Title: Innovations of Yoshio Maeda
Introduction
Yoshio Maeda is a prominent inventor based in Katsuta, Japan. He has made significant contributions to the field of technology, holding a total of 7 patents. His work primarily focuses on advancements in fluorescence analysis and wavelength measurement.
Latest Patents
One of his latest patents is a fluorescence polarization analyzer. This innovative device adds a fluorescent dye to a sample containing lymphatic cells stimulated by antibodies to measure fluorescence polarization. The polarization varies over time, and the measurement is halted after a predetermined duration. The lymphatic cells are then separated from the sample through a filtering process. To determine the fluorescence polarization during this filtering, approximate equations are derived based on the measured polarization during the reaction. The reaction process is modeled using both linear and curve approximations, enhancing the reliability of the resulting data.
Another notable patent is a wavelength reading apparatus for a monochromator. This apparatus includes a monochromator that utilizes a dispersion element to disperse light according to its wavelengths. It features a driver unit that rotates the dispersion element for tuning wavelength scanning and a wavelength counter that tracks changes in wavelength. The counter is calibrated to ensure accurate representation of the monochromator's tuning wavelength.
