To provide a method for quantitatively and stably feeding fine powder and a system for carrying out the method. The present invention is characterized in that a gas transfer type fine powder quantitative feeding method for quantitatively transferring and feeding fine powder filled in a gas transfer type fine powder quantitative feeder to a fine powder using device by a carrier gas, wherein when a mixed fluid of the fine powder and the carrier gas is transferred from the gas transfer type fine powder quantitative feeder to the fine powder using device, a water content in the carrier gas is adjusted to suppress an amount of static electricity that is generated in the mixed fluid.

Disclosed in some embodiments is a chamber component (such as an end effector body) coated with an ultrathin electrically-dissipative material to provide a dissipative path from the coating to the ground. The coating may be deposited via a chemical precursor deposition to provide a uniform, conformal, and porosity free coating in a cost effective manner. In an embodiment wherein the chamber component comprises an end effector body, the end effector body may further comprise replaceable contact pads for supporting a substrate and the contact surface of the contact pads head may also be coated with an electrically-dissipative material.

An electrostatic discharge tubing segment includes a porous non-conductive interior surface and an adjacent conductive polymer portion. The conductive polymer portion is configured to transfer electrostatic charge generated by a charged fluid passing through the tubing segment to ground such that electrostatic discharge can be mitigated.

Problem

All conductive bodies and particularly humans bodies, living in an electrified environment are traversed by alternating currents. Especially with the rise of electromobility, these currents are also present outside the typical house or office or factory environment, influencing the body almost during the whole 24 hours life cycle.

Solution

The invention proposes simple, contactless means to protect the body, by compensating the induced currents from the electrified environment. An isolated, intermediate conductive plate between the ground and the body is used to sense and minimize the induced currents. A coil at the periphery of the intermediate plate is used to sense and compensate the induced magnetic field, in its simplest embodiment
