Title: The Innovations of Takeshi Hanai
Introduction
Takeshi Hanai is a notable inventor based in Kuwana, Japan. He has made significant contributions to the field of spark plug manufacturing, holding a total of 4 patents. His work focuses on improving the efficiency and accuracy of spark plug components.
Latest Patents
One of his latest patents is a manufacturing method for a spark plug. This method involves a bonding step where one end of the ground electrode is attached to a metallic housing. Following this, a provisional bending step is performed, bending the intermediate portion of the ground electrode to ensure that the other end is aligned with the center electrode's distal end surface. A regular bending step is then executed to adjust the spark gap dimension. Additionally, receiving dies are utilized to regulate the position of the ground electrode during the bending process.
Another significant patent is an adjusting method for centering the earth electrode at the center electrode of the spark gap. This invention aims to efficiently adjust the positional difference between the center electrode axis and the center of the earth electrode. By illuminating the tips of both electrodes and processing their images, the positional difference can be accurately calculated and adjusted using a motorized jig.
