Abstract

PURPOSE:To secure the recording onto one sheet of the recording paper about the sea bottom, the mid-sea and the surface of sea respectively in order to obtain an easy-to-see by installing the 1st and 2nd transmitters plus the transmitter/receiver, the receiver, the memory, the recorder and others which are connected to the 1st and 2nd transmitters. CONSTITUTION:The plotting state onto recording paper 8 is shown in the diagram along with installation of the following units: 1st and 2nd transmitters/receivers 1 and 2; 1st and 2nd transmitters 2 and 2'; 1st and 2nd receivers 3 and 3'; 1st and 2nd memories 4 and 4'; reading timing signal generator 5; recording head 6; and recorder 7 respectively. With transmission of the pulse signals from transmitters 2 and 2', the ultrasonic pulses are transmitted into the sea from transmitters/receivers 1 and 1' and then returned to 1 and 1' to be memorized in memories 4 and 4' and then read out from generator 5. Thus the recording is carried out on a sheet of paper 8 for the sea bottom, the mid-sea and the sea surface in that order. As a result, a very easy-to-see record can be obtained.
