摘要： PROBLEM TO BE SOLVED: To provide a pendulum type vibration damper that can easily adjust a natural frequency, and can allow a maximum value of the natural frequency to be set as large as possible when a weight can be rotated around its center of gravity. SOLUTION: Each one end of pendulum arms 7, 7 on the side of a weight 9 is bent outward, and at each one of the bent portions, weights 20, 20 for loading are attached. The weights 20 for loading are composed of a plurality of weights with different sizes (mass) and are fixed to the pendulum arms 7, 7 using fastening parts 21, 21 such as screws that can easily be fastened or unfastened. By changing the numbers or the mass of the weights 20, 20 for loading, the adjustment of the natural frequency of a pendulum type dynamic vibration damper is enabled.

摘要： PROBLEM TO BE SOLVED: To control a conveying state of a non-magnetic material in the conveying device of the non-magnetic material for conveying the non-magnetic material using a roller. SOLUTION: When the non-magnetic material 10 conveyed by the roller 11 displaces to an alternating electromagnet 20 side due to vibration, bending, or chamber, for example, a current controller 22 supplies alternating current to the alternating electromagnet 20. The alternating current is supplied to the alternating electromagnet 20, thereby generating alternating magnetic field passing through the non-magnetic material 10 on the alternating electromagnet 20. A repulsion force for avoiding the non-magnetic material 10 occurs between eddy current on the non-magnetic material 10 induced by the alternating magnetic field and the alternating magnetic field. The current controller 22 controls a conveying state of the non-magnetic material 10 by adjusting strength of the repulsion force, by controlling the alternating current supplied to the alternating electromagnet 20 based on a detected value from a distance sensor 21.

摘要： PROBLEM TO BE SOLVED: To provide a powder feed device by which the feed of powders can be controlled more precisely. SOLUTION: The powder feed device supplies an asymmetrical waveform signal to a voice coil motor 2, a trough 4 is vibrated by the signal, and the powders 6 are dropped from the discharge port 5B of the trough 4 so as to be fed. A door plate 21 which is urged by a torsion spring coil is installed on the side of the discharge port 5B of the trough 4. The door plate 21 opens the discharge port 5B when the powders 6 are fed, and it is closed when the feed of the powders 6 is stopped. As a result, when the trough 4 is stopped and even when the powders 6 on the trough 4 collapse, the door plate 21 prevents the powders 6 from dropping from the discharge port 5B.
