A magnetic head includes a main pole, a write shield, a return path section, a heater that generates heat for making part of a medium facing surface protrude, and a sensor that detects contact of the part of the medium facing surface with a recording medium. In embodiments, a storage medium may have instructions to enable the computing device to monitor interactions with the first computing device by a user of the first computing device. Each of the pixel electrodes includes a plurality of subpixel electrodes electrically separated from one another on an insulating layer. Weighted connections connect to the nodes of the input layer and have coefficients for weighting the input data. When the sample is set on the sample stage and the sample cover is closed, a cover detecting means detects that the sample cover is closed and X-ray is automatically projected from an X-ray source to start analysis.
