Patent number: 12221588Abstract: There is provided a grease composition which is supplied between a plurality of lips provided in a sealing device that seals between a pair of members that rotate relative to each other, wherein the grease composition comprises a base oil (A), a thickening agent (B) and a rust preventive agent (C); a kinematic viscosity of the base oil (A) at 40° C. is 30 to 80 mm2/s; the thickening agent (B) is a diurea compound represented by Formula (1); and the composition comprises 5 to 15% by mass of the thickening agent (B) and 0.1 to 2.0% by mass of the rust preventive agent (C) based on the total of the grease composition. R1—NHCONH—R2—NHCONH—R3??(1) wherein R2 is a divalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and R1 and R3 are a linear or branched alkyl group having 8 to 22 carbon atoms. Thus, a grease composition is provided, which can suppress a torque difference due to a rotation direction and exhibits excellent sealing properties.Type: GrantFiled: March 8, 2022Date of Patent: February 11, 2025Assignees: UCHIYAMA MANUFACTURING CORP., KYODO YUSHI CO., LTD.Inventors: Masanori Shibayama, Koki Ando, Hiroyuki Saito, Michitaka Yoshihara

Publication number: 20250026854Abstract: 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: October 3, 2024Publication date: January 23, 2025Applicant: Chugai Seiyaku Kabushiki KaishaInventors: Kunihiro Hattori, Tetsuo Kojima, Hiroyuki Saito, Taro Miyazaki, Tetsuhiro Soeda
