Title: Fujio Tamura: Innovator in Vacuum Gauge Technology

Introduction

Fujio Tamura is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of vacuum gauge technology, holding three patents to his name. His work focuses on innovative solutions for measuring pressure in various environments.

Latest Patents

One of his latest patents is a Quartz Vacuum Gauge. This device measures the pressure of environmental gas using a quartz resonator that oscillates at a frequency dependent on its body temperature. The resonator's temperature is influenced by relatively low pressure, while a heat source maintains its body temperature, producing an output signal that represents the pressure in low-pressure ranges. Additionally, a converter transforms the resonant current into a second output signal for high-pressure ranges, which is displayed on a meter.

Another significant patent is the Vacuum Gauge of Thermo-Conductive Type with Quartz Oscillator. This gauge measures gas pressure within a chamber using a quartz oscillator that oscillates at a frequency based on its body temperature. A constant heat source is positioned to maintain the oscillator's temperature, which is dependent on the surrounding gas pressure. The oscillating frequency is then converted into a signal that indicates the gas pressure.
