摘要： This element can be miniaturized irrespective of the value of the matched capacitance. A circulator (1) is provided with a multilayered board (3) for forming a central electrode (16a) and matching capacitance. The multilayered board (3) is produced by laminating a plurality of dielectric sheets on which the central electrode or the matching capacitance electrode is formed, and burning them integrally. The matching capacitor is structured by connecting in parallel the capacitors formed by laminating many numbers of dielectric sheet pinched by a pair of capacitor electrodes. On the upper surface of the multilayered board (3), there are formed in positions facing the central electrode (16a) a first recess (26) for receiving ferrite (4), and a second recess (25) for receiving a permanent magnet (5). In these recesses, the ferrite (4) and the permanent magnet (5) are installed, respectively.

摘要： The sensitivity of the sensor is improved by reducing the viscous resistance force of a gas exerted on a vibratory element, and reducing noises. The sensor comprises a first vibratory element (14) which is supported by a first supporting beam (15) vibratably in the direction (X-X) parallel to an upper base (12) and orthogonal to the supporting axis (O-O), and a second vibratory element (16) supported on the supporting axis (O-O) in the first vibratory element (14) by a second supporting beam (17), vibratingly in the direction (X-X) and in the direction (Z-Z) perpendicular to the upper supporting base (12). The vibratory elements (14 and 16) are vibratable in the direction (X-X) by the vibration generating parts (18). In this way, when a force (T) causing the second vibratory element (16) to rotate around the supporting axis (O-O), the second vibratory element (16) is displaced in the vertical direction (Z-Z) by the Corioli's force. The magnitude of this displacement is measured by the displacement detecting part (19) as a signal for measuring the angular velocity.

摘要： A dual TM-mode dielectric resonator apparatus comprises a dual TM-mode dielectric resonator consisting of two columnar TM-mode dielectric resonators (1) crossed inside a cavity (2); and a partition (3) of a window for electromagnetic coupling between an external apparatus and the dielectric resonator. The partition (3) is disposed on the side surface of the cavity (2) opposing the external apparatus and constituted by forming a first shield conductor (30a) on a first main plane (S1) of a dielectric sheet (50) and a second shield conductor (30b) on a second main plane (S2). The first shield conductor (30a) includes parallel slits (32) formed in parallel with the longitudinal direction of one of the TM mode dielectric resonators, while the second shield conductor (30b) includes slits (31) formed in a region substantially opposed to the first slits (32). Further, a plurality of such dual TM-mode dielectric resonator apparatuses described above are combined to form a bandpass filter. Accordingly, the degree of electromagnetic field coupling can be adjusted easily and precisely by adjusting the width of the first slits (31).

摘要： A plurality of TEM mode transmission lines (L2 to L5) are structured, by pairs of thin film conductors (21 and 22, 22 and 23, 23 and 24, and 24 and 25) which sandwich thin film dielectrics (31 to 34) by alternately stacking the thin film conductors (21 to 25) and the thin film dielectrics (31 to 34). The phase velocities of TEM waves which are propagated at least by two of the transmission lines (L2 to L5) are substantially equal. The thickness of each of the thin film conductors (21 to 25) is smaller than the skin depth of the frequency used so that the electromagnetic fields of at least two TEM mode transmission lines among the TEM mode transmission lines (L2 to L5) are coupled to each other. In this way, the skin depth can be increased effectively. The conductor loss and the surface resistance can be reduced significantly as compared to those of the conventional electrode. By use of this electrode, a transmission line, a resonator, a filter, and a high frequency device are structured.
