    Abstract: In a power transmission mechanism 20, a line connecting a center shaft 21 of a reference gear member 40 and a first shaft 44 of a first planetary gear member 42 and a line connecting the center shaft 21 of the reference gear member 40 and a second shaft 47 of a second planetary gear member 45 form a specific angle α. Rotation in one direction is prevented when a first carrier member 22 and a second carrier member 32 are relatively rotated in a direction to decrease the specific angle α. Further, a rotation prevention release unit is provided to release a prevention state of the rotation when the first carrier member 22 and the second carrier member 32 are relatively rotated in a direction to increase the specific angle α.

    Abstract: This method includes optimizing, by a gradient descent method, a first parameter used in back propagation processing and associated with XPM and a second parameter used in the back propagation processing and associated with SPM and XPM, wherein the back propagation processing is processing to estimate a waveform at a time of transmission by alternately calculating linear terms and nonlinear terms in a nonlinear Schrödinger equation after receiving an optical signal whose waveform shape changed in a transmission line and digitizing a waveform of the received optical signal, and correct, for each channel of plural channels in the transmission line at a time of wavelength-division multiplexing transmission, waveform distortion caused by SPM that occurs in the channel and waveform distortion caused by XPM that occurs in relation with channels other than the channel; and executing the back propagation processing by using the optimized first and second parameters.

    Abstract: An object is to detect a virus with high speed and high sensitivity. Provided is a virus detection method including using a well array formed by defining a plurality of wells adjacent to each other by a side wall stood on a substrate and detecting a virus in a test liquid based on the detection of light emission from the wells, wherein the well array has a test region in which a well formation area, which is an area of the substrate in a region where the wells are formed, is 5 mm2 or more, a total volume of the wells obtained by integrating individual volumes of the wells is 17 nL or more, a depth of the wells is 3.5 μm to 40 μm, an opening area of the wells is 18 μm2 to 1,700 μm2, a volume of the wells is 74 fL to 6,000 fL, and a thickness of the side wall between the wells adjacent to each other is 0.5 μm to 15 μm; and the detection of light emission from the wells is performed in a detection unit in which an observation visual field is fixed to have a size including the test region.

    Abstract: A risk of breakage of a sample holder can be reduced and a biochemical sample or a liquid sample can be observed easily and with a high observation throughput. A sample holder 101 holding a sample includes: a sample chamber including a first insulating thin film 110 and a second insulating thin film 111 that sandwich and hold the sample 200 in a liquid or gel form and face each other, a vacuum partition wall inside which the sample chamber holding the sample is fixed in a state in which the thin film is exposed to a surrounding atmosphere, and whose internal space is kept at a degree of vacuum at least lower than that of the sample room at the time of observation of the sample, a detection electrode 820 disposed to face the second insulating thin film in a state in which the sample chamber is fixed to the vacuum partition wall, and a signal detection unit 50 connected to the detection electrode. Before the surrounding atmosphere of the sample holder is evacuated from an atmospheric pressure to a vacuum, the charged particle beam device receives a detection signal from the signal detection unit via a connector and detects an abnormality of the sample chamber based on the detection signal.
