Latest Patents

One of Shuji Ito's latest patents is a vibration damping material designed to exhibit excellent vibration damping properties over a wide temperature range. This invention involves a magnetic composite type damping material, which is constructed by bonding an adhesive elastic sheet containing magnetic powder to a constraining plate, such as a metal plate, using an adhesive. The adhesive elastic sheet is made from a composite material that includes rubber elastomer, adhesive resin, plasticizer, and magnetic powder. This unique construction allows the damping material to be attracted by magnetic force against a vibration source while also providing superficial adhesiveness. The synergistic effect of the magnetic force and adhering force results in outstanding vibration damping properties across a broad temperature range.

Another significant patent by Shuji Ito is a rubber-coated gasket material. This material features a rubber layer formed on one or both sides of a metal sheet. The rubber layer incorporates nitrile rubber containing a carboxyl group, with the proportion of a carboxylic monomer calculated in terms of monomer content in the rubber component ranging from 2-15 wt.%. The rubber layer is applied in a thickness of 10-300 µm per side and is bonded to the metal sheet with a primer layer based on phenolic resin interposed between the rubber layer and the metal sheet.
