Abstract: A strain detector is interposed between a base and an attachment member in a structure body having the base, the attachment member, and the stainless bolts fixed the base to the attachment member. The strain detector includes an elastic member and a heat flux sensor. The elastic member is provided to compress or extend in accordance with a deformation of the stainless bolts, and the elastic member generates heat based on the compression and absorbs heat based on the extension. The heat flux sensor is deformed in accordance with the compression or the extension of the elastic member and the heat in the elastic member is transferred to the heat flux sensor. The heat flux sensor can detect a magnitude of the heat flux Fh1 as a heat stream between the inside of the elastic member and the outside, generated by the compression or the extension of the elastic member.

Abstract: A monitoring device monitors a forming machine (target device). The forming machine includes a housing, a bearing attached to the housing, and a shaft placed radially inside the bearing. The monitoring device includes a plurality of heat flux sensors and a detector. The heat flux sensors are provided on the radially outer side of the bearing and spaced from each other in the circumferential direction of the bearing. The heat flux sensors output a signal corresponding to heat fluxes through faces thereof on the bearing side and faces thereof on the other side. The detector detects a load applied radially to the shaft or bearing, based on the output from the heat flux sensors.

Abstract: A wind direction meter has the following plurality of sensors and a control unit. Each sensor has a first surface and has first and second interlayer connection members made of different metals or semiconductors. Further, the wind direction meter includes a thermoelectric conversion element which generates an electrical output when a temperature difference occurs between first ends and second ends of the respective first and second interlayer connection members. The sensor generates an electric output when the surrounding air, whose temperature has been changed by a heater, is moved by the wind to produce a temperature difference between the first ends and the second ends of the first and second interlayer connection members. The control unit calculates the direction of the wind on the basis of the difference in output. Thus, the wind direction of a weak wind can be detected with the wind direction meter.

Abstract: A heat flux sensor is installed in such a way that heat flux emanating from a biological object present at a predetermined position is detectable. It is determined whether or not a biological object is present at the predetermined position by comparing sensing results of the heat flux sensor with determination criteria. The determination criteria is preset according to heat flux that can be sensed when a biological object is present at the predetermined position. When the sensing results of the heat flux sensor satisfy the determination criteria, in other words, when the heat flux sensed by the heat flux sensor is the heat flux emanating from a biological object, it is determined that a biological object is present at the predetermined position. Consequently, it is possible to realize accurate detection of a biological object.
