  • Publication number: 20210380717
    Abstract: The present inventors produced a variety of bispecific antibodies that specifically bind to both F. IX/F. IXa and F. X, and functionally substitute for F. VIIIa, i.e., have a cofactor function to promote F. X activation via F. IXa. Among these antibodies, the antibody A44/B26 reduced coagulation time by 50 seconds or more as compared to that observed when the antibody was not added. The present inventors produced a commonly shared L chain antibody from this antibody using L chains of A44, and showed that A44L can be used as commonly shared L chains, although the activity of the resulting antibody is reduced compared to the original antibody (A44HL-B26HL). Further, with appropriate CDR shuffling, the present inventors successfully produced highly active multispecific antibodies that functionally substitute for coagulation factor VIII.

    Abstract: An image forming apparatus includes: an image carrier; an exposing device; a developing device with a developing roller; a development current detector that detects development current between the image carrier and the developing roller; and a hardware processor. Under an image forming condition, the hardware processor causes the exposing device to draw, on the image carrier, a development current-detection pattern that includes a solid image and a halftone image that follows the solid image in an image-conveying direction of the image carrier, causes the developing device to develop the development current-detection pattern, obtains information on a chronological change of the detected development current from the development current detector, and determines whether or not a ghost image due to the solid image occurs based on a temporary drop of the detected development current during development of the halftone image.

  • Patent number: 10949340
    Abstract: An overlaid erase block (EB) mapping scheme for a flash memory provides efficient wear-leveling and reduces mount operation latency. The overlaid EB mapping scheme maps a first type of EB onto one of a plurality of physical erase blocks, in a corresponding portion of the flash memory. The first type of EB includes a plurality of pointers. The overlaid EB mapping scheme also maps each of second and third types of EBs onto one of the physical EBs that is not mapped to the first type of EB. The second type of EBs store system management information and the third type of EBs store user data. When the flash memory is started up, the overlaid EB mapping scheme scans the corresponding portion to locate the first type of EB, locates the system EBs using the pointers, and locates the data EBs using the system management information.
