An electrostatic spray painting apparatus includes an electrically-insulated intermediate reservoir for storing therein conductive paint to which a high voltage is directly applied. In addition, the intermediate reservoir includes a cylinder, a piston reciprocatively and slidably disposed within the cylinder, and a fluid-flow straightening member protrudently formed in a part of a cylinder chamber used to be charged with the paint. The cylinder chamber is defined by the cylinder and the piston. An injection hole is defined near an outer peripheral edge of a cylinder wall so as to be connected to a paint and cleaning fluid feed source. A discharge hole is centrally defined in the cylinder wall so as to be connected to a spray gun, the discharge hole being used to discharge the paint and the cleaning liquid.

An installation particularly suited to use in the automobile industry for electrostatic application of conductive coating product is partly at a high-tension voltage and partly grounded, these parts being separated by at least one temporary insulating device. The electrostatic sprayer is fed from a first storage tank insulated from ground and the latter is filled in a very short time period with coating product previously stored in a grounded second storage tank, through a temporary insulating device.

A sprayer installation suitable for spraying water-based paint includes a multi-axis robot carrying a sprayer. A conveyor carries objects to be sprayed past the robot. Respective circuits for distributing products to be sprayed comprise first connection devices at fixed locations within range of the robot. The robot carries a storage tank for the product to be sprayed at least during a spraying phase. This storage tank is connected to the sprayer to supply product to be sprayed to it. First complementary connection devices fitted to or communicating with the storage tank cooperate with the first connection devices of any selected distribution circuit.

A fluid dispensing device includes an electrostatic discharge protection system. Accumulation and discharge of electrostatic energy created by operation of the device is reduced or prevented by the electrostatic discharge protection system without an earth ground connection. The electrostatic discharge protection system may include a number of features, such as a static wick, nonconductive components that electrically isolate the spray tip of the device, nonconductive isolation barriers, nonconductive fluid reservoir and suction tube components, a nonconductive coating of a control valve component, and a nonconductive spring retainer of the control valve.

An electrostatic painting apparatus includes a painting gun having at one end thereof a paint spray section, and a connection section detachably connectable to an external paint supply section for receiving a supply of paint from the supply section and supplying the received paint to a paint storage section that stores and supplies the supplied paint to the painting gun. The connection section is surrounded and protected by a peripheral wall, so that paint can pass by the other end of the painting gun without reaching the connection section. Consequently, the connection section can be prevented from being undesirably smeared with the paint.

A method of manufacturing a ferroelectric thin film on a lower electrode by electrostatically spraying a ferroelectric thin film-forming electrostatic spray solution so as to coat the electrostatic spray solution on the lower electrode and form a coated film, drying, calcining, and then firing the coated film so as to crystallize the coated film. In this method, the electrostatic spray solution is a mixed solution in which a ferroelectric thin film-forming sol-gel solution and powder having the same composition as the solid content of the sol-gel solution and having a particle diameter that can be ejected from the spout are uniformly mixed, and, when the metallic compound-converted mass of a metallic compound dissolved in the sol-gel solution is represented by A and the mass of the powder is represented by B, a ratio of B with respect to (A+B) is in a range of 5% to 40%.
