A micro coaxial cable includes an inner conductor; an insulation layer having foaming cells and formed to surround the inner conductor; an over-foaming preventing layer formed to surround the insulation layer for the purpose of uniform forming of the foaming cells; a metal shield layer formed to surround the over-foaming preventing layer; and a protective coating layer formed to surround the metal shield layer. The over-foaming preventing layer restrains abnormal growth of foaming cells formed in the insulation layer such that the foaming cells are successively adjacently formed with uniform size. Due to the uniformity of foaming, the dielectric constant of the insulation layer is not locally different but uniform as a whole, thereby capable of improving transmission characteristics. In addition, the micro coaxial cable enables to transmit signals even at a high frequency transmission of GHz range, which was impossible in the prior art.

Disclosed is a polypropylene resin composition with flame retardance and abrasion resistance. The polypropylene resin composition according to the present invention includes 20 to 200 parts by weight of an inorganic flame retardant; and 0.1 to 10 parts by weight of at least one additive, based on 100 parts by weight of a base resin comprising 30 to 90% by weight of polypropylene copolymer resin and 10 to 70% by weight of polyolefin alpha copolymer resin. The polypropylene resin composition according to the present invention can be used for industrial cables with potent endurance since it includes an inorganic flame retardant to show flame retardance and it can remove or reduce a whitening phenomenon and show a significantly improved abrasion resistance without deteriorating moldability or mechanical property even when the contents of the composition are varied to enhance abrasion resistance.

The present invention relates to an ink recharging system in which the ink can be recharged into a used ink cartridge repeatedly, a bulk ink cartridge used in the system, and a method for recharging the ink into the ink cartridge using them. The ink recharging system for the ink cartridge installed in an inkjet printer comprises a compressor and a positive pressure tank for providing the compression force to supply the ink stored in the quantitative ink supply cylinder to the ink cartridge, a charging cylinder for applying the compression force and the suction force to the quantitative ink supply cylinder, automatic quantitative position control means for measuring the movement displacement of the charging cylinder, a vacuum pump and a negative pressure tank for producing a vacuum in the ink cartridge, and a compressed air supply tube diverged and connected to the inlet and outlet of the charging cylinder from the positive pressure tank via the solenoid valve for air pressure. The present invention provides a recharging system for the ink cartridge and a method for recharging the ink cartridge, in which the remaining air or ink in the recycled ink cartridge can be easily discharged and vacuum degree of the ink cartridge can be precisely controlled by the control means for the quantitative position, to thereby charge the quantitative ink into the recycled ink cartridge rapidly and accurately, and relates to a bulk ink cartridge which can prevent wrong installment with simple identifying members.
