Patent number: 11946847Abstract: An extracellular potential measurement device includes multiple insulating films each of which is made from an electric insulating material, the insulating films being stacked and bonded to each other; and multiple electrode wires each of which is made from an electroconductive material, the electrode wires being arranged in multiple heights. Each of the electrode wires is interposed between an upper insulating film and a lower insulating film. Each of the insulating films, except for a lowermost insulating film, has an opening penetrating the insulating film. The opening in a lower insulating film has a size that is less than that of the opening in an upper insulating film, the openings in the insulating films being overlapped to form a recess having a size reducing downward, the recess being adapted to store a collection of cells. Each of the electrode wires has an end that is located near an opening in an insulating film that is immediately below the electrode wire, the ends being exposed in the recess.Type: GrantFiled: October 1, 2020Date of Patent: April 2, 2024Assignees: NOK CORPORATION, THE UNIVERSITY OF TOKYOInventors: Takayuki Komori, Keiichi Miyajima, SooHyeon Kim, Teruo Fujii, Shinji Okawa

Patent number: 11551157Abstract: The reservation management system includes an input device and a reservation management unit. The input device includes a manual operation part movable between a first position and a second position and sends a wireless signal containing movement information of the manual operation part and ID information. The reservation management unit performs reservation management based on the wireless signal sent from the input device. The reservation management unit includes a clock unit, a storage unit, and a determination unit. The clock unit measures time. The storage unit associates reservation information containing a reservation start time, and the ID information with each other and stores them. The determination unit determines a reservation performance status based on a current time, the reservation start time, and the movement information.Type: GrantFiled: November 14, 2018Date of Patent: January 10, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yosuke Morita, Tomikazu Imai, Naoya Tsukamoto, Takayuki Okawa

Patent number: 8410773Abstract: A protection element (e.g., an arrester) protects a piece of equipment to be protected, from surge currents line terminals and an earth terminal. Surge current detection devices are provided on respective conductors connected to the arrester. Each of the surge current detection devices is to detect the surge current penetrated into a conductor for a short period of time, and includes a magnetic flux concentration member by which a magnetic flux produced by the penetrated surge current is concentrated in a given detection area at a high density, and a ferromagnetic material sheet positioned on the given detection area. The ferromagnetic material sheet includes a recording layer which is able to record and erase the penetration state of the surge current. A plurality of microcapsules are arranged in the recording layer, and each of the microcapsules contains a suitable liquid, and a plurality of magnetic particles suspended in the suitable liquid.Type: GrantFiled: September 13, 2010Date of Patent: April 2, 2013Assignee: Sankosha CorporationInventors: Takayuki Okawa, Yasuharu Yamada, Hideyoshi Saeki, Takuya Ouchi
