Abstract: A mass flowmeter includes a flow sensor having a first sensor part and a second sensor part formed on both sides of a heater part. The flow sensor is formed of a thermoplastic resin, and is configured of a multi-layer substrate including a plurality of stacked insulating layers, and a first conductor and a second conductor and formed on these insulating layers and connected to each other. The multi-layer substrate is formed by pressurizing and heating the plurality of insulating layers for integration. When a fluid having heat released from the heater part is moved along the one face of the flow sensor, the first and the second sensor parts and generate electromotive forces in the level corresponding to temperature differences generated between the one face and the other face in the first and the second sensor parts. The flow sensor has a structure manufactured by pressurizing and heating the plurality of insulating layers for integration. The structure has no large space unlike a structure having a space immediately below a diaphragm. Thus, the flow sensor is less breakable than a sensor having a diaphragm structure is.

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: 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 measuring instrument for a physiological heat quantity emitted from a human body includes a heat flux sensor, and a calculator. The heat flux sensor includes a sensor main body portion and a moisture absorbing member. The sensor main body portion has multiple through holes penetrating through the sensor main body portion from a first surface to a second surface. The sensor main body portion is disposed on a human body such that the first surface is adjacent to the human body when in use, and outputs a sensor signal according to a heat flux passing through the sensor main body portion from the first surface toward the second surface. The moisture absorbing member is stacked on the second surface of the sensor main body portion. The calculator calculates the physiological heat quantity based on the sensor signal.

Abstract: 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.

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.
