A power generation element includes a main series magnetic circuit having a frame yoke made of magnetic material and provided with a fixed portion that is one end and a free portion that is the other end across a U-shaped bent portion, a main magnet that applies a magnetic bias to the frame yoke, and a first gap formed at a position in contact with the free portion; and an auxiliary series magnetic circuit having an auxiliary yoke made of magnetic material and attached to the frame yoke, an auxiliary magnet that gives a magnetic bias to the auxiliary yoke, a second gap formed at a position facing the first gap across the free portion, the frame yoke, the main magnet, and the first gap. The amount of change in a main magnetic flux passing in a coil wound around the frame yoke increases when the free portion vibrates due to application of an external force and a magnetic resistance of the first gap and a magnetic resistance of the second gap increase or decrease reciprocally.

Abstract: The present invention relates to a cyber-physical system for optimizing a simulation model for chemical mechanical polishing based on actual measurement data of chemical mechanical polishing. The chemical mechanical polishing system includes a polishing apparatus (1) for polishing the workpiece (W) and an arithmetic system (47). The arithmetic system (47) includes a simulation model including at least a physical model configured to output an estimated polishing physical quantity including an estimated polishing rate of the workpiece (W). The arithmetic system (47) is configured to: input polishing conditions for the workpiece (W) into the simulation model; output the estimated polishing physical quantity of the workpiece (W) from the simulation model; and determine model parameters of the simulation model that bring the estimated polishing physical quantity closer to a measured polishing physical quantity of the workpiece (W).

Abstract: A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.
