Abstract: The present invention relates to a cavity filter and a connecting structure included therein. The cavity filter includes: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein the terminal portion includes: a first side terminal contacted with the electrode pad; and a second side terminal having a housing space in which a part of the first side terminal is housed, and connected to the RF signal connecting portion, wherein the first side terminal is provided as an elastic deformable body whose part is radially widened or narrowed against an assembly force provided by an assembler.

Abstract: A secondary battery includes: a can having an accommodation space therein; an electrode assembly accommodated in the accommodation space in the can; and a cap assembly sealed with the can. The can has a beading part recessed into a side wall of the can at a region below where the cap assembly is accommodated, and the beading part has an acute angle with respect to the side wall of the can.

Abstract: Provided are a high-strength medium-low temperature asphalt modifier including: i) a styrenic thermoplastic elastomer powder which is frozen ground to 0.1 to 1 mm at a low temperature, wherein the styrenic thermoplastic elastomer is selected from a polystyrene-polybutadiene-polystyrene block copolymer (SBS), a styrene-butadiene rubber (SBR), a styrene-isoprene-styrene block copolymer (SIS), a styrene-ethylene-butylene-styrene block copolymer (SEBS), and a styrenic thermoplastic elastomer (STE), ii) a high-boiling point process oil, iii) a rosin resin tackifier modified by an aliphatic hydrocarbon, iv) a polymer-silica nanocomposite, and v) an asphalt deodorant, an asphalt mixture prepared using the same, and a construction method thereof.
