Title: Hisato Haraga: Innovator in Water Technology
Introduction
Hisato Haraga is a prominent inventor based in Chigasaki, Japan. He has made significant contributions to the field of water technology, holding a total of 13 patents. His innovative designs focus on improving water electrolyzers and toilet flushing devices, showcasing his commitment to enhancing efficiency and sustainability.
Latest Patents
One of Haraga's latest inventions is the membraneless water electrolyzer. This device is designed to electrolyze water to produce and recover acidic and/or alkaline water without the use of a membrane between the electrodes. The electrolyzer features a laminar-flow type design, where the anode and cathode are positioned closely together, allowing for a narrow flow path. This configuration minimizes turbulence during the separation of acidic water, ensuring that highly acidic water can be effectively recovered.
Another notable invention is the toilet bowl flushing device. This device controls the flow rate of flushing water supplied to a toilet bowl, optimizing the amount of water used for maximum flushing effect. It includes a water supply system, a flow rate control valve, an actuator, and a controller that manages the operation of the actuator. The controller adjusts the valve's opening stepwise during a flushing cycle, allowing for a variable flow rate that enhances the flushing process while conserving water.
