Abstract: A lithography apparatus comprises a wafer stage, a cable configured to be bent as the wafer stage moves, a first support configured to prevent the cable from sagging, and to support the cable to maintain a bent state of the cable when the cable moves, a first rail installed on a first side of the cable, and including curved track extending in a direction from a lower portion of the cable toward an upper portion of the cable, wherein the first rail includes a concave first surface, a second rail installed on a second side of the cable opposite the first side of the cable, and including curved track extending in the direction from the lower portion of the cable toward the upper portion of the cable, wherein the second rail includes a concave second surface.

Abstract: A device for carrying artillery shells, each shell having a cylindrical body and a conical head, is disclosed. The device includes an upper body and a lower body. A gripper assembly is connected to the lower body and has an inner circumferential surface corresponding to the cylindrical body. A driving unit pivots the gripper assembly about an axis. A shell-head stopping unit is connected to the lower body at a position which may be adjusted along the length of the lower body. The shell-head stopping unit receives the conical head of a shell to hold the shell in a set position. Also included is a shell-rear stopping unit connected to the gripper assembly and elastically biased upward with respect to the inner circumferential surface of the gripper assembly. The shell-rear stopping unit holds the rear end of the shell in the gripper assembly.
