摘要:
An ultrasonic atomizing apparatus including an ultrasonic vibration generator and an ultrasonic vibrator horn having a cylindrical section connected at one end to the ultrasonic vibration generator and having a flared portion connected to the other end of the cylindrical section. The flared portion is flared and enlarged in diameter towards the tip end of the horn and is adapted to atomize liquid material on the flared portion as the liquid material is supplied from a liquid material supply nozzle to the flared portion. A hollow recess is formed in the flared portion opening toward the tip end of the horn. The geometry of the hollow recess is such that the cross-sectional area of the flared portion of the horn in any plane perpendicular to the longitudinal axis of the horn is the same as the cross-sectional area of the flared portion in all other planes perpendicular to the longitudinal axis of the horn. The horn also has a single nodal point positioned above a boundary between the cylindrical section and the flared portion when the horn is ultrasonically excited.

Provided is an atomizer-equipped combustion apparatus including an atomizing device for atomizing a fuel, a spray chamber for mixing the fuel atomized by the atomizing device with air to form a mixture, and for moving the mixture downwardly toward an opening at a distal end portion of the spray chamber, and a wind box provided so as to surround a lower portion of the spray chamber for forming a combustion space between itself and the spray chamber, the wind box being provided with a plurality of air supply holes facing a lower portion of the spray chamber. A mixture of external air and a fine spray of fuel produced by the atomizer can be ignited instantaneously by means of a comparatively simple structure, odors produced at igition and extinguishment can be greatly suppressed and a high turn-down ratio can be obtained.

An ultrasonic vibrator horn for use with ultrasonic atomizing apparatus for atomizing liquids, such as liquid fuels, employed in gasoline engines, diesel engines, gas turbines and various combustors such as industrial, commercial and domestic boilers. The ultrasonic vibrator horn has a body portion connected at one axial end thereof to an ultrasonic vibration generating means. The other axial end of the body, at which atomization of liquid material fed to the horn takes place when the horn is driven by the vibration generating means, is of conical shape. The body has at least one external groove formed in it. The groove communicates with the conical end of the body for receiving the liquid material and directing it to the conical end.

An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4π radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.

摘要:
A first color conversion unit converts RGB signals from a line input unit to L*a*b* signals. A lightness range compression unit matches the lightness range of the input color signals with that of an output gamut. If the maximum saturation point on an input line is outside the output gamut, an input line correction unit corrects the point in such a manner that it is mapped onto the surface of the output gamut. If a near-surface determination unit determines that the corrected line is not located on the surface of the output gamut, an out-of-gamut mapping unit maps it onto the surface of the output gamut, whereas if it determines that the corrected line is located near the surface of the output gamut, the surface mapping unit maps all points on the surface of the output gamut. A second color conversion unit converts the mapped L*a*b* signals to CMYK signals.
