  • Patent number: 7722331
    Abstract: An air-compressing apparatus has four compressors individually supplying compressed air to a tank having a pressure sensor. The pressure sensor is connected to control circuits of the compressors. The control circuits compute times needed for the tank pressure to reach minimum and maximum pressures, respectively, of the tank by using the detected tank pressure and also using a tank pressure change value. The computed time values correspond to the consumption of compressed air. Thus, the control circuits can control the number of compressors to be operated according to the consumption of compressed air.

  • Patent number: 7703072
    Abstract: Reliability is evaluated in constructing a component based-on application and an application for realizing reliability required can be constructed efficiently. A run-time history such as an occurrence frequency of errors, a recovery time required at error occurrence, and a processing capacity at preventive maintenance is added per software component to a run-time history list having been recoded per execution environment such as an application ID, combined component IDs, and executed hardware ID. From these pieces of information, an interval of performing preventive maintenance recommended per software component during system construction is calculated. By comparing reliability per software component and reliability required for the system, advisability is determined and conformance is evaluated. An execution schedule for preventive maintenance and a processing capability are calculated about the entire component-based application created by combining the software components.

  • Publication number: 20100085617
    Abstract: An image processing apparatus that performs processing for converting image data of an original document into data for an output apparatus is provided. The image processing apparatus includes: a correcting unit that applies a change to the image data so as to ensure that a color that is located in a region in a color space that represents color values of an image is outputted in one color of a recording material; and a corrected data outputting unit that outputs the image data corrected by the correcting unit. The region is defined by excluding a second region from a first region. The first region is a region that includes each color value obtained as a result of reading a sample by means of the reading apparatus. The second region is a region in which a color that should not be outputted as the one color is located.
