    摘要: A micro-Raman spectroscopy system capable of making effective use of the unique analyzing capabilities of Raman spectroscopy and still capable of employing information about foreign materials obtained by a separate foreign material inspection system. The micro-Raman spectroscopy system uses a sample stage having a function of reproducing an image of a foreign material on a wafer under an optical microscope, based on positional information previously obtained from foreign materials by the separate foreign material inspection system. Furthermore, the micro-Raman spectroscopy system has a function of searching a built-in database for the substance of the foreign material on the wafer, using a Raman spectrum presently obtained from the foreign material. The system includes a Raman analysis optical system and a Raman spectrometer that are connected by optical fiber.

    摘要: In an internal combustion engine having a plurality of electromagnetically driven valves for each cylinder, when an required EGR amount Er is relatively small during an exhaust gas recirculation performed independently of the exhaust stroke, a first exhaust gas recirculation mode is entered by driving only a first exhaust valve of each cylinder. An open valve duration Td1 for achieving the required EGR amount Er in a one-valve drive manner is longer than a corresponding open valve duration in a two-valve drive manner. Therefore, even if the required EGR amount Er is small, a “one-valve drive in pattern 1” mode can be achieved provided that Td1>a. That is, the incidence of performing the control in pattern 2, which allows only a narrow range of control, can be reduced. Hence, degradation of controllability can be prevented even if the required EGR amount Er is small.

    摘要: A valve driving apparatus for driving an exhaust valve, using electromagnetic force provided in an internal combustion engine, the exhaust valve being movable between an open position and a closed position. An armature is coupled with the exhaust valve. An em coil generates an em force exerted on the armature. A valve spring generates a force exerted on the exhaust valve. A controller changes a normal state of movement of the exhaust valve to a state of movement that prevents the armature from bouncing off the em coil at the open position when combustion is suspended in the internal combustion engine.

    摘要: An electromagnetic actuating system of an internal combustion engine is provided. The system can hold an armature in a fully closed position or a fully opened position when the engine is started while obviating a necessity of the initial actuation and effectively reducing power consumption of the system. The system includes an engine valve which functions as an intake valve or an exhaust valve of the internal combustion engine, an armature which moves with the engine valve, an electromagnet which attracts the armature in a direction of movement of the engine valve by being supplied with a current and a spring which presses the armature away from the electromagnet. A permanent magnet, which can exert a magnetic attracting force between the armature and the electromagnet, is provided. The system further includes a stop-time current controller which shuts off the current supplied to the electromagnet, after controlling the current supplied to the electromagnet until the armature is attracted to the electromagnet by the magnetic attracting force of the permanent magnet, when a request to stop the internal combustion engine is generated.

    摘要: An emission computed tomograph provided with a collimator ring rotatable about an object being examined and having a plurality of slits for defining the direction of incidence of the radiation emitted from the objection the radiation detectors. The slits are arranged circumferentially of the ring and directed at successively different angles relative to the radial direction of the collimator ring, so that as the ring is rotated, the object is tomographically scanned. The collimator ring may be divided into a plurality of equal arcuate portions, in each of which the slits are directed toward the object in parallel with each other, so that as the collimator ring is rotated to scan the object, only the parallel profile data thereof can be obtained.
