  • METHOD AND SWAPPING TOOL
    Publication number: 20230400772
    Abstract: A method for swapping an optical system, such as a DUV mirror, of a projection exposure apparatus, comprises: a) raising the optical system along a centre axis of the optical system so that mount struts of the optical system pass out of contact with frame struts of a frame carrying the optical system; b) rotating the optical system about the centre axis so that the mount struts are arranged between the frame struts; c) lowering the optical system along the centre axis; and d) shifting the optical system perpendicularly to the centre axis so that the optical system is moved out of a housing.

  • Combustion method for a reciprocating piston internal combustion engine
    Patent number: 7874277
    Abstract: A reciprocating engine includes a combustion chamber, and a gas exchange inlet valve and a gas exchange outlet valve for a charge cycle. The method introduces an inlet gas into the combustion chamber in an intake phase; introduces a primary quantity of fuel into the combustion chamber during the intake phase and/or a compression phase; compresses the inlet gas and the fuel in the compression phase; ignites a mixture of inlet gas and fuel formed in the combustion chamber; and expands and discharges an exhaust gas formed by the combustion in an expansion phase. A pilot quantity of fuel is introduced into the combustion chamber before the primary quantity of fuel is introduced.
