  • Publication number: 20200379672
    Abstract: An information processing apparatus of the present invention is an information processing apparatus that manages a hierarchical storage including a primary storage and a secondary storage. The information processing apparatus includes an acquisition unit that acquires a measurement value obtained by measuring a power consumption amount of each of the primary storage and the secondary storage, a determination unit that determines whether or not to move a file between the primary storage and the secondary storage, on the basis of a condition for determining a storage destination of the file to be stored in the hierarchical storage with use of the measurement value, the size of the file, and the access interval time of the file, and a relocation unit that moves the file between the primary storage and the secondary storage in accordance with the determination.

  • Patent number: 10655736
    Abstract: In an embodiment, in a sliding component, a sliding face of a stationary-side seal ring 6 has a fluid circulation groove 10 communicating with a high-pressure fluid side via an entrance portion 10a and an exit portion 10b. A rotating-side seal ring 5 has a larger outer diameter and a smaller inner diameter than the seal ring 6. A groove 15 into which a claw is loosely fitted is provided on an outer periphery of the seal ring 5. A width of the groove 15 is smaller than a distance between the portion 10a and the 10b in the circumferential direction. WMR/WSR is set within a range of 0.75<WMR/WSR<1.4 (WMR is a face width between an inner diameter of the groove 15 and an inner diameter 6b of the sliding face; WSR is a face width of the sliding face).

  • Patent number: 10658855
    Abstract: A transformer less battery charger system. In one embodiment, the battery charger system includes input terminals for receiving an AC voltage, output terminals for receiving terminals of a rechargeable battery pack, and a non-isolated DC-DC converter coupled between the input terminals and the output terminals. A device is also coupled somewhere between the input terminals and the output terminals. The device is configured to selectively and indirectly couple the input terminals to the output terminals. More particularly, the device indirectly couples the input terminals to the output terminals when the rechargeable battery pack terminals are received by the output terminals, and the device indirectly decouples the input terminals from the output terminals when the rechargeable battery pack terminals are separated from the output terminals.

  • Patent number: 8867057
    Abstract: This invention relates to a printing system configured to output printing media having undergone print processing by a print apparatus to a plurality of destinations including a specific destination which has a structure allowing an operator to take out the printing media. In the system, output of printing media to the specific destination is restricted while the operator takes out the printing medium outputted to the specific destination, and in case that the number of printing media necessary for a job processed by the print apparatus is smaller than a predetermined number, the system is controlled not to output to the specific destination a printed material formed from printing media smaller in number than the predetermined number. This invention can achieve efficient printing by controlling not to stop the print operation of the system as much as possible.

  • Patent number: 8373873
    Abstract: A data processing apparatus allocates a page number in a record to each of a plurality of records of a variable data print job and performs a preflight check every page number. After that, the data processing apparatus extracts the records in which the same kind of (or same) problem has occurred in a page of the same page number from the records included in the variable data print job. The data processing apparatus calculates a ratio of the extracted records to all records having the page of the page number and presumes whether the problem relates to a master object or relates to a variable object according to the ratio. The data processing apparatus displays whether the problem in the page relates to the master object or relates to the variable object every page having the problem.

  • Patent number: 8139243
    Abstract: A print job often includes secret information, and information may suffer sniffing from devices that execute distributed processing of jobs, or on the network. Therefore, executing the distributed processing of a print job including secret information reduces the robustness in terms of security protection. Hence, upon reception of a job, a task manager (TM) issues, to a dynamic job scheduler (DJS), a request of target devices of distributed processing according to a security level indicating the importance level of data included in that job. The DJS notifies the TM of the target devices, and the TM transmits divided jobs to the target devices.

  • Patent number: 7999963
    Abstract: A CPU of an image forming apparatus, such as a color electrophotographic copying apparatus, reads print step information from a memory, such as a USB memory, that stores print image data and print step information relating to a plurality of print steps for producing a print of the print image data and a progress state of the print steps. The CPU updates the progress state of the print steps stored in the memory subsequent to the print step being performed by a printer in the image forming apparatus, displays a next print step to perform based on the read print step information, and controls the printer. The image forming apparatus thus avoids leaks of the print data, and prevents useless printing and erratic job processing. Thus, even an inexperienced operator can provide sophisticated high quality print service using the image forming apparatus.
