A rotary boring bit consisting of two to four-cone-shaped, toothed rollers which are turned by the rotation of the drill rods. They are used in hard rock in oil well boring and other deep holes down to 15, 000 feet and more. Although their penetration speed is somewhat slow, roller bits last longer which is a very important factor in deep drilling.  2, record 2, English, - roller%20bit

The plasma centrifuge is one of [the] plasma isotope separation methods which relies on mass-dependent radial ion transport in a rotating plasma under strong centrifugal force. To improve the isotope separation factor, it is primarily important to confine the rotating plasma in a magnetic field for longer than the column rotation period [while] keeping ion temperature low.  2, record 3, English, - rotating%20plasma

On the left, a standard measure of gyro sensitivity is used : the factor by which the Earth rotation effect is greater than that from quantum(photon) noise over one hour. This is a big factor(the graph is coloured relatively "hot"), and on that basis the results we obtained at Cashmere from the C-II gyro indicate that on this criterion it is more sensitive than all others, such a reported atomic gyros. Note that the perimeter is important, and the mirror finesse also, though less so.  3, record 4, English, - gyro%26rsquo%3Bs%20perimeter

A gyro’s accuracy and performance can be judged by its output errors; for rate sensors the most important are: bias; scale factor error; noise...

Les erreurs de mesure des gyromètres laser peuvent être représentées par des modèles mathématiques beaucoup plus simples que ceux intervenant dans l'étude des gyromètres classiques. Cela résulte essentiellement de l'insensibilité des gyromètres laser aux accélérations. La description de l'erreur d'un gyromètre laser fait intervenir : a) une erreur de zéro [...] b) une erreur imputable au blocage [...] c) une erreur de facteur d'échelle, beaucoup plus faible que dans le cas des gyromètres mécaniques, due à une stabilité imparfaite des propriétés physiques des éléments de l'appareil.  1, record 5, French, - erreur%20de%20facteur%20d%27%C3%A9chelle

... for a mechanically dithered RLG [ring laser gyro], non-linearities(sidebands) appear in the input-output scale factor curve for an input rotation rate which is a harmonic of the dither frequency... There are two disadvantages to dithering. One is that the rotation rate periodically passes through zero where lock-in occurs. This results in a "random walk" angular position error. The other is that the vibration of the gyro body may affect other components or the gyro may be affected by other vibration sources. The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices.  1, record 6, English, - mechanically%20dithered

Mode pulling or scale factor effects are caused by changes in the index of refraction of the laser medium by dispersion effects of the laser gas.

Interactions laser-plasma dans le domaine relativiste [...] le comportement relativiste des électrons du plasma peut provoquer un phénomène très appréciable, car il permet d'accroître considérablement l'éclairement au foyer du laser; il s'agit de l'autofocalisation relativiste. Ce phénomène s'accompagne également du guidage du faisceau laser dans le plasma. L'autofocalisation du laser résulte d'une modification locale de l'indice de réfraction du milieu, induite par une augmentation de la masse des électrons libres du plasma. Dans ces conditions, le plasma se comporte comme une lentille convergente additionnelle qui s'oppose à la divergence naturelle du faisceau et produit une succession de «super foyers» où l'éclairement laser est encore accru d'un ordre de grandeur.  1, record 8, French, - indice%20de%20r%C3%A9fraction%20du%20milieu
