Abstract: A multilayer electronic component has a body and a non-conductive resin layer. The non-conductive resin layer includes a body cover portion disposed in a region of an external surface of the body in which an electrode layer of an external electrode is not disposed, and an extending portion extending from the body cover portion between the electrode layer and a conductive resin layer of the external electrode, to thereby suppress arc discharge, improve bending strength, and improve moisture resistance.

Abstract: 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.
