  • Patent number: 11363705
    Abstract: An extreme ultraviolet light generation apparatus may include a chamber device, a concentrating mirror, a central gas supply port configured to supply gas along a focal line passing through a first focal point and a second focal point from the center side of the reflection surface, and a first peripheral gas supply port disposed at a peripheral portion of the reflection surface and configured to supply gas in a direction from the outer side of the reflection surface toward the inner side of the reflection surface. The first peripheral gas supply port may supply gas, when viewed along the focal line, in an inclined direction inclined to a tangential direction side of the peripheral portion at the peripheral portion where the first peripheral gas supply port is located with respect to a first straight line passing through the first peripheral gas supply port and the focal line.

  • Patent number: 11358825
    Abstract: A post-processing apparatus includes a binding device, a closing device, a driver, and a changeover switch. The binding device binds a sheet bundle. The closing device closes an entrance to a binding position at which the binding device binds the sheet bundle. The driver moves the closing device to a closing position to close the entrance. The switch performs switching to implement a state in which the binding device is able to bind the sheet bundle when the closing device moves to the closing position. The closing device includes an avoidance operation portion to move to the closing position to operate the switch, and a drive coupler coupled to the avoidance operation portion to move the avoidance operation portion to the closing position. A coupling state between the avoidance operation portion and the drive coupler is released when movement of the avoidance operation portion to the closing position is prevented.
