Title: Innovations of Tatsuo Maeoka
Introduction
Tatsuo Maeoka is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of ignition apparatus and choke coils, holding a total of 5 patents. His work has been instrumental in improving the efficiency and performance of gasoline engines.
Latest Patents
One of Maeoka's latest patents is an ignition apparatus designed for gasoline engines of the independent cylinder type. This innovative device utilizes low-voltage wiring and eliminates the need for a distributor by employing a Capacitor Discharge Ignitor (CDI). This advancement enhances the ignition characteristics of lean mixtures. To extend the discharge time of the CDI-type ignition apparatus, the primary winding of a transformer is connected in parallel with a capacitor, which is linked to a DC power supply. The switching element in this design includes an Insulated Gate Bipolar Transistor (IGBT) and a diode connected in parallel.
Another significant patent is for a choke coil that features two coils wound over adjacent portions of a first magnetic core with two closed magnetic circuits and a second magnetic core. The winding directions of these coils are configured to cancel each other's magnetomotive forces in the second magnetic core. This design effectively reduces higher harmonics of the input current from the power source circuit while simultaneously functioning as a noise filter.
