  • Publication number: 20240154274
    Abstract: A power storage cell comprises an electrode assembly, a cell case, and an external terminal. The cell case has a case body and a lid. The lid has a lid body electrically charged with the same polarity as that of a positive electrode or a negative electrode, an invertible plate capable of short-circuiting between the lid body and the external terminal, and a prevention part connected to the invertible plate. The invertible plate is deformable between a normal shape and an inverted shape. The lid body has a receiving portion that receives the prevention part when the invertible plate is in the inverted shape. The receiving portion allows the prevention part to pass therethrough when the invertible plate is deforming from the normal shape to the inverted shape, and is in contact with the prevention part when the invertible plate is in the inverted shape.

  • Publication number: 20240128705
    Abstract: A gas laser amplifier includes a housing, discharge electrode pairs, and an optical resonator. The housing includes an entrance window that allows entry of a first laser beam from outside and an exit window that allows exit of the first laser beam amplified. Each of the discharge electrode pairs excites a laser gas supplied between discharge electrodes facing each other in the housing. The optical resonator causes a second laser beam to oscillate with a gain of the excited laser gas in a non-incident state where the first laser beam from outside the housing does not enter the housing through the entrance window. In an incident state where the first laser beam enters the housing through the entrance window, the optical resonator suspends the oscillation of the second laser beam.
