  • Patent number: 10746352
    Abstract: A lubricant coating device preventing coating unevenness of lubricant powders is provided. The lubricant coating device includes a solid lubricant, a coating member and a film shaping member. The coating member in which first fibers composed of a material located on a positive polarity side and second fibers composed of a material located on a negative polarity side, on a triboelectric series with respect to the material of the solid lubricant are implanted, coats lubricant powders scraped off from the solid lubricant onto the image supporter. The film shaping member comes in contact with the image supporter and presses the lubricant powders onto the image supporter, to shape the lubricant powders into a form of a film. A scraping amount of the lubricant powders by the first fibers and a scraping amount of the lubricant powders by the second fibers are set to become substantially identical.

  • Patent number: 10381211
    Abstract: On field ionization under ambient conditions is described and applied on both ionization and desorption of various chemicals and biochemical present on the surface of materials in solid, liquid or gas states. The Atmospheric Pressure Megavolt Electrostatic Field Ionization Desorption (APME-FID) method generates ions directly from the surface of samples connected to a high electrical voltage at megavolt conditions. Megavolt electrostatic potential is generated and gradually accumulated directly on the sample surface by a Van de Graaff generator without causing damage to the sample. Therefore, when coupled with mass spectrometric system, the APME-FID-MS method enables direct detection of analytes on the surface of samples in different sizes and diverse types.

  • Patent number: 10300157
    Abstract: Described is a retail store fixture that includes an electric charge circuit. The electric charge circuit generates a positive electric charge, or voltage, in response to the motion of a moveable portion of the retail store fixture. The retail store fixture can be a shopping cart or other fixture with a moveable portion. The positive electric charge is deposited on a part of the retail store fixture that it is desired to sterilize. The positive electric charge repels bacteria, sterilizing the portion of the retail store fixture that receives the positive charge. A shopping cart, for example, equipped with the electric charge circuit can be sterilized without requiring chemicals or power to be supplied to the cart. Rotation of the shopping cart wheels can be used to generate the voltage. The voltage can be used to sterilize a shopping cart handle, and/or other parts of the shopping cart.

  • Publication number: 20140150816
    Abstract: Various embodiments herein include at least one of systems, methods, and software to facilitate automatic solar power surface-cleaning. Such embodiments include at least one automatic solar power surface-cleaning robot that uses no water or external power, continuously cleans the solar power surfaces and requires no maintenance or external power. The solar power surface-cleaning robot is easy to retrofit in an existing solar power generation plant. An automatic solar power surface-cleaner uses high-voltage AC electric fields to sweep particulates and debris as the robot traverses the surface to be cleaned. Photovoltaic solar cells supply the power for the robot. No external power is required. The robot clamps to the surface to be cleaned at the edges using motor driven rollers. Electronics inside the device generate high-voltage AC that is applied to conductors close to the surface to be cleaned.

  • Publication number: 20140048098
    Abstract: An active electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere dust or other foreign objects against an interactive surface, from which the foreign objects are removed when the forces are controllably altered. User inputs control the input voltage and/or designate the size of foreign objects to be cleaned. An active power source provides the input voltage, and the interactive surface can be a continuous track across one or more rollers to move the device across a dirty foreign surface. Electrodes can be arranged in an interdigitated pattern having differing pitches that can be actuated selectively to clean foreign objects of different sizes. Sensors can detect the amount of foreign particles adhered to the interactive surface, and reversed polarity pulses can help repel items away from the interactive surface in a timely and controlled manner.

  • Patent number: 8627531
    Abstract: When the electrically driven fan (14) of a vacuum cleaner is driven, air containing dust is drawn into the cleaner main body (1) through a hose (7) connected to a hose socket (8) and is exhausted into the outside of the cleaner main body (1) through an exhaust port (1b) via first and second suction passageways (10, 13). Disposed outside the first suction passageway (10) is an ion generator (23), it being arranged that plus and minus ions generated in the ion generator (23) are fed to the air stream flowing in the first suction passageway (10). Since the plus and minus ions kill floating germs in the air stream, the exhaust can be purified.

  • Publication number: 20130263393
    Abstract: A transparent electrodynamic screen (EDS) enables automatic removal of dust to protect and enhance performance of solar collectors and similar components. A pattern of transparent conductive electrodes are deposited over a glass or polymer outer surface of a solar collector, and embedded under a thin, transparent dielectric fluoropolymer film or silicon dioxide coating. When energized by three-phase voltages at frequencies in the range 5 to 20 Hz, the electrodes produce an oscillating electric field and a traveling electrodynamic wave that charges the particles on the surface and exerts coulomb and dielectrophoretic forces to lift the dust from the surface and transport it to an edge of the collector, thereby clearing the screen. The EDS can be incorporated in the collector in an integrated way during manufacture or retrofitted to existing conventional collectors.
