Title: Iwao Ito: Innovator in Opening/Closing Devices
Introduction
Iwao Ito is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of engineering, particularly in the development of innovative opening and closing devices. With a total of 2 patents to his name, Ito's work has had a meaningful impact on sewage management systems.
Latest Patents
Iwao Ito's latest patents include advanced designs for opening and closing devices. The first patent describes an opening/closing device that features a gate designed to receive a flow of sewage in an upright state. This gate can fall toward the downstream side of the flow, and it is supported by a first spring that generates a force to return the gate to its upright position. Notably, this spring generates insufficient force to bring the gate upright if it is already in a fallen state, but it can do so if the gate is tilted at a predetermined angle.
The second patent also focuses on an opening/closing device, which includes a gate that receives sewage flow and can fall downstream. This design incorporates a fall prevention unit that supports the gate, a support release unit that activates when the first float surfaces, and a second float that is positioned above the first float. This innovative mechanism ensures that the gate operates effectively under various conditions.
