Title: Keita Morikawa: Innovator in Hydraulic Systems
Introduction
Keita Morikawa is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of hydraulic systems, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
Morikawa's latest patents include a spool valve device and a hydraulic pump operating device. The spool valve device features a housing with channels and a spool that moves to change channel connection statuses. It incorporates an electric actuator that includes an electric motor and a linear-motion conversion mechanism. This mechanism converts the rotational movement of the output shaft into straight movement, applying thrust to the spool. Additionally, it has a biasing member that applies force against the actuator thrust and an angle detector that monitors the motor's output shaft position. The device also includes a driving portion that controls the motor based on position commands and an abnormality determining portion that detects any operational anomalies.
His second patent, the hydraulic pump operating device, involves setting the rotational frequency of a variable speed motor to a normal value. It detects pressure variation ranges and determines if the pressure is maintained over a specified period. If the pressure remains stable, the motor's frequency is adjusted accordingly to maintain optimal performance.
