Title: Transmission and reception system of high resolution sonar
Inventor: IRIMOTO YASUNOBU
IPC: G01S15/50
Filed: 1978-01-24
Abstract: PURPOSE:To provide sonar detected images of high resolution free from any time delay without  increasing the size of an electro-acoustic transducer by subjecting the receiving signals of two  systems to specified processing thereby making frequency multiplication. CONSTITUTION:The reflected ultrasonic waves of pulse-modulated linear frequency modulating  ultrasonic waves from the target are received in the two systems R, L of an electro-acoustic transducer 1. The L-system received signal is mixed with the signal of a frequency twice higher than  the central frequency of the transmission waves in a mixer 5 and goes through an LPF 16 to  become the lower side-band which is then multiplied by the R-system receiving signal in a multiplier 11. When the upper side-band being the output signal of the circuit 11 is drawn out with a  BFP 12 is subjected to the mixing similar to that of the mixer 5 with a mixer 13 and is made to a lower side-band with an LPF 14, then it becomes the signal corresponding to the target distance  of a high bearing resolution of the frequency proportional to the delay time of the receiving signals of both systems R, L in correspondence to the target bearing. When this signal is frequency-multiplied with a frequency multiplying circuit 15 which compresses time axis and is then applied to a frequency analysis circuit 16, the signals are processed without time delay.

Abstract: PURPOSE: To avoid the lowering of the output and to increase the reliability by giving etching of several mμ to the fractionated and exposed pn junction to eliminate the damage at the periphery.  
     CONSTITUTION: The GaAs pellet is soaked about 10 seconds into the solution of 25°C temperature obtained by dissolving Br of about 5% into CH 3 OH, and then soaked about two minuted into the solution of H 2 SO 4 :H 2 O:H 2 O 2  = 1:10;1 at 20°C. After this, about 20-second etching is given via the solution of HF:ZHN 3 :H 2 O = 1:3:2 at 30°C. As a result, the exposed surface of the pn junction is etched away about several mμ to eliminate the damaged part caused at the pellet formation time, thus obtaining a highly reliable semiconductor device. With this method, the III-V group compound semiconductor and the mixed crystal compound semiconductor devices can secure the high reliability.
