Title: Concentration operation type radiation measurement system
Inventor: GOTO YOSHIMI
IPC: G01T1/17
Filed: 1990-09-17
Abstract: PURPOSE:To prevent drop and overlapping of counted values of a counter with different operation cycles from being generated by transmitting a number indicating order of counter operation along with a measured value of the counter. CONSTITUTION:Output pulse signal of a radiation detector 1 is counted by a counter 3a for each certain cycle through a preamplifier 2 and is input to a central processing device 6 along with counting number (counting number) which is counted up when counting is completed. At this time, a device 6 inspects if the counting number is increased by one as compared with the last time. When a cycle of a transmission device 4a is shorter than operation cycle of the counter 3a, the counting number may agree with that the last counting and counted value is not converted for preventing overlapping. Also, overlapping can be avoided in transmission of counter value for the last n times along with the counter number. Further, when conversion is made so that transmission cycle is longer than a cycle of the counter 3a and if the counting number is larger by 2 or more as compared with the last time, counting value is converted in sequence by that amount as a drop of counting value.

Filed: 1987-09-28
Abstract: PURPOSE:To exclude the unnecessary occupation of a transmission channel, by detecting a signal on a sonobuoy side to store the presence of the signal and using the transmission channel preferentially to the inquiry from a monitor station. CONSTITUTION:The underwater sound obtained by receiver 1 is amplified by an amplifier 2 to be sent to a change-over device 3 and a frequency analyser 6. The analyser 6 performs the analysis of frequency to send the analytical result to a signal detector 7 which is turn detects the level of the spectrum protruding from the circumferential noise in the frequency analytical result in order to detect spectrum sound.
