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.

Third via holes of a second insulator are filled with a second conductive paste. Next, parts of the first conductive paste protruding from the first via holes of the first insulator are inserted into fourth via holes of the second insulator. Parts of the second conductive paste protruding from the third via holes of the second insulator are inserted into second via holes. Next, a rear surface protection member having rear surface wiring patterns, the second insulator, the first insulator, and a front surface protection member having front surface wiring patterns are arranged in this order to form a stacked body. Next, the stacked body is heated while being pressed in the stacking direction.
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.

Abstract:
According to a manufacturing method of a heat flux sensor, the heat flux sensor is sandwiched between a heater plate and a cooling unit. The heater plate is disposed on the first surface of the heat flux sensor, and the cooling unit is disposed on the second surface of the same. A heat radiation measurement plate is disposed on a surface of the heater plate opposite to the surface on which the heat flux sensor is disposed. According to this configuration, the temperature of the heater plate is controlled in an inspection process such that the heater plate is kept at an ambient temperature. This makes it possible to stabilize the temperature of the heater plate in a short time.
Abstract:
As the first conductive paste, a paste is used which is made by adding an organic solvent to powder of alloy in which a plurality of atoms keep a given crystal structure constant. As the second conductive paste, a paste is used which is made by adding an organic solvent to powder of metal different in kind from the alloy. In a step of making the stack body, cavities are formed in the stack body. In a uniting step, the cavities work to facilitate flow of thermoplastic resin to absorb pressure acting in a direction different from a direction in which pressure exerted on the first conductive paste to unite the stack body, thereby resulting in an increase in pressure for the uniting to solid-state sinter the first conductive paste to make the first layer-to-layer connecting member.
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 alloy, 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.

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.
