Patent number: 11978482Abstract: A data storage device has a closed loop extended park mode during spin down operation. A data storage device comprises a spindle motor configured to rotate one or more disks, and one or more processing devices. The one or more processing devices are configured to determine a value of current that is discharged from the spindle motor over time during a spin down of the spindle motor, and control a braking duty cycle for braking the spindle motor during the spin down such that the value of current discharged from the spindle motor over time does not exceed a selected current limit.Type: GrantFiled: January 17, 2022Date of Patent: May 7, 2024Assignee: Western Digital Technologies, Inc.Inventors: Brian Johnson, Jaesoo Byoun, Gaku Ikedo, Hideaki Ito, Naoyuki Kagami

Publication number: 20060121606Abstract: A cell culture method prepares first cells that are adhesion-dependent cells and monolayered or multilayered cells on a culture surface of a culture substrate, seeds second cells that are adhesion-dependent cells and are magnetized by allowing to have magnetic particles on the first cells, induces the second cells to a predetermined position on the first cells by magnetic force, and cultures the first cells and the second cells in a cell arrangement obtained by the magnetic induction. According to this cell culture method, after a cell sheet was prepared individually, cells can be multilayered without changing a temperature, peeling the monolayered sheet and laminating the monolayered sheets.Type: ApplicationFiled: November 14, 2005Publication date: June 8, 2006Applicants: Hiroyuki HONDA, JAPAN TISSUE ENGINEERING CO., LTD.Inventors: Akira Ito, Hiroyuki Honda, Takeshi Kobayashi, Minoru Ueda, Hideaki Kagami, Ken-ichiro Hata

Publication number: 20060063252Abstract: Epidermal keratinocytes not incorporating magnetic particles therein and epidermal keratinocytes incorporating magnetic particles therein were seeded in a 24-well ultra-low-attachment plate, and cultured for one day after a neodymium magnet was placed outside the bottom of the well. As a result, control epidermal keratinocytes not incorporating magnetic particles therein did not adhere to the bottom of the well and did not form an undifferentiated cell sheet. On the contrary, epidermal keratinocytes incorporating magnetic particles therein, while being attracted to the bottom of the well by magnetic force, formed a multilayered cell sheet. This cell sheet could be easily recovered by removing the neodymium magnet placed outside the bottom of the well, then bringing a magnet having a hydrophilic film attached thereto close to the cell sheet from upside and to attract it via this hydrophilic film, and lifting it.Type: ApplicationFiled: September 15, 2005Publication date: March 23, 2006Applicants: JAPAN TISSUE ENGINEERING CO., LTD.Inventors: Akira Ito, Hiroyuki Honda, Takeshi Kobayashi, Minoru Ueda, Hideaki Kagami, Ken-ichiro Hata, Hiroko Terasaki
