  • Publication number: 20180272712
    Abstract: Channel grooves for a discharge channel and a non-discharge channel are formed in the surface of an actuator plate by cutting. The discharge channel includes an extension portion and a raise-and-cut portion, and the non-discharge channel also includes an extension portion and a raise-and-cut portion. In an embodiment, an electrode clearance groove is formed in advance by cutting with a dicing blade or the like. After the electrode clearance groove is formed, an electrode is formed by plating. Since plating is performed after the electrode clearance groove is formed, a clearance groove electrode is integrally formed with an AP-side common pad in the electrode clearance groove, and thus the clearance groove electrode and the AP-side common pad are short-circuited. Thus, an electrode separation portion is formed by cutting a short-circuited portion of the clearance groove electrode and the AP-side common pad through cutting or irradiation with laser.

  • Publication number: 20180272714
    Abstract: A discharge channel and a non-discharge channel are formed to have a similar shape, that is, to include extension portions and raise-and-cut portions continuing from end portions of both the extension portions, respectively. Then, imparting of a catalyst, washing of an unnecessary catalyst, plating, and the like are performed on a target surface, as a plating step. In an embodiment, an electrode clearance groove is formed after the plating step. Since channel grooves for the discharge channel and the non-discharge channel have a similar shape, it is possible to cause a water flow to uniformly flow in the channels when washing is performed, and thus to avoid an occurrence of a situation in which a lump is formed in the channel groove by plating.

  • Patent number: 9574512
    Abstract: An apparatus for detecting particulate and a correction method of the apparatus for detecting particulate matter that detects particulate matter within a gas to be measured are provided. The correction method corrects the individual differences inevitably occurring during the manufacturing process of particulate matter detection sensors. The apparatus for detecting particulate matter includes an applied voltage correction means. The applied voltage correction means applies correction information acquired by the correction method to detection control.

  • Publication number: 20170045471
    Abstract: A NOx concentration measurement system has a NOx sensor, a detection section, a NH3 concentration estimation section and a calculation section. The NOx sensor measures a sum concentration c4 of a concentration of NOx (a concentration c1 of combustion derived NOx) in exhaust gas g, and a concentration of NO (concentration c3 of derived NO which has been derived from NH3) oxidized from NH3. The calculation section calculates the concentration c3 of derived NO by using a concentration c2 of NH3 contained in outside exhaust gas which is present around the NOx sensor, not inside of the NOx sensor, and at least one of an air fuel ratio A/F, a concentration of O2 and a concentration of H2O. The concentration c1 of the is calculated based on the sum concentration c4 and the concentration c3 of derived NO.

  • Patent number: 8707761
    Abstract: A shielding part is formed on a detection part in a particulate matter detection element. The detection part has a pair of detection electrodes formed in a comb structure. A shielding layer is made of heat insulating material and formed on the detection part in order to shield a predetermined area having non-uniform electric field intensity. An area having uniform electric field intensity on the detection part is exposed only to exhaust gas as target detection gas when a predetermined voltage is supplied between the detection electrodes in order to detect electric characteristics of the detection part. This structure prevents the area other than the area having the uniform electric field intensity on the detection part from being exposed to the exhaust gas.

  • Publication number: 20120151992
    Abstract: In a PM detection sensor S having a PM sensor element 1 installed in an exhaust-gas pipe of an engine E/G, PM detection electrodes are placed in detection spaces in slits, respectively, formed in an insulation substrate. In the insulation substrate, one slit is embedded between an electric field generating electrode and a common electric field generating electrode. The other slit is embedded between an electric field generating electrode and the common electric field generating electrode. The same magnitude of an electric field is generated between the detection spaces when electric power is supplied to the electric field generating electrodes. An average value of sensor outputs transferred from the PM detection electrode is used as a sensor output of the PM sensor element.

  • Publication number: 20110259079
    Abstract: A gas sensor is capable of detecting a concentration of PM contained in an exhaust gas emitted from a diesel engine. The gas sensor is comprised of a ceramic substrate and detection parts which are formed on the ceramic substrate with resistance parts. A resistance value of each of the resistance parts is changed on the basis of the quantity of conductive particulate matter captured by and accumulated on the detection parts. The detection parts have a different detection range. A part of the detection range of each of the detection parts is overlapped together. The concentration of PM contained in the target detection gas is detected on the basis of the change of the resistance value of the resistance parts.
