    摘要： To enable precise calculation of a propagation time of a direct wave which arrives fastest from an ultrasonic generation source without being affected by a reflected wave of an ultrasonic signal.A plurality of ultrasonic signals generated based on a plurality of M sequences different from each other are propagated from a transmission side to a reception side, whereby the reception side generates model waveforms of the plurality of M sequences, executes correlation processing between each model waveform and a waveform of each ultrasonic signal and detects a secondary peak of a correlation value which appears when both waveforms partly coincide with each other to determine an M sequence which generates a smallest secondary peak among secondary peaks detected by all the correlation processing as an optimum M sequence. The transmission side sends out an electromagnetic signal and an ultrasonic signal modulated by an optimum M sequence generated based on an initial condition of the optimum M sequence to the reception side. The reception side calculates a correlation value between the ultrasonic signal and a model waveform of the ultrasonic modulated by the optimum M sequence, detects a first primary peak of the calculated correlation value and calculates an ultrasonic propagation time from a time point of the reception of the electromagnetic signal and a time point of the detection of the primary peak.

    摘要： Disclosed is an electronic pen system wherein re-calibration can be easily carried out when a receiver is re-attached or when the position of the receiver is varied after calibration to adjust the position of the pen with respect to the receiver to the position of the pen on the image projected by a projector or the like. The system comprises a measuring means for measuring the angle of variation from the initial setting of the receiver for measuring the position of the electronic pen to the re-setting of the receiver and the amounts of movement in the horizontal direction and the vertical direction from the initial setting to the re-setting and a display means for reflecting the measured angle of variation and the measured amounts of movement in the horizontal direction and the vertical direction on the trace of the electronic pen after the re-setting.

    摘要： In a head positioning mechanism has a micro tracking actuator which is between a carriage and a supporting spring for making the supporting spring be rotated relative to the carriage to adjust a position of a magnetic head, the micro tracking actuator has a pair of coils held to one of said carriage and said supporting spring. Each of the coils generates magnetic flux in response to a flow of electric current therein. The micro tracking actuator further has a magnet arrangement held to another of the carriage and the supporting spring to face the coil means in a predetermined direction. The magnet arrangement traverses the magnetic flux to have a particular size which varies in accordance with a predetermined relation in response to a relative movement between the coils and the magnet arrangement. The carriage is movably mounted to a magnetic disk device to which the head positioning mechanism applied. The supporting spring is attached to the carriage and rotatable around a predetermined axis extending in the predetermined direction. The supporting spring holds the magnetic head to perform a seeking operation of the magnetic head in cooperation with the carriage.
