    摘要： This specification discloses inventions of a rotation detecting device for a rotary shaft and of a rotation controlling apparatus using this rotation detecting device. The rotation detecting device according to the invention comprises a signal generator for generating two signals vary their amplitude in accordance with the rotation angle of the rotary shaft and have a predetermined phase difference therebetween, part for correcting the respective center voltages output from the signal generator, part for correcting a deviation from the phase deviation between the two signals, and part for correcting the rotating amounts of the rotary shaft on the basis of the corrected two signal. The rotating amounts are represented in terms of rotating angles. A rotating torque can be obtained by calculating a difference between the rotating angles measured at two points apart from each other on the rotary shaft. The rotary shaft can be controlled in accordance with the rotating angle or the rotating torque.

    摘要： An output of a electric driven blower in a cleaner main body is controlled in response to a detection value of a pressure sensor which detects an operation condition in the cleaner main body. A change-over level setting value is provided as a control value for the sensor so as to form a judgment point for changing over a control condition of the blower. A return level setting value is provided as a control value for the sensor so as to form a judgment point for returning to a previous control condition of the blower from a changed-over condition of the blower. When the detection value of the sensor is more than the change-over level setting value, the return level setting value is set higher than the change-over setting value, thereby the output of the blower is increased, or the return level setting value is set a lower than the change-over level setting value, thereby the output of the blower is decreased.
