  • Patent number: 10624606
    Abstract: An ultrasound diagnostic apparatus according to a present embodiment includes driving pulse generating circuitries and a transmission control circuitry. The transmission control circuitry turns on a switching element of respective driving pulse generating circuitries of the driving pulse generating circuitries to be grounded, and thereby controls so as to make an output impedance of the respective driving pulse generating circuitries become a low impedance. The transmission control circuitry turns off the switching element of the respective driving pulse generating circuitries, and thereby controls so as to make the output impedance become a high impedance by means of a resistance value of the resistance.

  • Patent number: 10529306
    Abstract: Pivot shaft support members, formed as component parts separate from support posts of a frame of a pedal apparatus, are mounted on respective upper ends of the support posts, and the pivot shaft support members pivotably support the opposite ends of a pivot shaft for a beater rod. A heel section is provided on a rear end portion of an under plate of the pedal apparatus, and a pair of left and right hinge support members, formed as component parts separate from the heel section, are mounted to the heel section. The hinge support members pivotably support the opposite ends of a pivot shaft of a hinge section of a foot board. Because the pivot shaft support members and the hinge support members are separate component parts from the frame, mounted positions of these support members can be adjusted finely during mounting, to the frame, of the support members.

  • Publication number: 20190272952
    Abstract: A magnetic core includes a winding core and first and second flanges connected to the winding core. First and second terminal electrodes are connected to a lead frame. The first flange is bonded to the first and second terminal electrodes. Third and fourth terminal electrodes are bonded to the second flange. First and second insulation-coated conductive wires are wound about the winding core. The first and second insulation-coated conductive wires are connected to the first and second terminal electrodes and the third and fourth terminal electrodes. The lead frame is bent so as to rotate the magnetic core by 90 degrees with respect to the lead frame. A magnetic plate is bonded to the magnetic core. The magnetic core is removed from the lead frame by removing the first and second terminal electrodes from the lead frame, thereby providing a common-mode choke coil. The common-mode choke coil having stable electrical performance is produced efficiently by the above method.

  • Publication number: 20180368806
    Abstract: According to one embodiment, the ultrasonic diagnostic apparatus includes a main body housing, an arm, a device, a table, and an avoiding mechanism. The arm is mounted to the main body housing so as to be capable of ascending and descending and pivotable about a predetermined axis. The device is supported by the arm so as to be capable of ascending and descending and pivotable according to the movement of the arm. The table has a surface which is positioned in a descending direction of the arm and the device, and an object is placed on the surface. The avoiding mechanism changes a relative position between the object and a support position of ascending and descending movement of the arm such that interference between the object and at least one of the arm and the device due to the descending movement of the arm is avoided.
