Latest Patents
Among Hisao Tokoro's latest innovations is the "Luneberg dielectric lens and method of producing same." This invention involves a unique hemispherical Luneberg dielectric lens composed of a central layer with a hemispherical outer surface and several concentric dome-shaped layers. Each layer is designed with varying diameters to create an integrated hemispherical shape. Notably, the center layer is made from a foam molding of ceramic-containing thermoplastic resin-expanded beads, while the dome-shaped layers comprise a thermoplastic resin that can contain up to 80% by weight of ceramic. This design ensures that the ceramic content decreases from the center to the outermost layer, with a standard deviation of apparent density maintained at 0.07 g/cm3 or lower. Additionally, he has invented a process for producing foamed molding from expanded polypropylene resin beads, which involves heating the beads in a mold to fuse them into a unitary body, utilizing surface-modified organic peroxides.
