Patent number: 11948604Abstract: According to an embodiment, a magnetic disk device includes a magnetic disk, a magnetic head that accesses the magnetic disk, a motor that moves the magnetic head, a ramp, a motor driver, and a processor. When a voltage value of a power supply voltage falls below a first threshold, the motor driver starts a retract operation of retracting the magnetic head to the ramp by controlling a voltage applied to the motor. When the voltage value of the power supply voltage falls below a second threshold larger than the first threshold, the processor transmits an instruction related to applying a brake to the movement of the magnetic head to the motor driver.Type: GrantFiled: March 10, 2022Date of Patent: April 2, 2024Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ELECTRONIC DEVICES & STORAGE CORPORATIONInventors: Hideki Hironaka, Kenji Itou

Patent number: 9343986Abstract: In a power converter, a driver drives a switching element using a manipulated variable therefor to convert input power into output power. A first measuring unit measures a value of a first electric parameter depending on the input power. A first determiner determines, from the measured value of the first electric parameter, a first feedback controlled variable. A second measuring unit measures a value of a second electric parameter indicative of the output power, and a calculator calculates, based on the measured value of the second electric parameter and a command value for the second electric parameter, a second feedback controlled variable. A selector selects, based on the measured value of the first electric parameter, one of the first feedback controlled variable and the second feedback controlled variable. A second determiner determines the manipulated variable using the selected one of the first and second feedback controlled variables.Type: GrantFiled: January 16, 2014Date of Patent: May 17, 2016Assignees: DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Norihito Kimura, Hideki Itou, Yuji Hayashi

Patent number: 9160238Abstract: In a power converter, a deviation calculator calculates, in each cycle, a deviation between a value of an input electrical parameter of a switch circuit and a target value selected by a selector in a previous cycle. The input electrical parameter depends on the input power to the switch circuit. A second calculator calculates, in each cycle, a value of a second feedback controlled variable such that the value of the second feedback variable approaches the value of the input electrical parameter. A controller controls, in each cycle, the selector to select one of the value of the first feedback controlled variable and the value of the second feedback controlled variable as the target value for the next cycle according to the deviation calculated by the deviation calculator.Type: GrantFiled: January 22, 2014Date of Patent: October 13, 2015Assignee: DENSO CORPORATIONInventors: Hideki Itou, Norihito Kimura, Yuji Hayashi
