Title: Toshihide Fujiwara: Innovator in Electrophoresis Technology

Introduction

Toshihide Fujiwara is a prominent inventor based in Fuchu, Japan. He has made significant contributions to the field of electrophoresis, holding a total of 12 patents. His work focuses on improving the processes involved in fractionating electrophoretogram signals, which has important applications in various scientific and medical fields.

Latest Patents

One of his latest patents is a process for fractionating electrophoretogram signals. This innovative process differentiates signals representing the electrophoretogram to obtain the first-order differential and generates a series of pulses that represent changes in sign. It further differentiates the first-order differential to obtain the second-order differential, generating another series of pulses. The output pulses are then logically processed to fractionate the electrophoretogram based on the timing of these pulses. Another notable patent is a fractionating method in electrophoresis, which allows for the automatic and accurate fractionation of patterns obtained from electrophoresis. This method aligns peak tops or minimum points of a sample with those of a normal sample, ensuring precise boundary point determination.
