Abstract: A multilayer electronic device includes an element body including an interior region and an exterior region and a pair of external electrodes. The interior region includes inner dielectric layers and internal electrode layers laminated alternately. The exterior region is disposed outwards from the interior region in a lamination direction. The pair of external electrodes is disposed on a surface of the element body and connected to the internal electrode layers. DRAa<DRAb<DRAc and DRBa>DRBb>DRBc are satisfied, where “RA” includes an element having a highest mole ratio among “RE” in the inner dielectric layers of a third region at a center of the interior region in the lamination direction, “RB” includes an element having a highest mole ratio among “RE” in a first region at a center of the exterior region in the lamination direction, and “RA” and “RB” are different from each other.

Abstract: The present invention provides an information provision system that provides a user with information for coping with a problem by using an information terminal having a camera and a display, wherein the information terminal includes at least one processor with a memory comprising instructions cause the at least one processor to at least: identify a problem area in a captured image obtained by the camera; and display, on the display, a plurality of procedure screens indicating contents of a procedure for coping with the identified problem area, in accordance with an answer from the user, the plurality of procedure screens include a first procedure screen on which a plurality of answer items selectable by the user are displayed.

Abstract: A heat exchanger includes a core and a header. At least one of first header portions or second header portions includes a guiding flow passage that has a plurality of flow passages which guide a fluid between a plurality of core end openings and a tank while changing a flow passage sectional shape.

Abstract: This aircraft heat exchanger includes a heat exchanger body, which includes: a temperature raising section configured at least to raise a temperature of the heat exchanger body locally; and a heat exchanging section configured to exchange heat between an aircraft fuel and oil. The temperature raising section has an inlet for the oil, and has its temperature raised by the oil that has entered the heat exchanger body through the inlet. The heat exchanging section has an outlet for the aircraft fuel. The oil that has passed through the temperature raising section is introduced into the heat exchanging section from around the outlet for the aircraft fuel. The heat exchanging section is configured to have counter flows.
