Latest Patents
One of Arai's latest inventions is an injection device that features a screw disposed in a heating cylinder, allowing for both rotational and axial movement. This device includes an injection stage that supports the heating cylinder, along with a material supplying unit that delivers resin material to the cylinder. A unique material introducing member is positioned between the supplying unit and the heating cylinder, facilitating the transfer of resin material. This member is designed with a cylindrical portion that fits into a vertical hole in the injection stage, ensuring efficient operation. Additionally, a heat medium passage runs through the sidewall of the cylindrical portion, allowing for temperature control, while a heat-insulating air space is created between the cylindrical portion and the vertical hole.
Another notable patent involves a method for producing a carbon nanocomposite metal material. This method enhances the dispersibility of carbon nanomaterials and improves the binding between the carbon nanomaterial and the matrix metal stock. The process involves mixing the matrix metal stock with microparticulate-coated carbon nanomaterial, compacting the mixture, and maintaining it at a temperature above the melting point of the matrix metal stock. This innovative approach leads to the production of high-quality metal articles molded from the carbon nanocomposite material.
