Publication number: 20240055641Abstract: [Task] Provided is a proton conductor and a manufacturing method thereof that are suitable for the use in a temperature range between 200° C. and 600° C. [Solution] A proton conductor has electric conductivity of 0.01 S/cm or more at 300° C., wherein a portion of lithium ions of Li14?2xZn1+x(GeO4)4 is substituted with protons. The x is a number equal to or more than 0. 40% to 70% inclusive of movable lithium ions contained in Li14?2xZn1+x(GeO4)4 may be substituted with the protons. 50% to 60% inclusive of movable lithium ions contained in Li14?2xZn1+x as (GeO4)4 may be substituted with the protons. A manufacturing method of a proton conductor comprises a process of substituting a portion of lithium ions with protons by immersing Li14?2xZn1+x(GeO4)4 in a non-aqueous organic solvent containing acid.Type: ApplicationFiled: August 12, 2021Publication date: February 15, 2024Inventors: Yoshimi OKADA, Takuo YASUNISHI, Kenichi IMAGAWA, Koichi EGUCHI, Toshiaki MATSUI, Hiroki MUROYAMA, Takashi OZEKI

Patent number: 10945689Abstract: A mobile radiation generator includes an arm part on which an irradiation section is mounted. The height of the irradiation section is changed in a case in which the arm part is rotated. A spring generates negative rotational moment in a negative direction where the irradiation section is displaced upward against positive rotational moment that acts on the arm part in a positive direction due to own weight of the irradiation section and the like. A friction mechanism is built in a pillar. In a case in which the magnitude of the positive rotational moment and the magnitude of the negative rotational moment are different from each other, the friction mechanism generates a frictional force acting in a direction opposite to a direction where the arm part is to be rotated due to a difference between the positive rotational moment and the negative rotational moment and cancelling the difference.Type: GrantFiled: September 18, 2017Date of Patent: March 16, 2021Assignee: FUJIFILM CorporationInventor: Koichi Eguchi

Patent number: 10525935Abstract: In a door control system, a reservation signal is transmitted when a user operates a mobile device and reserves opening a door, a control device transmits a reservation acceptance signal and starts transmitting a response request signal upon receipt of the reservation signal. When the mobile device receives the reservation acceptance signal, a mobile device memory stores information indicating that the reservation is accepted and authorized and a notification unit notifies the user of authorization. When the mobile device receives the response request signal, the mobile device transmits a response signal including the stored information indicating authorization. When the control device receives the response signal including the information indicating authorization in response to the response request signal, a controller performs at least one of unlocking or opening the door.Type: GrantFiled: October 9, 2017Date of Patent: January 7, 2020Assignee: OMRON AUTOMOTIVE ELECTRONICS CO., LTD.Inventors: Yosuke Tomita, Yosuke Kajima, Hirofumi Ohata, Koichi Eguchi, Yuki Tokuyama
