Title: The Innovative Contributions of Tsurumasa Matsushita
Introduction
Tsurumasa Matsushita, a distinguished inventor based in Funabashi, Japan, has made significant strides in the field of automation and control systems. With a total of two patents to his name, Matsushita's work focuses on enhancing programmable controllers and improving the performance of stepping motors.
Latest Patents
Matsushita's latest patents reflect his innovative spirit and technical expertise. The first patent is for a "Programming method and apparatus for programmable controller". This invention introduces a sequence program constructed through a ladder diagram on a display screen. The method involves arranging elements corresponding to the ladder diagram using both symbol and character elements. The inputting and amending operations of the ladder diagram are executed via two cursors—one for designating each element and the other for adjusting the character element associated with the first cursor's designation.
His second patent is a "Stepping motor control system", which addresses the challenges associated with the settling time of stepping motors. The innovation provides a method for reducing oscillation as the rotor approaches its target angular position, ultimately shortening the settling time. This is achieved by successively changing the phase excitation on each winding of the stepping motor and gradually adjusting the changeover as the rotor nears the target position, leading to a smoother performance.
