Patent number: 8610355Abstract: A distance from a negative output terminal of a secondary winding of the transformer to a feeding terminal of the cathode plate is longer than a distance from a positive output terminal of the secondary winding to a feeding terminal of the anode. The anode side feeding path electrically connects the feeding terminal of the anode bar to the positive output terminal of the secondary winding. The cathode side feeding path electrically connects the feeding terminal of the cathode plate to the negative output terminal of the secondary winding. A path length of the cathode side feeding path is longer than a path length of the anode side feeding path. The housing is formed by an electric conductor and is electrically connected to the cathode side feeding path.Type: GrantFiled: August 17, 2012Date of Patent: December 17, 2013Assignee: NGK Insulators, Ltd.Inventors: Tatsuya Terazawa, Wataru Shionoya

Patent number: 8545765Abstract: A first electrode, a second electrode and a third electrode are provided in a middle of a passage. The second electrode is provided on an upstream side of the first electrode, and the third electrode is provided on a downstream side of the first electrode. A connecting line connects the first electrode to a first pole of a pulsed power supply, and connects the second electrode and the third electrode to a second pole of the pulsed power supply. The first electrode crosses a first gas passing surface and occupies a part of the first gas passing surface. The second electrode and the third electrode cross a second gas passing surface and a third gas passing surface and occupy a part of the second gas passing surface and the third gas passing surface respectively.Type: GrantFiled: April 19, 2012Date of Patent: October 1, 2013Assignee: NGK Insulators, Ltd.Inventors: Wataru Shionoya, Naohiro Shimizu, Yuichiro Imanishi, Sozaburo Hotta

Publication number: 20120048250Abstract: An electrode structure for a combustion vessel including a first electrode and a first dielectric barrier. The first electrode is made of a conductive material, has a rod-like shape, and protrudes from an inner surface of the combustion vessel. The first dielectric barrier is made of a dielectric material. The first electrode has, on its surface, a first exposed surface exposed in the combustion space and a first coated surface coated with the first dielectric barrier. A predischarge progresses while the first coated surface serves as a start point or an end point of the progress. A main discharge progresses while the first exposed surface serves as a start point or an end point of the progress. The main discharge includes a creeping discharge that creeps along a surface of the first dielectric barrier, and goes through a spatial region where the predischarge occurs.Type: ApplicationFiled: July 22, 2011Publication date: March 1, 2012Applicant: NGK Insulators, Ltd.Inventors: Kenjirou SHIMODA, Wataru Shionoya

Patent number: 7998608Abstract: A lithium secondary battery including: an inner electrode member having electrode plates (cathode plate and anode plate) of a metal foil as a constituting element, and being formed by winding or laminating electrode plates; and a battery case for housing the inner electrode member. A gas release channel capable of releasing a gas to the outside of the battery case is formed by deformation of the inner electrode member by a function of a raised inner pressure when the inner pressure of the battery case rises to a predetermined pressure or more due to the gas generated inside the inner electrode member. The lithium secondary battery can smoothly release the gas generated inside the inner electrode member without being retained therein before the gas reaches a pressure releasing mechanism; thus, it is superior in safety and has a high energy density.Type: GrantFiled: September 19, 2005Date of Patent: August 16, 2011Assignee: NGK Insulators, Ltd.Inventors: Tsutomu Mori, Wataru Shionoya, Shinji Ohtsubo, Kenshin Kitou
