    Abstract: A scatter signal is produced from light scattered by a precipitate formed by a chemical reaction and non-specific scatter sources. A blanking signal is produced for a scatter signal from light scattered only by the non-specific scatter sources that contribute to the scatter signal, and the blanking signal is subtracted from the scatter signal to dynamically produce a signal indicative of the difference between the scatter signals to reduce the effects of non-specific scattering sources in determining the rate of change of the light scattered by the precipitate. One of the scatter signals may be stored and then combined with the other, or the signals may be measured simultaneously and then combined.

    Abstract: Il est destiné à la mesure d'une caractéristique donnée d'un milieu fluide et comprend au moins un ensemble comportant : un réactif approprié à ladite mesure et prévu pour interagir avec le milieu fluide, des moyens de support du réactif, une fibre optique (2) appelée fibre émettrice, prévue pour envoyer de la lumière en direction des moyens de support, et au moins une autre fibre optique (4) appelée fibre réceptrice, prévue pour récupérer au moins une partie d'une lumière issue des moyens de support lorsque ceux-ci reçoivent la lumière provenant de la fibre émettrice. Les moyens de support comprennent un élément poreux ou adsorbant (10) unique sur lequel est fixé le réactif et qui est placé en regard de la fibre émettrice et de chaque fibre réceptrice. Cet élément est en contact direct avec le milieu fluide lorsque le capteur y est plongé, et donc dépourvu de membrane de confinement.

    Abstract: In making contact opening on insulation film which is provided on layer containing aluminium by selective dry etching method using reactive gas, the reactive gas containing chlorine compound gas such as CCI 4 is used; and then, when the contact opening reaches the layer containing aluminium, the intensity of emission spectrum of aluminium increases rapidly, accordingly it becomes possible to detect end point of the dry etching on the insulation film by detecting the intention of the emission spectrum of aluminium.

    Abstract: An optical analyzer for determining an analyte in a fluid of interest such as a body fluid of interest satisfying the foregoing need and embodying the present invention may include a housing (12); combination optically transparent cuvette and lancet (16) mounted removably in the housing (12), the cuvette (17) may receive an optically transparent reagent test system for reacting with the body fluid to produce a change in at least one optical transmissive characteristic of the system indicative of the analyte; a cuvette carrier (14) mounted slidably in the housing and for removably receiving the cuvette (17); a spring actuator (40) mounted in the housing and connected to the cuvette carrier (14), the spring actuator may be compressed and released to advance the carrier and thereby advance the lancet (16) into engagement with a portion of a body to produce the body fluid, and the spring actuator (40) retract the lancet (16) within the housing (12) after the advancement; depth control apparatus (70, 72) for controlling the depth of penetration of the lancet into the body portion; an electro-optical system (34, 36, 38) mounted in the housing in optical engagement with the cuvette (17) and for passing a light beam through the cuvette and the reagent system and for receiving the light beam modified by the change in optical transmissive characteristic of the system and for transmitting computation signals indicative of the analyte to a computer (22); a computer mounted in the housing for receiving the computation signals and for comparing the computation signals against predetermined data to produce display signals indicative of the analyte; a display (24) mounted in the housing and for receiving the display signals and for providing a visible display indicative of the analyte; and control switches (26) mounted in the housing and connected to the computer (22) for controlling the operation of the computer (22).
