Abstract: In a case where a detector is positioned in a [11-20] direction, and where a first measurement region including a center of a main surface is irradiated with an X ray in a direction within ±15° relative to a [?1-120] direction, a ratio of a maximum intensity of a first intensity profile is more than or equal to 1500. In a case where the detector is positioned in a direction parallel to a [?1100] direction, and where the first measurement region is irradiated with an X ray in a direction within ±6° relative to a [1-100] direction, a ratio of a maximum intensity of a second intensity profile is more than or equal to 1500. An absolute value of a difference between maximum value and minimum value of energy at which the first intensity profile indicates a maximum value is less than or equal to 0.06 keV.

Abstract: An ECU (1) includes a circuit board (10), a connector (20) fixed to the circuit board (10), and a resin portion (50) covering the circuit board (10) and the connector (20). The connector (20) includes a connector housing (21) having a terminal holding wall (22) that separates the internal space from the external space, and terminal fittings (41) extend through the terminal holding wall (22). The connector housing (21) includes a surrounding wall (27) disposed on the lateral surface of the terminal holding wall (22) to surround the terminal fittings (41). A potting material (28) is disposed inside the surrounding wall (27) and separates the terminal holding wall (22) from the resin portion (50). This can prevent a melted resin from entering a hood (24) through press fitting holes (23) at the time of forming the resin portion (50) by mold forming.

Abstract: An ECU 1 includes a circuit board 10, a connector 20 fixed to the circuit board 10, a resin portion 50 covering the circuit board 10 and the connector 20. A buffer portion 60 is interposed between the circuit board 10 and the connector 20, between the circuit board 10 and the resin portion 50, or between the connector 20 and the resin portion 50. This configuration enables the buffer portion 60 having elasticity to absorb the stresses generated due to differences in linear expansion coefficient in the boundary portion between the circuit board 10 and the connector 20, the boundary portion between the circuit board 10 and the resin portion 50, and the boundary portion between the connector 20 and the resin portion 50. This makes it possible to prevent the connector 20 from peeling from the circuit board 10.

Abstract: An electrode is constituted by a sheet-shaped porous body and used in an electrolyte-circulating battery that performs charging and discharging by circulating an electrolyte. Assuming that a portion of a side surface of the electrode that is adjacent to an inlet for the electrolyte when the electrode is installed in the electrolyte-circulating battery is an inlet end surface and a portion of the side surface of the electrode that is adjacent to an outlet for the electrolyte when the electrode is installed in the electrolyte-circulating battery is an outlet end surface, the electrode includes a first flow channel that is connected to the inlet end surface and extends toward the outlet end surface and a second flow channel that is connected to the outlet end surface and extends toward the inlet end surface. The first flow channel and the second flow channel do not directly communicate with each other.
