Abstract: An abnormality diagnosis apparatus includes a sensor unit configured to detect a heat flux which flows from a target apparatus toward outside, and a determining unit configured to determine an abnormality of the target apparatus. The sensor unit includes a first heat flux sensor, a second heat flux sensor, and a thermal buffer which is disposed between the first heat flux sensor and the second heat flux sensor and which has predetermined heat capacity. The first heat flux sensor outputs a first sensor signal in accordance with a heat flux which passes through the first heat flux sensor from the target apparatus side toward the thermal buffer side. The second heat flux sensor outputs a second sensor signal in accordance with a heat flux which passes through the second heat flux sensor from the thermal buffer side toward a side farther from the target apparatus. The determining unit determines whether or not there is an abnormality of the target apparatus on the basis of the first sensor signal and the second sensor signal.

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 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.

Abstract: A temperature adjustment control device includes a heat diffusion layer, a heat flux sensor, and a temperature changing body provided in this order from a surface making contact with a human body. The heat flux sensor is disposed on the temperature changing body and outputs a sensor signal corresponding to a heat flux. The heat diffusion layer is disposed opposite to the temperature changing body through the heat flux sensor. The heat flux sensor outputs the sensor signal corresponding to the heat flux passing through the heat flux sensor in a direction in which the heat diffusion layer, the heat flux sensor, and the temperature changing body are arranged. A control portion controls a start and a stop of the power supply to the temperature changing body based on the sensor signal outputted from the heat flux sensor.
