Publication number: 20240134064Abstract: The present disclosure provides an electronic control device capable of suppressing variations in the position of a work machine calculated based on satellite signals received by a GNSS terminal due to changes in the GNSS communication environment, and eliminating the position error after improvement of the communication environment in a shorter time than before. The electronic control device includes: a positioning quality determination section 211 that determines whether the positioning quality is good or poor based on GNSS information; a traveling state determination section 212 that determines the traveling state, including a stop state, based on the velocity of the work machine; and a smoothing section 213 that performs smoothing processing to the GNSS information.Type: ApplicationFiled: May 30, 2022Publication date: April 25, 2024Inventors: Shinji ISHIHARA, Shiho IZUMI, Kenta NAKAGI

Publication number: 20220389746Abstract: A vehicle opening and closing body control device includes a full close control unit configured to cause first and second opening and closing bodies that are provided at an opening portion of a vehicle and execute opening and closing operations in opposite directions to execute the closing operations to a fully closed position. The full close control unit is configured to cause the second opening and closing body to execute the closing operation at an operation speed slower than that of the first opening and closing body.Type: ApplicationFiled: May 23, 2022Publication date: December 8, 2022Applicant: AISIN CORPORATIONInventors: Yuji NISHI, Isao HONDA, Kenta IZUMI, Takeshi NISHIKIBE

Publication number: 20220098235Abstract: To provide a method for purifying an antibody to a sufficient degree of purity for therapeutic use in humans by removing impurities contained in a solution efficiently while reducing production cost and the purification period in the purification of the antibody. It was found that an antibody can be reliably purified to a high degree of purity by an activated carbon material, regardless of the amounts or species of impurities co-present, and that high viral clearance can be attained reliably. Based on the finding, a treatment with an activated carbon material could be used in place of AEX chromatography achieving viral clearance in a step of purifying a therapeutic antibody using CHO cells. As a result, an antibody can be simply and effectively purified to a sufficient degree of purity for therapeutic use in humans compared to a conventional purification method, while reducing production cost.Type: ApplicationFiled: January 22, 2020Publication date: March 31, 2022Applicant: DAIICHI SANKYO COMPANY, LIMITEDInventors: Yumiko MASUDA, Yuka OGINO, Kota INOUE, Kenta IZUMI, Chie MUTO

Patent number: 10683690Abstract: A vehicular opening/closing body control device includes a braking controller configured to apply a braking force to an opening/closing body, a full-closing detection unit configured to detect that the opening/closing body is in a fully-closed state, and a failure detection unit configured to detect failure of a latch mechanism provided on the opening/closing body. The latch mechanism is provided with a pawl switch, which is switched between ON and OFF states in conjunction with operation of a pawl. The failure detection unit detects, based on the ON and OFF states of the pawl switch, occurrence of an engagement failure in which the latch mechanism fails to hold the opening/closing body in the fully-closed state. The braking controller executes braking control for applying the braking force to the opening/closing body when the engagement failure is detected in the latch.Type: GrantFiled: March 16, 2018Date of Patent: June 16, 2020Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Yoshiki Bito, Kenta Izumi, Takeshi Nishikibe
