    摘要: In a case where a succeeding coin has arrived at a coin discriminator (110) before a preceding coin passed through the coin discriminator (110) arrives at a disposition position of a true/false coin distributor (120), the true/false coin distributor (120) is shifted to a false coin side to distribute both of the preceding and succeeding coins to the false coin side. When the preceding coin passed through the coin discriminator (110) is true one and if the succeeding coin has already arrived at the coin discriminator (110) immediately after passage of the preceding coin through the true/false coin distributor (120), the true/false coin distributor (120) is shifted to the false coin side to distribute only the succeeding coin to the false coin side. When the preceding coin passed through the coin discriminator (110) is false one and if the succeeding coin has arrived at the coin discriminator (110) before the preceding coin passes through the true/false coin distributor (120), the true/false coin distributor (120) is shifted to the false coin side to distribute the succeeding coin to the false coin side.

    摘要: A SAW device having a piezoelectric substrate and interleaved metal electrodes formed on the substrate, in which the formation of the electrodes on the substrate is carried out by sputtering. Further, the metal electrodes may contain an additive of Cu, Ti, Zn, Mg, Fe, Ni, Cr, Ga, Ge, Sn, Pd or Ta. The resulting SAW device is capable of dealing with high frequency electric signals of a larger amplitude, or higher power electric signals, as compared with the conventional SAW device.

    摘要: In an apparatus for descrambling a scrambled television signal, an elastic surface wave filter is used. This elastic surface wave filter has an interdigital electrode having an electrode pattern similar to at least portion of the waveforms of a luminance signal section of the scrambled television signal to be input. The elastic surface wave filter generates a response pulse only when the waveforms which are analogous to the electrode pattern of the interdigital electrode of the scrambled television signal were input, thereby descrambling the television signal using this response pulse.

    摘要: A surface acoustic wave filter comprising unidirectional interdigital input and output transducers at least one of which has imperfect unidirectivity and includes two interdigital electrodes arranged to provide a geometrical phase difference .phi..sub.M therebetween and interconnected through a phase shifter which provides an electrical phase difference .phi..sub.E therebetween, the sum of the phase differences .phi..sub.M and .phi..sub.E being unequal to .pi. radians to provide the imperfectness of unidirectivity. The selection range of conductance of an external load or radiation conductance of the unidirectional transducer necessary for suppressing the undesired triple transit echo level can thus be extended while keeping the insertion loss relatively low.
