Patent number: 8439998Abstract: In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders (10) are used as metal powder materials. In addition, spherical particulate metal powders 11 are used as main materials, and random amorphous flaky metal fine powders 10 having finer particle size than the metal powders 11 and produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials (10) in the main materials (11). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.Type: GrantFiled: December 2, 2005Date of Patent: May 14, 2013Assignees: Sunrex Kogyo Co., Ltd., Nanopulus Co., Ltd., Ace Giken Co., Ltd.Inventors: Kenzo Ito, Masahiro Yamamoto, Etsuo Yamamoto

Patent number: 8398007Abstract: A jet mill in which crushed material introduced into a crushing chamber is comminuted by gas being sprayed from a plurality of gas-jet nozzles, wherein high-efficiency pulverization is performed by optimizing various pulverization conditions according to the type of crushed material or other such properties. The direction in which gas is sprayed into the crushing chamber is variable adjustable; the spraying direction of each nozzle is displaced simultaneously by the electromotive actuator; swirl flow is produced in three dimensions, including the flow of a directional component that is perpendicular to the horizontal swirl flow; and a fine-powder discharge port of a first pulverization chamber and a fine powder introduction port of a second pulverization chamber are communicatingly connected by a ventilation duct.Type: GrantFiled: October 18, 2011Date of Patent: March 19, 2013Assignees: Sunrex Kogyo Co., Ltd., Nanoplus Co., Ltd., Ace Giken Co., Ltd.Inventors: Kenzo Ito, Masahiro Yamamoto, Etsuo Yamamoto
