  • Patent number: 11330995
    Abstract: The present invention images a heartbeat strength representing the strength of pulsations (beats) on a map as a new dynamics index different from the conventional waveform numerical value. A computation section according to the present invention obtains, from time-course changes of the blood flow map obtained as a result of computation of blood flow speed, a signal intensity at a fundamental frequency determined from time-series blood flow data within a predetermined region, and calculates a heartbeat strength which represents the strength of heartbeats on the basis of the signal intensity. A display section images and displays the heartbeat strength calculated by the heartbeat strength computation section. Also, the display section displays the heartbeat strength calculated by the heartbeat strength computation section by superimposing the heartbeat strength on a combined map created by averaging a plurality of blood flow maps arranged in a chronological order.

  • Patent number: 11135605
    Abstract: A charge remaining in an electrostatic coater when power supply to the electrostatic coater is stopped is neutralized at an early stage. A rotary atomizing head 102 receives a high voltage of negative polarity from a cascade 104. An electrostatic coater 100 further includes a second high-voltage generator 110 that generates a high voltage of positive polarity. The second high-voltage generator 110 is composed of a Cockcroft-Walton circuit. The Cockcroft-Walton circuit is composed of diodes and capacitors. A high voltage of the electrostatic coater 100 is controlled by a controller 10. Immediately after running of the electrostatic coater 100 is stopped by stopping power supply to the cascade 104, power is supplied to the second high-voltage generator 110. The high voltage of positive polarity generated by the second high-voltage generator 110 is supplied to the rotary atomizing head 102 for a predetermined time period.
