Introduction

Shintaro Gomi is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of electronics, holding a total of 6 patents. His work primarily focuses on advancements in amplifier technology and mobile antenna systems.

Latest Patents

One of Gomi's latest patents is a differential amplifier. This innovative device comprises first and second transistors whose emitters are connected through a resistance element. A third transistor receives a current equal to the collector current of the first transistor, while a fourth transistor receives a current equal to the collector current of the second transistor. The signals from the emitters of the third and fourth transistors are level-shifted and supplied to the bases of the first and second transistors, respectively. This design results in a differential amplifier that is linear in transfer characteristic and has a large input dynamic range.

Another significant patent is for a mobile antenna unit designed for use in the FM broadcast band. This antenna is adapted to be mounted on the windshield of a vehicle, providing a gain and directivity pattern similar to that of an external whip antenna. The antenna element is a conductor mounted near one of the pillars supporting the windshield. The pillar acts as an inductor, while the conductor functions as a capacitor. By properly dimensioning and spacing the conductor relative to the pillar, resonance is achieved in the FM broadcast band.
