Patent number: 7373570Abstract: A scan separator in a large scale integration device is made more extensive to suppress an increase in the circuit scale of the entire device. In one embodiment, a scan separator is provided for every two signal lines interconnecting two combinatorial circuit blocks. Each scan separator includes a selector and a flip flop for constituting a scan path. Another selector is provided for selecting one of the two signal lines. As an input selector signal for the selector that selects one of the two signal lines, data for switching controlling are used, which are transferred from a test input terminal over the scan path and latched by the flip flop. The data for switching controlling are initially transferred over the scan path to each flip flop. The selector that selects one of the two signal lines is switched in accordance with the switching controlling data stored in the flip flop. The switching controlling data may be interchanged to select the either of the two signal lines.Type: GrantFiled: December 19, 2005Date of Patent: May 13, 2008Assignee: Oki Electric Industry Co., Ltd.Inventors: Hiroyuki Hanamori, Kenji Asai, Hiroshi Yamasaki, Osamu Endoh

Publication number: 20080050295Abstract: A method of recovering valuable materials from lithium batteries wherein a lithium/transition metal composite oxide is used as a positive electrode active material. In this disposal method, a sheeted positive electrode having a positive electrode active material disposed on a positive electrode collector is immersed in an oxalic acid solution. By virtue of this oxalic acid treatment (step 240), any lithium element contained in the positive electrode active material can be leached into the oxalic acid solution. Using oxygen gas produced by a reaction between the positive electrode active material and oxalic acid, attachments, such as the positive electrode active material, can be self-detached from the positive electrode collector. The transition metal element contained in the positive electrode active material is converted by the oxalic acid treatment to insoluble transition metal compounds (oxalate, oxide, etc.).Type: ApplicationFiled: June 14, 2005Publication date: February 28, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoshimasa Uchida, Yoshimi Hirata, Kazutaka Arimura, Hiroshi Yamasaki
