Patent number: 6677547Abstract: A method and an apparatus for classifying and recovering the main components of used batteries, particularly, a method and an apparatus by which the batteries are conveyed on a conveyor while an alternating magnetic field of a plurality of frequencies is applied to each and a detection means detects what sort of induced magnetic field has resulted from the eddy current induced in the battery. The orthogonal components in the change of the induced magnetic field are detected; the relationship between these orthogonal components and the frequencies are compared with the database of the same which is previously obtained, and the batteries are sorted according to their classification and size. This method can sort large amounts of used batteries continuously. In this invention, the battery will be drawn down into the detection region either magnetically or mechanically while the stable transport of the battery is achieved.Type: GrantFiled: November 9, 2001Date of Patent: January 13, 2004Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Tadaaki Tanii, Satoshi Tsuzuki, Shiro Honnmura, Takeo Kamimura, Takahiko Hirai, Masaaki Kurokawa, Reizou Miyauchi

Patent number: 6524737Abstract: This invention provides a safe and efficient method of dismantling used lithium ion batteries. More specifically, the plastic cases which protect sealed battery cells are removed from the system in a stable and reliable fashion. Valuable materials such as lithium cobalt oxide, an oxide of a lithium-transition metal compound, aluminum and copper must be separated and recovered. The invention is distinguished by the fact that it entails the following processes. In the crushing process, the batteries are chilled to a temperature of −50° C. or lower. In this state they are repeatedly subjected to vibration and pressure by a number of objects whose rigidity and specific gravity are greater than those of the plastic. In this way the batteries are separated into sealed battery cells and plastic cases. In the heating process, the sealed battery cells separated in the process are heated to a temperature of at least 200° C. in a non-oxidizing atmosphere to separate mainly the organic materials.Type: GrantFiled: July 25, 2000Date of Patent: February 25, 2003Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Tadaaki Tanii, Satoshi Tsuzuki, Shiro Honmura, Takeo Kamimura, Kenji Sasaki, Masakazu Yabuki, Kiyonori Nishida

Patent number: 5680784Abstract: A method of controlling a form of a strip in a rolling mill. A plurality of paired data of manipulation amounts of form control actuators, and amounts of variations in the form of the strip corresponding to the manipulation amounts are prepared, as prototype manipulation examples. Calculation is performed to obtain a degree of similarity between an actual form error representing difference between an actual form of the strip and a target form, and variations in the form of the prototype manipulation examples. Then, actuator manipulation amounts of the prototype manipulation examples are weighted in accordance with calculated degree of the similarity, and the actuators are manipulated based on weighted actuator manipulation amounts.Type: GrantFiled: March 9, 1995Date of Patent: October 28, 1997Assignee: Kawasaki Steel CorporationInventors: Junichi Tateno, Kazuya Asano, Takayuki Kaji, Masashi Hoshino, Satoshi Tsuzuki, Motoji Shiozumi, Akinobu Kamimaru, Chikara Osaka
