摘要： A method of manufacturing a particulate matter detection element for detecting particulate matter in a gas to be measured includes manufacturing flat-shaped conductor layers, flat-shaped insulating layers, a laminated structure in which the conductor layers and the insulating layers are alternately laminated, and a detecting unit having the conductor layers of different polarities as a pair of detection electrodes on a cross section of the laminated structure. The conductor layers each have a constant thickness, and include conductor layer planar portions having a stripped-pattern cross section, and tapered conductor layer end edge portions each having a triangular cross section, provided on both sides of the respective conductor layer planar portions.

摘要： A porous micromodel network to simulate formation flows includes a substrate, two or more porous micromodels formed on the substrate and a fluid inlet formed on the substrate. The first porous micromodel defines a first fluidic flow pathway and is representative of a first hydrocarbon-carrying formation. Flow through the first fluidic flow pathway is representative of flow through the first hydrocarbon-carrying formation. The second porous micromodel is fluidically isolated from the first porous micromodel. The second porous micromodel defines a second fluidic flow pathway different from the first fluidic flow pathway. The second porous micromodel is representative of a second hydrocarbon-carrying formation different from the first hydrocarbon-carrying formation. Flow through the second fluidic flow pathway is representative of flow through the second hydrocarbon-carrying formation. The fluid inlet is fluidically configured to simultaneously flow fluid to the first fluidic flow pathway and the second fluidic flow pathway.

摘要： Powder flow conveying from a powder feeder to a process (i.e. thermal spray gun) can have instabilities that can be detected and diagnosed using a hose back pressure. Incorporating a pressure transducer in a powder hose line at a connection of the powder hose line and the feeder allows the back pressure to be measured in real time at a high sample rate to detect instability and aid in diagnosing a cause of the instability. Diagnosis includes identifying periodic oscillations in the powder hose line such as acoustics as well as detecting hose clogging and hose rupture conditions. Once detected, proper corrective actions can be recommended to correct the cause of the instability.

摘要： A testing apparatus for onsite creation of cured sample liners necessary for confirming proper rehabilitation of pipelines includes a testing box having a base with a plurality of upstanding side walls defining an open upper end of the testing box. The testing box also includes an electrical power control assembly and an ultraviolet light assembly. A liner support manifold is shaped and dimensioned for supporting a sample liner and for attachment to the open upper end of the testing box for exposing the sample liner to pressure and ultraviolet light. In practice, and with the sample liner secured to the liner support manifold and the liner support manifold secured to the testing box, the sample liner is exposed to pressure and UV light in a highly controlled manner allowing for replication of actual in-line curing processing.

摘要： A system for determining angular position includes a dipole magnet having an axis of rotation, wherein the dipole magnet produces a magnetic field. A first magnetic field sensor produces a first output signal and a second magnetic field sensor produces a second output signal in response to the magnetic field. The magnetic field sensors are operated in a saturation mode in which the magnetic field sensors are largely insensitive to the field strength of the magnetic field. Thus, the first output signal is indicative of a first direction of the magnetic field and the second output signal is indicative of a second direction of the magnetic field. Methodology performed by a processing circuit entails combining the first and second output signals to obtain a rotation angle value of the magnet in which angular error from a stray magnetic field is substantially cancelled.

摘要： Apparatuses for controlling gas flow are important components for delivering process gases for semiconductor fabrication. In one embodiment, a method of calibrating an apparatus for controlling gas flow is disclosed. Specifically, the apparatus may be calibrated on installation using a two-step process of measuring the volume of gas box downstream from the apparatus by flowing nitrogen gas into the gas box and measuring the resulting temperature and rate of pressure rise. Using the computed volume of the gas box, a sweep of several mass flow rates may be performed using the process gas and the gas map for the process gas. The apparatus is calibrated based on the measured temperature and pressure values, which allow calculation of the actual mass flow rate for the process gas as compared with the commanded mass flow rates.

摘要： An air sampling system configured to detect an air quality metric for a plurality of volumetric regions is disclosed. The system comprises an air sample return unit, an air flow controller, and at least one sensor. The air sample return unit is configured to independently transfer air from the plurality of regions as a plurality of air samples. The air flow controller is configured to receive each of the plurality of air samples and selectively direct a selected sample to a sensor supply line and the remainder of the samples to a sample purge line. The at least one sensor is configured to measure an air quality metric of the selected sample and communicate the air quality metric to a controller. The remainder of the air samples are directed to the air sample return unit throughout operation.

摘要： A method and a measuring apparatus for determining specific quantities for the gas quality in which the gas or gas mixture flows through an ultrasonic flow sensor as well as through a microthermal sensor, and the former is used for determining the sound and flow velocity and the latter for determining the thermal conductivity and the thermal capacity of the gas or gas mixture. The sound velocity, the thermal conductivity and the thermal capacity are subsequently used for the correlation of the specific quantities for the gas quality.
