Abstract: A processor of an information processing device acquires first device information including failure information related to each client terminal, and failure resolution information, and generates a failure database containing the failure information and the failure resolution information associated with each other. The processor acquires second device information related to each client terminal at a predetermined time interval, and performs, in the failure database, primary search for the failure resolution information based on information for search for searching for the failure resolution information. The processor performs, in the second device information, secondary search for the information of the client terminal specified by the information for search, extracts specific information of the specified client terminal from the failure resolution information by extracting information corresponding to a result of the secondary search from a result of the primary search, and transmits the specific information to the specified client terminal by the output unit.

Abstract: A disclosed solid electrolytic capacitor includes a capacitor element, a lead terminal and a lead terminal that are electrically connected to the capacitor element, and an exterior body that seals a portion of the lead terminal, a portion of the lead terminal, and the capacitor element. The exterior body includes a resin part containing a resin. The resin has a glass transition point Tg of 140° C. or less, where the glass transition point Tg is a temperature of the resin part at which a loss modulus measured by nanoscale dynamic viscoelastic measurement using a nanoindentation method changes from an increasing state to a decreasing state. The hardness of the resin part measured by the nanoindentation method is 0.08 GPa or less in a temperature range from the glass transition point Tg to 260° C. inclusive.

Abstract: The computing circuit detects a plurality of character regions in the input image, each of the plurality of character regions including a character or a character string made of a plurality of characters. The computing circuit determines a direction of the character or the character string in each of the character regions. The computing circuit recognizes the character or the character string in each of the character regions. The computing circuit generates a connected region by connecting at least two character regions including the character(s) or the character string(s) having a same direction, the at least two character regions being close to each other at a distance less than a threshold. The computing circuit connects the character(s) or the character string(s) included in the connected region to each other.

Abstract: A packaging cushion material, to be housed in a box body together with an article, includes a holder portion adapted to accommodate the article, a holder support portion adapted to support the holder portion, and a hinge portion connecting the holder portion and the holder support portion to each other. The holder portion, the holder support portion, and the hinge portion are integrally molded as one component. When the packaging cushion material is housed in the box body in a state where the hinge portion is folded, the holder support portion supports the holder portion with the hinge portion interposed therebetween such that the holder portion is displaceable.

Abstract: A motor control device includes a control unit and a generation-method changer. The control unit generates a driving signal for driving a motor in accordance with a command signal and an encoder signal and outputs the generated driving signal to the motor, the command signal being a signal for setting the position of a moving part connected to the motor to a target position, the encoder signal indicating the position of the motor detected by an encoder. The generation-method changer changes a method used by the control unit to generate the driving signal in accordance with a position sensor signal indicating a detected target position that is the target position detected by a position sensor mounted on the moving part.

Abstract: A zoom lens system includes: a first lens group having positive power; a second lens group having negative power; a third lens group having positive power; a fourth lens group having positive power; a fifth lens group having negative power; and a following lens group following the fifth lens group. The first to fifth lens groups and the following lens group are arranged in this order such that the first lens group is located closest to an object and that the following lens group is located closest to an image. While the zoom lens system is zooming, intervals between the respective lens groups change. While the zoom lens system is focusing from an infinity focus point through a shortest shooting range, a plurality of negative lens groups included in the fifth lens group and the following lens group move.
