Abstract: A fabrication method of a thermoelectric conversion element includes forming a first metal layer containing Cu on a first surface of a thermoelectric conversion layer, and forming a first electrode and a first intermediate layer from the first metal layer. The thermoelectric conversion layer is composed of a thermoelectric conversion material containing Mg and at least one kind of element selected from the group consisting of Sb and Bi, the first intermediate layer is provided between the thermoelectric conversion layer and the first electrode, the first intermediate layer is in contact with the thermoelectric conversion layer, the first electrode is in contact with the first intermediate layer, and a composition of the first intermediate layer is different from both a composition of the first electrode and a composition of the thermoelectric conversion layer.

Abstract: An engine comprising: a fuel injection device including a rack and an actuator, the rack being configured to regulate the amount of fuel injected to a combustion chamber, the actuator being configured to control the position of the rack; and a control device that controls fuel injection performed by the fuel injection device based on an instructed revolution number, and that performs a dither control on the actuator, wherein the control device has information of a revolution number variation region that is based on the relationship between a dither frequency in the dither control and an engine revolution number, and upon determining that the instructed revolution number is within the revolution number variation region, changes at least one of the dither frequency and the instructed revolution number. Thus, an engine capable of reducing a periodic variation in engine speed which may be caused by a dither control is provided.

Abstract: Electronic control units (ECUs) provided with circuits for backing up other ECUs lack versatility and increase costs. In the present invention, motor control ECUs respectively control motors via signal wires that perform motor control. In addition, a dedicated substitute ECU is connected to each motor via signal wires that perform motor control. A substitute control circuit part of the dedicated substitute ECU runs to a network, is continuously receiving malfunction information and stability information via a signal wire, and detects the malfunction of the motor control ECU from said information. Then the dedicated substitute ECU substitutes for the motor control ECU and performs a backup operation to continue control of the motor via the signal wire.

Abstract: An electronic control apparatus includes a control unit 2; a plurality of power supply units 1-1, 1-2 for supplying the control unit 2 with power; and a power supply fault detector unit 3 for detecting a fault in the plurality of power supply units 1-1, 1-2. The control unit 2 operates in a normal mode on electric power supplied from the plurality of power supply units 1-1, 1-2, when none of the plurality of power supply units 1-1, 1-2 is faulty. If at least one of the plurality of power supply units 1-1, 1-2 is faulty, the control unit 2 operates in an energy saving mode in which less power is consumed on electric power supplied from the power supply unit that remains fully operational. Thereby an electronic control apparatus is obtained that enables continued operation during a faulty condition, while preventing circuit scale, dimensions, weight, and cost from increasing.
