Title: Naotsugu Seko: Innovator in Flow Measurement and Control

Introduction

Naotsugu Seko is a prominent inventor based in Nagoya, Japan. He has made significant contributions to the field of flow measurement and control, holding a total of 4 patents. His innovative designs have advanced the technology used in various industrial applications.

Latest Patents

One of Seko's latest patents is a flowmeter that includes a sensor passage equipped with a sensor chip for measuring flow rates. This flowmeter features an orifice passage as a bypass, which is strategically placed in relation to the sensor passage. The orifice passage has a smaller diameter than the inflow passage, and a distribution orifice is positioned on the inlet side of the sensor passage. This configuration ensures that the changing trends in the effective sectional area are consistent in a graph that plots effective sectional area against fluid pressure.

Another notable invention is a flow control valve designed to prevent adhesion between a fixed core and a movable core. This valve enhances the attractive force, allowing for high-accuracy flow control. In this design, a first fixed core is secured in the upper part of a coil bobbin, while a second fixed core is fixed in the lower part. The movable core is designed with a flange at its lower end, which has a diameter larger than the inner diameter of the coil bobbin. This innovative arrangement allows for improved functionality in flow control applications.
