  • Patent number: 7402456
    Abstract: A method is provided for forming a Pr0.3Ca0.7MnO3 (PCMO) thin film with crystalline structure-related memory resistance properties. The method comprises: forming a PCMO thin film with a first crystalline structure; and, changing the resistance state of the PCMO film using pulse polarities responsive to the first crystalline structure. In one aspect the first crystalline structure is either amorphous or a weak-crystalline. Then, the resistance state of the PCMO film is changed in response to unipolar pulses. In another aspect, the PCMO thin film has either a polycrystalline structure. Then, the resistance state of the PCMO film changes in response to bipolar pulses.

  • Publication number: 20080170481
    Abstract: An aberration detection device of the present invention is such that an absolute value of detection sensitivity of an aberration error signal is increased, and variation in detection sensitivity of the aberration error signal is little even when displacement between the center of light beam dividing means and the center of a bundle of light beams occurs due to a shift of a condensing optical system at the time of tracking control. A hologram element (2) divides light beams reflected from an information storage medium into at least two positive first order diffracted light beams. The hologram element (2) has a line (D1) extending in a radial direction and passing through an optical axis (OZ) and a division line (D2) having segments at least both ends thereof and a bulge in a center thereof, wherein the segments are substantially parallel to the line (D1), and the bulge (44) bulges toward the periphery of the hologram element (2) so that a top (D5) of the bulge (44) is substantially parallel to the line (D1).

  • Patent number: 7400063
    Abstract: The switched-mode power supply includes an output value sensor circuit measuring a current flow through a switching device and a switching control circuit implementing overcurrent protection. Also included in the power supply are: a second output voltage sensor circuit detecting a high output voltage for the second load; and a short-circuit device quasi-shorting the terminals of the second load when the detected value of the voltage is more than or equal to a specific value. Therefore, if the short-circuit device shorts out, the secondary load increases, and the output for the relatively low load can be restrained by overcurrent protection. Thus, a reliable overcurrent protection can be achieved using a simple construction by means of cross-regulation.

  • Patent number: 7400126
    Abstract: In a DC regulated power supply realized as AC adapter or the like by a switching power supply, a reference voltage correction circuit, which estimates a voltage drop corresponding to a load current, corrects to increase an output voltage by changing a feedback reference value for regulation of the output voltage from a reference voltage source, in accordance with the load current sensed by the load current sensing circuit. Therefore, there occurs no negative effects that would be caused when output sensing wires are routed to a remote load. In addition, unlike the arrangement in which a reference-use rectifying circuit as well as a load-use rectifying circuit are provided, the arrangement of the switching power supply is not complicated. That is, in correcting a voltage drop, which occurs in power supply lines, corresponding to the load current, it is possible to easily perform a stable output voltage control unaffected by wire routing.
