  • Publication number: 20040239994
    Abstract: In the image forming apparatus, upon reception of a job containing a file to be printed, it is determined whether or not the job contains a template indicating that a plurality of files are to be merged. If it is determined that the job contains the template, then the job is stored in a storage section. Based on the template, it is analyzed whether or not all jobs containing files to be merged have been stored in the storage section. If it is determined that all the jobs have been stored in the storage section, then control is exerted based on the template so as to merge and print the files contained in all the jobs. Thus, a plurality of files can be automatically merged and printed, and therefore the workload on the user can be reduced.

  • Patent number: 6789035
    Abstract: A method of analyzing vibration in a longitudinal direction of a transmission belt that is trained around at least a drive pulley and a driven pulley in a power transmission system. The method includes the steps of using a vibration analysis model which involves a) generating data relative to the power transmission system; and b) calculating belt tension values, including a selected belt tension value, using the generated data. In the event that the selected belt tension value is calculated to be at or lower than a predetermined belt tension value, a correction is made in the selected belt tension value. The corrected, selected, calculated belt tension value is used to carry out the vibration analysis.
