Title: Noriaki Oyabu: Innovator in Microscope Measurement Technology
Introduction
Noriaki Oyabu is a distinguished inventor based in Kyoto, Japan. He has made significant contributions to the field of microscope measurement instruments, holding a total of 4 patents. His innovative approaches have enhanced the efficiency and accuracy of measurement techniques in scientific research.
Latest Patents
One of Oyabu's latest patents is a scan device for microscope measurement instruments. This invention involves a probe needle that is successively moved to multiple measurement points within a sample's measurement region. The device features an excitation control unit that feedback-controls a piezoelectric element to maintain a constant vibration amplitude of a cantilever based on the detection output from a displacement detection unit. Additionally, a vertical displacement control unit ensures a consistent distance between the probe needle and the sample, adapting to frequency shifts detected by a frequency detection unit. This innovative design allows for a more efficient measurement process, significantly reducing the time required to create convex/concave images compared to conventional techniques.
Another notable patent is a method for analyzing samples in liquid. This method effectively prevents the evaporation of the liquid being analyzed. By using a scanning probe microscope (SPM), a sealing liquid that is immiscible with the analysis liquid is filled around the sample, isolating it from external gases. This setup allows the SPM to scan the sample's surface and detect interactions, generating detailed images while maintaining the integrity of the liquid sample.
