Title: Eiichi Uno: Innovator in Ignition Technology
Introduction
Eiichi Uno is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of ignition technology, holding 2 patents that showcase his innovative approach to enhancing engine performance.
Latest Patents
Uno's latest patents include an electronic ignition device for interval combustion engines. This current-interrupting type ignition device features an ignition coil with a primary winding, a secondary winding, and an auxiliary winding. The auxiliary winding is designed to have fewer turns than the primary winding and is energized in a manner that allows electromagnetic flux to flow in the opposite direction of the primary winding when activated. This arrangement enables current to flow through the auxiliary winding via a transistor and a diode when the primary current is interrupted, thereby enhancing the voltage induced across the secondary winding.
Another significant patent is the electromagnetic type contactless ignition apparatus for internal combustion engines. In this invention, the output signal induced in an electromagnetic pickup, which corresponds to the rotational speed of the engine, is applied to an input transistor. The output of this transistor is connected to a power transistor, which controls the current flowing in the primary winding of the ignition coil. A DC bias voltage is applied to the input of the input transistor, allowing for adjustments in its operating level, which in turn modifies the on and off periods of the power transistor.
