    • An integrated sensor includes a pressure sensor element integrated with a temperature sensor element (109). When the sensor is attached to an object of attachment (200) at a mounting position at an angle of θ rq degrees with respect to an ideal attachment position, in which a central axis (c) of at sensor element body (109a) of the temperature sensor element (109) is disposed perpendicular to a direction in which a gas to be measured passes through the object of attachment, an inclination angle θ pos at which the central axis (c) of the sensor element body (109a) is inclined at the mounting position with respect to a position of the central axis (c) of the sensor element body (109a) at the ideal attachment position is set according to the following equation: θ rq - θ allow ≤ θ pos ≤ ( θ rq + θ allow )
      wherein θ allow represents an allowable angle at which an allowable response speed of the temperature sensor element (109) is obtained.

    • In an AC motor driving circuit, a current source rectifier 2 is provided on the output side of an AC generator 2 and an AC motor 4 is connected to the output side of the current source rectifier 2 through a voltage source inverter 3. Along with this, one of terminals of each of a plurality of bidirectional switches 6 is connected to its own corresponding output terminal of the voltage source inverter 3, the other terminals of a plurality of the bidirectional switches 6 are lumped together to be connected to the one of terminals of a DC power source 5, and the other terminal of the DC power source 5 is connected to one of DC input terminals of the voltage source inverter 3. This eliminates need for a large capacitor at a DC link and a reactor in a chopper which were previously necessary, by which the AC motor driving circuit is downsized.
    • 在交流电动机驱动电路中,电流源整流器2设置在交流发电机2的输出侧,交流电动机4通过电压源逆变器3与电流源极整流器2的输出侧连接。与此同时 多个双向开关6中的每一个的端子中的一个连接到其本身的电压源逆变器3的相应的输出端,多个双向开关6的另一个端子被集中在一起以连接到端子 直流电源5的另一个端子连接到电压源逆变器3的直流输入端中的一个。这不需要在直流链路处的大电容器和斩波器中的电抗器 以前是必要的,由此AC电动机驱动电路被小型化。
