wall between the cylinders.

Abstract: A spark-ignition engine capable of reducing the content of hydrocarbon in exhaust gas is provided. When viewed from a direction parallel to a cylinder center axis, given a central virtual line passing a squish area maximum-width section and the center of a combustion chamber recessed section, and one area a and the other area b divided by the central virtual line, an intake valve port or an exhaust valve port is opened in one area of any opposed section of opposed sections of the combustion chamber recessed section. A spark-plug attachment hole is formed in the other area of the opposed section, such that, when viewed from the direction parallel to the cylinder center axis, a spark discharge section at a tip of a spark plug does not overlap the central virtual line.

Abstract: A shape scrap processing apparatus adapted to be situated next to a conveying table for conveying a continuous shape cut in a regular size. The apparatus comprises: conveying means for conveying shape scraps, which are discharged from the conveying table, intermittently by a regular length at a time in a longitudinal direction; pressing means disposed contiguously to the conveying means downstream thereof, and operable while the conveying of the shape scraps is stopped, for pressing the shape scraps into a regular size; cutting means disposed side by side to the pressing means for cutting the shape scraps into a regular size in response to the operation of the pressing means; and discharging means for discharging the cut scraps pressed by the pressing means and cut by the cutting means.

Abstract: A slat for a transporting device for an extruded article of aluminum or an aluminum alloy in which only a worn-out portion of a heat-resistant member may be exchanged easily. The slat includes an elongated base member secured to the transporting device for the extruded article, subsidiary heat-resistant members removably mounted at terminal ends of the base member, and a main heat-resistant member arranged between the subsidiary heat-resistant members.
