Patent number: 11548004Abstract: A method for producing a liquid reaction mixture containing a radioisotope, in particular, a radioactive composition, minimizes device contamination with radioactive substances and increase speed and accuracy with which droplets are mixed. The method for producing a radioactive composition includes placing at least one first droplet L1 containing a radionuclide and at least one second droplet L2 containing a labeling substance on at least two respective dimples 5 among dimples 5 on a front surface 4b of an insulating layer 4 of a liquid manipulation device 1, and obtaining a liquid mixture M by using a change in electrostatic force caused by changing voltage applied to the electrodes 3 to thereby cause a relative movement between the at least one first droplet L1 and the at least one second droplet L2 so that the at least one first droplet L1 and the at least one second droplet L2 are mixed together at any one dimple among the dimples 5.Type: GrantFiled: May 11, 2021Date of Patent: January 10, 2023Assignees: National Institute of Advanced Industrial Science and Technology, Kyoto Pharmaceutical UniversityInventors: Katsuo Mogi, Tohru Natsume, Shungo Adachi, Tomoya Inoue, Hiroyuki Kimura

Patent number: 8266401Abstract: Upon receiving a primary/secondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. In the event that yet to be transferred data is present, the secondary storage control device receives yet to be transferred data from the primary storage control device and updates a secondary volume. The primary storage control device then manages positions of updates to the primary volume due to host accesses to the primary volume occurring at the time of the secondary storage control device receiving the primary/secondary switching command onwards using a differential bitmap table.Type: GrantFiled: March 2, 2011Date of Patent: September 11, 2012Assignee: Hitachi, Ltd.Inventors: Koji Nagata, Shoji Kodama, Ikuya Yagisawa, Katsuo Mogi
