Title: Yasuhito Maeshima: Innovator in Focus Voltage Control and Antenna Technology

Introduction

Yasuhito Maeshima is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of technology, particularly in focus voltage control apparatuses and antenna arrangements. With a total of 5 patents to his name, Maeshima continues to push the boundaries of innovation.

Latest Patents

One of Maeshima's latest inventions is a focus voltage control apparatus designed for color CRTs. This apparatus is capable of achieving a precisely focused state for any desired color, even during monochromatic displays. The device integrates red, green, and blue color signals per horizontal line period in integrating and peak holding circuits. These signals are then weighted in weight control circuits. A comparator detects the maximum color signal, which leads to the output of a corresponding color selection signal. This signal is then supplied to focus voltage converters, ensuring that the maximum color signal is displayed in a just-focused state.

Another significant patent is an innovative antenna and mounting arrangement. This design features a mounting portion that can be attached to the rear of a dish portion of the antenna. The mounting portion can be affixed to a pole and positioned at any point along its length. This flexibility allows for multiple antennas to be conveniently mounted on a single pole without any contact between the dish portion and the pole.
