A reporting system is described herein that allows a report author to declare data reporting structures that specify to a reporting application how to dynamically categorize data with changing or potentially unknown characteristics. A compression element is also provided that is attached to the internally-threaded rotatable nut. The light-emitting pattern surface includes a light-emitting part in which the light-emitting patterns are formed; and an edge part which extends along the four edge surfaces to enclose the light-emitting part and in which at least one fixing groove is formed to fix the LGP. A control moves the blotting away from the carrier depending on a change in the detected optical properties. The switching unit switches cylindrical coordinate control for controlling the arm unit such that a trajectory of the hand overlaps with any one of lines radiating from the rotation axis and rectangular coordinate control for controlling the arm unit such that the trajectory of the hand overlaps with none of the lines at a predetermined timing. The antenna elements are coordinated to function as an active phased array capable of finding and executing a resonate mode of a target.
