  • Patent number: 10323168
    Abstract: A production process for a crystal oriented ceramics includes: a first step of preparing composite particles formed of particles having magnetic anisotropy having magnetic susceptibility anisotropy and seed particles having magnetic susceptibility anisotropy less than or equal to 1/10 of the magnetic susceptibility anisotropy of the particles having magnetic anisotropy and are formed of an inorganic compound having an anisotropic shape in which a crystal axis intended to be corresponds to a minor axis or a major axis; a second step of adding raw material powder including the composite particles to a solvent to prepare a slurry a third step of preparing a green compact by disposing the slurry in a static magnetic field of ?0.1 tesla and drying the slurry in a state in which crystal axes of the seed particles in a major axis direction are in one direction; and a fourth step of sintering the green compact.

  • Patent number: 10049740
    Abstract: A memory circuit includes: cells arranged in rows and columns so that the rows are grouped to form banks each including one or more rows, each cell including: a bistable circuit storing data; and a non-volatile element storing data stored in the bistable circuit in a non-volatile manner and restoring data stored in a non-volatile manner to the bistable circuit; and a controller that performs a store operation on each row in turn; sets a voltage supplied, as a power-supply voltage, to cells in a first bank, which includes a row on which the store operation is performed, of the banks to a first voltage; and sets a voltage supplied, as a power-supply voltage, to cells in a bank of the banks other than the first bank to a second voltage that is less than the first voltage but at which data in the bistable circuit is retained.

  • Patent number: 9797059
    Abstract: A method for manufacturing a mold includes (a) anodizing an aluminum substrate at a voltage of 60 V to 120 V in an electrolytic solution in which two or more species of acid are mixed, and forming an oxide film having a plurality of minute holes on a surface of the aluminum substrate; and (b) removing at least a portion of the oxide film. The electrolytic solution used in (a) satisfies the relation (D1)/2<D2, where D1 is the current density when the aluminum substrate is anodized under the same conditions as in (a) in an electrolytic solution of only the acid (A) having the highest acid dissociation constant (Ka) of the two or more species of acid, and D2 is the current density when the aluminum substrate is anodized under the same conditions (a) in the same electrolytic solution as that of (a).
