Record 1 2014-01-29

English

Subject field(s)
  • Atomic Physics
DEF

A nanoscale assembly of self-pivoting molecules capable of transmitting a rotational movement.

CONT

Manufacturing nano-objects. Nanogears. This computer simulation shows a gear system made from a carbon nanotube 1 to 10 nanometres in diameter. Molecules of benzyne(the teeth) are attached to carbon nanotubes(the shafts) to form tough, efficient mechanisms. Such systems could be operated using lasers or electrical fields. Recently, several teams have managed to attach atoms and molecules to nanotubes, opening up a promising line of research.

Key term(s)
  • nano-scale gear
  • nano-gear

French

Domaine(s)
  • Physique atomique
DEF

Assemblage de molécules à l'échelle nanométrique qui, lorsqu'elles pivotent sur elles-mêmes, transmettent un mouvement de rotation.

CONT

Alors comment fait-on pour construire des nanomachines? Avec un rayon laser qui attrape les molécules les unes après les autres, ou à l'aide d'un microscope à effet tunnel, on a déjà créé des nanotubes, et on doit arriver à faire des nano-engrenages ou des nano-roulements à billes qui marchent à la lumière, c'est-à-dire qui fonctionnent avec peu d'énergie [...]

OBS

nano-roulement à billes : terme habituellement utilisé au pluriel.

Spanish

Campo(s) temático(s)
  • Física atómica
CONT

Futuro nanoengranaje construido con moléculas. Este dispositivo molecular será la pieza fundamental para el diseño de máquinas microscópicas y nanoscópicas que podrán viajar en cualquier medio, incluyendo el cuerpo humano, donde efectuará tareas de exploración, reparación y destrucción de anomalías que para el ojo humano pasarían imperceptibles. El diseño y desarrollo de los nanoengranajes, piezas fundamentales de las futuras nanomáquinas, están inspirados en las máquinas moleculares naturales que rigen la vida de cualquier organismo terrestre, como son las proteínas, las enzimas y las hormonas.

Record 3 1987-04-30

English

Subject field(s)
  • Landing Gear (Aeroindustry)
CONT

Landing gear visual indicators provide the flight crew with definite reference markings that can be physically checked to ascertain the position of the landing gear overcenter links while the airplane is airborne.... The main gear downlock visual indicators... are two red anodize stripes applied to each main gear downlock hinge.... The nosegear downlock visual indicators... consists of red anodize stripe applied to the upper and lower lock link assemblies at the breakover hinge point. When the nosegear is down and locked, a straight red anodize stripe is visible on the top side of the overcenter link when viewed through the peephole in flight compartment floor. When the nosegear is up and locked, a straight line of scotchlite tape is visible on the right side of the overcenter linkage extending across both upper and lower links, when viewed through the peephole in the flight compartment floor.

Key term(s)
  • downlock stripe
  • visual indicator stripe

French

Domaine(s)
  • Atterrisseur (Constructions aéronautiques)
OBS

repère visuel de verrouillage du train d'atterrissage : terme accepté par le Comité d'étude de la terminologie des cartes de travail du DC-9.
