    摘要: A method of producing a cam lobe piece of an assembled camshaft in a valve operating system for an internal combustion engine. The method comprises (a) forming a profile of the cam lobe piece by upsetting a material under forging to obtain an intermediately formed body; (b) piercing a central portion of the intermediately formed body to form a shaft bore; and (c) ironing an inner peripheral surface of the pierced intermediately formed body to form unevenness at the inner peripheral surface, all accomplished by cold working. The material at the forming the profile of the cam lobe piece has a first section located on a side of a cam nose of the cam lobe piece, and a second section located longitudinally opposite to the first section. The material has a thickness which gradually increases in a direction from the second section to the first section.

    摘要: A waste object containing oil has a first opening formed therein at an upper portion thereof and a second opening positioned below the first opening. The first and second openings are connected to a recovery tank. Hot water of a predetermined temperature is held in the recovery tank and is caused to accumulate inside the waste object via the second opening. Oil that has floated upwards is recovered in the recovery tank via the first opening.

    摘要: An apparatus for demolishing an oil-containing industrial waste object, includes a turntable for supporting thereon of an oil-containing industrial waste object, a sealed enclosure mounted above the turntable for gas-tightly enclosing the industrial waste object, a fluid pumping device for sucking a fluid medium out from the sealed enclosure, and a plasma arc torch fitted inside the sealed enclosure for radiating the industrial waste object with a plasma. After the fluid medium within the sealed enclosure has been sucked out by the fluid pumping device, an inert gas is supplied into the sealed enclosure through an inert gas supply port. The industrial waste object is then irradiated by a plasma from the plasma arc torch while being rotated together with the turntable, to thereby cut the industrial waste object horizontally.
