    摘要： An interdigital transducer used in an elastic surface wave device and including a pair of electrodes each having a common electrode and a plurality of electrode fingers connected to the common electrode, the overlap lengths of electrode fingers being uniform throughout the transducer. Floating electrodes, each having two parallel conductors connected together at one end, are disposed between the interdigital electrode fingers of the paired electrodes to weight the excitation electric field strength.This invention relates to an elastic surface wave transducer.BACKGROUND OF THE INVENTIONAn elastic surface wave device (also referred to as an acoustic surface wave device) used in the VHF band and UHF band as a filter or delay line already known to those skilled in the art. An elastic surface wave device has transmitting and receiving interdigital transducers disposed on a piezoelectric substrate. These transducers are used to convert electrical signals into elastic surface waves or vice versa.A known transducer used in an elastic surface wave device is of the uniform overlap length interdigital type comprising first and second electrodes disposed on a substrate of piezoelectric material, each of the first and second electrodes having a common electrode connected to an external terminal and a plurality of electrode fingers connected to the common electrode, the overlap lengths of the electrode fingers of the first and second electrodes being uniform throughout the transducer.However, the above-mentioned prior art uniform overlap length interdigital transducer has unsatisfactory frequency characteristics. Further, such transducer has a passband width bearing a substantially inverse proportion to the number of electrode fingers.In Proc. IEEE, Vol. 59, No. 3, p.393, March (1971) is set forth a weighting transducer with a so-called "apodized electrode" arrangement for improving the frequency response of the transducer. With this apodized type weighting transducer, the overlap lengths of the electrode fingers are made to vary in proportion to a weighting function, causing the widths of excited elastic surface wave beams to be weighted in proportion to the weighting function. Though a weighting function with respect to the frequency transmitting property of an ideal filter is sin x/x, a practically used function is, for example ##EQU1## APPROXIMATING THE FUNCTION SIN X /X.When the apodized transducers are used as input and output transducers, it is impossible to obtain the product property of the transfer functions of both transducers. For a prominent guaranteed attenuation in the stop band, however, the product property should be attained. Following is the reason why apodised type weighting transducers used as input and output transducers can not provide a desired product of transfer functions. The electrode fingers of the output transducer overlapping each other over a small length can not fully pick up an elastic surface wave having a larger beam width from the input transducer, failing to produce an output signal proportional to the weight of the beam width.To obtain, therefore, the product of transfer functions, an apodized type weighting transducer is combined with a uniform overlap length type transducer. In this case, the electrodes of the apodized type weighting transducer should be made more precisely than in the case with two weighting transducers in order to attain a prominent guaranteed attenuation in the stop band. However, this is difficult to realize.It is accordingly an object of this invention to provide a weighting transducer, which, combined with any other type of transducer, can easily realize the product property of the transfer functions of both transducers.Another object of the invention is to provide a uniform overlap length interdigital transducer with an improved frequency response.SUMMARY OF THE INVENTIONA uniform overlap length type interdigital weighting transducer of this invention is characterized in that a plurality of floating electrodes each having a pair of parallel conductors connected together at one end are disposed on a piezoelectric substrate between the adjacent interdigital electrode fingers of the first and second electrodes. The parallel conductors preferably extend along the entire overlap length of the interdigital electrode fingers of the first and second electrodes. A plurality of the above-mentioned floating electrodes arranged between pairs of interdigital electrode fingers in numbers progressively increasing from the center of the transducer to both ends thereof along the propagation axis of the elastic surface wave can weight the strength of an excitation electric field in proportion to a weighting function.When combined with any other type of transducer, the weighting transducer of this invention which has the electrode fingers overlapped by each other in the uniform length throughout the transducer, can easily realize the product property of the transfer functions of both transducers.Further, the rejection of the side lobe of the weighting transducer of this invention can be easily improved to a larger extent than 10 dB as compared with the ordinary uniform overlap length type transducer.

    摘要： An electrochromic display device comprises an electrolyte contained between a pair of spaced-apart substrates. A set of electrodes are disposed on at least one of the substrates in contact with the electrolyte and a layer of electrochromic material is disposed on at least one of the electrodes to define a display electrode. The electrochromic material comprises a color-reversible salt of iron(III) hexacyanoferrate(II) which, depending on its oxidation-reduction state, exhibits different colors. A source of electric charge is connected through circuitry to effect reversible electrochemical oxidation and reduction of the salt of iron(III) hexacyanoferrate(II) to effect a corresponding reversible color change exhibited by the display electrode.
