Title: Automatic frequency control circuit
Inventor: SENUMA TOSHITAKA
IPC: H03J7/06
Filed: 1990-01-22
Abstract: PURPOSE:To suppress an event that the oscillation frequency is fluctuated with a period of an input signal by providing a peak holding circuit between a low pass filter and a voltage controlled oscillator. CONSTITUTION:The peak holding circuit 5 is provided between the low pass filter 4 and the voltage controlled oscillator 6. In this case, an error current C outputted from a detection section 3 in the locking state flows to the low pass filter 4 and a triangle shaped dent is caused at an output waveform naturally and a level change of the waveform part of the peak holding voltage corresponding to the dent is decreased by the action of the peak holding circuit 5 and the fluctuation of the oscillation frequency of the voltage controlled oscillator 6 is reduced. Thus, the fluctuation of the oscillation frequency of the voltage controlled oscillator with a period of the input signal is suppressed and an output whose frequency is made stable is obtained.

Title: Waveguide-type branching circuit
Inventor: AOKI KATSUHIKO
IPC: H01P1/16
Filed: 1979-02-06
Abstract: PURPOSE:To secure the phase compensation over a wide band by giving the phase difference of pi between two branch waveguides which connect two main waveguides. CONSTITUTION:Short-circuit waveguides 4a, 5a, 4b and 5b plus branch waveguides 6 and 7 are provided to main waveguides 1a and 1b. Then the transmission phase of waveguide 7 is set to delay by pi to transmission phase f1 of waveguide 6 for the electric wave in the low-frequency band. Here in case the wave in the high-frequency band is put in through 1st end faces 10a and 10b of waveguides 1a and 1b each, no higher-order posture is produced owing to coupling hole 8 and filter 9. Thus the wave can be transmitted to the 2nd end face with no effect given to the polarized wave. With application of the X-axis polarized wave of the low-frequency band to waveguide 1a, the X-axis polarized wave is turned into the Y-axis direction polarized wave component when tranmitted into waveguide 1b. As a result, the phase compensation becomes possible over a wide band.
