Title: Tracking antenna device
Inventor: MAEDA MITSURU
IPC: G01S3/14
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a tracking antenna device which can secure a stable tracking state. SOLUTION: When a power supply is applied, a search mode starts to search the direction of a satellite after calculating the drift correction value from the output of a gyrosensor 9 before an azimuth direction drive mechanism part 8 starts. When the output of a reception detection circuit 5 is turned on, the search mode is shifted to an initial tracking mode where the amplitude speed is higher than the ordinary speed for a turning action done in the step track tracking azimuth direction. The drift correction value is updated in the initial tracking mode, and this mode is shifted to an ordinary tracking mode of a low amplitude speed of the preceding turning action when a switching part 10 decides that the accuracy is improved up to a level where no problem is caused.  When the ordinary tracking mode is once set, this mode is always secured as long as the output of the circuit 5 is turned on again even if the output of the circuit 5 is turned off and the tracking mode is shifted to the search mode. Then the initial tracking mode is never set again.

Title: Fm modulator with pll circuit
Inventor: SUGINOSHITA FUMIYASU
IPC: H04N5/40
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a compact FM modulator which excels in the stability of frequency and can secure a fast phase clock at the application time of a power supply without adding any circuit of an LPF, a switch, etc. SOLUTION: An FM modulator has a coupled circuit 3 between an active loop filter 2 constructing a PLL circuit and a VCO(voltage control oscillator) 4. The circuit 3 consists of a capacitor C1 , and resistors R1 and R2 . The control signals that undergone the voltage division through both resistors R1 and R1 , the DC bias power output and the video signal passed through the C1 are mixed together and applied to the VCO 4. Then the circuit 3 functions as an LPF that cuts off the comparison angular frequency ωref for the control signal of the PLL circuit and also functions as a DC cutter which eliminates the DC level variance for the video signal respectively. Furthermore, the DC bias power voltage is divided by a resistor and applied to the VCO 4, so that the initial value of voltage applied to the VCO 4 is equal to the value close to the voltage level that is set in a phase lock mode. At the same time, both control and video signals are mixed together at a high impedance and applied to the VCO 4.
