  • Patent number: 12260888
    Abstract: According to the embodiment, a controller of a magnetic disk apparatus acquires a first amplitude and a first phase of a first read waveform and a second amplitude and a second phase of a second read waveform by demodulating the first/second read waveforms. The first read waveform is a read waveform of a first burst pattern. The second read waveform is a read waveform of a second burst pattern. The controller acquires weights on the basis of the first amplitude, the second amplitude, the first phase, and the second phase. The controller corrects an initial phase of each of the first read waveform and the second read waveform by calculating a weighted average using the weights, the first phase, and the second phase. The controller executes positioning of the magnetic head on the basis of the corrected first read waveform and second read waveform.

  • Patent number: 12262220
    Abstract: An apparatus includes antenna, selector, estimator, imager and creator. The antenna includes antenna elements of N rows by N columns (N is a natural number of 2 or more) arranged in an array and captures an incoming wave. The selector selects an antenna element group including antenna elements of M rows by M columns (M is a natural number less than N) from the antenna elements of N rows by N columns according to a band of the incoming wave. The estimator estimates an incoming direction of the incoming wave from an element signal of each of the antenna elements included in the selected antenna element group. The imager acquires image data by imaging an orientation direction of an aperture of the antenna. The creator creates a visualized image by visually synthesizing the estimated incoming direction with the image data.

The processor serves to identify, as resonant frequency of components of a structure, frequency of first-type peaks included in a first-type transfer function waveform representing relationship between amplitude and frequency of output vibration. The output vibration occurs in the components of the structure when the structure is subjected to sweep excitation. The processor serves to calculate a vibration propagation path along which input vibration having the resonant frequency propagates when applied to the structure. The vibration propagation path is calculated based on frequency and half width of second-type peaks included in a second-type transfer function waveform representing relationship between amplitude and frequency of output vibration.
