Abstract: PURPOSE:To obtain a stable picture by adopting the constitution that a pulse width of a vertical synchronizing signal inputted together with red, green, blue signals and a horizontal synchronizing signal is suppressed to a prescribed width or below so as to prevent distortion from being generated at the upper part of the screen. CONSTITUTION:The vertical synchronizing signal (V pulse) is inputted from a terminal (8) of an eight-pin input terminal 1 of RGB. A V pulse is impressed to a base of a transistor (TR)5 via a resistor 3. The V pulse from the terminal (8) is inverted by the TR5, differentiated by resistors 6, 8 and a capacitor 7 and impressed to a base of a TR9. The differentiated V pulse is inverted by the TR9 and impressed to a waveform shaping circuit 2. The amplitude of the V pulse is limited to a prescribed width (nearly 0.4msec) by passing it through a differentiation circuit. Then even if the pulse width of the V pulse to be inputted is very wide, the signal impressed to the horizontal synchronizing circuit enters the circuit after 0.4msec from the start (upper part) of the screen and a horizontal synchronizing AFC circuit is activated, and then the operating response of the AFC is quickened, skew distortion at the upper part of the screen is avoided and stable screen is attained.

Abstract: PURPOSE: To obtain a compact and light-weight variable angle ultrasonic probe driving circuit, by supplying the stroke setting output and the scan center angle setting output to the comparator circuit and then feeding the output of the circuit back to the stroke setting side.  
     CONSTITUTION: In case rotor 2 has the reciprocal motion with θ c =-45° and θ s = ±15° each along with switches 13 and 12 at contacts C-1 and S-1 each, scan center angle θ c  becomes positive at -30°. In such case, the motor shifts the contact of the potentiometer to the negative side. And output E 0  of comparator circuit 10 becomes negative at -60°. Thus the motor shifts the contact of the potentiometer to the negative side. And output E 0  becomes positive at -30°, and the motor shifts the contact of the potentiometer to the negative side to draw the loop of 31 continuously. Thus loops 32, 33 and 34 are drawn continuously with the combinations of contacts C-2 and S-2, C-3 and S-3, and C-4 and S-4 respectively. As a result, the automatic driving is possible for the probe through a simple constitution of  one unit of the comparator circuit and the switching circuit each.
