Disclosed herein is an apparatus for cable management synchronized with telescopic motion. The apparatus is configured such that cables for transmitting power or signals to a manipulator provided on a lower end of a telescopic tube and for receiving signals therefrom are wound or unwound in response to expansion or contraction of the telescopic tube. Moreover, the apparatus is configured such that the cables are prevented from being displaced from the correct positions, a noise is prevented from being generated, and the tension of each cable is adjusted even when it is in the clamped state.

An apparatus and system for separating remaining powder of hulls includes a first remaining powder separating unit to be supplied with hulls of a spent nuclear fuel subjected to a high-temperature oxidation, and to include a first brush for separating remaining powder of the hulls; a hull alignment unit to be supplied with the hulls from the first remaining powder separating unit, and to align the hulls; a second remaining powder separating unit to be supplied with the aligned hulls from the hull alignment unit, and to include a second brush for separating remaining powder adhered on an inner peripheral surface of the hulls; and a third remaining powder separating unit to be supplied with the hulls from the second remaining powder separating unit, and to separate the remaining powder remaining on the inner/outer peripheral surface of the hulls by using air.

A swing angle measuring apparatus generates feedback signals for closed loop regulation of a load swinging motion in operation of a crane. The swing angle measuring apparatus measures two-dimensional swing angles, and includes a rope fixed to a hoisting device, two laser displacement sensors, laser reflecting plates, and a rectangular box attached to a hoisting device. Two steel reflecting plates are installed on the periphery of the fixed rope. Two laser displacement sensors are installed in a rectangular box such that the heading of the sensors are configured to perpendicularly intersect the faces of the laser reflecting plates. The configuration of the displacement sensors and the reflecting plates can be reversed. The rectangular box is attached to the hoisting device, and the laser reflecting plates are placed at an offset distance away from the face of the laser displacement sensors, at which a sensor signal of 0 volts is obtained. The swing angle of the rope or cable is determined from the distance between the laser displacement sensors and the laser reflecting plates.
