Latest Patents

One of Ota's latest patents focuses on an electrostatic coater and an electrostatic coating method. This innovation addresses the issue of charge remaining in an electrostatic coater when the power supply is stopped. The design includes a rotary atomizing head that receives a high voltage of negative polarity from a cascade. Additionally, the electrostatic coater features a second high-voltage generator that produces a high voltage of positive polarity. This generator is composed of a Cockcroft-Walton circuit, which utilizes diodes and capacitors. The high voltage is controlled by a controller, ensuring that immediately after the electrostatic coater is stopped, power is supplied to the second high-voltage generator. This allows the positive voltage to be supplied to the rotary atomizing head for a predetermined time period, effectively neutralizing the charge.
