The company was founded in 1883 [1] in Chicago as a lumber company by Albert Blake Dick (1856 – 1934). It soon expanded into office supplies and, after licensing key autographic printing patents from Thomas Edison, became the world's largest manufacturer of mimeograph equipment (Albert Dick coined the word "mimeograph").

A lithium polymer battery, or more correctly, lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly, and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Highly conductive semisolid polymers form this electrolyte.
With the return of the home video game market in the mid-1980s and the relative success of the Etch A Sketch Animator, Ohio Art decided to release a high-tech sequel to the Animator, known as the Animator 2000. Ohio Art released the system in 1987, at a suggested retail price of US$139.99 (equivalent to $380 in 2023).
Etching is used in microfabrication to chemically remove layers from the surface of a wafer during manufacturing. Etching is a critically important process module in ...
An example of Electron beam lithograph setup. Electron-beam lithography (often abbreviated as e-beam lithography or EBL) is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a resist (exposing). [1]
ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the speed of the etching process. The etching process is known as biting (see also spit ...
Reactive-ion etching (RIE) is an etching technology used in microfabrication. RIE is a type of dry etching which has different characteristics than wet etching . RIE uses chemically reactive plasma to remove material deposited on wafers .
Electroetching is a metal etching process [1] that involves the use of a solution of an electrolyte, an anode, and a cathode. The metal piece to be etched is connected to the positive pole of a source of direct electric current. A piece of the same metal is connected to the negative pole of the direct current source and is called the cathode. [2]
