IPC: H04N9/68
Filed: 1984-06-29
Abstract: PURPOSE:To prevent the deterioration of S/N and to reduce level fluctuation of an input carrier chrominance signal in the standard mode reproduction and long time mode reproduction by using most suitably the effective dynamic range of input of an A/D convertor. CONSTITUTION:Low frequency conversion carrier chrominance signals inputted from a terminal 11 are adjusted in level by a controlling signal in a gain control amplifier 12 and outputted to an A/D convertor 13. The signals digitalized by the A/D convertor 13 are converted to two color difference signals, B-Y and R-Y, by a comb line filter 19. These color difference signals are added to data 1H before, and after removing crosstalk, modulated by a modulator. A color difference signal B-Y during burst period is outputted by a burst level detector 22, and this is compared with the reference level by a comparator 23, and consequently, gain of the gain control amplifier 12 is controlled. At this time, by making the reference level different in standard reproduction mode and long time mode, an effective dynamic range most suitable for each mode can be obtained.

Abstract: PURPOSE: To obtain a measuring appratus of velocity and rate of flow of good rigidity and sensitivity and good S/N with a simple constitution by mounting the force detecting parts which are opposedly provided on the lateral peripheral part of a columnar rigid body part by means of ?a fixing means.  
     CONSTITUTION: Force detcting parts 2 which are opposedly provided on the side face of a rigid body part 1 are insulated and sealed by means of a sealing body 3. When the force to be measured is applied alternately like the arrow X, the detection parts 2 produce the electric signal corre?sponding to the force to be measured. By detecting this signal, the force to be measured may be measured. Now, when this device C is used with a measuring apparatus of velocity and rate of flow by making use of von Karman's vortex streets and the fluid to be measured flows in the arrow Y direction of the pipeline A, then vol Karman's vortex streets are produced by a vortex producing body B, acting alternating forces perpendicular to the plane of the figure. The alternation times thereof are detected with the detection part 2, whereby the vortex generating frequencies may be detected. Since the detection parts are so provided as to directly face to the places where the force to be be measured is applied, the measuring force may be detected with good sensitivity without picking up any external noise.
