  • Patent number: 10487888
    Abstract: Since one end of a spring is received by a planar portion of a spring seat provided on any one of an outer plate and an inner plate, it is possible to support the spring with a planar member without machining a bottom wall face of the outer plate into a planar shape. Since the spring seat has seat guide portions that contact the outer plate, it is possible to suppress the fluctuation of the spring seat and the fluctuation of the spring by the seat guide portions, so it is possible to reliably prevent interference of the spring with its peripheral portion. Therefore, a load on the spring is reduced, so it is possible to improve the durability of a one-way clutch.

  • Patent number: 8576435
    Abstract: A print-document conversion apparatus includes a conversion-module activation section that activates, as a process, a conversion module for performing conversion processing for converting print-document data which is described in a page description language and which includes units of processing into print-image data. The conversion module includes a thread activation part, an assigning part, and a shared cache. The thread activation part activates conversion processing threads. The assigning part assigns the units of processing to the conversion processing threads, and causes the conversion processing threads to perform processing on the units of processing. The shared cache is shared by the conversion processing threads. When a conversion result obtained by converting an object included in the units of processing is stored in the shared cache, each of the conversion processing threads obtains the stored conversion result instead of obtaining the conversion result by converting the object.

  • Patent number: 8537396
    Abstract: A print document conversion apparatus includes a plurality of software-based conversion units and a controller. The plurality of software-based conversion units perform a software-based conversion process for converting print document data described in a page description language into page image data having a bitmap image format. Each of the plurality of software-based conversion units requests a hardware-based image processing apparatus that executes specific image processing in the software-based conversion process to execute the specific image processing, and generates the page image data including a result of the image processing executed by the hardware-based image processing apparatus in response to the request.
