  • Patent number: 11894854
    Abstract: An optical lattice clock includes a clock transition space having disposed therein an atom group trapped in an optical lattice, and a triaxial magnetic field correction coil for correcting the magnetic field of the clock transition space. Additionally, in a correction space that includes the clock transition space and is larger than the clock transition space, a photoreceiver promotes the clock transition of the atom group trapped in the optical lattice and acquires a clock transition frequency distribution for the correction space. Further, a corrector corrects the magnetic field of the triaxial magnetic field correction coil on the basis of the frequency distribution measured by the photo receiver.

  • Publication number: 20240012165
    Abstract: A gel dosimeter for radiation dosimetry includes a radically polymerizable monomer, a gelator, glucose, and glucose oxidase. Although a conventional polymer gel dosimeter contains a deoxygenating agent such as tetrakis(hydroxymethyl)phosphonium chloride, such a deoxygenating agent fails to exhibit sufficient effects. Thus, a more effective deoxygenation treatment technique has been required for a gel dosimeter.

  • Patent number: 11831257
    Abstract: A power generation device includes a filter holder that is a container filled with water and a filter member. The filter member is composed of porous glass in a form of a plate and arranged in the filter holder between a first space upstream from the filter member and a second space downstream from the filter member. The filter member allows hydrogen ions to pass therethrough more easily than hydroxide ions. The power generation device generates electric power based on a potential difference between the first space and the second space when a water flow from the first space toward the second space is produced in the filter member. The water flow flows along a direction of thickness of the filter member.
