  • Publication number: 20220383688
    Abstract: A currency deposit processor transfers currencies set in a deposit part one by one, discriminates the currencies by denominations, stores the currencies in denominations in a storage part without temporarily holding the currencies, and confirms the deposited currencies for each transaction. A control unit is provided that, when one storage part reaches its maximum capacity with both currencies confirmed up to a previous deposit transaction and currencies unconfirmed in a current deposit transaction and a failure occurs after the filling-up currencies are removed, performs a special control, in which data on the currencies unconfirmed in the current deposit transaction and included in the filling-up currencies is calculated as a partial confirmation, and the data on the currencies calculated as the partial confirmation is added and reflected at a time of another deposit transaction after a fault recovery process.

  • Patent number: 10344455
    Abstract: Operating information (a pilot pressure, a pump pressure, a hydraulic oil temperature, an engine rotational speed, an hour meter and the like) of a hydraulic excavator and use environment information (operator information) of the hydraulic excavator are transmitted to a center server together with body information (for example, a model, a type, a type number, an identification number and the like) from the hydraulic excavator. For example, when a hydraulic hose as a replaceable component of the hydraulic excavator is replaced, the replaceable component information (a replaceable component name and a replacement date) is transmitted to the center server from a computer for maintenance. The center server predicts a replacement time of the replaceable component (hydraulic hose) using the use environment information of the hydraulic excavator in addition to the operating information and the replaceable component information of the hydraulic excavator.
