Abstract: A desk of the present invention has a plank member with a slot and a retractable board. Two parallel rails are provided in the slot and engaged with the retractable board. The retractable board is moved between a retracted condition and an extended condition. When the retractable board is moved to the retracted condition, the retractable board is located in the slot of the desk, and when the retractable board is moved to the extended condition, the retractable board is moved out of the slot and substantially perpendicular to the plank member.

Abstract: A high heat-dissipating lubricant aluminum-based cover plate and production process thereof comprises a composite material, an aluminum foil layer and a lubricant layer, wherein said composite material is composed of a core material associated at its rear side with a cast film, said aluminum foil layer is associated by pressing under heat with said cast film of said composite material, and said lubricant layer is applied over the surface of said core material of said composite material and is one selected from nonyl phenol polyethylene glycol ether, polyethylene glycol (PEG), polyvinyl alcohol (PVA) and water soluble epoxy resin, or mixtures of equal ratio thereof; thereby, during drilling, a drilling point can be lubricated by said lubricant layer first and hence its piercing force can be buffered.

Abstract: A resin matrix composite with aluminum for lubrication in drilling comprises a resin matrix composite and an aluminum foil. The resin matrix composite is consisting of at least three of the following materials: PEG (polyethylene glycol), polyvinyl alcohol (PVA), polyoxyethylene sorbitan laurate, coconut alcohol polyethylene glycol ether, polyethylene glycol nonyl ether, castor oil polyethylene glycol ether, polyoxypropylene polyoxyethylene ether, amylum, glycerol, inorganic filler, and solvents. By one of roller coating, spin coating, film coating, static spray coating, or halftone printing, the resin matrix composite can bind the aluminum foil to form a resin matrix composite with aluminum foil for applying on PCB (printed circuit board) to function as lubricating in drilling.

Abstract: An improved structure of a combination file folder includes a pair of clip boards and a connection board which mounted together to form a file folder. The file folder is made from plastic materials and can be detached from one another. Thus, the packaging and transportation costs are greatly reduced, as the file folder does not occupy a large space. Based on the need of the size of the file folder, the change of the connection board can satisfy the needs of the consumers.
