    Abstract: 本发明涉及一种散射光探测器,主要用于探测载体介质内的粒子,它包括外壳(1)、外壳(1)上的进口(3)和出口(5),载体介质在进口和出口之间沿流动路径(7)流过外壳(1),还包括光源(9),它将光对准位于流动路径(7)上的散射光中心(11),还包括用于一部分散射在散射光中心(11)内的粒子上的光的接收器(13)、以及用于未散射在散射光中心(11)内的光的光阱(15)。本发明的目的是改进这种散射光探测器,以保证结构紧凑,但仍然有高灵敏度。为此,光阱(15)采用两种设计方案。按第一种方案,光源(9)设在流动路径(7)之外,光源(9)光锥(20)的中轴线(18)至少部分平行于流动路径(7)中心线(58)或在此中心线(58)上延伸,以及,光源(9)配设的光阱(15)是导引流动路径(7)的流动通道的一部分。按第二种方案规定,接收器(13)设在流动路径(7)之外,接收器轴线(14)至少部分平行于流动路径(7)的中心线(58)或在此中心线(58)上延伸,以及,接收器(13)配设的光阱(23)是导引流动路径(7)的流动通道的一部分。

    Abstract: An oil mist detector is provided to judge that the transparent window is contaminated based on the comparison result so that the contamination of the transparent window is detected accurately by comparing a contamination error value with a detection signal value generated from a light receiving device. An oil mist detector(1) comprises a casing(6) having an oil mist introduction chamber arranged in a crankcase of an internal combustion engine. A light emitting device and a light receiving device so arranged as to face an outer side of a transparent window provided in the oil mist introduction chamber. The light emitting device emits light to a predetermined detection region in the oil mist introduction chamber through the transparent window, and the light receiving device receives through the transparent window scattering light generated from the irradiated light hitting oil mist present in the detection region, thereby achieving oil mist detection. A zero point shifting structure is provided which makes a given amount of background scattering light from the casing incident on the light receiving device under absence of oil mist in the oil mist introduction chamber. A control device(12) receives a detection signal from the light emitting device. The control device has a contamination error judging part for comparing a contamination error value with a detection signal value, and judges that the transparent window is contaminated when the detection signal value exceeds the contamination error value.

    Abstract: A diagnostic analyzer includes a track, a light-blocking member, a motor, and an optical testing device. The track moves a reaction vessel held by the track. The light-blocking member is disposed adjacent to the track. The light-blocking member moves from a first position apart from the track to a second position closer to the track. When the light-blocking member is disposed in the first position a sample contained within the reaction vessel held by the track is exposed to light. When the light-blocking member is disposed in the second position the sample contained within the reaction vessel held by the track is blocked from exposure to the light. The motor moves the light-blocking member between the first and the second positions. The optical testing device is disposed adjacent to the track for optically testing the sample contained within the reaction vessel held by the track when the at least one light-blocking member is disposed in the second position.
