Patent number: 9126773Abstract: The object of the present invention is to suction all powders and granular materials in a container such as a drum to transport them. The powders and granular materials have low flowability, since over time they have been compacted due to their own weight or vibrations from the outside or humidity. The machine (1) for suctioning powders and granular materials comprises movable tables (2, 3) that the container that stores the powders and granular materials is mounted on and that horizontally move, a device (8) for driving the tables, a double-layered suction nozzle (11) that is located above the tables and is connected to a suction source, a device (12) for moving the nozzle up and down in the container mounted on the tables, and a controller for controlling the devices, wherein, while moving the tables, the suction nozzle is inserted in proper positions in the container to suction the powders and granular materials.Type: GrantFiled: December 10, 2009Date of Patent: September 8, 2015Assignee: SINTOKOGIO, LTD.Inventors: Takehiko Hino, Harumitsu Asano, Hirofumi Asai

Patent number: 8710469Abstract: In an ion implantation method, ion implantation into a substrate is performed while changing a relative positional relation between an ion beam and the substrate. A first ion implantation process in which a uniform dose amount distribution is formed within the substrate and a second ion implantation process in which a non-uniform dose amount distribution is formed within the substrate are performed in a predetermined order. Moreover, a cross-sectional size of an ion beam irradiated on the substrate during the second ion implantation process is set smaller than a cross-sectional size of an ion beam irradiated on the substrate during the first ion implantation process.Type: GrantFiled: September 6, 2013Date of Patent: April 29, 2014Assignee: Nissin Ion Equipment Co., LtdInventors: Hirofumi Asai, Yoshikazu Hashino
