To examine the reliability of thermocouple comparison in industry at high temperature, thermocouple comparison measurements were performed around 1324 °C in nine laboratories by using two Pt/Pd thermocouples and one type R thermocouple following calibration at Co-C eutectic point. It was found that the standard deviations of the emf values of the Pt/Pd-2 (one of the Pt/Pd thermocouples) and type R thermocouples among nine participating laboratories were 4.2 μV (0.2 °C) and 5.0 μV (0.4 °C), respectively. © 2011 SICE.

Synthesiology | Year: 2012

The methodology of synthesis has been studied by analyzing 70 papers published in the academic journal, Synthesiology, launched in 2008. As a result, it has been found that each technological field has its distinctive features, e.g. there are many break-through type syntheses in biotechnology and nanotechnology, and the strategic selection types are commonly observed in the metrology and measurement field. In addition, we have found a common synthetic method as a whole. A kind of methodology called "technological synthesis" has been found to be important in the Full Research, and continuous follow-up process called "synthesis for social introduction" is also found to be one of the features to introduce the research results to society. Both the former and the latter involve feedback processes, and moreover, in the latter case, a dynamic synthetic method that can be called a spiral-up process is observed, where many feedback processes are repeated successively through social trials.

Recently, the eutectic points are being studied by many national institutes, and considered being useful for the calibration laboratories in industry to improve their uncertainty of thermocouple calibration at high temperature. To conduct a cooperative research for investigation on the reliability of thermocouple calibration in industry at high temperature, a working group has been established within the Japan Society for the Promotion of Science (JSPS). AIST and nine domestic laboratories participated to this working group. In this working group, thermocouple comparison measurements were performed at around 1300 °C in nine laboratories by using two Pt/Pd thermocouples and one type R thermocouple following calibration at Co-C eutectic point. It was found that the uncertainties of calibration at around 1300°C in industry would be improved by utilizing the calibration at Co-C eutectic point. © 2013 AIP Publishing LLC. Source

Objective: Infrared thermography systems have been used for fever screening at many airports since the outbreak of severe acute respiratory syndrome (SARS) in 2003. However, many of these systems are expensive and non-portable. Therefore, we developed a cost-effective and compact (2.9 × 5.8 × 2.0. cm) thermopile array for fever screening of patients with infectious diseases in the clinical setting. Methods: The array was created with small pixels (48 × 47 = 2256 pixels) fabricated on a silicon wafer using microelectromechanical systems technology. We tested this array on 155 febrile and afebrile patients (35.4. °C ≤ axillary temperature ≤ 39.3. °C) with seasonal influenza at the Japan Self-Defense Forces Central Hospital. Results: The maximum facial temperature, measured by the array at 0.3 m from the subject, exhibited a positive correlation with axillary temperature measured using a contact-type thermometer (r = 0.71, p < 0.01). The sensitivity and specificity of the thermopile array in identifying the febrile subjects were 80.5% and 93.3%, respectively, setting the threshold cut-off of maximum facial temperature at an appropriate value. Conclusions: Our cost-effective thermopile array appears promising for future close-range fever screening of patients with infectious diseases at primary care doctor clinics, health care centers, and quarantine stations in developing and developed countries. © 2014 The Authors.
