Title: Underwater detection display
Inventor: YOSHIOKA TAKASHI
IPC: G01S15/42
Filed: 1982-03-29
Abstract: PURPOSE:To achieve a higher detection performance by providing a parallel entry function for indicating images in a specific directive bearing in a time sequense from the past on a cross-section with a sectional image on a display when a specific cross-section is detected underwater altering the directive bearing in a sequentially scanning manner. CONSTITUTION:A transmission pulse of a transmitter 1 is introduced to a transmitter/receiver 3 comprising a plurality of vibrators arrayed in an arc via a switch 2 and an ultrasonic pulse is transmitted underwater each time a transmission pulse is applied. A wave signal received is introduced into a time series circuit 4 via the switch 2 and a time series action is performed based on a bearing counter 5. The bearing counter 5 specifies the bearing of a wave beam received reaching the transmitter/receiver 3 while a distance counter 8 specifies the distance to the reflection source. Counts of the counters 5 and 8 are converted to positions on the XY rectangular coordinate with a coordinate converter 9 and memorized into a memory circuit 15 via an address switch 14. Thus, time-based detection information covering the entire detection range is indicated at rows 1-n of display pixel trains on a CRT display 32.

CONSTITUTION: A packing 7 between a nozzle body 3 and a nozzle holder 6 is provided with a piston chamber 36 to contain a piston 18 at the upper end of a needle 2. The inside diameter of a piston chamber 36 is slightly lower than the outside diameter of the piston 18 and a damper chamber 36a is arranged therebelow. The packing 7 has a communication passage 35 to open and close a damper chamber 36a and a communication passage 35 is opened and closed by a spring seat 31. The spring seat 31 has a spring seat press member 32 and when a movement amount of the piston 18 is higher than a lift amount PL, the communication passage 35 is opened through push by the spring seat press member 32.  Reversely, when a movement amount of the piston 18 is lower than the lift amount PL, a spring seat 31 closes the communication passage 35 through the force of a second spring and a damper effect is produced. A damp distance is adjustable by the prelift amount PL. A damper effect is easily eliminated and checking of performance is facilitated.

Title: Digital costas loop circuit
Inventor: KITA SACHIKAZU
IPC: H04L27/227
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To realize a quick carrier recovery with a comparatively simple circuit. SOLUTION: A phase difference detection circuit 12 detects a phase difference of an output of a complex multiplier circuit 11. A loop filter 13 filters the detected phase difference and gives the result to an NCO 15. The NCO 15 adjusts the sine data and cosine data fed to the complex multiplier circuit 11 on the basis of the phase difference supplied from the loop filter 13 and whose high frequency component is cut off. On the other hand, the phase difference detected by the phase difference detection circuit 12 is also fed to a phase error generating circuit 14. The phase error generating circuit 14 generates actively a phase difference that is changing sequentially when the phase difference is large and gives it to the NCO 15. Thus, when the phase difference is large, the sin data and the cosine data are largely changed independently of a characteristic of the loop filter 13.
