    摘要: According to one embodiment, a temperature detection circuit is provided which requires only a small number of additional components, thus minimizing an increase in costs and which offers an insulating property and high responsiveness. A temperature detection circuit outputs a first PWM signal corresponding to a temperature of a first temperature sensor from a photointerrupter as a signal insulated from the first temperature sensor. A temperature detection circuit outputs a second PWM signal corresponding to a temperature of a second temperature sensor from a photointerrupter as a signal insulated from the second temperature sensor. A controlling arithmetic apparatus calculates a higher one of the temperatures detected by the first and second temperature sensors based on the PWM signals output from the photointerrupter.

    摘要: An inverter apparatus according to one embodiment includes switching elements and freewheel diodes which are connected to a direct-current power supply, a temperature detector provided near at least one of the switching elements, and a temperature estimation unit. The temperature estimation unit estimates temperatures of switching elements not provided with the temperature detector, based on an estimated-temperature increase value calculated by a loss model of the switching elements and freewheel diode and others, and a temperature of the switching element detected by the temperature detector.

    摘要: An electromagnetic fuel injection valve wherein a central pipe part has satisfactory mechanical strength and an intermediate portion of the pipe part is surely made non-magnetic is provided. The electromagnetic fuel injection valve has a core surrounded by a solenoid coil. A valve housing is disposed forward of the core. The core and the valve housing are connected through a thin-walled portion. The wall thickness of the thin-walled portion is smaller than the wall thickness of the core and that of the valve housing. The core and the thin-walled portion, together with the valve housing, are formed in an integral structure. The thin-walled portion has a sufficient wall thickness to provide satisfactory mechanical strength. The thin-walled portion is modified into a high-hardness non-magnetic portion by a carbulizing treatment.
