Title: The Innovative Mind of Rikoku Nakamura

Introduction

Rikoku Nakamura, a prominent inventor based in Yamanashi, Japan, has made significant contributions to the field of sensor technology. With a total of eight patents to his name, Nakamura's work focuses on enhancing the functionality and efficiency of piezoelectric sensors and pressure detection devices. His innovations demonstrate a keen understanding of both electrical engineering and practical applications.

Latest Patents

One of Nakamura's latest patents involves a novel piezoelectric sensor. Traditional amplification factor adjustment methods, which often require cutting wiring patterns or using laser-trimmable resistors, are limited in effectiveness when the sensor is fully assembled. This complexity can lead to increased production costs and issues with amplification accuracy in finished products. To overcome these challenges, Nakamura has integrated a non-volatile memory into an integrated circuit that includes piezoelectric sensor circuit elements. This innovation allows for the amplification factor to be adjusted by writing data from a writing terminal, thus changing an amplification resistor without needing to modify the physical components after assembly.

Additionally, his invention of a disconnection detection circuit for pressure detection devices is noteworthy. This circuit employs a pull-up resistor for feeding detection signals and can connect a signal line to a power supply or a pull-down resistor connecting the signal line to ground (GND). The design also includes a voltage clip circuit with both high-voltage and low-voltage clipping capabilities, ensuring the signal line voltage remains within specified limits, thereby enhancing the reliability of pressure detection applications.
