IPC: H03L7/06
Filed: 1986-10-24
Abstract: PURPOSE:To improve S/N and to shorten a phase recovery time by counting the phase difference between a reference input clock signal and an internal clock signal as the number of cycles of a reference frequency signal and varying the frequency division ratio of a variable frequency dividing circuit acoording to the counted value. CONSTITUTION:A phase comparator PFC compares the phase of the reference input clock signal phis1 with the phase of the internal clock signal phis and holds a 1st phase difference signal uo or a 2nd phase difference signal do at high level for a time corresponding to the phase difference. A frequency division ratio control circuit FDC counts the time widths of the phase difference signals uo and do sent from the phase comparator PFC as the number of cycles of the reference frequency signal phio and holds a 1st phase control signal up or a 2nd phase control signal down at the high level for a frequency division period equal to the counted value. Consequently, the frequency devision ratio of the variable frequency dividing circuit VFD is varied by a frequency division period corresponding to the phase difference between the reference input clock signal phis1 and internal clock signal phis2 to correct the phase at high speed without any waste.

Filed: 1989-09-29
Abstract: PURPOSE:To supply liquid suitably by an amount corresponding to a container, though its volume is not known, by controlling the drive of a liquid discharger on the base of differences between the height of the container detected by a height detecting means and the level of liquid in the container detected by a liquid level detecting means. CONSTITUTION:A height detecting means 15 has a variable resistor 25 which varies resistance value corresponding to the vertical movement of a projection 23 to contact with the top surface of a container 19, whereby the resistance value which corresponds to the height of the container 19 is provided to a control circuit 11. A liquid level sensor 21 detects the liquid level in the container 19 on the base of time period from oscillation of ultrasonic wave to receipt of its reflection from the liquid surface. When the container 19 is put under a liquid outlet 17, the control circuit 11 obtains the height of the container 19 from the output from the variable resistor 25, and calculates a height, for example, of 80% of the container height as a liquid supply finishing level. A start switch 9 is turned ON. Then the control circuit 11 drives an electric pump 5 to supply liquid to the container 19, while making an ultrasonic sensor 21 survey the liquid level rising in the container 19. If the control circuit 11 is informed by the output from the ultrasonic sensor 21 that the liquid level has reached the calculated liquid supply finishing level, it stops the drive of the electric pump 5 to stop the liquid supply.

Title: Active phase calming target highlight detector and detection of target by active phase calming
Inventor: JIERARUDO EMU KAARUSON
IPC: G01S15/42
Filed: 1989-09-29
Abstract: PURPOSE: To realize highly reliable detection in an active sonar by combining differential phase information and amplitude information. CONSTITUTION: Instantaneous phase has an angle θi of difference between a pair of receiving phase beams 11, 21. This data stream is fed directly to an evaluation unit (central value filter 56) and a subtractor 58. Output ϕi from the subtractor 58 generates measurements of instantaneous phase jitter |ϕi|and local phase variance σ<2> ϕi over an appropriate time interval and the measurements are employed by a phase detector 60. The phase jitter |ϕi| and phase variance σ<2> ϕi are then compared, respectively, with threshold values and when they are smaller than a predetermined detection threshold values Tϕ and Tvar (i.e., T<2> vϕi), a phase detection binary signal detPi is generated and outputted from the detector 60. Output detMi from a magnitude detector 66 is delivered to a combination unit 68 and, in the simplest case, the combination unit 68 performs AND operation on the outputs detMi and detPi thus performing phase smoothing detection.
