Patent number: 8506780Abstract: A gas sensor includes an internal space, diffusion control part, pumping cell, and measuring cell. The diffusion control part communicates with the internal space and has a slit-like shape with a smaller thickness than that of the internal space. The pumping cell pumps out oxygen from the internal space when voltage is applied between a first electrode fowled on a surface of the internal space and a second electrode formed outside the internal space. The measuring cell measures a current flowing between a third and fourth electrodes when a voltage is applied between the third and fourth electrodes. The third electrode is formed in the diffusion control part, and can reduce an oxide gas component in a predetermined gas component to which a predetermined diffusion resistance has been applied by the diffusion control part. The fourth electrode is formed in a part different from the diffusion control part.Type: GrantFiled: October 12, 2010Date of Patent: August 13, 2013Assignee: NGK Insulators, Ltd.Inventors: Mika Murakami, Hiroki Fujita, Sumiko Horisaka, Takashi Ito, Sang Jae Lee

Patent number: 8464573Abstract: A flow path from outer gas introduction apertures 144a to inner gas introduction apertures 134a has a narrower-width flow passage formed by an inner wall member 150. This structure effectively lowers the probability that a liquid, such as water, entering from the outer gas introduction apertures 144a passes through a gas inflow chamber 122 and reaches a sensor element 110, compared with a structure without the inner wall member 150. The inner wall member 150 is formed as a solid member that is capable of storing the surrounding heat. Even if there is a certain event that has the potential of causing a temperature decrease of the sensor element 110, for example, an abrupt change in flow rate of an object gas, the heat stored in the inner wall member 150 effectively prevents a temperature decrease of the sensor element 110. This structure prevents the occurrence of cracking in the sensor element 110, compared with a conventional sensor structure having a double-layered protective cover.Type: GrantFiled: November 29, 2010Date of Patent: June 18, 2013Assignee: NGK Insulators, Ltd.Inventors: Takayuki Sekiya, Kei Kosaka, Sang Jae Lee

Patent number: 8409414Abstract: A gas sensor and nitrogen oxide sensor, which, when fitted to the exhaust system of an internal combustion engine, can suppress the influence of harmful substances contained in a measurement gas and can prevent the reduction in sensitivity over time. A harmful substance-trapping layer is formed at a gas inlet for introducing a to-be-measured gas from an external space into an internal space, and in a buffering space formed between diffusion resistance portions. In a trap-formed portion of a gas passage in which the harmful substance-trapping layer is formed, the measurement gas can pass in an amount of 80% or more of when the harmful substance-trapping layer is not formed in the trap-formed portion. A diffusion resistance is attained in the diffusion resistance portions; a harmful substance is trapped in the harmful substance-trapping layer; and the measurement gas is allowed to flow into a detection electrode side.Type: GrantFiled: January 7, 2009Date of Patent: April 2, 2013Assignee: NGK Insulators, Ltd.Inventors: Takeya Miyashita, Sang Jae Lee, Kunihiko Nakagaki
