摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A heat flow distribution measurement device includes a sensor module having one multilayer substrate and a plurality of heat flow sensor portions arranged inside of the multilayer substrate. The multilayer substrate has one surface and another surface opposite to the one surface and includes a plurality of stacked insulating layers each formed of a thermoplastic resin. The heat flow sensor portions are each formed of thermoelectric conversion elements and are thermoelectrically independent. An arithmetic portion arithmetically determines a heat flow distribution based on an electromotive force generated in each of the heat flow sensor portions. The thermoelectric conversion elements are formed in the multilayer substrate and therefore manufactured by the same manufacturing process for manufacturing the multilayer substrate. This can minimize the performance difference between the individual thermoelectric conversion elements and allow the heat flow distribution to be measured with high precision.

摘要： A human machine interface is configured to select an information display destination from among a plurality of display areas. The HCU acquires a sight line direction of a driver based on an image of an in-vehicle camera. The HCU displays, upon detecting a hop-off action of the driver based on an output signal of an in-vehicle sensor in a situation in which an attention target event such as a puddle, a step, other vehicle or the like exists on a road surface near a door of a driver's seat, in the display area corresponding to the driver's sight line direction, text or an image practically indicating (a) a content of an attention target event or (b) how to deal with a situation.

摘要： An air cylinder includes a tubular cylinder and a piston which is moved by pressure of a fluid supplied to a chamber provided inside the cylinder. A monitoring device includes a heat flux sensor and a detection part. The heat flux sensor is provided to the cylinder and detects heat flux that flows between inside and outside of the cylinder due to compression or expansion of the fluid in the chamber caused in accordance with the movement of the piston. The detection part detects the moving state of the piston based on the output signal of the heat flux sensor.

摘要： An operating-status diagnostic apparatus includes a sensor unit and a control unit. The sensor unit detects heat fluxes flowing outward from a component of a facility. A control unit determines whether or not an operating status of the facility indicates that the component is in a warming-up complete state where warming-up of the component is completed based on a detection result of detection by the sensor unit.

摘要： 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.
