摘要： In a dielectric resonator device, the outer shape of a support base is larger than the bottom surface of a dielectric core which is in contact with the support base, and the support base is fixed on the inner bottom surface of the cavity with support columns at the periphery of the support base. With this configuration, an air space can be provided between the inner bottom surface of the cavity and the support base. Accordingly, the resonant frequency of the TMz mode in which the electric field vector directs perpendicularly to the surface of the support base is increased so that it is considerably away from the resonant frequency of the TE01δ multiple mode.

摘要： A dielectric filter, a composite dielectric filter, a dielectric duplexer, a dielectric diplexer, and a communication apparatus, in which isolation between adjacent dielectric filters can be obtained, and deterioration of filter characteristics can thereby be prevented. A plurality of dielectric resonators formed by disposing dielectric cores in cavities, and coupling loops for coupling to predetermined resonance modes of the dielectric resonators, are combined to form a dielectric filter. The dielectric resonators and the coupling loops are arranged in such a manner that when the dielectric resonators of the dielectric filters are close to each other, the directions of the coupling portions of the adjacent coupling loops are substantially vertical to each other.

摘要： A dielectric filter exhibiting excellent filter characteristics in which the manufacturing cost is reduced by forming coupling loops for dielectric resonators generally in the same shape. First through fourth TM double-mode dielectric resonators are aligned in a row with their openings facing in the same direction. First and second metallic panels are screwed to the resonators to cover their openings. An input loop and an output loop are mounted on the first panel in such a manner that they obliquely face the intersecting areas of the respective dielectric members of the first and fourth dielectric resonators, respectively. Also attached to the first panel are generally "V"-shaped coupling loops. Also disclosed is a dielectric duplexer constructed of a plurality of such dielectric filters.

摘要： A walking shoe that senses a fall and urges a user of the shoe to perform movement for fall prevention. When the walker stumbles or almost falls, a microprocessor is activated, based on a sensing signal of a pressure-sensitive sensor that senses a pressure applied to a tread to detect a lifting velocity and/or a lifting amount of the foot based on a detection signal of an acceleration sensor, and when the lifting velocity and/or the lifting amount is lower than a reference value, the microprocessor actuates a stimulator that stimulates a bottom of the foot. At this time, since the user reflexively lifts the foot, the user can avoid stumbling.

摘要： A method and an apparatus for exactly and automatically adjusting the characteristics of a dielectric filter in a short time period. The characteristic parameters of a dielectric filter are measured, electric parameters of a designed equivalent circuit of the filter are calculated with the use of characteristic parameters, characteristic adjusting portions of the dielectric filter are adjusted, while at the same time, adjustment functions indicating the variation amounts of electric parameters with respect to adjusting amounts are calculated with the use of the electric parameters and the adjusting amounts which have been changed by the above adjustment. Then, in accordance with simultaneous equations involving adjustment functions, an adjusting amount is calculated with the use of a difference between a present electric parameter and a desired electric parameter, thereby effecting an adjustment which is for example 50%. By repeatedly conducting the above treatments, the characteristic parameters of the filter will be allowed to successively get closer to the desired values.

摘要： In a sheet-type piezoelectric vibrator provided with a piezoelectric sheet made from a transparent organic polymer and electrodes formed on respective main surfaces that are opposite to each other of the piezoelectric sheet, an electrode material that is effectively used for making the vibrator colorless is provided. The first electrodes formed on one of the main surfaces of piezoelectric sheets are made of zinc oxide electrode layers, each mainly containing zinc oxide, and second electrodes formed on the other main surface of the piezoelectric sheets include polythiophene electrode layers made from a conductive polymer containing thiophene in a molecule structure thereof. Although the zinc oxide electrode layer is transparent, it is slightly yellowish, while, on the other hand, although the polythiophene electrode layer is also transparent, it is slightly bluish. Since the spectral characteristic of light transmitted through these two electrode layers is made substantially flat in the visible region, the coloring of the transmitted light is suppressed so that the layers appear colorless and transparent.
