    摘要: A magneto-optical information recording/reproducing apparatus in which a magneto-optical information recording medium at least including a first magnetic film having perpendicular magnetic anisotropy, and a second magnetic film to which information recorded on the first magnetic film is transferred by irradiation of a laser beam, is used so that a readout laser beam is irradiated onto the second magnetic film to thereby readout the information transferred to the second magnetic film. The apparatus includes a 2-split detection circuit for receiving the readout laser beam reflected from the second magnetic film of the recording medium, and a subtraction circuit in which output signals of the two detection elements of the 2-split detection circuit are subtracted from each other to generate a differential signal. The apparatus further comprises a circuit for making a spot of the laser beam jump one track before readout of the information from the magneto-optical information recording medium, a positive/negative balance correction circuit for detecting an amplitude ratio between positive and negative side amplitudes in a track jump signal generated in the differential signal from the subtraction circuit in response to the track jump to thereby output a correction signal in accordance with the amplitude ratio, and an addition circuit for adding the correction signal to the differential signal to thereby generate a tracking error signal for tracking control used in readout of the magneto-optical information from the magneto-optical information recording medium.

    摘要: [Object] To provide a pointing system capable of presenting an intuitive operational feeling to a user.[Solving Means] A pointing device includes a casing, a tactile sense presentation section, and a sensor section. The sensor section detects an operation for the casing and outputs an operation signal for controlling a movement of a pointer on a screen. The control apparatus includes an area setting section and a signal generation section. The area setting section sets a first area that belongs to an inside of a display area of an object on the screen, a second area that belongs to an outside of the display area of the object, and a third area that belongs to a boundary portion between the first area and the second area. The signal generation section calculates a position of the pointer based on the operation signal to generate, when the pointer is located in the first area, a control signal by which the tactile sense presentation section is driven in a first drive mode and generates, when the pointer is located in the third area, a control signal by which the tactile sense presentation section is driven in a second drive mode.

    摘要: The method for producing flaky-glass granules of the present invention is a method for producing flaky-glass granules by allowing a plurality of glass flakes to be bonded to each other so as to be granulated. The method includes the steps of: (I) adding at least one liquid selected from water and a volatile organic solvent to the plurality of glass flakes and stirring a resultant mixture, and (II) drying the plurality of glass flakes stirred with the liquid added thereto. Unlike conventional flaky-glass granules, the flaky-glass granules produced by this method contain neither a binder nor a surface treatment agent for bonding the glass flakes to each other. Thus, when mixed into a thermoplastic resin to be molded at a high temperature, the flaky-glass granules cause neither foam inclusion nor discoloration in a molded article of the resin.

    摘要: It is desired to form a flange and roller guide surfaces on each retainer of a self-aligning roller bearing easily and with high precision. Each punched retainer include a large-diameter annular portion (1), a small-diameter annular portion (2), a plurality of bridges (3) extending between the annular portions (1) and (2) and defining a plurality of circumferentially separated pockets (4) therebetween, roller guide surfaces (1a) that can be brought into sliding contact with end surfaces of respective convex rollers (5), which revolve around the axis of the bearing, and a flange (6) formed by radially bending the large-diameter annular portion (1). The roller guide surfaces (1a) comprise punched sections formed on the portions of the inner peripheries of the pockets (4) located at the large-diameter annular portion (1), and the flange (6) has a Bent Portion® that extends the entire circumference of the large-diameter annular portion (1). With this arrangement, the roller guide surfaces (1a) can be formed by punching only, which is a essential step. This makes it possible to make uniform the flatness of the back and front surfaces of the flange and its bent angle over the entire circumference thereof.

    摘要: In an information memory apparatus having minute areas for storing information arranged in x, y and z directions three-dimensionally, parallel rays are irradiated to a memory area MA in a direction perpendicular to a z-axis to take projection images of the memory area MA while rotating the memory area MA around the z-axis little by little. The light rays irradiated at this time have a size which covers at least a direction of an x-y plane of the memory area. A computation unit PU finds data and addresses of minute areas distributed three-dimensionally by performing computation based upon the principle of computer tomography on the projection images. As for data writing, a change is given to optical transmissivity or light emission characteristics by irradiating laser light focused by a lens OL placed outside the memory area to a desired minute area and causing heat denaturation within the pertinent minute area.
