Abstract: An information processing device includes a relationship identifier that identifies a first causal relationship based on data of a connection state and an order relationship of machineries that constitute a manufacturing line, the first causal relationship being between the machineries in a process performed on the manufacturing line, a relationship acquirer that acquires a second causal relationship between events related to the machineries in a process performed on the manufacturing line according to user setting, and a relationship synthesizer that generates a third causal relationship obtained by integrating the first causal relationship and the second causal relationship.

Abstract: A method includes: a step of acquiring a captured image of a workplace captured by a camera that is installed above the workplace and has an imaging direction substantially vertically downward; a step of detecting a partial image representing a wearing object worn by a worker from the captured image acquired; a step of acquiring position information indicating a position where the partial image is detected in the acquired captured image; acquiring, for the acquired captured image, adjustment information for displaying the captured image in which brightness is adjusted; and outputting, for the acquired captured image, the position information acquired from the captured image and the adjustment information acquired for the captured image.

Abstract: At work sites, using imaging data and work flows to find points to improve in work processes requires considerable time. A work management device includes: a history acquisition part that acquires an implementation result information history for workers in a work process group; a classification processing part that classifies at least some of the implementation result information into any of a plurality of classes; and a class determination part that determines each classified class to be a standard class in which no issues occur during work or a non-standard class in which issues may occur during work.

Abstract: Production is performed without lowering the operating rate of a facility that operates with an auxiliary operation performed by a human and the operating rate of an operator to improve productivity. A production management support system supports management of a production process including a process assigned to an operator and a process assigned to a facility including an auxiliary operation performed by a human.

Abstract: Data indicating a first time period during which a workpiece as a work object in each of a plurality of work processes stays in a state in which substantial work is possible, a second time period during which a worker stays in a worker area, and a work cycle are acquired. A work type identifier is provided that identifies a work type of each time range included in the second time period based on a relationship between the first time period and the second time period. A time calculator is provided that, with respect to at least one work process, calculates a sum total of time ranges corresponding to at least one work type included in one work cycle.

Abstract: Provided in the present disclosure are a controller, a method for controlling controller, learning device, and a storage medium. Correct/incorrect determination of a transfusion tube is efficiently performed during a changeover. Motor shaft information of a driving motor, which drives an actuating portion sequentially compressing and relaxing a transfusion tube of a transfusion device, is obtained, and the correctness/incorrectness determination of the transfusion tube is performed on the basis of the motor shaft information.

Abstract: In the joining structure of the solid electrolytic element, terminals connected to the heating element and the electrodes are attached through metallic oxide layers onto the solid electrolytic layer. The thermal conductivity coefficient of the metallic oxide layers is larger than that of the solid electrolytic layer. The thermal expansion coefficient of the metallic oxide layers is the same as or smaller than that of the solid electrolytic layer. Consequently, when the lead wires are soldered to the terminals, heat is quickly conducted to the terminals, enhancing the fluidity and the solderability of the soldering material. Since excess heating is not required for soldering, the solid electrolytic layer is prevented from deteriorating due to heat. Since a low-melting solder is not used, the joining structure has high heat resistance. Moreover, during soldering, the metallic oxide layers do not detach from the solid electrolytic layer due to heat.

Abstract: An oxygen sensor including a detection element with electrodes for detecting an oxygen partial pressure, a metal member for containing the detection element, and an insulation spacer for supporting the detection element. The oxygen sensor further includes an insulating layer for covering the surface of a recess defined by the detection element, the metal member, and the insulating spacer, thus preventing the deterioration of insulation between the electrodes of the detection element and the metal member. The oxygen sensor of this invention can accurately detect the oxygen partial pressure for a long time.
