Title: Innovations of Atsuko Tsuchida
Introduction
Atsuko Tsuchida is a prominent inventor based in Saitama, Japan. She has made significant contributions to the field of humidity measurement technology. With a total of 6 patents to her name, her work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of her latest inventions is a humidity meter that features an oscillator circuit. This circuit includes a C-MOS type gate that increases the operating current with rising operating frequency. The humidity sensor within the circuit changes its electric impedance according to humidity levels. This oscillator circuit effectively converts changes in humidity into frequency variations, which are then transformed into changes in operating current for output. Additionally, to enhance the response of the operating current to frequency changes, a series circuit with a capacitor and resistor is connected as a capacitive load.
Another notable invention is an absolute humidity meter. This device utilizes a humidity sensor that alters its electrical impedance exponentially in relation to relative humidity. A z-f converting circuit generates a pulse signal corresponding to this impedance. The time constant control differentiating circuit outputs a differentiated signal by processing the pulse signal. The waveform shaping circuit then produces a binary-valued pulse signal train. Two integrating circuits are employed to derive control voltage and output voltage for relative humidity signals, ultimately providing an absolute humidity signal that adjusts with temperature changes.
