Patent number: 11483419Abstract: A protocol converter is configured to be connectable between a field device and a device control apparatus and includes a converter controller and a converter storage. The converter controller acquires field data from the field device, writes the field data to the converter storage as a data set formed by a plurality of pieces of data and changes the value of a first counter controlled by the converter controller when the value of the first counter and the value of a second counter controlled by the device control apparatus are equal, and stops an operation to write the field data to the converter storage when the value of the first counter and the value of the second counter are different.Type: GrantFiled: July 31, 2020Date of Patent: October 25, 2022Assignee: YOKOGAWA ELECTRIC CORPORATIONInventors: Shohei Toriumi, Koji Nagatomi, Hiroaki Nakajima, Hiroyuki Saito

Publication number: 20220213217Abstract: 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.Type: ApplicationFiled: March 21, 2022Publication date: July 7, 2022Applicant: Chugai Seiyaku Kabushiki KaishaInventors: Kunihiro Hattori, Tetsuo Kojima, Hiroyuki Saito, Taro Miyazaki, Tetsuhiro Soeda
