Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor [1] at Diablo Data Systems.It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster.
Its products include printers, multifunction printers, desktop computers, consumer and industrial sewing machines, large machine tools, label printers, typewriters, fax machines, and other computer-related electronics. [2] [3] Brother distributes its products both under its own name and under OEM agreements with other companies.
Line matrix printers are capable of printing much more than 1000 cps, resulting in a throughput of up to 800 pages per hour. A variation on the dot matrix printer was the cross hammer dot printer, patented by Seikosha in 1982. [37] The smooth cylindrical roller of a conventional printer was replaced by a spinning, fluted cylinder.

The Selectric typewriter was introduced on 31 July 1961. Its industrial design is credited to influential American designer Eliot Noyes.Noyes had worked on a number of design projects for IBM; prior to his work on the Selectric, he had been commissioned in 1956 by Thomas J. Watson Jr. to create IBM's first house style: these influential efforts, in which Noyes collaborated with Paul Rand ...
Roller burnishing is used in the production of some crankshafts. A dual roller (cylindrical) tool is moved into the thrust bearing journal of a crankshaft, while the crankshaft is spinning the tool is indexed (so each roller is perpendicular to the thrust surface while backing each other up) deforming the surfaces. So the diameters of each ...
