Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 175 words
A resonator device, comprising; an electrically conductive mounting member; at least one axially extending dielectric coaxial resonator having an electrically open axial end and an opposite end axially opposite said electrically open end, including a dielectric member formed with an axially extending bore, an inner conductor member formed on a radial periphery of said bore, and an outer conductor member formed on a radially outer periphery of said dielectric member; means, including an elastic member located between said dielectric coaxial resonator and said mounting member, for securing said dielectric coaxial resonator to said mounting member only elastically, through said elastic member and electrically pressing said dielectric coaxial resonator into electrical contact with said mounting member; and an elastic piece interposed between said opposite end of said dielectric coaxial resonator and said mounting member; said mounting member being formed with a stopper projection contacting said electrically open end of said dielectric coaxial resonator; said dielectric coaxial resonator being secured between said elastic piece and said stopper projection so as to be prevented from being displaced axially.
Claim 2
Dependent Claim 175 words
A resonator device, comprising; an electrically conductive mounting member; at least one axially extending dielectric coaxial resonator having an electrically open axial end and an opposite end axially opposite said electrically open end, including a dielectric member formed with an axially extending bore, an inner conductor member formed on a radial periphery of said bore, and an outer conductor member formed on a radially outer periphery of said dielectric member; means, including an elastic member located between said dielectric coaxial resonator and said mounting member, for securing said dielectric coaxial resonator to said mounting member only elastically, through said elastic member and electrically pressing said dielectric coaxial resonator into electrical contact with said mounting member; and an elastic piece interposed between said opposite end of said dielectric coaxial resonator and said mounting member; said mounting member being formed with a stopper projection contacting said electrically open end of said dielectric coaxial resonator; said dielectric coaxial resonator being secured between said elastic piece and said stopper projection so as to be prevented from being displaced axially.
Claim 3
Dependent Claim 40 words
A resonator device as claimed in claim 1, wherein said securing means includes a first elastic element disposed on the radial periphery of said dielectric coaxial resonator so as to be brought into pressing contact with said dielectric coaxial resonator.
Claim 4
Dependent Claim 96 words
A resonator device as claimed in claim 1, wherein said securing means includes a first elastic member disposed on the radial periphery of said dielectric coaxial resonator and a second elastic member interposed between said mounting member and said dielectric coaxial resonator and diametrically opposed to said first elastic member with respect to said dielectric coaxial resonator so as to interpose said dielectric coaxial resonator between said first elastic member and said second elastic member such that said first elastic member and said second elastic member are brought into pressing contact with said dielectric coaxial resonator.
Claim 5
Dependent Claim 35 words
