摘要： A semiconductor device accurately monitoring temperature of a semiconductor chip even in a noisy environment, while not requiring a highly accurate detection circuit. A PTC element is bonded onto an IGBT chip. Then, a constant current flows from a constant current source through the PTC element, and an output voltage of the PTC element is detected by a voltage monitor. When output voltage increases, a voltage applied to a gate electrode by a detection circuit is decreased. Since the PTC element is directly arranged on the IGBT chip, the temperature of the IGBT chip can be monitored with high accuracy. Further, since the change in output voltage of the PTC element per 1° C. is large, a highly accurate detection circuit is not necessary, thereby allowing accurate monitoring of the temperature of the IGBT chip even in a noisy environment.
摘要翻译：半导体器件即使在嘈杂的环境中也能准确地监测半导体芯片的温度，同时不需要高精度的检测电路。 PTC元件接合在IGBT芯片上。然后，恒定电流从恒定电流源流过PTC元件，并且通过电压监视器检测PTC元件的输出电压。当输出电压升高时，由检测电路施加到栅电极的电压降低。由于PTC元件直接配置在IGBT芯片上，因此可以高精度地监视IGBT芯片的温度。此外，由于PTC元件每1℃的输出电压变化大，因此不需要高精度的检测电路，因此即使在嘈杂的环境下也能够精确地监视IGBT芯片的温度。

摘要： A normally closed solenoid valve includes a fixed core, a valve portion including a valve seat and a valve body, a movable core disposed between the fixed core and the valve seat, a resilient biasing member for biasing the movable core in a valve-closing direction and a coil. When energized, the coil generates an attracting force between the movable core and the fixed core against a biasing force by the resilient biasing member to cause the movable core to retreat from an initial position where the valve seat is in a closed state. When a characteristic graph line of spacing distance/attracting force that defines the attracting force in relation with a spacing distance between the fixed core and the movable core provides an inclination A (N/mm) at the initial position, the compression resiliency coefficient of the resilient biasing member is set to A (N/mm).

摘要： A drive circuit includes a gate voltage detector that detects a gate-emitter voltage Vge that appears between the gate and emitter of a power semiconductor device throughout a detection time period during which a sampler allows the process of detecting the gate-emitter voltage Vge, and that recognizes the occurrence of an abnormality in the power semiconductor device when the gate-emitter voltage Vge exceeds a reference value. Therefore, the drive circuit can protect the power semiconductor device with higher reliability by promptly detecting the occurrence of a short circuit even when the power semiconductor device is resistant to high voltages.

摘要： In an IGBT module which contains an IGBT device and a diode device connected to each other and accommodated in a case and which radiates heat generated in operation through a radiation board, an object is to reduce the area of the module in the lateral direction to achieve size reduction. The collector electrode surface of an IGBT device is provided on a radiation board, and an element connecting conductor is bonded with conductive resin on the emitter electrode surface. The anode electrode surface of a diode device is bonded on it with the conductive resin. The IGBT device and the diode device are thus stacked and connected in the vertical direction.
