  • Patent number: 11781599
    Abstract: An inner member of a constant velocity joint includes holding portions that hold roller assemblies. Each of the holding portions includes a first orthogonal part and a second orthogonal part brought into contact with an inner roller of the roller assembly. When first and second transmission shafts are coaxially disposed, top parts of the first and second orthogonal parts are brought into contact with the inner circumferential wall of the inner roller. The first and second orthogonal parts are each sectioned into a first curved surface extending from the proximal end of the holding portion to the top part and a second curved surface extending from the top part to the distal end of the holding portion. The curvature radius of the second curved surfaces is larger than the curvature radius of the first curved surfaces.

  • Patent number: 11039037
    Abstract: Provided is an image processing apparatus for improving efficiency of a clipping process. The image processing unit is an image processing apparatus for a raster image processor (RIP) mounted in an image forming apparatus. An order acquiring unit acquires instructions for image processing. A determination unit, in a case where clipping is set according to the instructions acquired by the order acquiring unit, determines whether that clipping is to be in an inclusive mode or an exclusive mode, and in a case of the exclusive mode, calculates pixels that are to be protected in a frame for which image processing is to be performed, and sets a number of pixels necessary for a clipping process.

  • Patent number: 11017495
    Abstract: Embodiments improve processing of data by determining if a read-modify-write operation on a frame is necessary or not. Some frames may be converted into a block of 8 bpp data. There may be no need to read the destination since the unnecessary pixels may be protected by the byte-enables. The burst write transfer may be performed for the entire frame when it is 8 bpp depth. An original transfer frame may be split into smaller portions of the frame. One or more of the smaller frame portions may be converted into byte alignment thus obviating the need for the read function to be performed on the smaller frame portions. Accordingly, significant bits of data are no longer processed under this operation which speeds up the overall processing of data. Portions of transfer frames that may not be converted to 8 bpp may be processed with read-modify-write operations.

  • Patent number: 11010114
    Abstract: A memory control method generates write control data by predetermined areas by attaching processing priority data and a transfer ID, generates read control data for respective predetermined areas by attaching processing priority data and a transfer ID, stores the write control data and the read control data in an arbitration queue, executes an arbitration that determines a priority order of processing taking the write control data and the read control data that are stored in the arbitration queue as targets, and changes the processing priority data every time a predetermined time elapses. The arbitration raises a priority order taking the write control data or the read control data that includes the processing priority data as a timeout request when the processing priority data has passed a preliminarily set threshold by the change.

  • Patent number: 10977531
    Abstract: Provided is an image processing apparatus that improves performance of reading data of a RIP process. A multi-channel DMA (Direct Memory Access) controller performs reading or writing of stored data related to a RIP (Raster Image Processor). A FIFO (First In, First Out) is able to change a number of entries for each of the channels of the multi-channel DMA controller. An image processing control unit interprets the RIP order, and according to that order, changes the configuration of the number of entries for each of the channels, and controls processing of the data.
