の実用性は大なるものである。 According to the comb filter circuit of the present invention, since the connection to the resistor is made using the electrodes provided on the glass delay medium, there is no need to connect a new lead wire. This method is extremely advantageous in terms of mass production compared to methods that connect and add resistors, capacitors, etc., and can provide products with extremely high connection reliability.
In addition, impedance can be adjusted by changing the resistance value by cutting the resistor, etc., so variations in impedance when connected to a circuit can be easily absorbed by adjusting the resistance value, and adjustment is not required during the set assembly process. Moreover, since the resistor is provided at the end of the common electrode that extends to the side adjacent to the side where the transducer is attached, the resistor can be used even when the glass delay medium is miniaturized. It has the advantage that it is relatively easy to adjust the resistance value by cutting, etc., and it is very easy to mass produce and can provide products with uniform performance, and its practicality is great. be.
