摘要： An automatic tool changing method and an automatic tool changing device for a machine tool with a numerical controller capable of reducing the occurrence of impact due to tool exchange with a simple structure. A turret that rotates about a pivot shaft is provided on an arm and holds multiple tools. A swing cam CS that cooperates with a swing roller provided on the turret is provided on a spindle head. As the spindle head descends the turret rotates due to the action of the swing roller and the cam CS and exchanges tools. In order to lessen the impact that occurs at this time, the velocity of the spindle head is controlled. The ideal swing velocity pattern for the turret is obtained, and from this swing velocity pattern the swing position of the turret at each moment is obtained. From the swing roller and cam CS positions at this position the position of the spindle head 34 is obtained. From the acquired spindle head position the spindle head velocity pattern is obtained, and the spindle head is controlled using this velocity pattern. As a result, an ideal swing pattern can be achieved, and therefore no impact arises.

摘要： The present invention provides an electromagnetic field generating element, an information recording/reproducing head, and an information recording/reproducing apparatus. The electromagnetic field generating element makes it possible to restrain magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for use in thermally assisted magnetic field recording/reproduction using a near field. The information recording/reproducing head and the information recording/reproducing apparatus can carry out high frequency magnetic recording/reproducing. The electromagnetic field generating element of the present invention includes: (i) a substrate, (ii) conductors each provided on the substrate and each serving as a supporting section, (iii) a plate-like-shaped conductor provided on the conductors and (iv) a semiconductor laser element provided on the substrate. The semiconductor laser element irradiated, to the plate-like-shaped conductor, laser light substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of the near field in the plate-like-shaped conductor. Moreover, a magnetic field is generated by supplying a current to the plate-like-shaped conductor.

摘要： A magnetic storage medium includes a magnetic storage medium that exhibits a magnetic compensation temperature specified higher than room temperature to minimize effects of heat generated by a head using magneto-resistance effect. In a heat assisted recording and reproduction method using such a magnetic storage medium, during reproduction, the S/N ratio in a reproduction signal is enhanced by optimizing the bias current applied to the head using magneto-resistance effect. A magnetic storage medium and a heat assisted recording and reproduction method using such a magnetic storage medium whereby information is magnetically recorded and reproduced by heating a read-out domain are offered that enables signal reproduction with a good S/N ratio despite possible use of a head exhibiting magneto-resistance effect.

摘要： In a machine tool controlled by using a numerical control device, a correction amount is determined for thermal displacement due to heat generation and heat conduction in a spindle motor and a feed shaft motor, in addition to thermal displacement due to heat generated by rotation of a spindle and a feed shaft. A tool position is corrected based on the correction amount. An entire stroke of the feed shaft is divided into a finite number of sections, and for each section, a correction amount for thermal displacement due to axial movement of the feed shaft is determined. The tool position is corrected based on the determined correction amount.

摘要： An information recording and reproduction apparatus uses a recording medium that contains information which prohibits digital copying. A reproduction section reproduces the desired informatiion stored on a first recording medium. A recording section records the reproduced output at a desired position on a second recording medium. However, an erasing section erases the information from the first recording medium during the process of recording that information on the second recording medium. The first and/or second recording medium cannot be removed from the information recording and reproduction apparatus until the erasing operation is completed.
