The present invention realizes reduction of position information demodulation errors caused by the eccentricity of the magnetic disk and improvement of position signal detection accuracy, as well as enabling quick eccentricity clock correction for arbitrary clock frequencies. An inspection device in accordance with the present invention comprises: a servo demodulation unit which demodulates servo information; a PLL clock generating unit which generates a reference clock and supplies the reference clock to the servo demodulation unit; and a tester control unit. The PLL clock generating unit includes an eccentricity correction circuit for correcting the frequency of the reference clock depending on the eccentricity of the magnetic disk. The tester control unit generates correction data for correcting the frequency of the reference clock, multiplies the correction data by the inverse of a transfer function of the PLL clock generating unit, and supplies the product to the eccentricity correction circuit.

A magnetic head position control method is provided to control a magnetic head to follow the track on a DTM (discrete-track magnetic) disk by accurately detecting the eccentricity compensation amount through a simple process. An angle detection unit detects θ1 at which the relative displacement between the magnetic head and the tracks on the DTM (discrete-track magnetic) disk has a peak with no vibration data added. A vibration data calculation unit calculates first vibration data with first vibration amplitude, so that the displacement has a peak at θ2 displaced from θ1 by a predetermined value. The angle detection unit detects θ3 at which the relative displacement has a peak with the first vibration data added. A compensation data calculation unit calculates compensation data for the eccentricity of the tracks, from the detected angles θ1, θ3, the first vibration amplitude, and θ2. The position of the magnetic head is compensated according to the correction data.

A corrosion detection method detects galvanic corrosion occurring in a heterogeneous metal layer using a forming step and an observing step. The forming step is the step of forming the heterogeneous metal layer and a monitoring pattern by electrolytic plating a plurality of types of metal layers on a substrate. The observing step is the step of observing a surface of the monitoring pattern from above. The monitoring pattern has an identical structure of the heterogeneous metal layer. The monitoring pattern is in an area different from an area in which the heterogeneous layer is formed on the substrate.

Traffic situation determination systems, methods, and programs acquire a current position of the vehicle based on a radio signal received from a GPS satellite and determine a first travel path of the vehicle based on the acquired position of the vehicle. The systems, methods, and programs determine whether a road on which the vehicle is traveling has a traffic jam. If the road on which the vehicle is traveling has a traffic jam, the systems, methods and programs transmit first information relating to the first travel path from the vehicle to an information center. The systems, methods, and programs receive second information relating to a second travel path of the vehicle, the second information being received from a mobile phone communication center and being based on a mobile phone signal received by the mobile phone communication center. The systems, methods, and programs determine a road corresponding to the first travel path as having a traffic jam and determine a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam.

The present invention aims at providing a method for measuring spinorphin in a sample collected from a living body accurately with high sensitivity. The present invention provides a method for measuring spinorphin in a sample collected from a living body, comprising the steps of: (A) mixing a sample collected from a living body with trichloroacetic acid to give a solution phase and subjecting said solution phase and a solvent to a reverse phase column to elute spinorphin with said solvent; (B) contacting the spinorphin eluted in the step (A) with spinorphin immobilized on a carrier and a spinorphin antibody; (C) removing the spinorphin antibody that has not been bound to the spinorphin immobilized on the carrier; (D) contacting the spinorphin antibody bound to the spinorphin immobilized on the carrier obtained in the step (C) with a labeled secondary antibody that specifically binds to said spinorphin antibody so as to bind the spinorphin antibody bound to the spinorphin immobilized on the carrier and the labeled secondary antibody; and (E) measuring the amount of label in the labeled secondary antibody bound to the spinorphin antibody.
