Publication number: 20210053858Abstract: A control apparatus for controlling a thickness of a substrate, such as a glass ribbon. The control apparatus comprises a laser assembly and a shielding assembly. The laser assembly generates an elongated laser beam traveling in a propagation direction along an optical path. The shielding assembly comprises at least one shield selectively disposed in the optical path. The shield is configured to decrease an optical intensity of a region of the elongated laser beam. The shielding assembly is configured to change an intensity profile of the elongated laser beam from an initial intensity profile to a targeted intensity profile. A desired targeted intensity profile can be dictated by an arrangement of the shield(s) relative to the optical path, and can be selected to affect a temperature change at portions of the substrate determined to benefit from a reduction in thickness.Type: ApplicationFiled: March 5, 2019Publication date: February 25, 2021Inventors: Anatoli Anatolyevich Abramov, Anping Liu, Michael Yoshiya Nishimoto, William Anthony Whedon, Jae Hyun Yu

Patent number: 10612129Abstract: Provided herein are ion-implanted glass based articles with improved flaw suppression properties. The ion-implanted glass based articles generally have a final indent fracture threshold (IFT) load of at least 650 grams, and/or a scratch threshold force of at least 10 N, which represents at least 1.25-fold enhancement compared to the glass based article prior to ion-implantation. Factors affecting the efficacy of the ion implantation process can include the IFT load of the starting glass or glass ceramic substrate (native IFT load), ion type, ion dose, implant energy, beam current, and glass temperature.Type: GrantFiled: June 22, 2017Date of Patent: April 7, 2020Assignee: CORNING INCORPORATEDInventors: Sarko Cherekdjian, Benedict Osobomen Egboiyi, William Brashear Mattingly, III, Michael Yoshiya Nishimoto, Toshihiko Ono, Prakash Chandra Panda, Trevor Edward Wilantewicz

Patent number: 9315410Abstract: Methods and apparatuses for managing pulling forces applied to a glass ribbon in a draw apparatus are disclosed. The method includes applying a front-side and a rear-side drive torque to a glass. The method further includes calculating automatically with the at least one electronic controller a front-side and a rear-side average pulling force applied to the glass ribbon and corresponding to a first time period of at least one rotation of the front-side or rear-side stub roller, respectively. The front-side average pulling force and the rear-side average pulling force are compared to establish a pulling force differential between the front-side average pulling force and the rear-side average pulling force. One or more of the front-side drive torque or the rear-side drive torque are modified to decrease the pulling force differential between the front-side average pulling force and the rear-side average pulling force.Type: GrantFiled: April 28, 2015Date of Patent: April 19, 2016Assignee: CORNING INCORPORATEDInventors: Chris Scott Kogge, Gautam Narendra Kudva, Michael Yoshiya Nishimoto
