Publication number: 20240108332Abstract: A method of operating an articulatable surgical instrument. The method includes providing a rotary drive motion to a rotary drive member of a surgical end effector and converting the rotary drive motion to an upper axial motion and a lower axial motion at locations that are distal to the articulation joint. The method further includes applying the upper axial motion to an upper portion of a firing member and applying the lower axial motion to a lower portion of the firing member such that the upper axial motion and lower axial motion drives the firing member distally through the surgical end effector from a starting position to an ending position.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Gregory J.

Patent number: 11931855Abstract: Embodiments of the present disclosure generally relate to planarization of surfaces on substrates and on layers formed on substrates. More specifically, embodiments of the present disclosure relate to planarization of surfaces on substrates for advanced packaging applications, such as surfaces of polymeric material layers. In one implementation, the method includes mechanically grinding a substrate surface against a polishing surface in the presence of a grinding slurry during a first polishing process to remove a portion of a material formed on the substrate; and then chemically mechanically polishing the substrate surface against the polishing surface in the presence of a polishing slurry during a second polishing process to reduce any roughness or unevenness caused by the first polishing process.Type: GrantFiled: May 28, 2020Date of Patent: March 19, 2024Assignee: Applied Materials, Inc.Inventors: Han-Wen Chen, Steven Verhaverbeke, Tapash Chakraborty, Prayudi Lianto, Prerna Sonthalia Goradia, Giback Park, Chintan Buch, Pin Gian Gan, Alex Hung

Patent number: 10975623Abstract: A constant velocity joint for downhole power transmission has a first insert mounted in a radially extending drive shaft arm. The first insert engages a second insert mounted along a slot formed in a tubular housing disposed to receive the arm. The material for the two inserts may be different, having different galling properties. An insert may be shaped to have at least a flat surface, a cylindrical surface intersecting the flat surface, and a conical surface intersecting the cylindrical surface. The inserts may extend beyond the cavities in which they are mounted. Opposing cavity walls adjacent the cavity opening may be angled away from one another to permit the insert to flex under a load. The back wall of a cavity and back surface of an insert may be arcuate to permit rotational movement of the insert under a load.Type: GrantFiled: February 2, 2016Date of Patent: April 13, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Sandip Sonar, Hamid Sadabadi, Steven Park

Patent number: 10939793Abstract: The handheld cleaning apparatus provides a handheld cleaning apparatus comprising a removable handle, abrasive particles, angled edges, open channels, and a flexible yet durable surface for scouring. The invention creates an abrasive, or “sanding,” cleaning apparatus that is better suited for cleaning dirty surfaces than a traditional cleaning sponge. The handheld cleaning apparatus retains the abrasive outer shell of a sanding sponge but is much more flexible and water permeable than current sanding sponges. To this end, the handheld cleaning apparatus comprises open channels, or “blow holes,” that promote water flow through the sponge and give the sponge flexibility. The size and the number of the channels vary by the material or density of the sponge. The handheld cleaning apparatus, additionally, contains a handle that is removably attached, which enables the consumer the ability to connect one or more cleaning apparatuses together to form the desired shape and form of the cleaning apparatus.Type: GrantFiled: September 6, 2019Date of Patent: March 9, 2021Inventor: Steven Park
