Patent number: 11216367Abstract: A power-supply device and an electronic device including the relate to technology for a data storage device. The electronic device includes a power-supply device and a controller. The power-supply device generates a sudden power loss (SPL) detection signal in a sudden power off (SPO) state by detecting a level of an external power, generates a charging sense signal indicative of a charging capacity of an auxiliary power-supply circuit, divides the charging capacity into a plurality of charging levels, detects a level of the charging capacity, and generates a charging sense signal indicating a charging level of the auxiliary power-supply circuit in response to the detected charging level. The controller stores flushing information in at least one non-volatile memory device when the SPL detection signal is activated, and variably adjust an amount of storage in the non-volatile memory device in response to the charging sense signal.Type: GrantFiled: September 14, 2020Date of Patent: January 4, 2022Assignee: SK hynix Inc.Inventors: Jeong Su Park, Yong Seok Oh, Joo Il Lee

Patent number: 6545403Abstract: A color cathode ray tube having an improved electron gun, includes a quadrupole lens consisting of an independent static electrode having a static voltage applied thereto and a dynamic electrode which is disposed opposite to the independent electrode and having a dynamic voltage applied thereto. A dynamic strong quadrupole lens effect is obtained by applying a modulation voltage or parabola voltage to the dynamic electrode. When electron-beam-passing-apertures in electrodes of a main lens are enlarged, each axial distance between the axes of three electron-beam-passing-apertures of the static electrode opposite to the dynamic electrode in the strong quadrupole lens forming electrodes is offset and the sizes of the opposite side electron-beam-passing-apertures are increased by the offset axial distance.Type: GrantFiled: July 23, 1999Date of Patent: April 8, 2003Assignee: Orion Electric Co., Ltd.Inventor: Joo Il Lee

Patent number: 6255767Abstract: An electron gun has a plurality of grid electrodes for focusing electron beams radiated from cathodes, at least one of said grid electrodes having a cylindrical body containing a plate member. The plate member has a central electron-beam-passing-aperture and two side apertures. At least one of the two side apertures is contoured by a first circular arc and a second circular arc, two first vertical lines respectively extending outward from either ends of the first circular arc, two second vertical lines respectively extending outward from either ends of the second circular arc, and two connecting lines respectively connecting each of outer ends of the first vertical lines to each of outer ends of the second vertical lines. The electron gun improves the degree of freedom in controlling shapes of beam spots focused on a phosphor screen, thereby heightening the resolution of the cathode ray tube.Type: GrantFiled: November 25, 1998Date of Patent: July 3, 2001Assignee: Orion Electric Co., Ltd.Inventors: Joo Il Lee, Yu Sung Nam
