Title: Daizou Yamazaki: Innovator in Position Determination Technology

Introduction

Daizou Yamazaki is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of position determination technology, holding two patents that showcase his innovative approach to solving complex problems.

Latest Patents

Yamazaki's latest patents include a device for determining position coordinates of points on a surface. This device features a tablet with multiple equally spaced driver and sense windings. Each driver winding consists of parallel conductors arranged in the X-direction, while each sense winding has parallel conductors in the Y-direction. The device generates a current in a cursor coil through voltage induced from a nearby driver winding. This current induces a voltage in a nearby sense winding, allowing for the determination of the cursor's position on the tablet. Additionally, auxiliary sense windings are incorporated to enhance the accuracy and speed of position determination.

Another patent by Yamazaki also focuses on a device for determining position coordinates of points on a surface. This invention includes a cursor structure, a grid structure, and a signal processor. The cursor structure is equipped with a cursor coil and a signal generator that impresses a reference phase voltage to the coil. The induced voltages from the cursor coil in the grid structure's conductors are processed by the signal processor to produce a position-dependent phase voltage. Reference phase pulses are derived from a voltage induced in an auxiliary grid conductor, further improving the device's functionality.
