Amendment March 7, 1986 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] Periodically arriving ultrasonic detection information is written in the main memory as digital information, and the stored information in the main memory is periodically read out and the read stored information is used as the original detection information. In order to display the color according to the level,
Ultrasonic detection in which the signal is converted into a color signal and supplied to a color cathode ray tube display device, and one piece of detection information is displayed as a single display line on the display screen of the cathode ray tube display device, and the display lines are arranged sequentially in chronological order. In the display device, in addition to directly displaying the information stored in the main memory , averaging means for adding and averaging adjacent information of storage elements in the main memory corresponding to the scanning direction of the display device of the cathode ray tube; means for inserting and displaying the output of the averaging means between directly displayed information ; zero level detection means for detecting that at least one of the two pieces of information to be added in the averaging means is at zero level; and means for supplying one of the two pieces of information to be averaged to the cathode ray tube display device as a display signal based on the level detection output .

Claims (1)

[Scope of utility model registration request] Ultrasonic detection information that arrives periodically is written into the main memory as digital information, and the stored information in the main memory is periodically read out and supplied to the cathode ray tube display device, and the detection information is displayed on the display surface of the cathode ray tube display device. In an ultrasonic detection display device in which the display line is displayed as a single display line and the display lines are arranged sequentially in chronological order, in addition to directly displaying the information stored in the main memory, it also corresponds to the scanning direction of the cathode ray tube display device. An ultrasonic detection and display device which adds and averages adjacent information in storage elements in a main memory and displays the resultant information by inserting it between directly displayed information in the scanning direction.
