摘要： The object of the invention is to provide an inverter system and vehicles using this inverter wherein accurate detection of the abnormal heat generation from the inverter is ensured, despite a large amount of noise signals, a substantial fluctuation in environmental temperature, or a change of cooling performances resulting from the environmental conditions. Based on the output value of an outside air temperature detecting means 150 and temperature calculation parameters inputted from outside the inverter system, the temperature calculation circuit 144B of an error detecting section 144 calculates the temperature Tcal where a temperature detecting means below semiconductor device 152 is installed. A calculation approximate line calculation circuit 144C works out the approximate curve of the difference between the theoretical temperature value and the real temperature value Treal detected by a temperature detecting means below semiconductor device 152, and captures the trend of the temperature difference, using a periodic sampling method, whereby a error determining circuit 144E determines an error, based on the difference from the initial trend obtained in advance or change of the trend.

摘要： A fault detection system detecting malfunctions or deteriorations, which may result in an inverter fault, is provided. The system has a temperature sensor installed on a semiconductor module to monitor a temperature rise rate. It is judged that an abnormal condition has occurred if the thermal resistance is increased by the deterioration of a soldering layer of the semiconductor module or by drive circuit malfunctions and, as a result, the relation between an operation mode and the temperature rise rate falls outside a predetermined range.

摘要： An air bag apparatus is provided which stably projects the air bag towards the front of a passenger. A retainer 12 stores therein an inflator 14 for injecting gas from gas injection holes at one end of the inflator, and an air bag 15 which is folded. A mid-retainer 16 is provided between inflator 14 and air bag 15. Mid-retainer 16 is provided with a plurality of guide fins 61, which are formed by making cuts in the mid-retainer and bending the cut portions. The direction of gas flow is adjusted by the inclination of each guide fin 61. The gas discharge rate is adjusted by setting various distances between each two adjacent guide fins 61 as to be greatest at the central part of the mid-retainer and either side of the center portion having a gas discharge rate approximately equal to its corresponding opposite side, thereby ensuring air bag 15 will be projected stably.

摘要： The present invention provides a power converter which, while ensuring safety, implements control for the flow of a constant current in a specified switching element, more accurately determines the lifetime of a switching element, and reduces the number of temperature detectors. The power converter is provided with a mechanism which causes a brake device to operate or which confirms that a brake mechanism is operating. The power converter supplies current to the d-axis and the q-axis of a rotational coordinate system, within the range of the braking torque of the brake mechanism, and passes the desired current to the desired element. Furthermore, temperature detectors are attached only in chips in sections where a crack readily develops in the upper solder layer or peeling is readily generated in the wire bonding, and in chips where a crack readily develops in the lower solder layer.

摘要： The threshold value for a normally-off junction FET is a low value. Accordingly, in a semiconductor driver circuit using the normally-off junction FET, there have existed such problems as high-accuracy voltage control, high-speed charging into an input capacitor, and misoperations. A semiconductor driver circuit which is the most suitable for the normally-off junction FET is proposed by applying the high-accuracy gate-voltage generation scheme based on a Zener diode, a reduction in the turn-on loss based on a speed-up capacitor, the connection of an inter-gate-source capacitor, and a misoperation-preventing circuit based on the source-terminal optimum implementation scheme.
