  2. Thin shrink small outline package - Wikipedia

    en.wikipedia.org/wiki/Thin_Shrink_Small_Outline...

    The Thin shrink small outline package has a smaller body and smaller lead pitch than the standard SOIC package. It is also smaller and thinner than a TSOP with the same lead count. Body widths are 3.0 mm, 4.4 mm and 6.1 mm. The lead counts range from 8 to 80 pins. The lead pitches are 0.5 or 0.65 mm.

  3. Cold shrink tubing - Wikipedia

    en.wikipedia.org/wiki/Cold_shrink_tubing

    The following video demonstrates the installation process of using Cold Shrink to abandon power cables. Cold shrink tubing is used to insulate wires, connections, joints and terminals in electrical work. It can also be used to repair wires, bundle wires together, and to protect wires or small parts from minor abrasion. It needs storage in ...

  4. Quarter-wave impedance transformer - Wikipedia

    en.wikipedia.org/wiki/Quarter-wave_impedance...

    Inverters are classified as K-inverters or J-inverters [5] depending on whether they are inverting a series impedance or a shunt admittance. [1] Filters incorporating λ/4 inverters are only suitable for narrow band applications. This is because the impedance transformer line only has the correct electrical length of λ/4 at one specific frequency.

  5. Quart - Wikipedia

    en.wikipedia.org/wiki/Quart

    The Winchester quart is an archaic measure, [10] roughly equal to 2 imperial quarts or 2.25 liters. The 2.5 L bottles in which laboratory chemicals are supplied are sometimes referred to as Winchester quart bottles , although they contain slightly more than a traditional Winchester quart.

  6. Induction shrink fitting - Wikipedia

    en.wikipedia.org/wiki/Induction_shrink_fitting

    Induction heating is a non contact heating process which uses the principle of electromagnetism induction to produce heat in a work-piece. In this case thermal expansion is used in a mechanical application to fit parts over one another, e.g. a bushing can be fitted over a shaft by making its inner diameter slightly smaller than the diameter of the shaft, then heating it until it fits over the ...

  7. Shrink-fitting - Wikipedia

    en.wikipedia.org/wiki/Shrink-fitting

    Shrink-fitting is a technique in which an interference fit is achieved by a relative size change after assembly. This is usually achieved by heating or cooling one component before assembly and allowing it to return to the ambient temperature after assembly, employing the phenomenon of thermal expansion to make a joint.

  8. Shrink wrap - Wikipedia

    en.wikipedia.org/wiki/Shrink_wrap

    Shrink wrap, also shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. [1] [2] [3] Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.

  9. Length contraction - Wikipedia

    en.wikipedia.org/wiki/Length_contraction

    [5] For mathematical consistency, Lorentz proposed a new time variable, the "local time", called that because it depended on the position of a moving body, following the relation t ′ = t − vx/c 2. [8] Lorentz considered local time not to be "real"; rather, it represented an ad hoc change of variable. [9]: 51, 80
