ABSTRACT:
This invention provides a delay circuit capable of electrically varying the delay amount comprising a first transistor for receiving a signal to be delayed from the base connected to an input terminal and outputting a positive phase signal and a negative phase signal with respect to the signal from the input terminal, respectively from the emitter and the collector thereof; two variable capacity diodes with their terminals of the same polarity connected together and a specified control voltage applied to the point of said connection, one end of the connected diodes being connected to the emitter of said first transistor; a second transistor with the base grounded, the emitter connected to the collector of the above-mentioned first transistor, and the collector connected to one end of a specified resistance; and a delayed signal output terminal having connected thereto the other end of the two variable capacity diodes and the other end of the specified resistance. According to this invention, an ultrasonic diagnosis apparatus using this delay circuit is also provided.
