Title: Hiroshi Watanabe: Innovator in Ignition Technology
Introduction
Hiroshi Watanabe is a notable inventor based in Takahagi, Japan. He has made significant contributions to the field of ignition technology, holding a total of 6 patents. His work primarily focuses on improving the efficiency and performance of internal combustion engines.
Latest Patents
Watanabe's latest patents include an ignition apparatus designed for use in internal combustion engines. This innovative apparatus is received in a plug hole formed by a cylinder head and a cylinder head cover. It features a side core with a slit between two horizontally extending side wall ends, which is selected from a laminated sheet structure comprised of two grain-oriented silicon steel sheets. The alignment of the plural slits at substantially the same position prevents a one-turn short of a magnetic flux of the side core, allowing for a predetermined secondary voltage that exceeds the engine's requirement. Another notable patent is for an igniter for internal combustion engines, which aims to reduce the bulk and weight of the upper igniter case division. This igniter is designed to lower the center of gravity of the total apparatus, making it more stable against oscillation. The igniter unit incorporates a semiconductor device with a silicon chip that integrates a semiconductor for switching and current limiting circuitry.
