The present invention discloses an over-current protection apparatus, comprising a current-sensitive element, a first electrode and a second electrode. The first unit operatively communicates with a second unit attached to the article to be located. The context can be determined from various sources including the resource in which the word or link appears and the target resource to which the link points. A lifting device elevates the hinged member away from a lower surface to stretchably reveal display. Accordingly, the size of the pore created between the filtering materials can be adjusted, enabling to conduct filtering and washing operations at a proper level. The flame retardant composition comprises a mixture of a resin having an average particle diameter of not more than 1000 \u03bcm selected from wholly aromatic polyamide, polyimide, polyamideimide, a copolymer of the wholly aromatic polyamide, the polyimide or the polyamideimide or a mixture of the above mentioned polymers and a metal hydrate.
