Norio Taniguchi (谷口 紀男, Taniguchi Norio, May 27, 1912 – November 15, 1999) was a professor of Tokyo University of Science.He coined the term nano-technology in 1974 [1] to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: "Nano-technology"
This is a list of telephone area codes of Pennsylvania. In 1947, the American Telephone and Telegraph Company divided Pennsylvania into four numbering plan areas (NPAs) and assigned distinct area codes for each. Since 1995, several relief actions in form of area code splits and overlays have expanded the list of area
Japanese scientist Norio Taniguchi of Tokyo University of Science was the first to use the term "nano-technology" in a 1974 conference, [12] to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer. His definition was, "'Nano-technology' mainly consists ...
The term "nano-technology" was first used by Norio Taniguchi in 1974, though it was not widely known. Inspired by Feynman's concepts, K. Eric Drexler used the term "nanotechnology" in his 1986 book Engines of Creation: The Coming Era of Nanotechnology , which proposed the idea of a nanoscale "assembler" that would be able to build a copy of ...
Area codes are also assigned for non-geographic purposes. The rules for numbering NPAs do not permit the digits 0 and 1 in the leading position. [1] Area codes with two identical trailing digits are easily recognizable codes (ERC). NPAs with 9 in the second position are reserved for future format expansion.
Area codes 215, 267, and 445; Area code 412; Area code 445; Area codes 570 and 272; Area codes 610, 484, and 835; Area codes 717 and 223; Area code 724; Area codes 814 and 582; Area code 835; Area code 878
Map of previous proposed split of 814 with 582, showing county lines. When numbering pool exhaustion became a threat in the 2000s, the Pennsylvania Public Utility Commission (PUC) approved a numbering plan split in December 2009, that would have assigned area code 582 to most of the northwestern portion of the territory, including Erie, by 2012.
