Abstract: A strain detecting device includes a sensor portion and an elastic deformation member covering the sensor portion. The elastic deformation member generates heat when it is compressed and absorbs heat when it is expanded. The sensor portion includes a first and a second heat flux sensors, each of which has a first sensor surface and a second sensor surface formed on sides opposite to each other. Each of the sensors outputs a sensor signal having a positive polarity when the heat flux passes through the sensor in a direction from the first sensor surface to the second sensor surface or outputs a sensor signal having a negative polarity when the heat flux passes through the sensor in the reversed direction. A heat absorbing member is interposed between the first and the second heat flux sensors. The first sensor surfaces of the respective heat flux sensors are opposed to each other across the heat absorbing member. The sensor portion generates the sensor signal depending on the heat flux generated by deformation of the elastic deformation member.

Abstract: A failure diagnostic apparatus for use in a ball screw conveyer includes a bearing stopper placed in contact with a bearing supporting a ball screw, a sensor unit equipped with an elastic member and a heat flux sensor, and a malfunction detector. The heat flux sensor works to produce an output as a function of deformation or displacement of the bearing stopper. The malfunction detector works to analyze the output from the heat flux sensor to detect a failure in operation of the ball screw conveyer. This enables a malfunction of the ball screw conveyer to be detected quickly and accurately.

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 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.

Abstract: In a runout detection device for detecting runout of a rotating member, a displacement unit abuts on the rotating member, and is displaced in accordance with displacement of the rotating member while the rotor abuts on the displacement unit. An elastic member elastically deforms in accordance with displacement of the displacement unit. A heat flux sensor detects a heat flux generated by elastic deformation of the elastic member. The runout detection device is configured to detect runout of the rotating member based on the heat flux detected by the heat flux sensor.

Abstract: A load change detection apparatus is provided with a base member, an elastic member, a first plate, a fixing member and heat flow sensors. The elastic member deforms according to a changed load applied to the elastic member, received by the receiving member. The first plate supports a surface of the elastic member on a side of the base member. The fixing member fixes the lower plate and the elastic member to the base member. The heat flow sensors, provided between the base member and the lower plate, output signals according to heat flowing between the lower plate and the base member. The heat flows due to heat generated or heat absorbed when the elastic member changes the elasticity shape thereof. Stress occurring when the elastic member deforms, is shut off by the first plate, thus direct transmission of the stress to the heat flow sensors is avoided.
