Abstract: An embedded type motorized blind device. A power supply section has a motor. A power transmitting section has a worm gear coupled to the shaft of the power supply section, a worm wheel positioned on and meshed with the worm gear, a planetary gear formed on a side surface of the worm wheel, and a quadrangular shaft formed integrally with a front end of the worm gear. A control section has an internal sun gear meshed with the planetary gear, a pair of swing arms securely locked to a center shaft fastened to a bottom wall of the internal sun gear, and a pair of limit switches operated by lower ends of the swing arms to control raising and lowering of a blind. An operating section has raising and lowering drums connected one with another, and tilt adjustment parts respectively placed on the raising and lowering drums.

Abstract: The present invention is a compacting apparatus for waste, glass, and plastic. The present invention compresses such objects in order to simplify both the recycling and disposal processes. Objects placed in a box within the apparatus are compressed by a flat surface perpendicularly attached to a vertical shaft. This shaft is pressed downward by a conventional hydraulic system installed in the top of the apparatus. One box is provided with heat-producing coils installed within its walls for softening hard plastic and PVC. Another box without heat-producing coils is provided for crushing glass and waste. A cutting device is provided for cutting objects too large to fit inside the box.
