Latest Patents

One of Maeda's latest patents is an "Apparatus and method for multistage reverse osmosis separation." This invention relates to an apparatus and method that comprises reverse osmosis membrane module units arranged in multiple stages, with a booster pump provided in the concentrate flow channel between the units. The total effective reverse osmosis membrane area of a module unit is designed to be between 20-80% of that of the preceding module unit. The objective of this invention is to produce low-concentration solutions from high-concentration solutions with a high recovery ratio, minimal energy requirements, and enhanced stability.

Another significant patent is the "Vertical carbonizing furnace for use in the production of carbon fibers." This invention features a vertically extending conduit of hollow rectangular parallelepiped shape. The lower end of the conduit is immersed in water, creating a water seal from environmental air. Additionally, the conduit includes a gas withdrawal outlet that communicates with the upper portion through a gas feeding duct for reuse. This design allows for the withdrawal of a mixture of vapor evaporated from the water seal and an inert gas, which is then fed back to the upper portion of the conduit to prevent deterioration of fibers and the conduit itself.
