Patent number: 11925979Abstract: Large steel ingot casting is accomplished with a top suspended induction heating device supplied with variable power and variable frequency from a power source. By the induction heating and stirring provided by the top suspended induction heating device, metal solidification advances progressively upwards from bottom to top, and the upper molten metal in a riser part compensates for shrinkage of the lower solidified metal in the main part. Inclusions are selectively moved out of the molten metal by a variable electromagnetic stirring force and the formation of casting defects is suppressed.Type: GrantFiled: November 19, 2021Date of Patent: March 12, 2024Assignee: Inductotherm Corp.Inventors: Satyen N. Prabhu, Mike Maochang Cao, Nier Wu

Publication number: 20240027849Abstract: The present application provides a display panel and a display device. A blue sub-pixel of the display panel has more display domains than a red sub-pixel and a green sub-pixel. The blue sub-pixel has a differential design while the red sub-pixel and the green sub-pixel maintain their original designs. Under a precondition of ensuring light transmittance, a lower proportion of light is emitted by the blue sub-pixels in a displayed screen when viewed at wide viewing angles, so that the present application can alleviate a color shift problem at wide viewing angles of a conventional liquid crystal display.Type: ApplicationFiled: July 21, 2021Publication date: January 25, 2024Applicant: TCL China Star Optoelectronics Technology Co., Ltd.Inventor: Wu CAO
