  • Patent number: 9665018
    Abstract: A measuring apparatus measures a position of each of shot regions formed on a substrate. The apparatus includes a detector configured to detect a mark formed with respect to a shot region on the substrate, and a processor configured to obtain a position of each of the shot regions based on an output of the detector. The processor is configured to obtain a coefficient of a regression equation for obtaining a position of each of the shot regions, based on an output of the detector with respect to each of a plurality of sample shot regions on the substrate, and obtain, if the coefficient satisfies a tolerable condition for a discrepancy between the coefficient and a reference value thereof, the position of each of the shot regions using each offset amount that is obtained beforehand to correct the position of each of the shot regions obtained based on the regression equation.

  • Patent number: 8903599
    Abstract: A failure determination device capable of performing failure determination for a shutter device of a vehicle with accuracy in a short time period. In an engine room of a vehicle, a condenser for a refrigeration cycle for an aircon is provided and at a front grille of the vehicle, a grille shutter device is provided for introducing ambient air for cooling the condenser into the engine room by opening a grille shutter. According to the failure determination device of the shutter device, a pressure of the refrigerant discharged from the condenser is detected as a refrigerant pressure. A failure of the grille shutter device is determined based on the refrigerant pressure, which changes at a large rate according to the opening/closing of the grille shutter, enabling failure determination with accuracy in a short time period.

  • Patent number: 7404291
    Abstract: An exhaust gas purifying apparatus for an internal combustion engine, including a filter provided in an exhaust system of the engine for trapping particulates in exhaust gases, and a pressure difference sensor for detecting a pressure difference between an upstream side pressure of the filter and a downstream side pressure of the filter. A non-frozen state of the pressure difference sensor is determined based on at least one of a first parameter relevant to an exhaust gas temperature of the engine and a second parameter relevant to an atmospheric temperature.

  • Patent number: 6715738
    Abstract: A fuel-air mixture control apparatus for adjusting the mixture of fuel and air that a carburetor provides to an internal combustion engine. A mixing passage provides a fuel-air mixture to one or more combustion chambers of an internal combustion engine. A main fuel supply passage provides fluid communication between a fuel source and the mixing passage through a main fuel nozzle. An idle fuel supply passage provides fluid communication between a fuel source and the mixing passage through an idle fuel nozzle. An idle fuel ratio control valve adjusts the proportion of fuel drawn into the mixing passage through the idle fuel supply passage to the flow rate of air drawn into the mixing passage. The idle fuel supply passage is in fluid communication with the main fuel nozzle. Vacuum pressure induced by flow rates across the main fuel nozzle, which exceed a predetermined flow rate, precludes idle fuel flow into the mixing passage.

  • Patent number: 6688585
    Abstract: A carburetor for a scavenged two-stroke internal combustion engine has an enriched fuel-and-air mixing passage extending through a housing of the carburetor. Engaged to the housing is a body of an air flow modular assembly which carries a primary air flow passage which houses a butterfly-type control valve therein. The throttle valve of the fuel-and-air mixing passage is mechanically linked or cammed to the control valve of the air flow passage so that opening of the throttle valve soon after opens the control valve allowing additional air to enter and provide a leaner fuel-and-air ratio in the combustion chamber of the engine when running under load. The air flow modular assembly has a sealing-and-bearing assembly which eliminates air leakage from the surrounding environment along the shaft of the control valve and into the primary air flow passage. The sealing-and-bearing assembly has a bushing which inserts into a counter bore of a cylindrical bore which receives the rotating shaft of the control valve.
