The present invention provides a charging member comprising a support, a conductive elastic layer formed on the support, and a surface layer formed on the conductive elastic layer, characterized in that the surface layer contains a polysiloxane having a fluoroalkyl group and an oxyalkylene group, and a process cartridge and an electrophotographic apparatus having the charging member.Type: GrantFiled: September 1, 2005Date of Patent: June 14, 2011Assignee: Canon Kabushiki KaishaInventors: Noriaki Kuroda, Hisao Kato, Toshinari Miura, Toshiro Suzuki, Takumi Furukawa, Michitaka Kitahara, Jun Murata, Yukinori Nagata, Masaki Ozawa, Kazuyuki Shishitsuka, Yoko Kuruma

Patent number: 7944674Abstract: An electrode is provided that is adapted to both pierce a barrier and providing an over-air discharge of electrical energy. In this regard, an over air discharge of electrical energy may be provided to an opposing side of a barrier. In one arrangement, the electrode includes a tapered point, which may be a hardened material, to facilitate piercing a barrier. In a further arrangement, the electrode incorporates an insulative shaft. In this arrangement, the insulative shaft electrically isolates a conductor of the electrode from a conductive barrier. Accordingly, the electrode may be utilized to pierce metallic enclosures and provide an electrical discharge for the purpose of altering the operation of electronic device within such enclosures.Type: GrantFiled: March 24, 2006Date of Patent: May 17, 2011Assignee: Applied Energetics, Inc.Inventors: Stephen William McCahon, Paul Bryan Lundquist

Publication number: 20110090611Abstract: A particle charger with sheath air flow for enhancing charging efficiency includes a housing and a discharge wire. The housing has a charging chamber for accommodating the discharge wire, a particle inlet, a sheath air inlet, an outlet and an accelerating channel. A clean sheath air is guided through the sheath air inlet into the charging chamber to surround charged particles, reducing deposition of charged particles on the inside wall of the housing. A relatively small annular gap of accelerating channel accelerates the charged particles to exit the particle charger, and therefore minimized the particle electrostatic loss due to depositing on the inner surface of the housing. Additionally, uncharged particles approach the discharge wire axially, and charged particles move away radially. It is helpful for the charged particles to diffuse rapidly and uniformly, thereby enhancing the charging efficiency.Type: ApplicationFiled: December 29, 2009Publication date: April 21, 2011Applicant: NATIONAL CHIAO TUNG UNIVERSITYInventors: Chuen-Jinn Tsai, Lin Guan-Yu, Chen Hui-Lin

Publication number: 20110075316Abstract: A system for the recovery and use of the electrostatic charge present in the atmosphere during storms generated by lightning, transforming natural energy into electrical energy useful for consumption, and providing the necessary protection for lives and property against electro-atmospheric phenomena, has an ecological lightning conductor, an electrical conductor connected by one end to the low-frequency electrode of the lightning conductor, and an enhanced intelligent earth wire, whereto the conductor is joined by its other end. The conductor includes a series of probes and magnetic field detectors which will send information to the microprocessor and from there to the mainframe computer. The control device allows regulation of the earth resistance, thereby generating more or less charge, diverting the energy to the accumulators or to earth through dissipator electrodes.Type: ApplicationFiled: September 27, 2010Publication date: March 31, 2011Inventors: Angel Rodriguez Montes, Antonio Claveria Canal

Publication number: 20110019331Abstract: A power supply having an electrostatic circuit producing sufficient ionic motion to move ambient air over heated surfaces. The electrostatic circuit creates a corona discharge from several emitter point sources producing sufficient ionic motion to move ambient air over a hot surface, such as a heatsink or heatfins, which surface is in communication with the power supply housing. A high DC voltage is generated within the power supply when the power supply is energized to create the ionic motion.Type: ApplicationFiled: September 30, 2010Publication date: January 27, 2011Applicant: iGo, Inc.Inventor: Richard G.

Patent number: 7874503Abstract: An electrostatically atomizing device capable of instantly giving an electrostatically atomizing effect without requiring a water tank. The electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, a water feeder configured to give water on the emitter electrode, and a high voltage source configured to apply a high voltage across said emitter electrode and said opposed electrode to electrostatically charge the water on the emitter electrode for spraying charged minute water particles from a discharge end of the emitter electrode. The water feeder is configured to condense the water on the emitter electrode from within the surrounding air, enabling to supply the water on the emitter electrode in a short time without relying upon an additional water tank. Thus, an atomization of the charged minute water particles can be obtained immediately upon use of the device.Type: GrantFiled: April 1, 2005Date of Patent: January 25, 2011Assignee: Panasonic Electric Works Co., Ltd.Inventors: Osamu Imahori, Toshihisa Hirai, Kishiko Hirai, legal representative, Akihide Sugawa, Fumio Mihara, Shousuke Akisada, Tomoharu Watanabe, Hirokazu Yoshioka, Kentaro Kobayashi, Shinya Murase, Kouichi Hirai, Junji Imai
