  • Patent number: 12151208
    Abstract: The object of the present invention is to provide a stable isotope concentration method that reduces equipment cost and power without prolonging the start-up time and enables efficient concentration, and the present invention provides a stable isotope concentration method using multiple cascaded distillation columns (1st column to mth column; m is an integer of 2 or more), wherein the method includes a step in which one of gas and liquid is supplied from a position in the vicinity of the bottom of a (n?1)th column to a position in the vicinity of the top of an nth column (1<n?m), and the other of liquid and gas is returned from a position in the vicinity of the top of the nth column to a position in the vicinity of the bottom of the (n?1)th column; and wherein in each distillation column, when a flow rate of an ascending gas in the column is a first flow rate and a flow rate of the gas or the liquid supplied from a previous column or a next column is a second flow rate, the second flow rate is 4% by volume

  • Publication number: 20240062154
    Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a user that uses the printer. The server manages user stock data, which is data associating a stock of the cartridges held by the user with usage expiry dates thereof, and vendor stock data, which is data associating a stock of the cartridges held by a sales company providing the cartridge to the user with usage expiry dates thereof. When the sales company provides the cartridge to the user, the server determines, based on the vendor stock data and the user stock data, the cartridge of which usage expiry date is to be provided from among the stock of the cartridges held by the sales company.
