Patent number: 9674934Abstract: Provided is an ion generator that has a potential sensor provided integrally inside the main body of the ion generator, and that can measure, with the potential sensor, an electric field that reaches the potential sensor from a member from which static charge is to be eliminated, without being affected by an electric field between a discharge electrode and an opposing electrode. This ion generator comprises a discharge electrode, an opposing electrode, and a main body part including these electrodes, the ion generator sending out, toward a member from which static charge is to be eliminated, air ions generated by applying a high voltage between the electrodes.Type: GrantFiled: April 9, 2014Date of Patent: June 6, 2017Assignee: KOGANEI CORPORATIONInventors: Yoshinari Fukada, Kazuyoshi Onezawa

Patent number: 8355237Abstract: A maintenance operation of an ion generator can be easily performed. A device main body has an inner case and an outer case, and the inner case having a support block and an air supply pipe is inserted into the outer case. An opposite electrode is detachably mounted in the support block from a front side of the device main body, and a discharge needle unit is detachably mounted from a reversed direction thereto. The discharge needle unit has a holder, in which the discharge electrode is provided, and a sleeve, which forms an ion generating space between the opposite electrode and the sleeve, is detachably mounted in the holder. Air supplied from an outside is supplied to the ion generating space via a flow path in the air supply pipe.Type: GrantFiled: February 14, 2011Date of Patent: January 15, 2013Assignee: Koganei CorporationInventors: Kazuo Kotsuji, Kazuyoshi Onezawa, Yoshinari Fukada, Akira Goto

Patent number: 8035948Abstract: This static eliminator is used for eliminating static electricity from an object by ionizing the air to be blown to a charged object, and has a case 12 body provided with an air blow duct 15 for blowing out an ionized air, and an electric discharge module 27 being mounted detachably on the case body 12. The electric discharge module 27 has an electric discharge needle substrate 31 having a plurality of electric discharge needles 38 arranged straightly, and a surface panel 32 detachably mounted on the case body, and the electric discharge module 27 is mounted on the case body 12 by mean of a mounting screw member 36 in the portion of the surface panel 12. By dismounting the electric discharge module 27 from the case body 12, the electric discharge needles can be replaced.Type: GrantFiled: April 11, 2007Date of Patent: October 11, 2011Assignee: Koganei CorporationInventors: Kazuyoshi Onezawa, Yoshinari Fukada, Yosuke Enomoto

Patent number: 7561403Abstract: A static eliminator capable of replacing a discharge needle and improving maintainability of the eliminator is disclosed. The static eliminator comprises: an air-guiding duct having a tubular portion provided with an outer electrode and a boss portion; and an electric discharge module detachably mounted on the tubular portion, wherein ionized air is supplied to the air-guiding duct by a fan of an air blower. The electric discharge module has a holder fitted in a boss portion and a plurality of discharge electrodes attached to the holder so as to protrude toward the outer electrode in an outer-radial direction. When foreign substances or the like adhere to a tip of the discharge electrode or when the discharge electrode deteriorates, the electric discharge module is detached from the boss portion.Type: GrantFiled: January 13, 2006Date of Patent: July 14, 2009Assignees: Koganei Corporation, Shishido Electrostatic, Ltd.Inventors: Kazuyoshi Onezawa, Yoshinari Fukada, Yosuke Enomoto
