Title: Innovations by Tadashi Honkawa

Introduction

Tadashi Honkawa is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of analytical technology, holding a total of 4 patents. His work primarily focuses on methods and devices for analyzing various components in mixed solutions.

Latest Patents

One of his latest patents is a fluorescence polarization analyzer. This invention involves adding 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 filtering. To determine the fluorescence polarization during the filtering process, approximate equations are established based on the measured fluorescence polarization during the reaction. The reaction process is approximated using both linear and curve functions, enhancing the reliability of the resulting data.

Another significant patent is a method and device for analyzing a single ingredient in a mixed solution using two light beams of different wavelengths. This invention includes processes where a light beam from a source is divided into a fixed wavelength and a variable wavelength. The photometric signals resulting from the passage of these light beams through a solvent and a solution containing a coexisting ingredient are normalized and converted into absorbance signals. This method allows for the elimination of the influence of the coexisting ingredient, producing a difference-absorbance spectrum of the ingredient to be analyzed.
