  • Patent number: 11067519
    Abstract: A strain detecting device includes a sensor portion and a covering elastic deformation member. The elastic deformation member generates heat when compressed and absorbs heat when expanded, resulting in heat flux. The sensor portion includes first and second heat flux sensors, each of which has first and second sensor surfaces formed opposite to each other. Each sensor outputs a strain-indicating signal of a polarity when the heat flux passes through the sensor, from the first sensor surface to the second sensor surface, and outputs a strain-indicating signal of an opposite polarity when the heat flux passes through the sensor in reverse, from the second sensor surface to the first sensor surface. The first sensor surfaces are opposed to each other across a heat absorbing member interposed between the sensors. The sensor portion generates signals based on the heat flux generated by deformation of the elastic deformation member.

  • Patent number: 11029269
    Abstract: A support device comprises a piston rod and a fixed member arranged so that a target object is placed therebetween, and an elastic member is provided to the target object side of the fixed member. A monitoring device includes a heat flux sensor and a detection part. When the target object is supported between the piston rod and the fixed member due to force applied by the piston rod, the heat flux sensor outputs a signal corresponding to the heat flux flowing between the elastic member, which is compressed by the load applied from the piston rod, and the fixed member. Based on the signal output by the heat flux sensor, the detection part detects the support state of the target object supported by the support device, or the size of the target object.

  • Patent number: 10982973
    Abstract: A position change measuring device which measures a change in position of a target object and includes a base member, a press member which is movable following a change in position of the target object, an elastic member which produces heat when contracting or absorbs heat when expanding, a heat flux sensor which outputs a signal as a function of a rate of heat flux transferred inside or outside the elastic member, and a diaphragm unit which is made of elastically deformable material. The diaphragm unit is retained by the base member in contact with the press member and works to produce force of resilience to recover the elastic member to its initial state when the elastic member contracts or expands in response to movement of the press member. This structure improves a response rate for sensing a change in position of the target object with high accuracy.

  • Patent number: 10845256
    Abstract: A diagnosis apparatus diagnoses an assembly state of an assembled component having a sliding portion. The diagnosis apparatus includes a sensor unit that detects a heat flux flowing from the sliding portion toward an outside, and a control apparatus that determines whether an assembly state of the assembled component is correct or not based on a detection result detected by the sensor unit. A magnitude of a heat flux from the sliding portion is different between when the assembly state of the assembled component having the sliding portion is correct and when it is incorrect. Hence, according to the diagnosis apparatus, it is possible to diagnose whether an assembly state of the assembled component is correct or not.
