Latest Patents

One of Matsushige's latest patents is a scan device for microscope measurement instruments. This device features a probe needle that is successively moved to multiple measurement points within a sample's measurement region. It measures the z-displacement amount while maintaining a constant vibration amplitude of a cantilever through feedback control of a piezoelectric element. Additionally, a vertical displacement control unit ensures a consistent distance between the probe needle and the sample based on frequency shifts detected by a frequency detection unit. This adaptive measurement technique significantly reduces unnecessary measurement time, improving throughput compared to conventional methods.

Another notable patent is the apparatus and method for obtaining a magnetic force measurement field. This invention allows for the acquisition of a magnetic force image above a sample with magnetic domains. By measuring in a plane away from the primary measurement plane, Matsushige's method calculates a magnetic force gradient image. The resulting three-dimensional field provides high accuracy in assessing the state of magnetic domains at the sample's surface.
