Patent number: 12259340Abstract: A nondestructive inspecting device (10) includes a neutron emission device (2) that emits a neutron beam to a local irradiation location on a surface (la) of an inspection target (1), a detection device (3) that detects, at each of inspection positions facing the surface (la), scattered neutrons returned from the inspection target (1) as a result of emission of the neutron beam to the irradiation location, and measures the detected number of the scattered neutrons at each of the detection positions, and a ratio calculation unit (5) that calculates, for each of the detection positions, a ratio of the detected number at the detection position to a reference value for the detection position, and outputs the ratios. The reference value is set as the detected number at each of the detection positions in an assumed case of no defects existing in the inspection target (1).Type: GrantFiled: October 15, 2021Date of Patent: March 25, 2025Assignee: RIKENInventors: Kunihiro Fujita, Chihiro Iwamoto, Takaoki Takanashi, Yoshie Otake

Publication number: 20250027890Abstract: An observation device includes a neutron emission device, a detection device, and a data processing device. The neutron emission device emits neutrons to an inspection object. The detection device detects exit neutrons from the inspection object at one set of detection positions in a peripheral direction around the inspection object, outside the inspection object, and measures the number of the detected exit neutrons for each of the detection positions. The data processing device generates reconstructed cross-sectional data by performing reconstruction processing based on the number of the detected exit neutrons at each of the one set of detection positions. The reconstructed cross-sectional data represent a two-dimensional distribution of a neutron reaction rate in an imaginary cross-section of the inspection object.Type: ApplicationFiled: October 25, 2022Publication date: January 23, 2025Applicant: RIKENInventors: Kunihiro FUJITA, Takaoki TAKANASHI, Chihiro IWAMOTO, Yoshie OTAKE

Patent number: 9819017Abstract: There is provided a sealed battery having excellent corrosion resistance and sealing performance. The sealed battery 1 includes a battery jacket can 2 having a bottom and being in a cylindrical or polyhedral shape. The battery jacket can 2 also serves as a collector of one of the electrodes. The battery jacket can 2 has an opening pointing upwards and accommodates active parts (3, 4, 5 and 20). The opening is sealed by a sealing part 10 that includes a flat metal sealing plate 6, a gasket 9 made of an insulator, and a terminal part 7 of the other electrode. In the sealing part, the terminal part is attached to the sealing plate 6 using the gasket 9. The sealing plate has a planar shape that matches a shape of the opening of the battery jacket can. The sealing plate is in a saucer shape whose edge section is bent upwards.Type: GrantFiled: August 5, 2015Date of Patent: November 14, 2017Assignee: FDK CorporationInventors: Satoshi Sunada, Takahide Kobashi, Yoshie Fujita, Nobuhiro Nishiguchi

Patent number: 9484585Abstract: There is provided non-aqueous organic electrolytic solution for a lithium primary battery which can be stored for long period at elevated temperatures or at the end stage of discharge. Non-aqueous organic electrolytic solution 20 for lithium primary battery 1 having a cathode active material which is manganese dioxide and an anode active material which is either of lithium or lithium alloy includes a base electrolytic solution that is composed of organic solvent and supporting electrolyte and to which either one of hydroxyphthalimide or hydroxyphthalimide derivative is added as an additive. An amount of the additive which is added to the base electrolytic solution is 0.1 wt % or more and 5.0 wt % or less. It is more preferable that the amount of the additive which is added to the base electrolytic solution is 0.1 wt % or more and 1.0 wt % or less.Type: GrantFiled: February 4, 2015Date of Patent: November 1, 2016Assignees: FDK Corporation, FDK Tottori Co., Ltd.Inventors: Yoshie Fujita, Satoru Naruse, Satoshi Sunada, Naoaki Nishimura, Takahide Kobashi
