The image shows an open book with technical drawings and Japanese text. The book's pages are yellowed and aged. The left page contains three black-and-white technical drawings of an object from different angles. The drawings are arranged vertically and show a rectangular object. The object appears to have a cylindrical component and angled surfaces. The right page contains a single black-and-white technical drawing of a cylindrical object. The cylindrical object has a circular top and bottom. There is Japanese text written vertically on the left page and horizontally on the right page. The text is black and appears to be handwritten. The background of the image is white.
