Abstract: A method for the fabrication of gallium arsenide (GaAs) metal-semiconductor field effect transistor (MESFET) is described. The method requires the step of providing a semi-insulating GaAs substrate (10) having thereon a layer of n doped GaAs (24) and another layer of n+ doped Ga 1-x Al x As (not shown), the latter being used as a diffusion source for n dopants in selectively doping the n GaAs layer underneath to form source and drain regions (22. 24). The fabrication method further includes the step of employing highly directional reactive ion etching on silicon nitride to build insulating side walls 18, 20 to effect the self-alignment of the gate of the MESFET with respect to its source and drain.

Abstract: A system for detecting vibrations occurring at the internals of a reactor pressure vessel is so designed as to enable maintenance of a vibration detector located in a housing (1) from outside the reactor pressure vessel (13). For this purpose, a guide tube (10) has one end fed through a nozzle or pipe stub (11) to a conical or cylindrical receptacle (8) connected to the core internals (9). An end (12) of the guide tube (10) remote from the pressure vessel (13) is cup-shaped and is sealed with a cover (6). A flexible rod (5) is connected to the housing (1) and its other end extends into the cup-shaped end (12) of the guide tube (10). The flexible rod (5) - and with it the housing (1) - can be inserted into the receptacle (8). Tight contact between housing 1 and receptacle 8 provides good transmission of the vibrations at the internals (9), which reach an evaluation unit (not shown) through cable (3). <IMAGE>

Abstract: A gripper constituted by two discs hinged to each other in order to rotate in parallel planes, each disc being provided with a handle arm, one of said discs being provided on its periphery with two teeth orthogonal to the plane of rotation and separated by a slot, and the other of said discs being provided on its periphery with a tooth which is also orthogonal to the plane of rotation and is configured as an arcuate hook pointing outwards; a tooth is hinged to the first arm so that it can be made to withdraw from and approach the two teeth of said arm. The loop of an iron wire wound about the end of a flexible hose is hooked on to the hook, while the ends of the wire are passed through the slot and through the space between the mobile tooth and the tooth adjacent to it. The wire ends are held rigid by moving the mobile tooth against them, and the gripper is then rotated by means of its two arms in order to move the hook away from the point at which the wire ends are held rigid, so tightening the wire about the hose and producing a properly tightened clamp.

Abstract: A component 2 to be identified is placed on a rotating turntable 1. An electronic line scan camera 4 is directed onto turntable 1 and scans along radial lines to obtain a digitised video signal having a multiplicity of levels. The lighting contrast may be enhanced by suitably positioned lighting 3. Points on each radial line at a predetermined radius are selected to generate an identification signal for the component which is compared with a database of such signals held in a store. When a match is obtained the component is identified. There may be a relatively coarse initial scan covering a full 360° rotation and finally the turntable can be positioned to orientate component 2 at a required position to enable it to be picked up by an arm 8 of a robot 7.

Abstract: L'invention concerne un volet d'insertion destiné au guidage des lettres durant leur insertion dans les cases d'un tambour tournant. Il s'agit d'injecter axialement dans une case d'un tambour tournant, à vitesse angulaire Ω, une lettre arrivant à la vitresse v. Pour cela, un volet prend en charge la lettre à l'interface entre le système de convoyage et le tambour, le volet pivote dans le sens de rotation du tambour à la même vitesse angulaire que lui et accompagne ainsi la lettre en augmentant le temps disponible d'insertion avant de revenir brusquement à sa position initiale pour recommencer un nouveau cycle ; ceci permet de compenser les fluctuations rapides de vitesse du tambour et du banc tandis qu'un calcul de l'instant de départ de chaque lettre permet de compenser les fluctuations lentes de vitesse du tambour et du banc. L'invention trouve son application dans tous les équipements de tri postal où se recontre un interface entre un système de courroies d'acheminement des lettres et un système de cases de réception en forme de tambour tournant.

Abstract: A switch mechanism is described in which a first contact carrier (12) having a first contact member (15), is movable between an inoperative position (Figure 1) and an operative position (Figure 3). A latch mechanism (16, 25) retains the first contact carrier (12) in the operative position (Figure 3) when moved thereto but a spring (14) urges the first contact carrier (12) towards the inoperative position. A second contact carrier (17) having a second contact member (23) and movable between first and second positions is biased by a spring (18) towards the first position (Figure 1) where the first contact carrier (12) engages an abutment (21) on the second carrier (17). Movement of the second carrier (17) towards the second (lower) position causes the first carrier (12) to be moved into its operative position and the subsequent return of the second carrier (17) towards the first position is accompanied by the engagement of the first and second contact members (15, 23).

Abstract: Proportioners may be used in hydraulic circuits to provide the symmetrical deployment of components controlled by these circuits. In the airbrake-deploying circuit of an aircraft, for example, certain fail-safe conditions must be satisfied i.e. the symmetrical deployment of the airbraking surfaces, and therefore the inclusion of a proportioner is desirable if not essential. The invention described herein relates to a proportioner having twin fluid flow path which incorporates a stepper motor, the stepper motor being operable to adjust the flow in each flow path via throttling means so that the airbrakes, for example, are deployed synchronously. The proportioner is also inherently fail-safe, as the pressure differential in the two fluid flow path acts to cancel any imbalance which may be present in the hydraulic circuit should the stepper motor fail.
