    摘要： A radiation clinical thermometer has a probe with an optical guide and an infrared sensor, a detection signal processing section, a body temperature operating section, and a display unit. A filter correction system for setting a correction value based on the transmission wave length characteristics of a filter is also provided. The body temperature operating section receives infrared data, temperature sensitive data, which takes into account the temperature equilibrium between the optical guide and the infrared sensor, and a correction value from the filter correction section so as to calculate body temperature data.

    摘要： An optical measurement apparatus 10 primarily includes: a photon detection unit 12 for detecting incident photons, a time signal output unit 14 for outputting a time signal, and a storage unit 16 for storing the time signal outputted from the time signal output unit 14 when the photon detection unit 12 detects photons. The photon detection unit 12 includes a HPD 24 having a photocathode 24a and an APD 24b, a TZ amplifier 26, a peak holding circuit 28, and an A/D converter 30. The time signal output unit 14 includes a timer 32 and a counter 34. The storage unit 16 includes a comparator 36 and a memory 38. When photons impinge on the HPD 24, a trigger signal is outputted from the comparator 36, causing the photon-number outputted from the A/D converter 30 and the time data outputted from the counter 34 to be stored in the memory 38.

    摘要： Disclosed is an apparatus for analyzing fine particles such as blood cells in a fluid such as blood, the apparatus comprising a device for generating electrical signal pulses from the specimen particles which have passed a detecting section such as, for example, a flow pass. The signal pulses are compared with a predetermined threshold, and specific information concerning the specimen particles is detected for a period which is determined on the basis of the signals produced by delaying the signal pulses, from a moment at which the threshold value is exceeded by each signal pulse.

    摘要： The present invention provides a photodetection apparatus having such an arrangement that when signals from the light receiving means in the photodetection device are sampled at a frequency substantially equal to the lowest frequency at which the source of pulse rays is lighted on, one of the noise signal I.sub.nc due to the pulsed illumination as from the fluorescent lamp and the normal output signal I.sub.sc from the laser beam necessarily presents for each of the sampling periods. In the preferred forms, output signal values sampled in the number of cycles corresponding to at least three times the sampling period are compared with each other. If it is judged that one output signal is larger than the other two output signals which are substantially equal to each other, it is determined that the one output signal is a normal output signal I.sub.sc from the laser beam. The one output signal is then taken for the subsequent signal processing step. In the other case, all the output signals are determined to be noise signals from disturbance rays as from the fluorescent lamp, including AC components and will not be taken for the subsequent signal processing step. In such a manner, any adverse affection due to the pulsed AC rays can be eliminated.

    摘要： A process for spectroscopically measuring the content of a component in a liquid mixture involves passing a single optical beam through the mixture without the use of a reference beam and measuring the intensities of transmitted light in two different wavelength bands by means of two adjacent detectors responsive to light in the two wavelength bands respectively. The component being measured absorbs light within one of the wavelength bands. The ratio of the detector outputs can then be related to the component concentration. The principal use of the invention is for in-situ measurement of methanol in gasoline for motor vehicles.
