Patent number: 11428824Abstract: A scintillator module includes a substrate, a columnar scintillator crystal layer formed on the substrate, and a non-adhesive moisture-proof member having a given hardness and opposing a crystal growing side of the columnar scintillator crystal layer. The moisture-proof member ensures a void between the moisture-proof member and individual conic peak portions of columnar scintillator crystals forming the columnar scintillator crystal layer under vacuum sealing, and holds the columnar scintillator crystal layer in a moisture-proof state between a moisture-proof layer and the substrate.Type: GrantFiled: April 9, 2019Date of Patent: August 30, 2022Assignee: YMIT Co., Ltd.Inventors: Fumiaki Kunimoto, Satomi Onishi

Patent number: 8007680Abstract: The present invention has for its object to provide an electrolyte solution which can dramatically suppress the time degradation in performance of an electrochemical device, especially an electrochemical capacitor. The present invention relates to an electrolyte solution for electrochemical device which comprises an imidazolium salt (A) represented by the general formula (1) as a main component, wherein the content of the imidazolium salt (B) represented by the general formula (2) is not more than 15% by weight to the total weight of the imidazolium salt (A) and imidazolium salt (B); (in the formula, R1, R2 and R3 may be the same or different and each represents an alkyl group containing 1 to 3 carbon atoms; R4 and R5 may be the same or different and each represents an hydrogen atom or an alkyl group containing 1 to 3 carbon atoms; and X? represents a counter anion) (in the formula, R1, R3, R4, R5 and X? are the same as the definition for the general formula (1)).Type: GrantFiled: September 28, 2006Date of Patent: August 30, 2011Assignees: Sanyo Chemical Industries, Ltd., Panasonic CorporationInventors: Koji Fujioka, Yoshihiko Akazawa, Yasuyuki Ito, Satomi Onishi

Patent number: 7881043Abstract: A wound electric double-layer capacitor suppresses electrochemical reaction on polarized electrode layers, reduces characteristic degradation, and has high reliability. The capacitor has a capacitor element formed by winding positive and negative electrodes with a separator interposed between them, a metal case for storing the capacitor element and an electrolyte for driving, and a sealing member for sealing an opening of the metal case. In the positive and negative electrodes, positive and negative electrode lead wires are coupled to exposed parts of current collectors having polarized electrode layers on their both surfaces, respectively. The negative electrode is wound at least one extra turn from the winding end of the positive electrode of the capacitor element, and hence a part where the polarized electrode layers formed in the negative electrode face each other through the separator is formed on the outermost periphery of the capacitor element.Type: GrantFiled: November 21, 2006Date of Patent: February 1, 2011Assignee: Panasonic CorporationInventors: Eri Hirose, Yoshinori Takamuku, Yasuyuki Ito, Satomi Onishi

Patent number: 7706129Abstract: In an electric double-layer capacitor, resistance of a polarizable electrode layer is reduced and gas generation inside a case is suppressed in an attempt to improve reliability. On that account, an electric double-layer capacitor is provided, which is obtained by housing in a case, together with a driving electrolyte, a capacitor element wound with a separator interposed between electrodes being paired anode and cathode electrodes in each of which polarizable electrode layers are formed on and lead wires are fixed to both sides of a current collector made of metallic foil, such that the polarizable electrode layers are opposed to each other. Further, an electric double-layer capacitor is provided in which the lead wire is fixed to a polarizable-electrode-layer-removed section on the electrode where the polarizable electrode layer has been removed, and an area of the polarizable-electrode-layer-removed section is not smaller than 1 and not larger than 2.Type: GrantFiled: May 25, 2007Date of Patent: April 27, 2010Assignee: Panasonic CorporationInventors: Eri Hirose, Yasuyuki Ito, Satomi Onishi, Mitsuru Iwai, Takumi Yamaguchi, Ichiro Aoki, Kouji Moriyama, Yoshiki Hashimoto
