Abstract: A system for processing a waste lithium-ion battery includes: a first aqueous solution generator that includes a first elution tank storing water, and that immerses an active material taken out from the waste lithium-ion battery in the water in the first elution tank and subjects the active material to carbon dioxide bubbling in the first elution tank to generate an aqueous solution of pH 5.5 to 8.5, in which lithium contained in the active material is eluted; a first solid-liquid separator that removes a solid component from the aqueous solution generated by the first aqueous solution generator; a first crystallizer that causes lithium carbonate to be deposited from the aqueous solution, from which the solid component has been removed by the first solid-liquid separator; and a second solid-liquid separator that performs solid-liquid separation on slurry containing the lithium carbonate deposited in the first crystallizer to take out the lithium carbonate.

Abstract: A system includes one or more edge devices an integrated management apparatus configured to manage the one or more edge devices. The edge devices include a photodetector. The integrated management apparatus manages a first trained model and a first condition in association with each other. The first condition sets a condition for a photodetector used in generating the first trained model. The integrated management apparatus is configured to deliver the first trained model and the first condition to the edge devices.

Abstract: An accounting book automatic entering device, by which, when it is used for business processing in an accounting system, linked with an output device of a computer, trade data can be recorded in lines directly succeeding the last line of the preceding recording also on the rear side of book sheets of all the relating books and they can be conserved in the form of books after recording only by inputting one assortment so that they can be accessed at any time. A book holding shelf driving device locates a shelf of a book holding shelf corresponding to a shelf code, based on the shelf code in positional data stored in a memory device and an entry page selecting device driving section drives an entry page selecting device so as to select a specified book to fix it by means of a book selecting mechanism, to open the book at a target page by means of a page turning mechanism and for a printer to record output data on that page.
