A surface emitting laser device is disclosed that is able to selectively add a sufficiently large loss to a high order transverse mode so as to efficiently suppress a high order transverse mode oscillation and to oscillate at high output in a single fundamental transverse mode. The surface emitting laser device includes a first resonance region that includes an active layer and spacer layers, two distributed Bragg reflectors that sandwich the resonance region, and a current confinement structure that defines a current injection region for the active layer. At least one of the distributed Bragg reflectors includes a second resonance region arranged in the current injection region excluding a predetermined region surrounding a center of the current injection region.

An EGR system includes a high-pressure EGR passage that provides communication between an exhaust pipe, at a portion upstream of a turbine of a turbocharger, and an intake pipe, at a portion downstream of a compressor; a low-pressure EGR passage that provides communication between the exhaust pipe, at a portion downstream of the turbine, and the intake passage, at a portion upstream of the compressor; and an exhaust gas catalyst provided upstream of a position at which the low-pressure EGR passage is connected to the exhaust pipe. When an internal combustion engine is in the transitional state from the low-load operating state to the high-load operating state (S303), if incomplete combustion is detected in the internal combustion engine (S304) and the bed temperature of the exhaust gas catalyst is lower than the reference temperature (S305), the high-pressure EGR gas amount is made larger than the prescribed high-pressure EGR gas amount determined based on the operating state of the internal combustion engine (S306). Thus, an excessive decrease in the intake air temperature is suppressed, and therefore occurrence of incomplete combustion is suppressed.

Approximate position matching processing is firstly performed with respect to entire areas of two images of a single same object. Selection is then made to find local area limited regions, between which a degree of shift is high, in the two images, whose positions have been approximately matched with each other by the approximate position matching processing. Position re-matching processing is then performed with respect to at least the local area limited regions, which have thus been selected. The approximate position matching processing may be global position matching processing, local position matching processing, or a combination of the global position matching processing and the local position matching processing.

A substrate treatment apparatus includes a turntable, a rotative drive unit, a holding pin provided on the turntable, a protection disk for covering a lower surface of a substrate, and a magnetic levitation mechanism that levitates the protection disk from the turntable. The protection disk is vertically movable relative to the turntable between a lower position and an adjacent position above the lower position and close to a lower surface of the substrate. The magnetic levitation mechanism includes a protection disk permanent magnet and an annual guard permanent magnet held by a splash guard. When a guard drive mechanism moves up the splash guard, the protection disk is levitated from the turntable and held at the adjacent position by a magnetic repulsive force generated between the permanent magnets.

Provided is an active vibration noise suppression apparatus having good robustness without determining a secondary transfer function while not performing adaptive control. A first control unit generates a control signal by a first adaptive algorithm as a direct adaptive algorithm. A storing unit stores an equivalent value Gh of a secondary transfer function G which is adaptively updated as an adaptive filter by the first control unit. A second control unit uses a second adaptive algorithm which uses the equivalent value Gh of the secondary transfer function G stored in the storing unit as a feedforward coefficient and updates a filter coefficient C2 of the control signal as an adaptive filter based on the feedforward coefficient. The second control unit generates the control signal by the second adaptive algorithm when the first control unit does not generate the control signal.
