Title: Innovations of Tatsuo Bizen

Introduction

Tatsuo Bizen is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of electronics, particularly in the development of oscillation circuits. With a total of 6 patents to his name, Bizen continues to push the boundaries of innovation in his industry.

Latest Patents

One of Bizen's latest patents is a method of adjusting the variable range of oscillation frequency. This invention involves a resonance inductor formed of a chip inductor and an inductance fine adjustment pattern. A resonance capacitor is created using multiple chip layered capacitors connected in parallel, allowing for capacitance adjustments through sequential disconnection of connection patterns on a substrate. Additionally, the inductance fine adjustment pattern can be partially removed to fine-tune the inductance of the resonance inductor.

Another notable patent is for a voltage-controlled oscillation circuit with an impedance element. In this design, a parallel resonance circuit is established by connecting a coil and a capacitor in parallel. A control voltage is applied at the control terminal, which influences the resonance frequency of the circuit. The oscillation stage of the circuit then oscillates at this frequency, with the output being delivered through a buffer stage and an output matching stage.
