Publication number: 20230078595Abstract: An automatic analyzer has a supply unit that stores and supplies a liquid to be used by the analyzer, an analyzer circulation system that circulates the liquid within the analyzer, and a supply unit circulation system that circulates the liquid within the supply unit. An analysis controller switches a flow rate of the liquid circulated by at least one of the analyzer circulation system and the supply unit circulation system between a first flow rate in a normal state and a second flow rate different from the first flow rate. Consequently, by suppressing fungal propagation within a circulation flow path for a liquid, compared to conventional techniques, the frequency with which a liquid is replaced and the frequency with which the inside of a reaction tank is cleaned are reduced and a time period for a maintenance operation by an operator is reduced.Type: ApplicationFiled: February 5, 2021Publication date: March 16, 2023Inventors: Kumiko KANAI, Yoko INOUE, Shotaro SAGAWA, Yusuke MINEMURA, Yoichiro SUZUKI

Patent number: 8852799Abstract: An object of the invention is to provide an inexpensive non-aqueous electrolyte secondary battery that allows reversible charge and discharge to be carried out and can be used for a long period because of a stable non-aqueous electrolyte used therein. The invention provides a non-aqueous electrolyte secondary battery including a positive electrode including a positive electrode active material and capable of storing and releasing sodium, a negative electrode capable of storing and releasing sodium, and a non-aqueous electrolyte, and the positive electrode active material includes sodium, nickel, manganese, and a transition metal that can exist in a hexavalent state. An example of the transition metal that can exist in a hexavalent state may include tungsten (W). An example of the negative electrode may include a sodium metal capable of storing and releasing sodium ions.Type: GrantFiled: September 4, 2006Date of Patent: October 7, 2014Assignee: C/O Intellectual Property H.Q., Sanyo Electric Co., Ltd.Inventors: Masaharu Itaya, Hideyuki Koga, Kumiko Kanai, Takao Inoue, Masahisa Fujimoto

Patent number: 8815449Abstract: A material (hereinafter referred to as “positive electrode material”) including sodium manganate powder as a positive electrode active material, carbon black powder as a conductive agent, and polytetrafluoroethylene as a binder is prepared. The positive electrode material is mixed in an N-methylpyrrolidone solution to produce slurry as a positive electrode mixture. A working electrode is produced by applying the slurry on a positive electrode collector. A negative electrode containing tin or germanium is produced. The non-aqueous electrolyte is produced by adding sodium hexafluorophosphate as an electrolyte salt in a non-aqueous solvent produced by mixing ethylenecarbonate and diethyl carbonate.Type: GrantFiled: January 20, 2006Date of Patent: August 26, 2014Assignee: Sanyo Electric Co., Ltd.Inventors: Takao Inoue, Masahisa Fujimoto, Kumiko Kanai

Publication number: 20100015532Abstract: A rolled foil of surface roughened copper as thick as 26 ?m for example having a surface formed into an irregular shape with copper precipitated thereon by an electrolytic method is prepared as a negative electrode collector. Tin (Sn) or germanium (Ge) is deposited on the rolled foil described above, so that a negative electrode active material layer is formed. Note that the deposited tin or germanium is amorphous. The arithmetic mean roughness Ra in the surface-roughened rolled foil described above is preferably not less than 0.1 ?m nor more than 10 ?m. A non-aqueous electrolyte is produced by adding sodium hexafluorophosphate as an electrolyte salt in a concentration of 1 mol/l to a non-aqueous solvent produced by mixing ethylene carbonate and diethyl carbonate in the ratio of 50:50 by volume.Type: ApplicationFiled: January 20, 2006Publication date: January 21, 2010Inventors: Takao Inoue, Kumiko Kanai, Masaharu Itaya, Masahisa Fujimoto
