Patent JP-H0335169-A (JP)
Title: Pulse amplitude data sampling circuit
Inventor: NISHIMOTO MASAYOSHI
IPC: G01R19/00
Filed: 1989-06-30
Abstract: PURPOSE:To enable accurate sampling even by a noisy system by deciding the end of input pulses by detecting the input pulses being lower than a threshold level for longer than the period of the prescribed number of clocks, and inhibiting rising differential pulses from being generated again until the pulse end is detected. CONSTITUTION:When the input pulse signal 1 is inputted to an A/D converting circuit 3, an (n)-bit digital value 4 is obtained every time a clock pulse 2 is supplied and a comparator 5 compares the digital value 4 with the threshold level 23 to discriminate between a noise and a signal, thereby outputting a signal detection signal 6. Then an AND gate 10 detects the signal 1 being lower than the level 23 for longer than the period of the prescribed number of clocks and outputs an input pulse end signal 11 to set an FF 12. Then even if the level of the signal 1 becomes lower than the level 23 temporarily under the influence of a noise, the rising differential signal is not outputted although the level 23 is exceeded until the FF 12 is set, thereby preventing pulse amplitude data from being sampled newly.

Title: Acoustic position measuring apparatus
Inventor: TAKENOUCHI TAKEJI
IPC: G01S15/74
Filed: 1985-08-01
Abstract: PURPOSE:To obtain positional information for navigation control of a submarine with an accurate estimate of the position during the navigation, by calculating the estimated position of the submarine to determine a forecast linear distance to a transponder under sea for the correction of errors in the position thereof. CONSTITUTION:A motion detecting means 1 transmits angle/angular velocity/ speed signals 101, speed signals 102 and angle/angular velocity signals 103 in three axes of a submarine. A coordinates converter 2 performs a coordinates conversion of the combination of the signals 102 and 103 or one of the signals 101 and feeds the results to a data processor 5 as ground speed signal 104. A question sonar 4 emits sound wave signals 111A-111C under sea through a transmitter/receiver 4B from a transmitting/receiving processor 4A and after they reaches transponders 6A-6C, response signals 112A-112C thereto are fed to the processor 4A via the transmitter/receiver 4B. On the basis of the propagation time of sound waves under sea, the distance from a ship is calculated and the unit 5 corrects errors in the position of the ship using the resulting distance signal 106, the signal 104 and the depth signal 105 from a depth meter 3.

Filed: 1982-10-01
Abstract: PURPOSE:To prevent a mesh strand group from generating the cut of its mesh strand even if the mesh sheet is formed into a curved surface-like configuration after said sheet is fixed to its ring, by deforming the configuration of an open hole-like mesh which is formed by the mesh strand group and the crossing part, so that the mesh strand group may endure its elongation.
