During the pumping back operation, an NOX concentration correspondence value has a large time course change and is not stable. The NOX concentration correspondence value is corrected using correction data common among gas sensors, wherein the timing for applying the correction data is adjusted by making use of an application time determined in accordance with individual differences of each gas sensor.Type: ApplicationFiled: March 13, 2012Publication date: September 20, 2012Applicant: NGK SPARK PLUG CO., LTDInventors: Hirotaka ONOGI, Kenji KATO, Satoshi TERAMOTO

Publication number: 20120211374Abstract: An apparatus and method for individually detecting NO and NO2 concentrations as NOX components of an object gas. An NO concentration corresponding value is obtained from a first detection element not having a reduction section. An NO concentration corresponding value is obtained from a second detection element having a reduction section, and having an NO2/NO sensitivity ratio greater than that of the first detection element. The difference ?C between the NO concentration corresponding values of the two detection elements is obtained, and divided by the difference ?S between the NO2/NO sensitivity ratios of the two detection elements, whereby an NO2 concentration corresponding value is obtained. A value obtained by multiplying the NO2 concentration corresponding value by the NO2/NO sensitivity ratio of the second detection element is subtracted from the NO concentration corresponding value of the second detection element, whereby an NO concentration corresponding value is obtained.Type: ApplicationFiled: February 16, 2012Publication date: August 23, 2012Applicant: NGK SPARK PLUG CO., LTD.Inventors: Kenji KATO, Kouji SHIOTANI, Takeshi KAWAI, Satoshi TERAMOTO

Patent number: 8244940Abstract: A peripheral device of the invention is capable of data communication with a host device via one of a first-type interface and a second-type interface having different data communication-related specifications. The peripheral device has a single connector for making electric connection selectively with a first-type connector or a second-type connector. The peripheral device also has a controller for performing an initial connection process that makes a logical connection between the peripheral device and the host device via the first-type interface or the second-type interface. While the physical connection is maintained, the controller breaks the logical connection established by the initial connection process and subsequently makes another logical connection between the peripheral device and the host device.Type: GrantFiled: April 27, 2011Date of Patent: August 14, 2012Assignee: Buffalo Inc.Inventors: Suguru Ishii, Tsukasa Ito, Kenji Kato

Publication number: 20120160012Abstract: [Objective] To provide a gas sensor which can improve the sensitivity to NOX. [Means for Solution] A reduction section 18 for reducing NO2 contained in exhaust gas to NO is provided on the upstream side of a first diffusion resistor section 103 provided to limit the flow of the exhaust gas into a first measurement chamber 101. When NOX passes through the first diffusion resistor section 103, NO2 which is greater in molecular weight than NO is lower in the degree of diffusion than NO. Since NO2 is reduced to NO at the reduction section 18, the exhaust gas passing through the first diffusion resistor section 103 hardly contains NO2. Therefore, the speed of flow of NOX through the first diffusion resistor section 103 is not limited by NO2, whereby sensitivity for detection of NOX can be improved.Type: ApplicationFiled: December 23, 2011Publication date: June 28, 2012Applicant: NGK SPARK PLUG CO., LTDInventors: Kenji KATO, Kohei ITO
