Introduction

Masato Hanai is a notable inventor based in Atsumi-gun, Japan. He has made significant contributions to the field of engineering, particularly in the development of engine starter systems. With a total of 4 patents to his name, Hanai's work reflects a commitment to innovation and efficiency in automotive technology.

Latest Patents

One of Hanai's latest patents is an engine starter system featuring a duty-controlled switching device. This system includes a current switching device that manages the armature current, a shorting relay for electrically shorting the current switching device, and an electronic control circuit. In normal starting mode, the electronic control circuit gradually increases the armature current by adjusting the duty ratio of the current switching device. When the armature current exceeds the allowable current value, the armature is energized through the shorting relay. In the economy-running starting mode, the armature current is controlled until the engine is fully started.

Another significant patent is an engine starting method designed for idling stop conditions. This method involves a preliminary step where a pinion is pushed to engage with a ring gear when the vehicle is in an idling stop condition. Upon receiving an engine start signal, the starting step rotates the pinion into mesh with the ring gear, allowing the engine to start. After the engine starts, a restoring step resets the pinion to its original position. This innovative approach enhances the efficiency of engine startups in various operating conditions.
