Latest Patents
One of Araki's latest patents is for an ink jet printer and ink jet printing method. This invention features a pressure generation chamber that expands in a stepped manner, allowing for high-speed discharge of very small ink droplets. Prior to ink discharge, the pressure generation chamber contracts to enable high-accuracy gradation printing with a wide range of ink droplet sizes. The control unit generates various signals to manage the contraction and expansion of the pressure generation chamber, ensuring precise ink discharge and retraction.
Another notable patent is a method and apparatus for manufacturing multilayer printed circuit boards. This innovation allows for the accurate lamination of printed circuit boards with precise positional alignment. The system includes supporting means for both the first and second printed circuit boards, along with movement mechanisms that enable free sliding movement in the X-direction. The positions of respective marks on the printed circuit boards are imaged, and any positional errors are corrected through image processing before securing the boards together.
