Title: Innovations of Takeshi Sawada

Introduction

Takeshi Sawada is a notable inventor based in Kasugai, Japan. He has made significant contributions to the field of technology, particularly in signal processing and radiography. With a total of two patents to his name, his work reflects a commitment to advancing innovation.

Latest Patents

One of Sawada's latest patents is a nonlinear compensator. This device comprises a signal processing section, a distortion detecting section, and a distortion correcting section. The signal processing section detects the time difference and phase difference between two signals by calculating correlation, synchronizes the two signals, and aligns the phase of one signal with the other. The distortion detecting section identifies amplitude and phase errors in the signals, which are then input as distortion components to the distortion correcting section. This section sequentially selects the appropriate compensation amounts and adds them to the digital baseband signal to correct for distortion.

Another significant patent is the speed compensated intensifying screen for radiography. This invention features a layer of phosphor and a protective layer on a substrate, along with a light-absorbing layer that absorbs part of the light emitted from the phosphor layer. This design creates multiple regions with varying speeds within the phosphor layer, allowing for continuous changes in density across the borders. This innovation prevents visible line patterns in X-ray radiographs and ensures proper speed correction for various internal organs during imaging.
