  • Patent number: 9620699
    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.

  • Publication number: 20160273952
    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.

  • Publication number: 20160121847
    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.

  • Publication number: 20160059669
    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.
