Abstract: A high power LED color bulb with infrared remote function has a reflector having front and rear openings and a light guide hole, a light guide bar received inside light guide hole, an LED module with LED chips and a bulb cover with a controlling circuit board. The LED module is mounted on a rear end of the reflector with the LED chips inside the reflector. The controlling circuit board is inside the bulb cover, is connected electronically to the LED module and has an infrared sensor aligned with the light guide bar of the reflector.

Abstract: A method of densifying a surface of a powder metallurgy article and an apparatus for the same are provided. A powder metallurgy blank is fixed in position in a fixture for being subjected to a surface treatment that employs an actuating member to exert to a pre-selected surface of the powder metallurgy blank simultaneously a spinning force and a vertically pressing force. The pre-selected surface can thus be densified to have sufficient wear resistance due to the application of the bi-directional forces.

Abstract: A cleaning device that may have a body forming a multifunctional plastic receptacle and that may incorporate features providing easy peel back of one turn of depleted adhesive coated sheet material in the cleaning device and facilitating a neat tearing away of the depleted material. In a preferred embodiment, the body is formed of two body members hinged together to substantially fully enclose a roll of adhesive coated sheet material when snapped closed, and when snapped open, to form a continuous handle-like portion. The roll is slit at one end, which when a full turn of depleted material is peeled back, will allow the slit to align with a sharp, molded-in edge of one of the body members to facilitate tearing off the depleted material, starting at the slit. This also facilitates folding the free end to a double thickness for later easy peel back of the next turn.
