Abstract: A shutter speed determination device includes a motion detector and controller. The motion detector, on a block-by-block basis having a specified block size, performs detection processing of a motion vector for image data obtained by capturing a subject image. The controller, while reducing the block size, causes the motion detector to execute the detection processing repeatedly, each time executing the detection processing the controller finds a motion vector related value that changes in a same direction as a direction in which a magnitude of the motion vector changes, the controller determines a shutter speed used when capturing the subject image thereafter, based on the motion vector related value found.

Abstract: An electrode group includes a positive electrode, a negative electrode, a separator interposed between the positive electrode and the negative electrode, and a positive electrode lead electrically connected to the positive electrode. The positive electrode includes a positive electrode current collector and a positive electrode active material layer carried on each main surface of the positive electrode current collector. The positive electrode current collector has an exposed section that does not carry the positive electrode active material layer. The negative electrode includes a negative electrode current collector and a negative electrode active material layer carried on each main surface of the negative electrode current collector and has a first region and a second region. The mass of the negative electrode active material layer in the first region per unit area is smaller than the mass of the negative electrode active material layer in the second region per unit area.

Abstract: An arc detection device includes an obtainer and a determiner. The obtainer obtains a measurement result for a voltage applied to one target power supply line among a plurality of power supply lines to which power is supplied from a DC power source. The determiner determines, based on a component of a specific frequency band in the measurement result for the voltage obtained by the obtainer, whether there is a possibility of an arc fault occurring in the plurality of power supply lines.

Abstract: A positive electrode active material for a secondary battery contains a lithium metal composite oxide having a crystal structure based on a rock salt structure belonging to the space group Fm-3m. The lithium metal composite oxide contains at least one element A1 selected from the group consisting of Fe, Ca, Cr, Na, Al, Si, Mg, Cu, Zn, Pb, Sb, and W. The content of the element A1 in the lithium metal composite oxide is 10 ppm by mass or more and 1000 ppm by mass or less with respect to the total amount of the lithium metal composite oxide. A lattice constant a, which indicates a length in an a-axis direction of a crystal lattice of the lithium metal composite oxide is 4.09 Å or more and 4.16 Å or less.

Abstract: Disclosed is an electrolytic capacitor including: an electrode foil; and a lead member that is connected to the electrode foil. The lead member includes a lead wire and a plate-shaped tab portion that is provided at one end portion of the lead wire. The tab portion has a surface with an arithmetic average roughness Ra of 4 μm or more. The electrode foil and the lead member are connected by a crimping portion in an overlapping portion in which the tab portion and the electrode foil overlap each other when the electrode foil is placed on the surface of the tab portion.
