  • Multiple-port print device
    Patent number: 8085424
    Abstract: A method that enables a multiple-port print device to perform efficient job management for each job even if the multiple-port print device is provided with parallel-processing-enabled multiple interfaces. The multiple-port print device includes a job boundary detection unit, a spool buffer, and a job management unit. By reading print job data stored in the buffer memory units from the multiple communication interfaces, and detecting the job start and end marks added to the print job data, the print job data is identified by each job boundary. The job management unit stores the print job data identified by the job boundary into the spool buffer as a spool file to spool-process the data between the spool buffer and the image processing unit.

    Abstract: A thrust race of a thrust roller bearing has a race portion and a cylindrical portion extending from the race portion in an axial direction. At a plurality of locations along a circumferential direction on the cylindrical portion, cutout portions are formed such that each of the cutout portions is recessed in the axial direction from a distal edge of the cylindrical portion toward the race portion. A protrusion is provided at a portion closer to the race portion from a bottom edge of each of the cutout portions such that the protrusion protrudes in a radial direction from the cylindrical portion toward a side away from the race portion. The protrusion serves as a race-retaining locking portion to prevent a race from moving out from a mating member on which the race is mounted.
