<p>PROBLEM TO BE SOLVED: To gather a chip-shaped, conductive material and to given a warning on parts fracture by arranging a magnet for attracting a metal chip between positive and negative contacts being separated by a chip gap. SOLUTION: A magnet 22 is arranged between two contacts 12 and 14. When a metal chip gathers at the magnet 22 and is integrated and then a gap 18 is crosslinked by the chip, current flows between the contacts 12 and 14 and a chip detector circuit becomes a closed circuit, thus generating a warning signal using a signal means. Also, when an electric resistor is added to the chip detector circuit and the chip gathers at the gap 18 and then circuit resistance drops and reaches a preset value, a signal or other warnings are generated, thus reporting the excess of chips and the fracture of parts.</p> |
