Abstract: A non-volatile semiconductor memory device includes: a memory cell array in which a plurality of electrically rewritable and non-volatile memory cells are arranged; a sense amplifier circuit configured to write M-value data (where, M is an integer equal to 4 or more) to pair-cells each constituted by simultaneously selected first and second memory cells connected to a pair of bit lines in the memory cell array, the M-value data being defined as a combination of different threshold levels of the first and second memory cells in M threshold levels to be set at each memory cell, and read M-value data stored in each pair-cell by sensing a difference between cell currents of the first and second memory cells: and a controller configured to control data write and read operations for the memory cell array.

Abstract: A single crystal pulling device is composed of a cylindrical pulling furnace, a crucible disposed in the pulling furnace in which a single crystal material for a semiconductor is poured, a cylindrical vacuum vessel coaxially disposed around the pulling furnace, and a superconducting magnet composed of a plurality pairs of coils arranged inside the vacuum vessel so as to generate magnetic field. The superconducting coils are arranged on the same horizontal plane of the cylindrical vacuum vessel, and each of the paired superconducting coils includes coils set so as to oppose to each other with respect to a central axis of the cylindrical vacuum vessel so that one coil of one pair of coils and one coil of another pair of coils adjacent to that one pair of coils constitutes a set angle, directing towards the inside of the cylindrical vessel, in a range of 100° to 130°.

Abstract: An ultrasound diagnosis apparatus comprises an insonifier, a receiver, and a processor. The insonifier is configured to insonify an ultrasound to a specimen. The receiver is configured to receive an echo signal from the specimen resulting from the ultrasound. The processor is in communication with the receiver. Further, the processor is configured to process the echo signal so as to obtain a first series of images under a first condition and a second series of images under a second condition. The processor is also configured to measure a first physical value on the first series of images and a second physical value on the second series of images. The processor is further configured to adjust a time phase of the second series of images relative to a time phase of the first series of images based on the first physical value and the second physical value.

Abstract: An information recording and reproduction apparatus comprising a recording and reproduction section configured to record and reproduce information in and from one recording medium of a first group and at least one recording medium of a second group, which has a smaller recording capacity than the one recording medium of the first group, and a registering section configured to reserve, in the one recording medium of the first group, a recording region which corresponds to the recording capacity of the at least one recording medium of the second group.

Abstract: A magnetic field sensor has a pair of magnetic shields serving as a negative electrode and a positive electrode, respectively, a magnetoresistive element arranged between the pair of magnetic shields, a nonmagnetic conductive layer for the negative electrode arranged between the magnetic shield for the negative electrode and the magnetoresistive element and including a first metal layer formed in contact with the magnetoresistive element and a second metal layer formed in contact with the first metal layer, and a nonmagnetic conductive layer for the positive electrode arranged between the magnetic shield for the positive electrode and the magnetoresistive element and formed of a first metal layer, the first metal layer containing at least one metal selected from the group consisting of Ta, Ti, Cr, V, Mo and W.

Abstract: Disclosed is a method of adding a compound having at least one group selected from the group consisting of a carboxyl group, salts thereof, esters thereof and haloformyl groups or an acid anhydride, as a treating agent, to a resin decomposed substance prepared by decomposing a urethane bond of a urethane resin, and adding an epoxy resin or isocyanate compound to the product, to regenerate the resin. According to the present invention, reaction activity in producing a regenerated resin from a urethane resin decomposed substance is appropriately suppressed, and thus regeneration of a urethane resin can be carried out by easy procedures.
