When coming into contact with a detection target gas, the catalytic electrode generates heat, and the resistance of a thermistor layer of a sensing portion is decreased. Since the heat generated by the catalytic electrode is directly transferred to the thermistor layer without passing through an insulating layer or the like, high detection sensitivity is obtained.

  • Patent number: 8542955
    Abstract: A gas detection system is provided for identifying a gas. The gas detection system includes a sensing module with a hollow chamber enclosed by a chamber housing. Additionally, the sensing module includes an optical sensing fiber positioned within the hollow chamber. The optical sensing fiber includes a gas sensor including a fiber Bragg grating positioned at a grating location along the optical sensing fiber, and a sensing layer affixed to an exterior surface of the optical sensing fiber at the grating location. After the gas is directed into the hollow chamber, the sensing layer and the gas exchange heat energy, based in part on a heat transfer coefficient of the gas. The exchange of the heat energy induces a shift in a Bragg resonant wavelength of the fiber Bragg grating which exceeds a threshold shift required for detection, where the shift is used to identify the gas.

  • Publication number: 20130091925
    Abstract: Black shales differ from conventional gas plays in that in most cases there exists minimal geological scale gas migration. Thus, it is difficult to perform accurate reservoir characterization using classic geophysical and geological techniques (i.e. seismic analysis, gravity anomalies, structural geology, etc.). The principal technique that has traditionally been applied to determine the genetic history of gases or other fluids in the Earth's crust is the analysis of carbon isotopic composition of hydrocarbon gases and carbon dioxide, which has significant gaps in differentiating thermal and migrational histories. The present invention describes a method to determine the genetic fingerprint (i.e. identify the source formation and migration histories) of hydrocarbon gases or other crustal fluids of a geological system at lower cost and greater accuracy than existing methods (carbon and hydrogen isotopes) by analyzing the intrinsic, atmospheric and radiogenic (i.e.

  • Publication number: 20130081445
    Abstract: The described sensor allows determination of the concentration of a gas in a two-component mixture at variable pressure by measuring the diffusivity and the thermal conductivity. The sensor is provided to alternately heat the membrane (12) of a thermally conductive cell (1) and allow it to cool such that the temperature TM of the membrane passes from a first stable value to a second stable value and vice versa via a transient mode. The cell produces a signal representative of the temperature TM of the membrane and the sensor extracts from the signal a first and a second parameter that respectively relate to said first stable value and said transient mode of the signal. A value of the concentration of said gas and of the pressure of said two-mixture is calculated from these two parameters.

  • Publication number: 20130000384
    Abstract: Gas pressure in a cavity is detected with a rod-shaped casing that attaches to an hole that opens into the cavity. A porous filter whose top end face matches with a mold cavity face at a top end of the rod-shaped casing separates gas from melt. Cavity gas from an introduction chamber introduces gas through the porous filter, and a gas pressure sensor detects pressure in the chamber. Melt pressure in the cavity is detected with a pressure transmission rod inserted into the rod-shaped casing whose top end face matches with the mold cavity face, and a pressure sensor fixed and held facing a rear end of the pressure transmission rod detects the cavity melt pressure. Cavity melt temperature is detected with a temperature sensor attached to a thin hole formed at the pressure transmission rod's center and includes a thermocouple at a top end part side of the hole.

  • Patent number: 8340468
    Abstract: Feature points (41, 42, 43) in the heat image (10) of a casting die (1) are extracted and a predetermined geometrical conversion processing is performed on the heat image (10) such that the feature points are superimposed on the reference feature points (61, 62, 63) set in a reference heat image (30) picked up previously to generate a corrected heat image (20). A difference image (40) is generated by superimposing the corrected heat image (20) and the reference heat image (30) such that the corrected feature points (51, 52, 53) in the corrected heat image (20) is superimposed on the corresponding reference feature points (61, 62, 63). With such an arrangement, a highly reliable difference image can be generated even when the imaging field of vision slips off among a plurality of heat images.

  • Publication number: 20120309100
    Abstract: A sample preparation chamber for gas analysis that includes a heating element within is provided. The heating element is maintained at an elevated temperature, such that organic compounds that may be present in an input gas sample are removed via oxidation and/or thermal decomposition to provide a treated gas sample that is substantially free of organic contaminants. The treated gas sample may then be analyzed in a gas analysis instrument (e.g., an optical spectroscopic instrument, a mass spectrometer, etc.) to provide results that are free from interference due to organic contaminants. Preferably, the heating element is configured as a Ni—Cr wire. An important feature of this approach is that the heating element (and the rest of the sample preparation chamber) are not altered in operation to remove the organic compounds.
