  • Patent number: 8146840
    Abstract: An electrostatic painting method is disclosed in which air inside a paint feed channel is expelled when a color for painting is changed. An electrically conductive paint is channeled into a discharge channel of a fluid pathway, and the flow rate of the paint is measured. The fluid pathway is provided, via a paint valve, to a color changing valve mechanism, and communicates with a paint cartridge. The changing valve mechanism is provided in a distant position relative to a painting gun. Electrically conductive paint is channeled through a paint feed channel, which extends from the color changing valve mechanism to the painting gun, and air inside the paint feed channel is expelled. The paint feed channel is then filled with the electrically conductive paint according to the value measured for the flow rate.

  • Patent number: 8007872
    Abstract: An electrostatic coating method in which a coating material cartridge is used. When a coating material feeding path (68, 88) is cleaned by a liquid fed from a coating material feeding unit (20), the liquid is fed from the coating material feeding unit to a storage part (13) and stored. The liquid in the storage part is then fed to a fluid chamber (83) inside a coating material cartridge (19) via a fluid circuit (10A). The liquid in the fluid chamber pushes out the electrically conductive coating material inside a coating material chamber (84) via a free piston (82), and the electrically conductive coating material is fed to a coating gun (14).

  • Patent number: 7969429
    Abstract: The collector, emitter, and base of a bipolar transistor circuit are connected to a high side power supply terminal, the drain of a level shift transistor, and a floating power supply terminal, respectively. When a high side output transistor is on, the floating power supply terminal is at the potential of a high potential power supply terminal. The high side power supply terminal is at a potential higher than the potential of the floating power supply terminal by a constant voltage. Turning the level shift transistor on, its drain potential drops below the potential of the floating power supply terminal; The base current flows through the bipolar transistor circuit and the drain potential of the level shift transistor is clamped near the potential of the floating power supply terminal; The bipolar transistor circuit is turned on and its collector current supplies the drain current of the level shift transistor.

  • Publication number: 20100214197
    Abstract: In a row-electrode drive circuit of a PDP display device, an N-channel MOS low-side transistor of an output section is in an ON state while a light emission of a capacitive load is sustained. Now, if power to a driver section is lost due to, for example, a disconnection of a line from an external power supply to a low-voltage power terminal, this loss of power is detected by a detection section, and a current path via a parasitic diode of a P-channel MOS transistor, which has turned off, in the driver section to the low-voltage power terminal is interrupted. As a result, the N-channel MOS low-side transistor of the output section has the charged electric charge of the capacitive load stored in a parasitic capacity between its drain and gate, so maintains the ON state.
