摘要： A small in-band-flat-group-delay type dielectric filter having low-loss characteristics with a small amplitude deviation and uniform-group-delay frequency characteristics is obtained, which enables broad-band characteristics to be obtained easily. The in-band-flat-group-delay type dielectric filter includes a plurality of dielectric coaxial resonators, a coupling circuit comprising a combination of reactive elements, with which the dielectric coaxial resonators are coupled to one another, and input/output terminals connected to ends of the coupling circuit. The dielectric coaxial resonators coupled to the input/output terminals are allowed to have a different characteristic impedance from that of the inter-stage dielectric coaxial resonators.

摘要： A piezoelectric device includes a piezoelectric plate provided with at least one electrode at almost a central portion of each face; a first plate made of an ionic material having a recessed portion to cover the at least one electrode at one face to face the piezoelectric plate; and a second plate made of an ionic material having a recessed portion to cover the at least one electrode at one face to face the piezoelectric plate. Each of the at least one electrode is packaged by direct bonding the piezoelectric plate with the first plate and the second plate so as to be sandwiched therebetween. A package includes a body member made of an ionic material provided with a recessed portion or an opening, having a flat face around the recessed portion or the opening; and a covering member made of an ionic material having a flat face to cover the body member. The flat face of the body member and the flat face of the covering member are cleaned and attached to each other so as to be direct bonded with each other using hydrogen bonds generated between the ionic materials, thereby packaging the recessed portion or the opening.

摘要： In a laminated dielectric resonator, two-fold strip line is formed and resonant frequency is lowered. Accordingly, the length of the resonator is reduced, and the length of the strip line becomes shorter than one fourth of the wavelength with the lowered resonant frequency, which leads to further reduction of the length of the resonator. By lowering the resonant frequency, dielectric material with less relative permittivity can be used, with a result of resonator with high unloaded Q and excellent temperature characteristic. Further, at least one coupling electrode is formed as external or internal electrode to compose a capacitor together with a second strip line, and a laminated dielectric resonator is connected to an external circuit via the coupling electrode. A dielectric filter such as band pass filter, band elimination filter is so composed that the dielectric resonators are cascade-connected to one another. In the thus constructed dielectric filter, external coupling capacitors are unnecessary, reducing the number of parts and facilitating the manufacturing process. Thus, a small-sized, low-cost dielectric filter is attained.

摘要： A radio-frequency heating apparatus includes a heating chamber, first and second radio-frequency wave generation devices from which radio-frequency waves are radiated, and a control unit that controls the first and second radio-frequency wave generation devices. Each of the first and second radio-frequency wave generation devices includes: a radiation unit that radiates radio-frequency waves into the heating chamber; and a backward wave demodulation unit that demodulates backward waves entering from the heating chamber. The backward wave demodulation unit of the first radio-frequency wave generation device detects reflected waves that are radio-frequency waves radiated from the radiation unit and reflected back into the radiation unit, and through waves that are radio-frequency waves radiated from another radiation unit and enter the radiation unit. The control unit controls the first and second radio-frequency wave generation devices based on the detected reflected waves and through waves.
