Title: Yui Matsumoto and Her Water-Treatment Inventions.
Introduction
Yui Matsumoto is an inventor based in Aichi, Japan, whose work focuses on water-softening and water-treatment technologies. Her listed inventions address water softening, pH neutralization, and the regeneration of treatment materials. Matsumoto is associated with Panasonic Intellectual Property Management Co., Ltd. The provided information lists 2 patents.
Latest Patents
Matsumoto’s listed patent work includes a water-softening device and a water softener system.
The water-softening device uses weakly acidic cation-exchange resin to remove hardness components from raw water. It has two water-softening tanks and two neutralizing tanks, where weakly basic anion-exchange resin neutralizes the pH of softened water. The device directs water through the first softening tank, first neutralizing tank, second softening tank, and second neutralizing tank in sequence. The associated patent title also refers to recycling and cleaning methods for the device.
The water softener system combines a water-softening tank, a neutralization tank, an electrolysis tank, and a treatment tank. The electrolysis tank produces acidic and alkaline electrolyzed water to regenerate the cation- and anion-exchange resins, respectively. The treatment tank mixes the used acidic and alkaline electrolyzed water and returns the mixture to the electrolysis tank.
