摘要： A snow removing machine equipped with a snow removing plate is disclosed. The snow removing plate is mounted to a front portion of a vehicle body which forms part of the snow removing machine. An operating handle having grip portions is mounted to a rear portion of the vehicle body and obliquely extends upward. A battery, an electric motor and a power transmission mechanism are located below a linear line intersecting between an upper end of the snow removing plate and the grip portion. This causes the battery, the electric motor and the power transmission mechanism to be located below a view line of an operator when he looks at the snow removing plate, avoiding the view line from being disturbed to allow the operator to look at the upper end of the snow removing plate in his working attitude for thereby providing ease of operation of the snow removing machine.

摘要： In a semiconductor device including a power MOSFET (M.sub.0) for the output stage, a temperature detection circuit produces an output signal upon detecting an abnormal rise in the chip temperature, the signal turns on a set input element (M.sub.1) in a latch circuit so that the latch circuit becomes a set state, the set output of the latch circuit turns on a control element (M.sub.5), causing the power MOSFET to become non-conductive so that it is protected from destruction. The latch circuit is not brought to a reset state even if the external gate terminal of the device is brought to zero volt. With a voltage outside the range of the normal input signal, e.g., a large negative voltage, being applied to the external gate terminal, the gate capacitance of the control element (M.sub.5) discharges, and consequently the latch circuit is brought to the reset state and the protective operation is cancelled. The semiconductor device is further provided with an external reset terminal, and the protective operation can also be cancelled through the application of a reset signal to the external reset terminal. The semiconductor device is protected from destruction and also from deterioration of characteristics of the power MOSFET (M.sub.0), and yet the protective operation is not cancelled erroneously by the normal input signal.

摘要翻译： 在包括用于输出级的功率MOSFET（M0）的半导体器件中，温度检测电路在检测到芯片温度的异常升高时产生输出信号，该信号使锁存电路中的设定输入元件（M1）接通，从而 锁存电路变为置位状态，锁存电路的设定输出导通控制元件（M5），使功率MOSFET变得不导通，从而防止其破坏。 即使器件的外部栅极端子达到零伏，锁存电路也不会进入复位状态。 在外部栅极端子施加正常输入信号（例如，大的负电压）的范围之外的电压时，控制元件（M5）的栅极电容放电，因此锁存电路进入复位状态 并且保护操作被取消。 半导体器件还具有外部复位端子，并且还可以通过向外部复位端子施加复位信号来取消保护操作。 保护半导体器件不受破坏，也可以防止功率MOSFET（M0）的特性恶化，而保护操作也不会被正常输入信号错误地消除。
