The incident light beam 10 wavelength lambda is deflected by a deflection angle thetabeta with the ultrasonic wave of frequency (f) inputted to the modulator to form an image at a position 10b on an image plane 4 while displaced from an original projection position 10a. Then, thetaS=lambda/2LAMBDA=lambdaf/2V, where LAMBDA is the ultrasonic wavelength and V is the speed.

IPC: B01D53/14
Filed: 1996-02-03
Abstract: PROBLEM TO BE SOLVED: To surely prevent clogging in a waste gas line and to stably process waste plastics into an oil, by introducing the waste gas produced by heating waste plastics into an absorbing tower so that the waste gas is absorbed or brought into contact with an absorbing oil in the tower to remove impurities, and then neutralizing the gas by combustion.

The waste gas is sent through lines 30a, 30b to an absorbing tower 31, while a part of the decomposed and produced oil is discharged through an oil supplying tube 33 and introduced through a bypass pipe 34 into the absorbing tower 31 so that the oil is brought into contact with the waste gas as a counter flow. By the contact of the gas and the oil, the absorbing oil traps dust, crystal component and org. vapors in the waste gas and dissolve these or contain these in a slurry state. Therefore, clogging in the waste gas lines 30a, 30b can be surely prevented.

Abstract: PURPOSE: To realize the wavelength conversion and light amplification with a single means by using a space modulating means in an optical path constituting an image projecting device and providing a wavelength selecting means on the reading-side optical path. CONSTITUTION: The light emitted from the reading side of an SLM(Space light modulating means) 109 is modulated according to the intensity of the light incident on the writing side of the SLM 109, and the emitted light is projected through a three primary color filter 119, a lens 117, and a beam splitter 115 to provide a projected image 121. Since the contrast of the projected image depends on the light intensity of the light source incident on the reading side of the SLM 109, the light intensity of a light source 103 for lighting a document 101 can be set low.  Considering the response speed of the SLM 109, the rotating speeds of the three primary color filters 107, 119 arranged on the writing side and reading side of the SLM 109 are synchronized with each other, and the light passed through the writing-side filter 107 is consequently passed through the reading-side filter 119, thereby, the cross talk of color is avoided.
