An angular rate sensor includes: a support substrate; a semiconductor layer; and a movable portion. Each player has chips and takes turns depositing the chips in the end pieces around the board. The second peeling step is to pull up the other pair of opposite portions of the lens sheet to peel partially the lens sheet from the forming mold. Furthermore, the fluorescent tubes will act as a reflector due to the angled position. The shaped signal pattern generation circuit 15 refers to the variation pattern information and calculates an optimum signal pattern corresponding to a signal length and a signal level of the inputted, returning light signal. Brain states in unlabeled EEG data are classified using the classifier model by dividing the unlabeled EEG data into overlapping time windows and removing the time dimension from each time window.
