    • The present invention concerns a method for producing a foamed product based on aromatic polyester resin, wherein at least one of IPA, DEG, TEG and PEG is selected and copolymerized at the step of aromatic polyester polymerization to produce aromatic polyester resin with a low melting point whose melting point ranges 80 to 180□. The resin is then cross-linked by means of an organic peroxide cross-link agent, subject to melt mixing at a temperature ranging 80 to 180□ and then foamed in order to produce a foamed product based on aromatic polyester resin of a low melting point, excellent in thermal resistance, foaming magnification, strength, etc. The aromatic polyester resin represented by polyethyleneterephthalate is known excellent in chemical properties such as chemical resistance, solvent resistance, weather resistance, etc., and physical properties such as thermal resistance, dimension stability, rigidity, gas barrier capability, etc., and thus widely used for packaging electric/electronic parts, films, bottle containers and the like.

    • An anti-loosening device of parking brake has developed for providing a secure parking brake mode with the simplest structure comprising: a ratchet wheel having multiple teeth formed on an arc-shaped edge, an operating lever having an upper portion forming a tube-shaped handle, a lower portion forming a flat and narrow cavity, a latching mechanism consisting of a pawl, a slot formed sliding length Ls, which is same as sliding distance Lp of a rim cap, a rotating shaft, and an elastic spring, a lever operating mechanism consisting of an operating rod, coil spring, and push button. When the push button is depressed, the operating rod slides along the slot to push the elastic spring. Simultaneously, the elastic spring will develop a resilient force for exerting on the pawl, when the operating rod reaches the end of the slot. Then, the pawl rotates to disengage the arc-shaped teeth, when the operating lever slightly lifts-up.

    • The present invention relates to an RFID reader and a method thereof, and an RFID data processing method. The RFID reader generates a specific query message to a plurality of RFIDs, receives a first response message corresponding to the query message from at least one RFID among the RFIDs, and sequentially identifies a tag ID of a collided RFID by using a collision solving message when a collision occurs according to the result of receiving a first response message. The RFID reader can quickly and accurately identify a plurality of RFIDs since it can eliminate an unnecessary time such as excessive no response slot generation or repeated rounds through a sequential identification process for the collided RFIDs.
