摘要： PURPOSE:To simplify an external coupling structure by forming an electrode in a concentric circle shape on the edge surface of one side of resonators and connecting an antenna conductor for external coupling at an electrode at an inside. CONSTITUTION:On the upper surface of 4 and 7 out of resonators 4-7, electrodes 8 and 9 are formed in a concentric circle shape. The electrode 8 at an outside is connected with a metallic film 2 of the inner surface of an enclosure 1 and the electrode 9 at the inside is connected to antenna conductors 12 and 13 inserted through holes 10 and 11 for an external coupling of an upper surface. Thus, the resonators 4 and 7 and an external circuit are electric-field- coupled. The extent of the coupling can be adjusted by changing the size of areas S1 and S2 of the electrodes 8 and 9.

摘要： PURPOSE:To prevent the reproducibility of a resonance frequency from being deteriorated by forming a silver electrode with a prescribed width from the end face of an inner dielectric case brought into contact with an inner wall face to the side face, uniformizing the shape of the electrode formed to the side face of the inner dielectric when bonding the inner dielectric onto the inner wall face of the case. CONSTITUTION:The dielectric resonator consists of an inner dielectric 1, silver electrodes 2, 3, a case 4 and silver pastes 9, 10. Through the constitution above, the inner dielectric 1 is made of a dielectric material having a high dielectric constant such as titanium oxide group ceramic and the silver electrodes 2, 3 with a prescribed width are formed to both end faces. The silver electrodes 2, 3 are formed by coating and baking the silver paste. Moreover, the side plate 4a of the case 4, the bottom plate 4b and the ceiling plate 4c are formed on the surface of the ceramics plate whose linear expansion coefficient is matched with that of the inner dielectric 1 by baking the silver conductor film.

摘要： PURPOSE:To facilitate an adjustment work by constituting the titled adjuster so that a tuning unit is locked with an adjusting spindle to move at the time of putting in/out of said unit, and releasing the lock at the time of not adjusting. CONSTITUTION:A connecting member 4 is inserted between the upper unit 21 and the lower unit 22 of a displacement member 2, and after thus integrating the two units, the member 4 is lowered until it covers the foremost end of the adjusting spindle 5. Then a hexagonal wrench is inserted in the hole 44 of the connecting member 4 and turned clockwise to let a vertical groove 41 provided in the member 4 and a protrusion 51 formed on the spindle 5 engage with each other, and at this time, the protrusion 43 of the connecting member 4 engages in the vertical groove 26 provided in the displacement member 2, thereafter, the member 4 is further turned clockwise so that the protrusion 51 of the spindle 5 engages in the lateral groove 42 of the connecting member, while the protrusion 43 of the connecting member engages in the lateral groove 27 of the displacement member. Being in this state, the adjusting spindle 5 is coupled with the member 2 by the connecting member 4. In such a way, the adjustment work is facilitated.

摘要： PROBLEM TO BE SOLVED: To reduce the area occupied by insulating parts watched from the side of a mounting surface and to attain miniaturization in the width of the same terminal conductor by forming a first insulating part on the mounting surface and forming a second insulating part from the mounting surface to both end faces which is adjacent to it. SOLUTION: On a mounting surface 16 of a dielectric resonator 10 on which a terminal conductor 22 is formed, a first insulating part 23 is formed for insulating the terminal conductor 22 and an outer conductor 14. From the mounting surface 16 of the resonator 10 to both side faces adjacent to it, namely on the two side faces of the resonator 10, a tapered second insulating part 24 is respectively formed so as to link an opening end face 15 and the first insulating part 23. As a result, on the side of the opening end face 15 of the resonator 10, a connecting conductor 21 and the terminal conductor 22 communicated to it are insulated from the outer conductor 14. Thus, the area occupied by the second insulating part 24 as viewed from the mounting surface 16 is reduced, the width of the terminal conductor 22 can be widened, and the resonator 10 can be miniaturized for the width of the same terminal conductor 22.

摘要： PURPOSE: To provide a method which produces a dielectric resonance parts and can reduce the deviation between a dielectric resonator and the center axis of a support base. CONSTITUTION: A columnar dielectric resonator 1 is adhered in a body to a support base 2 having an outer diameter almost equal to the resonator 1 with an adhesive 3. Then the outer circumference surfaces of both resonator 1 and base 2 are ground up to the positions shown by the broken lines respectively. Thus the deviation is eliminated between the resonator 1 and the center axis of the stage 2 for production of a dielectric resonance parts.
