Patent number: 10669057Abstract: The present invention is an apparatus and method for cutting individual label strips from a roll of label web utilizing a cutter assembly. A label cutter comprises a cutter assembly for continuously and independently controlling the rotational speeds of a rotating cutter shaft, a stationary shaft, and a label feed roller is provided. The length of the label strip is controlled by the distinct speed of rotation of a stationary knife, the stationary knife is rotatably coupled to the stationary shaft. At least one cutter blade is operatively associated to the rotating cutter shaft for cutting the label web. The stationary knife rotates with a speed of rotation different from the speed of rotation of the cutter blade to produce longer or shorter label length strips. The frequency at which the cutter blade meets the stationary knife is inversely related to the length of the label strip that is produced during cut off.Type: GrantFiled: June 6, 2017Date of Patent: June 2, 2020Assignee: Elum Inc.Inventors: Ranbir Singh Claire, Vinay Leeladhar Piratla, Karmen Claire

Patent number: 8367497Abstract: A method is provided that includes forming a trench isolation structure in a dynamic random memory region (DRAM) of a substrate and patterning an etch mask over the trench structure to expose a portion of the trench structure. A portion of the exposed trench structure is removed to form a gate trench that includes a first corner formed by the substrate and a second corner formed by the trench structure. The etch mask is removed and the first corner of the gate trench is rounded to form a rounded corner. This is followed by the formation of an oxide layer over a sidewall of the gate trench, the first rounded corner, and the semiconductor substrate adjacent the gate trench. The trench is filled with a gate material.Type: GrantFiled: October 31, 2007Date of Patent: February 5, 2013Assignee: Agere Systems LLCInventors: Nace M. Rossi, Ranbir Singh, Xiaojun Yuan
