Title: Mitsunao Okumura: Innovator in Electronic Components

Introduction

Mitsunao Okumura is a prominent inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of electronic components, holding a total of 9 patents. His innovative designs have advanced technology in various applications, particularly in ignition coils and electronic components.

Latest Patents

One of Okumura's latest patents is for an ignition coil. This ignition coil features a primary coil that includes a distributed constant circuit with inductance and capacitance. A thyristor is connected in parallel to the primary coil, and a secondary coil is magnetically coupled to the primary coil. When a predetermined voltage is supplied to the primary coil, the capacitance is charged. If the thyristor is turned on, the capacitance discharges sequentially with time deviation, as the charge of the capacitance is delayed by the inductance connected in parallel.

Another notable patent is for an electronic component that includes a plurality of current path pairs arranged on the same circle. Currents flow through first current paths in one direction, while currents flow through second current paths in the opposite direction. This arrangement allows the magnetic fields generated by the currents to cancel each other out, reducing residual inductance. In cases where the electronic component is a cable, the current paths are conductors buried in an insulation member. If the component is a capacitor, at least one of the current paths forming the pair is a capacitor unit.
