    Abstract: The invention relates to a method and apparatus for temperature compensation in gas analyzer equipment for transient error caused by temperature change. According to the method, a radiation source (1) is used for transmitting electromagnetic radiation through a gas mixture to be analyzed, the intensity of radiation transmitted through the gas mixture being analyzed is detected by means of a thermal detector (4) comprising a radiation detecting sensor element (16) and a reference sensor element (17) for generating an output signal proportional to the concentration of gas being analyzed, the temperature of said thermal detector (4) is measured either directly or indirectly, the measured detector temperature values are recorded as a function of time, and the output signal of the thermal detector (4) is temperature compensated by a correction term dependent on the temperature rate of change (DT) of the thermal detector. According to the invention, the uncorrected output signal V.sub.mass of the thermal detector (4) is temperature compensated by adding a correction term V.sub.comp dependent on the temperature rate of change (DT) of the thermal detector to said output signal.

    Abstract: A colorimeter for characterizing the color of an object is placed in an environmentally sealed enclosure for use in industrial environments. In order to maintain an acceptable operating temperature for the colorimeter's electronics and lamp, a heat shield is placed around the lamp to substantially isolate it from the electronics. The heat shield and the environmentally sealed enclosure are made of a highly heat conductive material such as aluminum. The heat shield is thermally coupled to the environmentally sealed enclosure.

    Abstract: An apparatus for measuring amylose and/or amylopectin content in rice. A near infrared light beam having its wavelength in a range of from about 1900 nm to about 2500 nm is applied to sample rice (5). A detector (26, 27,28) receives light reflected from and/or transmitted through the sample rice (5), to generate signals representative of luminous intensity of the received light. A memory device (122) has stored therein content conversion coefficients set for the amylose and/or amylopectin. A calculation device (123) calculates the amylose and/or amylopectin content in the sample rice (5), based on the detecting signals from the detector (26,27,28) and the content conversion coefficients stored in the memory device (122). The calculated content is displayed by a display device (126,127).
