Publication number: 20230393310Abstract: A device comprising: a first substrate; and a second substrate bonded to the first substrate via an innermost bond, an outermost bond, and bonds between the innermost bond and the outermost bond, the second substrate comprising a through-hole and an axis extending through the through-hole. Each of the bonds has a strength, and the strength of the bonds increases sequentially from the innermost bond to the outermost bond. The strength of each bond is sufficiently low such that the bonds fail in response to liquid (within a cavity defined by the first substrate, a third substrate, and the through-hole of the second substrate) exerting pressure on the first substrate instead of the first substrate failing. Each of the bonds are configured to fail at approximately the same pressure exerted upon the first substrate by the liquid. Additionally disclosed is a method of manufacturing the device.Type: ApplicationFiled: October 7, 2021Publication date: December 7, 2023Inventors: Naigeng Chen, Stephan Lvovich Logunov, Weiwei Luo, Mark Alejandro Quesada, Bo Yang

Patent number: 9708136Abstract: Non-contact, liquid-ejecting bearings (3) are provided for conveying flexible glass sheets (13), such as LCD substrates, at high conveyance speeds, e.g., speeds of 15 meters/minute and above. The operating parameters and physical properties of the bearings satisfy at least one of the following conditions: (a) the average flow rate from the bearing's orifices (22) is in the range of 100-800 milliliters/minute/orifice; (b) the orifices' average horizontal pitch (P) is in the range of 20-55 millimeters; and/or (c) the orifices' average size (e.g., D0) is in the range of 1.0-4.5 millimeters. The bearings (3) can reduce the time-averaged, peak-to-peak variation in the spacing between a LCD substrate (13) traveling at 15 meters/minute and the face (20) of the bearing (3) to less than 100 microns, thus reducing the chances that the bearing (3) will lose control of the substrate (13) or that the substrate (13) will hit the bearing (3).Type: GrantFiled: September 13, 2011Date of Patent: July 18, 2017Assignee: Corning IncorporatedInventors: Gautam Narendra Kudva, Weiwei Luo, Yoshihiro Nakamura, Tetsuzou Yamada

Patent number: 9120700Abstract: Methods and apparatus are disclosed for etching flexible glass sheets (13) in which the sheets (13) are transported in a vertical or near vertical orientation past non-contact, liquid-ejecting bearings (3) which apply an etching solution (e.g., an aqueous NaF/H3PO4 solution) to one or both sides of the sheets (13). In certain embodiments, the uppermost liquid-ejecting bearing (3) is above the top edge of the sheet (13) and thus is able to apply etching solution to the top of the sheet. In other embodiments, a top shower (11), which includes a set of spray nozzles (21) located above and distributed along the length of the apparatus, is used to apply etching solution to the top of the sheet (13). Using the disclosed methods and apparatus, glass sheets (13) produced by a fusion process are provided which have areas greater than five square meters and average surface roughness values in the range of 0.5 nanometers to 1.1 nanometers.Type: GrantFiled: March 26, 2010Date of Patent: September 1, 2015Assignee: Corning IncorporatedInventors: Gautam Narendra Kudva, Chih Yuan Lu, Weiwei Luo, Yoshihiro Nakamura, Tetsuzou Yamada
