Title: High speed complementary field effect transistor logic circuits.
Inventor: VINAL ALBERT WATSON
IPC: H03K19/0948
Filed: 1990-04-10
Abstract: A high speed, high density, low power dissipation all parallel FET logic circuit includes a driving stage having a plurality of parallel FETs of a first conductivity type for receiving logic input signals and a load FET of second conductivity type connected to the common output of the driving stage. A complementary FET inverter including serially connected FETs of first and second conductivity type is connected to the common output and the load FET. According to the invention the voltage transfer function of the complementary inverter is skewed so that the product of the carrier mobility and the ratio of channel width to length of the inverter FET of the first conductivity type is made substantially greater than the product of the carrier mobility and the ratio of channel width to length of the inverter FET of the second conductivity type. By skewing the voltage transfer function of the complementary inverter the voltage lift-off interval is dramatically decreased, thereby improving the speed. AND and OR circuits and combined AND-OR circuits may be provided, having true and complement outputs. A multigate serial load transistor may further reduce power consumption.

Abstract: Il est décrit une pompe à injection de carburant pour moteurs à combustion interne, dans laquelle il est prévu, pour la commande du débit de carburant, un dispositif de régulation électrique (23) commandant un organe de réglage électrique (25) qui, de son côté, actionne l'élément (18) déterminant le débit d'injection du carburant. L'alimentation en carburant du volume moteur de la pompe s'effectue par l'intermédiaire d'un conduit d'alimentation en carburant (8), dans lequel est montée une soupape d'étranglement réglable (40). Celle-ci est actionnée suivant la position d'une pédale de gaz (32), mais elle commande toutefois une section de passage du conduit d'alimentation (8) toujours plus grande que celle correspondant à la quantité dosée de carburant traversant le dispositif de régulation (23). Une section minimale de passage est déterminée par un étranglement fixe (46). Ce dispositif permet de disposer d'un mode de fonctionnement de secours en cas de panne de la commande électrique du débit d'injection de carburant, sans que le dispositif de secours perturbe la quantité dosée de carburant traversant le dispositif de régulation. L'étranglement fixe (46) empêche notamment qu'un emballement du moteur se produise involontairement de la part du conducteur, en cas de panne du dispositif de régulation.

Date May 30, 1991.A tester for a communications (e.g. telephone) line pair comprising a pair of different valued resistors (R1 and R2) each connected in series with a diode (D1 and D2). The diode/resistor pairs are connected in parallel between connectors (A and B) such that one of the pair provides a path for a DC voltage of one polarity and the other of the pairs provides a path for a DC voltage of the other polarity. The device is connected to the ends of a spare pair of telephone wires at a remote distribution point. The spare pair is provided with it's exchange equipment termination and testing is carried out at the local exchange via the test access facility to check that the pair of wires is in working condition before sending installers out in site. The test procedure includes measuring the total resistance of the lines to determine whether the difference in resistance readings as determined are in accordance with the difference between the resistances (R1 and R2) in the device itself. If so, the lines are in working condition. If not, there is a fault and the lines cannot be used.

Abstract: For the protection of sleeper bolts 4 against corrosion, the plugs 2 for anchoring the sleeper bolts in the sleeper 1 are filled before track installation - usually already during manufacture - with a corrosion-protecting viscous filler material 3. The incompressibility of such filler materials 3, which have the characteristics of a high-viscosity liquid, can produce high forces in the plugs 2, acting perpendicularly to the sleeper axis, during sudden mechanical screwing-in of the sleeper bolts 4, which forces can split the sleeper. In order to prevent this, it is proposed to use as a corrosion protection agent filler materials 3 which are interspersed with cavities or pores. <IMAGE>

Abstract: A fluid filter assembly 10 comprises a heater 12 and a filter 14 in series fluid flow relationship. A means for bypassing a fluid around the heater 12 and the filter 14 is provided which comprises ducts 16 and 22 and a relief valve 20 interposed between them. 
     In normal operation the relief valve 20 is closed so all the fluid flows through the heater 12 and the filter 14. The fluid and any liquid impurities entrained therein are heated by the heater 12 prior to passing through the filter 14. 
     At low temperatures the heater 12 cannot normally provide sufficient heat to prevent solidification of the liquid impurities entrained within the fluid which block the filter 14. The relief valve 20 then opens to allow a proportion of fluid to flow through the bypass so a reduced amount of fluid flows through the heater 12 and the filter 14. The heater 12 heats the reduced flow of fluid therethrough to a temperature sufficiently high to melt the solidified liquid impurities blocking the filter 14.
