Abstract: A pressurizing system capable of actively varying and adjusting the pressure applied to a cell of an all-solid-state battery includes: a pressurizing mechanism provided to pressurize an all-solid-state battery and driven to adjust and vary the pressure applied to the all-solid-state battery; a driving device operated to drive the pressurizing mechanism; and a controller controlling the operation of the driving device so that the pressure to pressurize the all-solid-state battery can be adjusted and varied by the above pressurizing mechanism. When the all-solid-state battery is charged or discharged, the controller controls the operation of the driving device based on a pressure change rate so that the pressure for pressurizing the all-solid-state battery may be adjusted and varied according to the pressure change rate determined based on the state information of the all-solid-state battery.

Abstract: An all-solid-state battery having an increased lifespan is equipped with a pressure pad layer. More particularly, the all-solid-state battery includes a unit cell and a pressuring pad layer. The unit cell is composed of a cathode, an anode, and a solid electrolyte layer positioned between the cathode and the anode. The pressurizing pad layer is positioned on each side of the unit cell and includes a non-porous upper layer, a non-porous lower layer, and a porous core layer positioned between the non-porous upper layer and the non-porous lower layer.

Abstract: In the case of a gas in which several gases are mixed, a type and concentration of the gas may be incorrectly measured when measured using only an optical band-pass filter. The invention of the present application is directed to providing a technology in which a plurality of broadband band-pass filters having overlapping regions are provided to calculate a magnitude of absorption for each wavelength band for light passing through each broadband band-pass filter, thereby identifying the presence of a gas of interest and the presence of a gas other than the gas of interest.

Abstract: The present invention relates to a foldable gas burner, in which a distance between a combustion part of a cooking part and a gas supply part is maximized when the gas burner is used in order to improve safety, and the cooking part and the gas supply part overlap each other when the gas burner is stored in order to minimize a volume, particularly, a length of the gas burner, thereby enabling the gas burner to be easily carried, stored, and received. Meanwhile, in consideration of a problem with safety such as prevention of a gas accident, there is a need for a safety means capable of automatically cutting off a supply of gas to the cooking part with high reliability when the supply part and the extension part overlap each other.

Abstract: Disclosed are a method and apparatus for composing a plurality of images of the celestial bodies. The method and apparatus can compose a plurality of images using various pieces of information associated with the plurality of images and a time interval during the plurality of images are taken, such that objects are accurately matched with no afterimage.
