Abstract: Disclosed is an exhaust reflux type cleaning robot. In the cleaning robot, foreign substances along with air are sucked into a suction unit by a suction motor, and the foreign substances are collected in a dust collecting unit while the air from which the foreign substances have been removed is discharged to the outside via the suction motor. The cleaning robot includes an exhaust reflux unit which has the suction motor and is provided with left and right air passages disposed on opposite sides of the suction motor, a discharge nozzle unit which is connected to the left and right air passages, a suction unit which is configured such that the discharge nozzle unit is disposed in front of the suction unit, and a sterilization anion generating unit which generates sterilization anions to sterilize air discharged via the suction motor.

Abstract: Disclosed is an exhaust air feedback robot cleaner equipped with a disinfectant anion generator, including a suction motor to intake not only air but also dust from a to-be-cleaned surface through a suction unit installed at the bottom surface and a dust collector to trap dust so as to allow dust-free air to be discharged via the suction motor. In the robot cleaner, the disinfectant anion generator emits disinfectant anions to disinfect the air having been discharged via the suction motor, a spray nozzle installed at the front end of an intake port of the robot cleaner sprays the disinfected air toward the cleaning surface through an exhaust air feedback unit so that the dust on the to-be-cleaned surface may be scattered and disinfected, and finally the air, together with the dust, is sucked in by the suction motor and circulated again to the exhaust air feedback unit.

Abstract: A VCR-projector assembly that permits projection of a video signals of a TV or video tape in a desired direction. The VCR-projector assembly includes a key application part including various keys, a tuner for tuning broadcasting signals received through an antenna, a VCR for recording the broadcast signals from the tuner and reproducing the recorded broadcast signals or other recorded signals, e.g.

Abstract: A movie camera system having a function for projecting an image of an object being presently or previously imaged on an external screen, as well as a function for monitoring the image and a method of displaying a video signal therein. A composite video signal from a camera section or a VCR section is processed by a video signal processor in a display section so that it can be displayed on a display device including a matrix of pixels. The processed video signal from the video signal processor includes red, green and blue color signals. Arrangement of the proposed video signal is changed according to whether the projecting function or the view finding function is selected. According to the selected function, an optical image resulting from the video signal displayed on the display device is lighted by a large or small amount or light from a light source at the rear. The user can view or monitor the image on the display device through a focus lens unit at a front portion thereof.

Abstract: A light amount controlling apparatus includes a light source for producing light and a light source driver for driving the light source. A zoom lens unit includes a zoom lens for varying an angle of projection of the light, and a zoom lens position detector detects a position of the zoom lens. A memory stores control data corresponding to the position of the zoom lens and a memory controller reads the control data from the memory according to a detected value of the zoom lens position of the zoom lens position detector. A controller controls the light source driver to vary an amount of light projected from the light source in accordance with the control data output from the memory controller.
