Latest Patents

Among his latest patents is a scan device for a microscope measurement instrument. This invention features a probe needle that is progressively moved to various measurement points within a designated region on a sample, allowing for precise measurement of the z-displacement amount. A unique excitation control unit ensures that the vibration amplitude of a cantilever remains constant, adapting based on feedback from a displacement detection unit. Additionally, a vertical displacement control unit maintains a consistent distance between the probe needle and the sample by utilizing frequency shifts detected by a frequency detection unit. By optimizing the measurement timing, this invention significantly reduces unnecessary measurement duration, leading to improved throughput when creating convex/concave images compared to traditional techniques.

Another of Kobayashi's notable patents is the apparatus and method of obtaining a magnetic force field through measurement. In this approach, a magnetic force image is captured above a sample with magnetic domains. By processing both the magnetic force image and an auxiliary magnetic force image, the difference is divided by the distance to generate a magnetic force gradient image. Fourier transformation of both images permits the extraction of a three-dimensional field that accurately depicts the magnetic force, enhancing the understanding of the magnetic domains present at the sample's surface.
