Invar

where [a.sub.m]--staff reading; [alpha]--equation of temperature dependency of staff invar strip of 2.93 m, which common expression is

Constructed by Coast Composites of Irvine, California, for use in fabricating the composite upper-wing skins of the Lockheed-Martin F-35 Joint Strike Fighter, the mandrel, also made of Invar alloy, is 8 ft (2.4 m) tall, 14 ft (4.2 m) wide, 43 fi (13.1 m) long, and weighs 55,400 lb (25,130 kg).

We eventually found out that the large presses were deforming the Invar tools.

The measuring campaign of levelling lines was performed using the Wild NA 3000 digital level enabling automatic registration of readings on the bar-coded invar staff.

He dubbed the material an Invar alloy-because the metals are invariant when heated, such that the length of a piece of Invar metal does not change as its temperature is increased, as do normal metals.

So Zeiss engineers have really gotten to the fundamentals with this machine, by developing a patented temperature-resistant frame fabricated with invar (a steel alloy).

And, since the CFM110 features an "Invar" Shadow Mask, the image is free of aperture grille lines.

The CIDO configuration consists of a wave-guide cavity IMPATT oscillator coupled to a high Q, high order mode cylindrical Invar cavity.

Scale's adhesive ba cking mounts to all common material types, including granite, ceramic, steel, aluminum, iron, and Invar.

The ceramics provide quality factors and temperature stability better than those of invar cavity resonators along with an integration capability approaching that of stripline resonators.

Optical cavity mirrors are supported on platforms at either end of the laser; the platforms are connected by an Invar (low coefficient of thermal expansion) alloy structure to minimize the effects of temperature variation.

Carpenter Invar 36 [R] alloy can be successfully welded using most standard arc-welding processes.

Table 1 shows a comparison of Invar, graphite fiber reinforced epoxy, and dielectric resonator filter characteristics.
