Latest Patents
Kinoshita holds a patent for a "Device for sealing a propeller shaft against invasion of sea water." This sealing device is designed to be installed around a ship's propeller shaft. It features longitudinally spaced annular iron pole blocks and circularly spaced permanent magnets fixed between the blocks. These components are housed in a cylindrical casing that surrounds the propeller shaft. A magnetic fluid fills the gaps between the magnets and the annular iron pole blocks, or the shaft itself. This magnetic fluid acts as a sealant, completing a magnetic circuit that maintains a defined thickness of the sealant. It ensures a high-pressure seal even under significant mechanical stress, thereby minimizing frictional power loss and wear on the propeller shaft.
