Tantalum nitride (TaN) is a chemical compound, a nitride of tantalum. There are multiple phases of compounds, stoichimetrically from Ta 2 N to Ta 3 N 5, including TaN. As a thin film TaN find use as a diffusion barrier and insulating layer between copper interconnects in the back end of line of computer chips. Tantalum nitrides are also used in ...
The original TI-30. The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976.While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
It was based on the SR16 design from Kinpo Electronics.. Power sources come from smaller solar cells than the 1994 TI-34, and CR2025 battery. Feature set was based on TI-36X II, but without unit conversions and constants, base calculations, boolean algebra, complex value functions (abs now only works in real numbers), integral calculation, engineering notation display modes, gradian angle mode ...
The Texas Land Survey System is often measured in Spanish Customary Units. The most important of these is the vara, which, while ambiguous in the past, was legally established to be exactly 33 + 1 ⁄ 3 inches (846.67 mm) long in June 1919. [2] The subdivision levels in Texas are as follows: [3]
Basic resolvers are two-pole resolvers, meaning that the angular information is the mechanical angle of the stator. These devices can deliver the absolute angle position.
The TI-85 is a graphing calculator made by Texas Instruments based on the Zilog Z80 microprocessor.Designed in 1992 as TI's second graphing calculator (the first was the TI-81), it was replaced by the TI-86, which has also been discontinued.
The TI-95, also called the TI-95 PROCALC, is a keystroke programmable calculator and was introduced in 1987 by Texas Instruments.It was rather large, measuring 3.7" by 8" by 1" and had a 16-character alphanumeric display for the main display, and a set of five 3-character displays for use as menu items.
