  • Publication number: 20250054564
    Abstract: According to one embodiment, a memory system includes a memory chip and a memory controller. A first cell unit and a second cell unit are classified into a first group. A third cell unit is classified into a second group. The memory controller is configured to use a first correction amount of a read voltage when data of the first group is read and to use a second correction amount of the read voltage when data of the second group is read. When a time difference from a write operation of the first cell unit to the write operation of the second cell unit exceeds a reference value, the memory controller is configured to change a boundary position between the first group and the second group to between the first cell unit and the second cell unit, and to classify the second cell unit into the second group.

  • Publication number: 20250022498
    Abstract: A first circuit outputs first information indicating presence/absence of a magnetic wall between two adjacent portions among portions of a magnetic body, and second information based on the combination of magnetization states of the two portions. A first storage circuit stores first bits corresponding to the portions. A most significant bit of the first bits has a value independent of a magnetization state of a corresponding one of the portions, and the first bits have a value based on the first information. A second storage circuit stores the second information. The second circuit causes the first storage circuit to output the first bits when a value of a least significant bit of the first bits matches a value of the second information, and otherwise third bits having inverse values of the first bits.

  • Patent number: 12179495
    Abstract: Closing the replenishing solenoid valve Vl1 and opening the return solenoid valve Vl2 prohibits passage of the ink fed using the replenishing pump 951 through the replenishing solenoid valve Vl1 and allows this ink to pass through the return solenoid valve Vl2. In this way, the ink is circulated along the circulation path Cc2 (second circulation path) along which the ink is fed from the buffer tank 95a to the branch point J though the replenishing pipe 95b and then fed from the branch point J to the buffer tank 95a through the return pipe 961.

  • Patent number: 12157317
    Abstract: The ratio of the rotation speed Nr of the take-up roller (take-up rotation speed) and the rotation speed Nu of the feeding roller (feeding rotation speed) is used. That is, knowledge that the roll diameter Drr of the sheet S taken up on the take-up roller is given by a function using the ratio of the rotation speeds Nr and Nu as a variable was obtained. Accordingly, the roll diameter Drr is computed from this ratio.

  • Publication number: 20240379267
    Abstract: A superconducting wire includes: a superconductor laminate including a metal substrate and an oxide superconducting layer; and a stabilizing portion that covers the superconductor laminate and that has a thermal expansion coefficient larger than a thermal expansion coefficient of the metal substrate. The superconductor laminate has: a first main surface on which the oxide superconducting layer is disposed, and a second main surface on which the metal substrate is disposed. The stabilizing portion includes: a first portion facing the first main surface; and a second portion facing the second main surface. A thickness of the second portion is larger than a thickness of the first portion.

  • Patent number: 12138931
    Abstract: The cleaning liquid is supplied to the head facing flat surface, and the dummy flat surface of the dummy block facing the head facing flat surface contacts the cleaning liquid. This causes the cleaning liquid to be spread on the head facing flat surface by the dummy flat surface. The cleaning liquid spread on the head facing flat surface is sucked through the suction holes of the suction block. The suction holes can be cleaned by the cleaning liquid passing through the suction holes according to suction. On this occasion, the ink supplied to the head facing flat surface is removed through the suction holes of the suction block. The suction holes have both a function of removing the ink from the discharge heads H and a function of removing the cleaning liquid from the head facing flat surface.

  • Publication number: 20230398781
    Abstract: The present invention includes a head holder configured to collectively holding a plurality of discharge heads and a collective head mover configured to move the head holder between a printing space above the printing medium being conveyed in the conveying direction and a retraction space separated from the printing space. Therefore, is provided a printing technique capable of printing a high-quality image at low cost by discharging inks from a plurality of discharge heads arranged adjacent to each other in a direction parallel to a conveying direction of a printing medium while reciprocally moving the respective discharge heads between a printing space and a retraction space.
