  • Publication number: 20140302341
    Abstract: In a hot press molding method for press-molding a heated material and cooling the material while holding the material in a mold, during press molding of the material, shape changes including a portion that curves with respect to a longitudinal direction of the material are molded at longitudinal opposite end portions of the material and resistance to thermal contraction force of the material in the longitudinal direction during cooling is imparted. In one embodiment of the present invention, the shape changes molded on the material during the press molding are minute protrusions provided on surfaces of the longitudinal opposite end portions of the material. The invention makes it possible to suppress thermal contraction of the material during cooling in hot press molding to thereby prevent defects associated therewith.

  • Patent number: 8826727
    Abstract: A gas sensor including a reduction section (18) for reducing NO2 contained in exhaust gas to NO. The reduction section (18) is provided on the upstream side of a first diffusion resistor section (103) which limits the flow of the exhaust gas into a first measurement chamber (101). When NOX passes through the first diffusion resistor section (103), NO2 which has a greater molecular weight than NO has a lower degree of diffusion. 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.

  • Publication number: 20140136136
    Abstract: An NOx detection apparatus computes a first NOx concentration NOxpo on the basis of a second pumping current Ip2, and sets correction coefficients a, b (concentration variation correction information) on the basis of the first NOx concentration NOxpo. Therefore, the NOx detection apparatus can set the correction coefficients a, b in accordance with the concentration of NOx actually contained in a to-be-measured gas. Since the NOx detection apparatus uses Equation 3, determined by the correction coefficients a, b, for correction of the first NOx concentration NOxpo, the NOx detection apparatus can correct the first NOx concentration NOxpo in accordance with the state of change of the NOx concentration even when the magnitude of an output variation caused by a pressure change changes depending on the NOx concentration.

  • Publication number: 20140029792
    Abstract: A vehicle light source detection device in a light beam control system detects a position of a light source appeared and detected in captured image data The device calculates a gradient of a road on which the own vehicle is running. The vehicle light source detection device estimates a vanishing point in the captured image data on the basis of the detected gradient of the road. The device further increases a reliability value of the detected light source when the point of the detected light source more approaches the vanishing point. When the reliability value of the detected light source is not less than a predetermined reference value, the device determines that the detected light source is a head lamp of an oncoming vehicle, and adjusts an irradiation range of the light beam of the head lamps of the own vehicle to avoid the oncoming vehicle.

  • Publication number: 20140029791
    Abstract: A processing section as a light emitting source detection device in a light beam control system changes irradiation parameters, one of an irradiation range and a luminance of a light beam of head lamps of an own vehicle. The light beam of the head lamps is irradiated toward a light object corresponding to a light source detected in captured image data. The processing section detects whether or not the luminance of the detected light source is changed after the change of the irradiation parameters, and sets a probability value of the detected light source to a value lower than a probability value of a light source when luminance is not changed even if the irradiation parameters are changed. When the probability value of the detected light source is not less than a predetermined threshold value, the processing section determines that the detected light source is a vehicle light source.

  • Patent number: 8512536
    Abstract: A NOx sensor includes a sensor element equipped with first and second pumping cells to define first and second measurement chambers. The first pumping cell exerts an oxygen pumping action against the first measurement chamber to adjust the oxygen concentration in the gas under measurement within the first measurement chamber to a given level. The second pumping cell exerts an oxygen pumping action against the second measurement chamber to produce a pumping cell current according to the NOx concentration in the gas under measurement. When the moisture content of the gas under measurement changes from 2 vol % to 8 vol %, the NOx sensor allows a variation of NOx concentration detection value based on the pumping cell current in such a manner that the NOx concentration detection value reaches a transient peak value of 20 ppm or smaller and converges to ±5 ppm of a reference value within 5 seconds.
