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.

Extreme ultraviolet light generation apparatus, extreme ultraviolet light generation system, and electronic device manufacturing method

A wheel loader is provided with an engine, an engine compartment, a top plate, an injection device, and a duct member. The engine compartment houses the engine. The top plate has a first opening section. The top plate defines the upper surface of the engine compartment. The injection device is disposed inside the engine compartment. The duct member is disposed above the injection device. The duct member is disposed below the first opening section.

Work vehicle

A wheel loader is provided with an engine compartment, a urea water injection device, a second side plate, a guiding member, and a suction part. The second side plate has a first outdoor air intake port. The guiding member is configured to guide outdoor air sucked in through the first outdoor air intake port onto the urea water injection device. The suction part sucks air into the engine compartment. The urea water injection device is disposed within an air flow produced between the suction part and the guiding member.

A wheel loader is provided with an engine compartment, a cooling compartment, a radiator, a cooling fan, a partition wall, a first duct body part, and a top plate. A first end part of the first duct body part is positioned inside the engine compartment. A second end part of the first duct body part is positioned inside the cooling compartment in front of the radiator and the cooling fan. A first outdoor air intake port formed in the top plate is formed in front of the radiator and the cooling fan.

Nozzle for a plasma arc torch

A plasma arc welding for effectively letting gases of low boiling point substances for coating a steel sheet escape, ensuring the escape of a molten metal into gaps between the steel sheets and eventually accomplishing satisfactory plasma arc welding. A hole (,) is first bored in an upper sheet (,)(or both upper and lower sheets (,and,)) quickly by using a plasma arc (,) having greater power than an appropriate welding value, and a vapor of coating substances is allowed to escape through the hole (,). Subsequently, power of the plasma arc (,) is lowered to the appropriate welding value, and the upper sheet (,) and the lower sheet (,) are welded together while a filler (,) is being supplied to fill the hole (,) and the gap (,). While boring is made or immediately after boring is finished, the size of the gap (,) is measured on the basis of the plasma arc voltage, and the feed quantity of the filler (,) is controlled in accordance with the size of the gap (,).
