Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners, laser printers, and photocopiers, but for many years they were the primary means of reproducing documents for limited-run distribution.
A mimeograph machine (often abbreviated to mimeo, sometimes called a stencil duplicator or stencil machine) was a low-cost duplicating machine that worked by forcing ink through a stencil onto paper. [1] The process was called mimeography, and a copy made by the process was a mimeograph.
He (i) atomizes the conventional register "address:datum" into its two parts: "address", and "datum", and (ii) generates the "address" in a specific register n to which the finite-state machine instructions (i.e. the "machine code") would have access, and (iii) provides an "accumulator" register z where all arithmetic operations are to occur.
The square kilometre (square kilometer in American spelling; symbol: km 2) is a multiple of the square metre, the SI unit of area or surface area. In the SI unit of area (m 2), 1 km 2 is equal to 1M(m 2). 1 km 2 is equal to: 1,000,000 square metres (m 2) 100 hectares (ha) It is also approximately equal to: 0.3861 square miles [2] 247.1 acres [3 ...
A contact copier (also known as contact printer) is a device used to copy an image by illuminating a film negative with the image in direct contact with a photosensitive surface (film, paper, plate, etc.). The more common processes are negative, where clear areas in the original produce an opaque or hardened photosensitive surface, but positive ...
In post-Soviet states, the sign indicating the end of a one-way road has a crossed-out up arrow inside the square . However, Lithuania uses a different sign to mark the end of a one-way road, and is only used if a one-way road meets a two-way road at an intersection. The Lithuanian sign has an up arrow on the right and a down arrow on the left ...
Button copy is a type of physical design for road signs in the United States. Round plastic retroreflective buttons made of transparent plastic are placed in rows following the contours of sign legend elements, usually painted white, such as letters, numbers, arrows, and borders.
