Abstract:
A method of detecting a wire break in a high voltage generating device that is configured to detect a wire breakage in a low-voltage cable is disclosed. The method of a wire break includes: detecting whether a wire break has occurred in each of the lines in accordance with a combination pattern of whether the time differential value of an IM signal value of a CW circuit obtained when an operating voltage is boosted is positive, negative, or 0, and whether the time differential value of a VM signal value obtained after the operating voltage is boosted by the CW circuit is positive, negative, or 0; and identifying which of the lines is broken.

Abstract:
In an immobilization process of electrostatically spraying a nanomaterial dispersion liquid 13 from an electrostatic spray nozzle 20 and immobilizing a nanomaterial on a sample 10, a voltage is applied between the dispersion liquid 13 and the sample 10 to electrostatically spray the dispersion liquid 13 onto the sample 10 from a spray outlet 22 of the nozzle 20 under a condition where one or zero particles of the nanomaterial 18 are contained in each individual droplet 16 sprayed and electrostatically deposit the nanomaterial 18 onto a surface of the sample 10 after drying a solvent 17, contained in each individual droplet 16, in an atmosphere to immobilize the nanomaterial 18 on the sample 10. Aggregation of the nanomaterial in each droplet is thereby prevented and the nanomaterial can be immobilized favorably on the sample.

Abstract:
Disclosed is an electrostatic atomizer, which comprises a high-voltage applying section adapted to apply a high voltage between an atomizing electrode and a counter electrode so as to electrostatically atomize water supplied onto the atomizing electrode, wherein the high-voltage applying section is operable to set an absolute value of a voltage to be applied to the atomizing electrode smaller than an absolute value of a voltage to be applied to the counter electrode. This allows a physical object, such as an article stored in a mist-receiving space or an inner wall of a structural member defining the mist-receiving space to become less likely to be electrostatically charged, and makes it possible to avoid causing a problem about discomfort due to discharge of static charges when a user touches the physical object.
Abstract:
An electrostatic coating apparatus for coating an object includes a base module, a nozzle, an electric field generator and a power supply. The object is mounted on the base module. The nozzle receives gas and liquid and ejects the gas and the liquid. The electric field generator mounted on the base module generates an electric field. The power supply has a first pole electrically connected to a first pole of the electric field generator, and a second pole electrically connected to the object and a second pole of the electric field generator such that the electric field is generated in the electric field generator and the atomized liquid passing through the electric field generator is charged and absorbed onto the object to form a coating layer on the object.
Abstract:
An apparatus for applying electrostatic powders on manufactured articles, comprising at least one dispensing device adapted to dispense gas solid particles mixture having an electrostatic charge, and connected to at least one duct arranged proximate to the surface to be treated and defining a channel for conveying the mixture. The duct has laterally, along its longitudinal extension, at least one passage opening directed toward the surface to be treated. A partition is arranged with at least one of its portions substantially at the passage opening and is permeable to the powder particles. The passage opening and the partition are crossed by force lines of a first electrical field adapted to cause transfer of the powder particles transiting along the conveyance channel on the surface to be treated through the passage opening and the partition.
Abstract:
To provide a (homogeneous) particle deposit without any impurity contamination, on which only particles with a desired size are deposited. A solution, with particles dispersed in a solvent, is jetted as a flow of fine liquid droplets from a tip part of a capillary, and the jetted fine liquid droplets are electrically charged. This flow of the droplets is introduced into a vacuum chamber through a jet nozzle, as a free jet flow. The free jet flow that travels in the vacuum chamber is introduced into an inside of a deposition chamber, inside of which is set at lower pressure, through a skimmer nozzle provided in the deposition chamber, as an ion beam. Subsequently, by an energy separation device, only particles having particular energy are selected from the electrically charged particles in the flow, and are deposited on a deposited body disposed in an inside of the deposition chamber.
