Title: Hiroshi Kagohashi: Innovator in Flow Control and Vacuum Pressure Systems
Introduction
Hiroshi Kagohashi is a notable inventor based in Kasugai, Japan. He has made significant contributions to the fields of flow control and vacuum pressure systems, holding a total of six patents. His innovative designs have advanced the technology used in various industrial applications.
Latest Patents
One of Kagohashi's latest patents is a flow control valve. This valve regulates flow rates by determining the stop position of a piston through contact in an opened state. It allows for remote and high-precision flow rate regulation. In a closed state, a return spring's urging force acts on the piston, bringing a diaphragm into close contact with a valve seat. When compressed air is supplied into a pilot chamber, the piston moves, and the diaphragm is brought out of contact with the valve seat, establishing an opened state. The position at which the piston contacts the nut can be adjusted using a servo motor, allowing for flexibility in operation.
Another significant patent is a vacuum pressure control system. This system measures the vacuum pressure in a reaction chamber using vacuum pressure sensors. The measured value can be adjusted at a set vacuum pressure changing speed, either commanded from the exterior or predetermined in the system's controller. The feedback control is executed as follow-up control, enabling uniform changes to the vacuum pressure in the reaction chamber at the desired speed.
