  • 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.

  • Publication number: 20190359032
    Abstract: A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

  • Patent number: 10261034
    Abstract: 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.

  • Patent number: 10243130
    Abstract: In a step of pressing a laminate, the laminate is first pressed while being heated to a temperature lower than a melting point of a thermoplastic resin so as to elastically deform the thermoplastic resin and apply a pressure in a direction perpendicular to a laminating direction to thereby allow first and second conductive pastes to tightly adhere to front and rear surface patterns. Next, the laminate is pressed while being heated to a temperature equal to or higher than the melting point of the thermoplastic resin so as to fluidize the thermoplastic resin while allowing the thermoplastic resin to flow out from the laminate and apply a pressure in the direction perpendicular to the laminating direction to thereby allow the first and second conductive pastes are solid-sintered.
