Title: Transistor à effet de champ à fréquence de coupure élevée et son procédé de réalisation
Inventor: DELAGEBEAUDEUF DANIEL
IPC: H01L29/43
Filed: 1980-03-14
Abstract: L'invention concerne les dispositifs à fréquence de coupure élevée et plus particulièrement les transistors à effet de champ à hétérojonction à accumulation de porteurs majoritaires. Les transistors selon l'invention utilisent les propriétés des jonctions GaAs/AlxGa1-xAs de même type, dopées N, GaAs étant faiblement dopé, favorables à une grande mobilité des charges dans la couche d'accumulation : une structure selon laquelle les régions de source et de drain sont partiellement recouvertes par la région de grille, elle-même recouverte par une couche d'isolant, diminue les résistances d'accès et augmente les fréquences de transition. Application aux transistors hyperfréquences pour télécommunications et circuits intégrés.

Abstract: Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP by a hydromechanical section. The hydromechanical section includes a torque motor which may be activated to modify the fuel flow to the engine in response to a control signal produced by an electronic control section. The electronic control section senses a number of engine and ambient parameters and generates engine operating limits from these parameters. The limit corresponding to the lowest maximum engine speed is selected and referenced to actual engine speed for generating the control signal, thereby providing a closed loop engine speed control. At least one of the computed limits is an actual maximum engine speed for steady state engine operation and is used to recompute the engine scheduled speed so that the actual maximum engine speed is obtained at the maximum power level advance position; in this way power lever dead band is eliminated. The electronic control also modifies fuel flow to the engine for speed synchronization with another identically controlled engine.

Abstract: A holding furnace for molten metal comprises an inner vessel (32) formed of flat, rigid, heat-resistant panels (37, 40, 41). The panels are held in sealing engagement with one another at abutting edge surfaces (42A, 42B, 43) by the action of inwardly directed pressure applied to the panels by an integrally cast refractory outer vessel (34) through the intermediary of a resilient layer (33) of heat-resistant fibrous material. The pressure is applied as a result of the shrinking the casting compound undergoes during the setting. When the inner vessel (32) is being made, the panels (37, 40, 41 to which the resilient layer (33) has initially been applied, are held together by the action of a reduced pressure in the inner vessel (32) as the latter is positioned in a furnace casing (36) interiorly lined with a mineral wool insulation (35). The inner vessel (32) then is cast around with a refractory casting compound for forming the outer vessel (34).

Abstract: Tone control device having a construction for operating on an input signal and on the signal obtained by passing the input signal through both a filter and a gain-controlled circuit, the gain of the gain-controlled circuit being varied by a control voltage for exercising tone control. One filter is used in common for establishing both bands of boosting and cutting to facilitate IC circuit manufacture. In order to prevent the cut-off frequency from deviating between the boosting-and the cutting-modes, the discrimination between the modes is made on the basis of the control voltage on the basis of which discrimination the characteristics and the gain of the filter are changed-over.
