Abstract: A method for producing an aluminum material, including: providing an electrolytic cell in which an anode electrode containing 0.01 to 30% by mass Si and Al and a cathode electrode are immersed in an electrolytic solution and depositing aluminum on the cathode electrode by energizing the anode electrode and the cathode electrode in the electrolytic solution.

Abstract: Avoiding the discharge of lightweight articles as much as possible while improving the yield. A combination weighing device (1) comprises: a transport unit (10, 11) configured to transport an article (100) supplied from an outside; a plurality of hoppers (13) configured to perform a measurement while temporarily holding the article (100) transported by the transport unit (10, 11) to acquire a mass value of the article (100); and a controller (5) configured to select a combination of the hoppers (13) to discharge the article (100) from the hopper (13) included in the selected combination based on a target mass value set in advance and the mass value acquired in each of the plurality of hoppers (13). The target mass value is a value obtained by adding a correction value to a mass value requested by a user, and the correction value is set to a different value depending on a number of the hoppers (13) used for the combination.

Abstract: A work assistance system that assists a worker working in a factory equipped with a plurality of processing apparatuses includes: a display unit having portability and configured to display information provided to the worker, an imaging unit having portability and configured to capture an image of the processing apparatus; a display controller configured to control a content of information displayed on the display unit; and an identifying unit configured to identify from which direction the processing apparatus is captured by the imaging unit, based on data captured by the imaging unit. When the direction identified by the identifying unit is a predetermined direction, the display controller causes the display unit to display an adjustment screen for adjusting an operation parameter of the processing apparatus captured by the imaging unit.

Abstract: A method for manufacturing metal nanoparticles includes adding at least one metal salt to an ionic liquid to form metal ions in the ionic liquid, and heating the ionic liquid to which the metal salt has been added to thermally reduce the metal ions.

Abstract: A packaging apparatus includes a conveying unit that conveys a continuous film in a first direction with an article placed on a first portion of the film, and folds back in a second direction opposite to the first direction a second portion of the film ahead of the first portion with respect to the first direction, sealing parts that seal the first portion and the second portion to form a bag body containing the article, and a cutter that cuts the film.
