Title: Innovations of Tadashi Itoh

Introduction

Tadashi Itoh is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of ink jet printing technology. With a total of 3 patents to his name, his work has advanced the capabilities of printing apparatuses.

Latest Patents

One of his latest patents is the "Deflection Control Ink Jet Printing Apparatus." This invention is capable of compensating for dislocation of dots at all deflection steps. It adjusts the deflection amount with respect to two points to determine a correlation between the amplification gain, charge code, and deflection amount. This ensures that an amplification gain and a charge code free from dislocation is set for each deflection step. Additionally, a charge code compensation value is detected and added to or subtracted from a predetermined charge code assigned to each deflection step, thereby setting a charge voltage code for the printout operation.

Another significant patent is the "Multicolor Ink Jet Recording Apparatus Having Means for Preventing." This apparatus allows an ink jet head to print an image by superposing individual dot matrices of at least two colors. A computing unit receives electrical input signals representing the image and generates corresponding electrical signals for the head means for printing. The computing means includes matrix generator means that limit the total number of dots to be printed in all matrices to a first predetermined value, ensuring efficient printing.
