Abstract: L'invention concerne une méthode in vitro qui est particulièrement utile pour le diagnostic des maladies thromboemboliques, comme la thrombophilie héréditaire ou non héréditaire, et pour déterminer le risque de thrombose lié à la grossesse, à l'utilisation des anovulants, à la chirurgie, etc. La méthode est caractérisée par le fait que le système de coagulation présent dans un échantillon est activé entièrement ou partiellement, d'une manière connue en soi, par incubation avec de la protéine C activée; on détermine ensuite la vitesse de conversion du substrat comme la coagulation ou la conversion d'un substrat chromogène. La vitesse de conversion obtenue est comparée avec les valeurs obtenues pour des échantillons de plasma normaux. L'augmentation de la vitesse indique que la personne de qui provient l'échantillon peut être atteinte d'une maladie thromboembolique.

Abstract: A fuel pump body has a chamber with one wall formed by an external diaphragm having a stem connected thereto.  The fuel pump body is attached to the outside of a valve cover for a gasoline engine and the valve cover has a depression that forms an enclosure for the diaphragm.  The stem passes through an aperture in the valve cover and connects to a lever pivotally attached to the underside of the valve cover.  The lever engages the valve rocker arm of the engine and produces reciprocal  movement of the stem and diaphragm as the rocker arm moves. The reciprocal movement of the diaphragm alternately draws fuel into the chamber through the inlet and that expels fuel through the outlet.

Abstract: In a process and installation for removing solvent vapor from exhaust air sucked from a working space, the air is fed to at least two parallel activated carbon adsorbers. Each adsorber can be switched to and fro between a charging mode in which it adsorbs solvent vapors from the exhaust air flowing through the adsorber, and a regeneration mode in which it is separated from the flow of exhaust air and flushed with water vapor and desorbed. To save energy and to reduce environmental pollution, at the end of the regeneration period each adsorber has a drying phase in which exhaust air from the working space flows through the adsorber, the air thereafter being fed to an adsorber which is operating in the charging mode. In the periods in which an adsorber is operating in the charging mode, it firstly has an initial phase followed by a main phase wherein air flows from adsorbers which are in the main phase are returned directly into the working space while the air flow from an adsorber which is in the initial phase is kept separate from the first-mentioned air flows.

Abstract: In a belt transmission device for preventing a slip of a belt, the belt is wound between a crank pulley of an engine and an alternator pulley on an alternator shaft connected to an alternator as an auxiliary for making belt transmission.          The alternator pulley is attached to the alternator shaft through a one-way clutch for connecting the alternator pulley and the alternator shaft only at the time of increase in angular velocity of a crank shaft. A centrifugal clutch which becomes  in  its  connection  state  by  the  increase  in centrifugal force accompanied with rotation of the alternator shaft is arranged in parallel with the one-way clutch. When the angular velocity is small,  the centrifugal clutch is disconnected but only the one-way clutch is connected. when the  angular  velocity  becomes  larger  than  an  allowable frequency of the one-way clutch,  the centrifugal  clutch operates to block the function of the one-way clutch.

Abstract: Apparatus and accompany-ing methods for use therein for a Coriolis mass flow rate meter (5) which is substantially immune to noise, and more particularly, to such a meter that is substantially unaffected by noise that occurs at substantially any frequency differ-ent from a fundamental frequency at which the flow tube(s) (130, 130') in the meter vibrates. Specifically, the meter (5) relies on measuring mass flow rule by determining the phase difference that occurs be-tween real and imaginary compo-nents or the discrete fourier trans-form (DFT) or both the left and right velocity sensor waveforms evaluated at the fundamental fre-quency at which the flow tubes vi-brate. The fundamental frequency is located, during an initialization operation, by providing a power spectrum, determined through use of the DFT, of one of the sensor signals and then selecting that frequency at which the magnitude of the power spec-trum reaches a maximum value. In addition, the frequency at which both velocity sensor signals are sampled is readjusted in re-sponse to any change in the phase of one of the velocity sensor signals, as transformed using the DFT, in order to assure that the sampling frequency always remains substantially equal to a pre-defined integer multiple or the fundamental frequency. Further-more, the meter, through use of the numerical value of any such phase change, also provides a density indication which is also substantially immune to such noise.

Abstract: In a noise cancelling device including a first subtractor for producing a first difference signal as a noise cancelled signal by subtracting a first pseudo signal from an input signal having a main signal and a first noise signal superposed on the main signal and a first adaptive filter for processing a second noise signal correlated with the first noise signal into the first pseudo signal in accordance with filter coefficients thereof, a second subtractor subtracts a second pseudo signal from the first pseudo signal to produce a second difference signal. A second adaptive filter processes the second noise signal into the second pseudo signal in accordance with filter coefficients thereof. First and second power averaging circuits produce first and second power averages of the second difference signal and the first pseudo signal, respectively. A step size calculating circuit calculates, from the first and the second power averages, a step size used for renewing the filter coefficients of each adaptive filter in deciding a rate of convergence of each adaptive filter. The first adaptive filter renews the filter coefficients thereof into renewed filter coefficients in accordance with the second noise signal, the first difference signal, and the step size. The second adaptive filter renews the filter coefficients thereof into renewed filter coefficients in accordance with the second noise signal, the second difference signal, and the step size.

Title: Electrostatic discharge protection circuit
Inventor: WAGNER GLEN R
IPC: H01L27/04
Filed: 1994-08-16
Granted: 2003-10-28
Abstract: A device for protecting an integrated circuit (IC) against electrostatic discharge (ESD) includes a self-triggered silicon controlled rectifier (STSCR) coupled across the internal supply potentials (Vcc, Vss) of the integrated circuit.  The STSCR exhibits a snap-back in its current versus voltage characteristic which is triggered at a predetermined voltage during an ESD event.  As large voltages build up across the chip capacitance, the predetermined voltage of the SCR (30) is triggered at a potential which is sufficiently low to protect the internal junctions of the IC from destructive reverse breakdown.  The STSCR comprises a pnpn semiconductor structure which includes an n-well disposed in a p-substrate.  A first n+ region (62) and p-type region (64) are both disposed in the n-well (60).  The n+ and p-type regions are spaced apart and electrically connected to form the anode of the SCR.   The ESD protection device also includes diode clamps (26, 27) between the periphery and internal power supply lines, and a novel well resistor which provides a distributed resistance further protecting sensitive output buffer circuitry.
