摘要： An electromagnetic field detecting element 10 includes a lamination of three insulation layers 2, 3, and 4. The dielectric breakdown strength of the insulation layer 3 is greater than the dielectric breakdown strengths of insulation layers 2 and 4. The three insulation layers 2, 3, and 4 are disposed between a pair of electrodes 5 and 6. Boundaries 7 and 8 on both ends of an overlapping region of the opposing surfaces 5a and 6a in a Z direction are apart from the insulation layer 3 by thicknesses t1 and t3 of the insulation layers 2 and 4, respectively. Between the pair of electrodes 5 and 6, ballistic current paths interposing therebetween the insulation layer 3 are formed by applying, between the pair of electrodes 5 and 6, an electric field having a magnitude which causes dielectric breakdown in the insulation layers 2 and 4 while causing no dielectric breakdown in the insulation layer 3. Thus, it is possible to perform at a room temperature a highly efficient electromagnetic field detection utilizing AB effect or AC effect.

摘要： A machine tool capable of detecting an ambient temperature change without a detector for detecting the ambient temperature and capable of detecting an abnormality of a temperature detector for detecting the motor temperature. Motor temperature Ti (i=1, 2 . . . n) and the current feedback Ifi of each motor are read out from the temperature detector for detecting the temperature of each motor of the machine tool. The heating value Qi of each motor is obtained from current feedback Ifi. Motor temperature Ti is calculated and estimated from the heating value Q. Difference ΔTi between the estimated motor temperature Tmi and the detected temperature Tsi is obtained. When difference between maximum and minimum values of difference ΔTi exceeds the first threshold value β, a temperature detector abnormality is outputted. When it is equal to or less than the first threshold value β, the mean value ΔT′ of differences is obtained. If the mean value ΔT′ is equal to or less than the second threshold value γ, it is determined that there is no abnormality. If it is equal to or more than the second threshold value γ, the indication that the ambient temperature has been changed is outputted.

摘要： An electromagnetic field generating element restrains magnetic field attenuation or magnetic field delay in a high frequency recording/reproducing head for thermally assisted magnetic field recording/reproduction using a near field. An information recording/reproducing head and an information recording/reproducing apparatus carry out high frequency magnetic recording/reproduction. The electromagnetic field generating element 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 irradiates laser light to the plate-like-shaped conductor substantially parallel to an extending flat surface of the plate-like-shaped conductor. This causes generation of a near field in the plate-like-shaped conductor. In addition, a magnetic field is generated by supplying a current to the plate-like-shaped conductor.

摘要： A machine tool having a low-cost pallet change function and a pallet changing method, in which a pallet is conveyed by utilizing a robot for handling a workpiece. Rollers are rotatably arranged on the pallet. The rollers are supported and rolled on rails that are arranged on a pallet changer base and a table of the machine tool. The pallet has a handle. The robot engages the handle by its hand and pulls or pushes the pallet, thereby moving the pallet between the base and the table. On the base, moreover, the robot mounts or dismounts the workpiece on or from the pallet. Since the movement of the pallet requires no substantial force, the robot for handling the workpiece can convey the pallet and change the pallet at low cost.

摘要： The present invention provides a magnetic signal reproducing device including heating means for locally heating a reproducing region of a magnetic recording medium, first reproducing means for reading magnetic information in the reproducing region in a first temperature state to obtain a first reproduced signal, second reproducing means for reading magnetic information in almost the same region as the reproducing region in a second temperature state which is different from the first temperature state to obtain a second reproduced signal, and correcting means for correcting the first reproduced signal based on the second reproduced signal to obtain an information reproducing signal representing information recorded in the reproducing region. According to this, even if a medium temperature in a non-heated region of the magnetic recording medium is shifted from a magnetization compensation point, a signal from the region is prevented from mixing into a reproducing signal.

摘要： The position of a feed shaft is monitored, the mean moving speed and moving frequency of the feed shaft are measured with every unit time for position correction, and a correction amount &dgr;n is determined from the speed and frequency according to an approximation formula and updated (c7 and c8). A position correction amount for a commanded position is determined from this correction amount, and the commanded position is corrected by the position correction amount (c1 to c6). The position correction amount for the commanded position is determined from this correction amount, and the commanded position is corrected by this position correction amount. Since the correction amount is determined according to the approximation formula, thermal displacement correction can be effected at all times without requiring any sensor. When the correction amount changes substantially (c10), the thermal displacement is measured by means of a sensor and used as the correction amount (c11 and c12), whereby accuracy is improved. The frequency of measurement by means of sensors is reduced, so that the machining time can be reduced.

摘要： A mold for molding a drum shaped magnetic core having two flanges connected by a coil winding core portion. The mold includes a die defining a cylindrical cavity having an inner diameter substantially equal to an outer diameter of the flanges. A pair of die inserts are movable in an orthogonal direction relative to the cylindrical cavity and define a diameter of the coil winding core portion of the drum shaped magnetic core. The diameter of the coil winding core portion is smaller than the outer diameter of the flanges. An upper punch and a lower punch are inserted into the cylindrical cavity from a corresponding end opening of the mold such that each forms a flange. A central punch is disposed coaxially within one of the punches to form the coil winding core portion.

摘要： A light sensor is divided into two light receiving sections which receive light reflected by an optical disk. A first intermediate address signal is generated from a difference signal of outputs of the light receiving sections. A second intermediate address signal is generated from a sum signal of outputs of the light receiving sections. An address generating circuit generates an address signal by using the first and second intermediate address signals. An optical disk device stably generating an address signal regardless of a displacement of an objective lens and a change in reflectance of the optical disk is thus provided.
