Abstract: An embodiment of the present invention provides a pull-out system comprising: at least two slide rails each having a fixed rail, a middle rail slidably arranged on the fixed rail, and a movable rail slidably arranged on the middle rail; and a synchronization means for synchronizing the movement of the movable rail, wherein the synchronization means comprises a roller unit, a synchronization bar connected to the roller unit, and a deflectable element having an end portion fixe to the roller unit and an opposite end portion connected to the movable rail, and the movable rail is configured to move as much as the amount of rotation of the roller unit.

Abstract: Proposed is a hinge device having tension maintaining function, the hinge device including: a winding member affixed to a main body of a mounted structure having an inner space formed therein; a hinge member affixed to a door that opens or closes the inner space and mounted on the winding member so as to enable the door to be pivotable; and a tension member having one end affixed to the winding member and the other end affixed to the hinge member, such that the tension member transmits a tension to the door when opening and closing the door.

Abstract: A memory device includes an input unit configured to receive a plain text and output plain blocks and CTS plain block, a multi-core unit including a plurality of encryption/decryption cores configured to encrypt each of the plain blocks provided from the input unit and output cipher blocks in accordance with control of an encryption/decryption core control unit, a CTS core unit including a CTS core configured to encrypt the CTS plain block provided from the input unit into a CTS cipher block, and an output unit configured to receive the cipher blocks and the CTS cipher block and output a cipher text. The CTS plain block is generated through a CTS calculation based on the plain text.
