  • Patent number: 9971980
    Abstract: The purpose of the invention is to provide a standard work time updating method and system in which a work time is declared by a worker without requiring an observer or the like and the reliability of the updated data of standard work time can be prevented from being degraded due to a worker's false or erroneous declaration. To achieve this purpose, for example, the standard work time updating system is configured as follows. When a reliability determination unit (24) determines that a work time required for work and declared by a worker is not departed from a predetermined range in the work time data distribution of the work stored in a database, a standard work time for the work is updated to a standard work time calculated from the declared work time, and otherwise, the standard work time is not updated.

  • Patent number: 9868283
    Abstract: A method of cleaning a liquid discharge head, which includes a heat generating resistor that generates thermal energy for discharging a liquid and a covering portion covering the heat generating resistor, includes alternately performing a first voltage application process and a second voltage application process multiple times, and reducing energy applied in the second voltage application process. The first voltage application process includes applying voltage between the covering portion and an electrode through the liquid to dissolve the covering portion in the liquid. The second voltage application process includes reversing relative polarities of the covering portion and the electrode in the first voltage application process and applying voltage between the covering portion and the electrode. Energy applied in the second voltage application process is reduced such that the energy applied is less than energy applied in the first voltage application process of an immediately preceding time.

  • Patent number: 9682552
    Abstract: When cleaning is performed to remove kogation, which is deposited on a heat acting portion, by causing an electrochemical reaction through application of a voltage between an upper electrode and an opposing electrode, a wiring located at a periphery of the opposing electrode occludes hydrogen generated during the cleaning, thereby causing hydrogen embrittlement. A unit configured to heat the wiring connected to the opposing electrode is provided, and is driven during the cleaning or after the cleaning, to thereby force hydrogen out of the wiring. Thus, the hydrogen embrittlement of the wiring is suppressed.
