Abstract: A liquid level detector includes: a detecting element having one surface and the other surface opposite to the one surface, the one surface being opposed to a liquid, while being parallel to a height direction of liquid level; a Peltier element provided on the other surface side of the detecting element; and a control unit performing a detection processing for a liquid level of the liquid. The Peltier element forms a heat flow passing through the detecting element from the other surface to the one surface, toward the liquid or a gas. The control unit calculates a liquid level on the basis of an output value of an electrical signal outputted according to the heat flow passing through the detecting element, and a relationship between an output value of the detecting element and a liquid level.

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: There is provided a heat flux sensor with first and second interlayer connection members composed of different metals from each other of which metal atoms maintain a predetermined crystal structure embedded in first and second via holes of a thermoplastic resin made insulating substrate, the first and the second interlayer connection members are connected in series alternately, and a control unit that performs abnormality determination of a heating element disposed in a vehicle. The heat flux sensor is provided to the heating element and outputs a sensor signal corresponding to heat flux between the heating element and an outside air, and the control unit determines based on the sensor signal that there is abnormality in the heating element when the heat flux between the heating element and the outside air is out of a predetermined range.

Abstract: A non-contact power supply control system includes: an electric transmission pad connected to a power source unit; a control unit controlling current supply to the electric transmission pad; a living body detecting means detecting a living body present around the electric transmission pad; a power receiving pad magnetically coupled to the electric transmission pad to excite power, when current is supplied from the power source unit to the electric transmission pad; and a power storage unit storing power excited by the power receiving pad. The living body detecting means are arranged on the road surface side, and the control unit, when determining that no living body is present around the electric transmission pad on the basis of a result from the living body detecting means, controls the power supply unit to supply power to the power storage unit.

Abstract: A heat quantity control device has a heat flux sensor arranged between first and second heating elements arranged adjacently to each other, and a control section for controlling a heat quantity of the first and second heating elements. The heat flux sensor has an insulation board made of thermoplastic resin, first and second via holes formed in the insulation board penetrating in a thickness direction thereof. First and second layer connection members are embedded in the first and second via holes, respectively. The first and second layer connection members are made of different metals and alternately connected in series. The control section controls a heat quantity generated in the first and second heating elements based on the electromotive force generated in the heat flux sensors so that a heat flux flowing between the first and second heating elements becomes not more than a predetermined value.

Abstract: An insulating substrate is prepared. In this substrate, plural via holes penetrating in a thickness direction are filled with a conductive paste. This paste is produced by adding an organic solvent to a powder of an, and by processing the power of the alloy to a paste. The substrate is then pressed from a front surface and a back surface of the substrate, while being heated. The conductive paste is solid-phase sintered and interlayer connecting members are formed. A front surface protective member is disposed on a front surface of the substrate and a back surface protective member is disposed on a back surface of the substrate, and a laminate is formed. The laminate is integrated by a lower pressure being applied while heating at a lower temperature, compared to the temperature and pressure in the process of forming the interlayer connecting members.
