Abstract: This atomic resonator for causing a resonance frequency by CPT resonance includes: a gas cell having alkali metal atoms enclosed; a photodetector configured to detect light having passed through the gas cell and convert the light to an electric signal; a high-frequency oscillator configured to receive the electric signal and output the signal after a frequency thereof is divided by two; and a laser light source configured to modulate and introduce, into the gas cell, light based on the signal output from the high-frequency oscillator. The high-frequency oscillator has an injection-locked frequency divider circuit including an acoustic resonator as an oscillation element.

Abstract: An estimation apparatus is configured to be capable of accessing a model storage unit that stores a model built by machine learning, using, as training data, information on a predetermined sound and information relating to a signal source of a signal indicating a brain activity of a first subject presented with the predetermined sound, the model outputting information on a sound estimated to be recognized by the subject. The estimation apparatus acquires a brain wave of a second subject presented with the predetermined sound. The estimation apparatus estimates, based on a mode of the brain wave acquired, a signal source of the brain wave, from among a plurality of regions in a brain of the second subject. The estimation apparatus inputs the information relating to the signal source estimated to the model and acquires information on a sound estimated to be recognized by the second subject.

Abstract: An atomic beam is irradiated with a first, a second, and a third laser beam. The first laser beam and the third laser beam each have a wavelength corresponding to a transition between a ground state and a first excited state. The second laser beam has a wavelength corresponding to a transition between the ground state and a second excited state. First, atoms each having a smaller velocity component than a predetermined velocity in a direction orthogonal to the traveling direction of the atomic beam are changed from the ground state to the first excited state by the first laser beam. Subsequently, a momentum is provided for individual atoms in the ground state by the second laser beam, which removes the atoms from the atomic beam. Finally, atoms in the first excited state are returned from the first excited state to the ground state by the third laser beam.

Abstract: A physical state measurement apparatus includes a main solid material which generates fluorescence by excitation light from a light source part. A microwave application part applies microwaves to the main solid material so as to control an electron state of the main solid material. A detection part detects the physical state of an object to be measured by the fluorescence from the main solid material. A feedback part has a solid material for feedback and a control part and detects a difference in amplitude between operating points on a low-frequency side and a high-frequency side of a lowering portion of a spectrum amplitude centered on a resonance frequency of an electron spin resonance spectrum of fluorescence from the solid material for feedback and feedback-controls the microwave application part such that the difference becomes zero.

Abstract: Provided are a genome engineering method and a genome engineering kit which can efficiently engineer two or more alleles and are capable of engineering a relatively large region. The present invention provides a genome engineering method for engineering two or more alleles, comprising the steps of: (a) introducing the following (i) and (ii) to a cell comprising the chromosome: (i) a genome engineering system comprising a sequence-specific nucleic acid cleaving molecule targeting a target region in the chromosomal genome, or a polynucleotide encoding the sequence-specific nucleic acid cleaving molecule, and (ii) two or more donor DNAs for selective markers respectively having different selective marker genes (the number of types of the donor DNAs for selective markers are equal to or more than the number of the alleles that are subject to genome engineering); and (b) selecting the cell on the basis of all the selective marker genes carried by the two or more donor DNAs for selective markers.

Abstract: An actuator capable of attaining high output. The actuator includes a frame structure part that forms a frame structure surrounding a housing part, and a volume change part housed in the housing part. The volume change part increases a volume thereof by input of external energy. The frame structure part has a higher Young's modulus than a Young's modulus of the volume change part. The housing part has an anisotropic shape, with a maximum width in first direction of the housing part longer than a maximum width in second direction different from the first direction of the housing part.

Abstract: A low height type actuator capable of performing a two-dimensional motion includes a magnet structure that includes a first array in which the first and second magnets are alternately arranged in x-direction and a second array in which the first and second magnets are alternately arranged in y-direction, and first and second wirings. The first wiring crosses the first magnets included in the first array in y-direction, and the second wiring crosses the first magnets included in the second array in x-direction. According to the present invention, by making current flow in the first and second wirings, a two-dimensional motion can be achieved. Further, since the first and second wirings are each a planar wiring that crosses the magnets, height reduction can be achieved.
