  • Patent number: 11207052
    Abstract: To reduce noise which leaks to the outside in an ultrasonic diagnostic apparatus. An internal AC wiring unit 34 is composed of internal AC wiring which is installed on the input side of a power source circuit, and a shield case 38 which accommodates it. The internal AC wiring includes an inlet, a plurality of connectors, a relay substrate, and a plurality of internal AC cables. The internal AC wiring is protected from radiation noise which is generated in a casing 22 by the shield case 38. Thereby, the noise which leaks to the outside via an external AC cable is reduced.

  • Publication number: 20210384206
    Abstract: A three-dimensional memory device can include at least one alternating stack of insulating layers and electrically conductive layers located over a semiconductor material layer, memory stack structures vertically extending through the at least one alternating stack, and a vertical stack of dielectric plates interlaced with laterally extending portions of the insulating layers of the at least one alternating stack. A conductive via structure can vertically extend through each dielectric plate and the insulating layers, and can contact an underlying metal interconnect structure. Additionally or alternatively, support pillar structures can vertically extend through the vertical stack of dielectric plates and into an opening through the semiconductor material layer, and can contact lower-level dielectric material layers embedding the underlying metal interconnect structure to enhance structural support to the three-dimensional memory device during manufacture.

  • Publication number: 20210366808
    Abstract: A first-tier structure includes a first vertically alternating sequence of first continuous insulating layers and first continuous sacrificial material layers and a first-tier retro-stepped dielectric material portion overlying first stepped surfaces of the first vertically alternating sequence. A second vertically alternating sequence of second continuous insulating layers and second continuous sacrificial material layers is formed over the first-tier structure. Retro-stepped dielectric material portions are formed in each of the first-tier structure and the second-tier structure. After formation of memory stack structures, electrically conductive layers replace portions of the first and second continuous sacrificial material layers. Laterally-isolated contact via structures can be formed through the second-tier structure and a first-tier retro-stepped dielectric material portion on first electrically conductive layers in the first-tier structure.

  • Patent number: 11144189
    Abstract: An apparatus and method for moving thumbnails on a screen is provided. In a case where thumbnails desired by a user among a displayed list of thumbnails are moved by a drag-and-drop operation, if the number of thumbnails as movement targets is large, it takes time to perform a selection operation. Where one of a plurality of thumbnails displayed as a list is dragged and dropped by a user, based on a drop position, a thumbnail group including the dragged thumbnail and thumbnails positioned on a first side of the dragged thumbnail or on a second side, opposite the first side, of the dragged thumbnail among the displayed list of thumbnails is determined as a movement target for subsequent movement thereof.

The control device has a rotation speed calculation unit that calculates a rotation speed of a motor; an optimum voltage calculation unit that calculates an optimum input voltage; a minimum voltage calculation unit that calculates a minimum input voltage required to operate the motor at a motor operating point; and a target value setting unit that sets either one of the optimum input voltage and the minimum input voltage as a target input voltage. In a case in which the set target torque exceeds a predetermined value, the target value setting unit sets the minimum input voltage lower than the optimum input voltage as the target input voltage.
