Title: Superheterodyne communication equipment
Inventor: ONO MASAAKI
IPC: H04B1/40
Filed: 1984-06-07
Abstract: PURPOSE:To stabilize the center frequency of reception IF against temperature change by selecting a ratio of temperature characteristic of an oscillator for carrier oscillating circuit at transmission side and an oscillator for local oscillator circuit at reception side equal to the ratio of frequencies of both the oscillators. CONSTITUTION:For example, an LiTaO3 is used for the 1st vibrator used for a carrier oscillating circuit 2 of a transmission circuit 1 and a frequency at T deg.C is taken as f1 and its temperature coefficient is taken as alpha1. LiTaO3 is used similarly for the 2nd vibrator used in a local oscillating circuit 8 at the reception side, the frequency at T deg.C is assumed as f2 and its temperature coefficient is assumed as alpha2. In such a case, the cut angle of the X cut of an LiTaO3 is selected so as to be alpha1/alpha2=f1/f2. Thus, the oscillation with wide frequency band width is attained and even when temperature change exists, the center frequency of an IF amplifier circuit 10 is kept always stably.

Title: Power amplifier circuit
Inventor: OKANO YASUSHI

Filed: 1995-05-17
Abstract: PURPOSE: To prevent the oscillation of the power amplifier circuit controlled by a gate bias voltage by inserting an oscillation prevention circuit to a gate bias circuit of a final stage FET of the power amplifier circuit to suppress generation of a leakage current between the gate and the source. CONSTITUTION: When an output power of the power amplifier circuit is controlled by a gate bias voltage of a gate bias circuit 3 of a final stage FET 1 and a leakage current Igs is generated by the increase in an output power of the pre-stage FET, the current Igs flows to a source and to an oscillation prevention circuit 5 via resistors R3 , R4 of the circuit 3. The circuit 5 suppresses the leakage current Igs with a coil L1 and a Q dumping resistor R2 to prevent the oscillation. This is because the gate-source voltage is apparently increased more than that of a conventional amplifier circuit by the suppressed leakage current Igs.

Abstract: PURPOSE:To eliminate flickering on the screen by using a prescribed correction coefficient when the number of a picture element is fluctuated over a prescribed range so as to correct gradation of a luminance signal thereby obtaining a signal with contrast. CONSTITUTION:A luminance signal subjected to A/D conversion 1 is branched, one is fed to a gamma correction circuit 7 and the other is fed to a gradation detection section 2.

First and second comparator sections 5, 11 compare with respective reference data in 1st and 2nd storage sections 4, 10 and a prescribed correction coefficient of a table selection circuit 6 is selected and the gamma correction circuit 7 corrects gradation of the luminance signal. In the gamma correction, when there is fluctuation repetitively in which the number of picture elements is frequency exceeding or decreasing the vicinity of the 1st reference value, whether or not the range of fluctuation exceeds a prescribed width by using a 2nd reference value is discriminated and when the prescribed width is not exceeded, gamma correction is not executed.
