Abstract: Système de transmission de données numériques par fibres optiques, pouvant transmettre et reproduire avec précision des signaux de données numériques au niveau du récepteur (16) même lorsque le signal optique est atténué dans le support de transmission par fibres optiques (12). Un signal composite (24) est produit au niveau de l'émetteur (10) et représente la somme coïncidant dans le temps de l'amplitude non-zéro du signal numérique de données à transmettre et d'un signal variable dans le temps qui code au moins chaque amplitude non-zéro du signal numérique. Le signal composite (24) module un signal optique porteur qui est couplé à un support de transmission par fibres optiques (12) qui relie l'émetteur (10) au récepteur (16). Au niveau du récepteur (16), la présence de chaque signal variable dans le temps est détectée comme une amplitude non-zéro du signal numérique. Des organes (34) dans le récepteur (16) produisent une impulsion en réaction à la détection de chaque signal variable dans le temps pour reproduire le signal numérique transmis et pour détecter toute information (36) en plus de l'amplitude non-zéro du signal numérique qui a été codé dans le signal variable dans le temps.

Abstract: A low pressure process for making amorphous semiconductor alloy films (22) and devices at high deposition rates and high gas conversion efficiencies utilizes microwave energy to form a deposition plasma. The alloys exhibit high-quality electronic properties suitable for many applications including photovoltaic and electrophotographic applications. The microwave energy and reaction gases form a glow discharge plasma within a reaction vessel (12) to deposit an amorphous semiconductor film (22) from the reaction gases into a substrate (14). The reaction gases can include silane (SiH 4 ), silicon tetrafluoride (SiF 4 ), silane and silicon tetrafluoride, silane and germane (GeH 4 ), silicon tetrafluoride and germane, germane or germanium tetrafluoride (GeF 4 ). Hydrogen (H 2 ) can also be added to the reaction gases. Dopants, either p-type or n-type can also be added to the reaction gases to form p-type or n-type alloy films, respectively. Also, band gap increasing elements such as carbon or nitrogen can be added in the form of, for example, methane or ammoniagas to widen the band gap of the deposited alloys.

Abstract: The quality of toner fusing in an electrophotographic or xerographic copier or printer is improved by modifying the reference voltage employed, in conjunction with the fuser hot roll temperature sensing, with a factor correlated to the temperature sensed in the environment of the fuser assembly. In a typical embodiment, the environment temperature is used to develop the reference voltage applied for comparison with the signal from a direct hot roll temperature thermistor. Thus, the temperature set point toward which the hot roll is driven varies as a function of the environment temperature for the fuser assembly.

Abstract: A picture signal (PS1) occurring with picture information components at different signal levels in which the signal level differences are greater than the picture information differences at the signal levels is processed with the aid of an amplifier circuit (1-4) to a picture signal comprising picture information differences between a minimum and maximum value. To this end the amplifier circuit comprises two parallel signal channels (1,2) and (3,4) and a change-over circuit (2, 4, 5-16) via which one channel for signal processing is operative dependent on the picture signal level, whilst per channel, for example, a different gain factor (A or B) and a different bias (OV or -Vb) is present for a signal level shift. Change-over is effected by a voltage comparison circuit (5-10, 12-15) which is connected to the output of an amplifier (1) of the amplifier circuit (1-4) and compares the output voltage with a substantially constant direct voltage

Inventor: SPRAGUE ROBERT A
IPC: G02F1/315
Filed: 1986-12-16
Abstract: An optical image bar (12) utilizing polarized light and a coherent spatial light modulator (16) includes birefrigent spatial or angular shearing means (51) for uniformly dividing the spatially-modulated output radiation of a coherent image bar into a pair of laterally-offset, redundantly-modulated, orthogonally-polarized optical field distributions. Imaging optics (17), which include any spatial filtering and/or polarization filtering elements needed for converting those field distributions into correspondingly-modulated spatial intensity distributions, bring the filtered field distributions to focus on an output image plane (13), thereby producing redundantly-modulated, laterally-offset, intensity profiles on the output image plane which spatially sum with each other on an intensity basis. The magnitude of the shear is selected so that the image plane offset of those intensity profiles is approximately equal to half the nominal image plane pixel pitch of the image bar, whereby each of the intensity profiles redundantly overwrites the interpixel intensity nulls of the other. Spatial shearing is preferred for image bars having telecentric imaging optics, but angular shearing is a practical alternative for some embodiments.

Title: Method and system employing double-acting, fluid-driven, twister-pairs as combined joints and motors in robots
Inventor: PAYNTER HENRY M
IPC: B25J17/02
Filed: 1987-02-11
Abstract: The method and system employ double-acting, fluid-­driven, twistor-pairs (30) as combined joints and motors in the arms and legs of robots. Thus, the twistor-pair at each joint (20) advantageously serves as the hinge or flexural support for the limb (40) carried (supported) by the joint and simultaneously serves as the double-acting turning motor for moving the limb portion of the arm or leg which is supported by the twistor pair. By controllably varying the fluid pressures P₁ and P₂ (usually pressurized air) being fed into the two elastic shells (33) which form the respective fluid chambers of the double-acting, twistor-pair located at each joint, the joint becomes deflected into predetermined predictable angular positions, depending upon the fluid pressure values. Costly and friction-­producing bearings are eliminated at the robot joints, and by virtue of eliminating such rotary bearing mountings at all desired joints not only are mass, weight and inertia substantially reduced, but also frictional effects and the torque drags caused by friction­al effects are nearly eliminated. By virtue of the fact that the deflection of the joint into different angular positions is a predictable and predetermined linear function of the two fluid pressures P₁ and P₂ fed into the interiors of the two shells of the twistor-pair at each joint, an advantageous uncomplicated, low cost open loop control method and system can be employed to operate these robots. Programmed motion of each jointed arm or jointed leg is produced by the convenient method of transmitting two control­lably variable fluid pressures P₁ and P₂ from a modulated supply through a pair of feed lines (42,44) in each arm or leg, thus achieving open loop dispatch control for many different industrial appli­cations.
