Abstract: PURPOSE:To detect the coincidence of two sets of AC power sources without being affected by a frequency change or change of circuit parts constant, etc. by outputting a logical H signal when an AC voltage is in a positive region and a logical L signal when said voltage is in a negative region. CONSTITUTION:The AC voltages outputted from a commercial power source 2 and an inverter 4 are respectively converted to the logical H signal in the positive voltage region and to the logical L signal in the negative voltage region by signal converters 30, 31.

The degree of the phase difference between the two power source voltages is detected by an exclusive OR element 33. The polarity of the input signal to an integrator 37 is changed over by the output signal of the FF32 and the integration time of the integrator 37 is changed over so as to meet the output signal of the element 33. The phase difference between the two AC power source voltages is detected from the quantity obtd. by holding 38 the peak value of the output from the integrator 37.

Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To protect seeking strength and to suppress positioning errors by detecting the resonance of a head arm caused by the fluctuation of a friction force as an external disturbance and canceling the disturbance. SOLUTION: By eliminating a high-frequency component from the output signal of an addition circuit 32a with a low-pass filter 50, the low-frequency component of a friction force is detected. This is converted into a digital signal by an AD converter 51, its value is made corresponsive to a position and stored in a memory, and then this is used as a feed forward compensation signal for following control. At the time of starting a magnetic disk device or the like, a sector friction force is detected for each track, this operation is repeated by several times and an addition average value is calculated by a CPU 40, and this average value is stored in the memory as a position dependent component.  The stored position dependent component of the friction force is read corresponding to a head position, a gain is multiplied and code-inverted when necessary, and then by offsetting the addition and position dependent components from a digital operation amount signal, positioning accuracy is improved.
