Title: Electromagnetic system flow-rate control valve
Inventor: OOYAMA TEI
IPC: F16K39/02
Filed: 1980-04-01
Abstract: PURPOSE: To permit the flow-rate of the fluid which flows through a valve seat to be controlled nearly linearly according to the current value given to a magnetic coil, by allowing the rate of increase of the area of the opening which is formed with the valve and a guide to increase gradually according to the shift of the control valve.  
     CONSTITUTION: When the current from a DC power source is given to a magnetic coil 11, the magnetic flux of the coil 11 passes through a motor housing 10, fixed core 12, movable core 15 and a yoke 13, and each attractive force which corresponds to the current value is generated between the inner peripheral surface of the yoke 13 and the outer peripheral surface of the left end part of the core 15 and between the concaved part 12b of the core 12 and the convex part 15 of the core 15.  At this time, a shaft 14 and the core 15 are shifted rightward in proportion to the  attractive force corresponding to the current value by the action of a spring 22. Further, owing to the rightward movement of a poppet valve 31, the rate of increase of  the area of the opening formed by the poppet valve 31 and a guide 30a increases  gradually and the decrease of the flow rate of the air from a chamber R 2  to a chamber R 1  due to the decrease of the differential pressure generated between both chambers R 1  and R 2  is corrected.

Title: Signal distortion compensating device
Inventor: KAJIWARA NORIO
IPC: H04N5/38
Filed: 1978-04-14
Abstract: PURPOSE: To ensure the easy compensation for the distortion of all levels caused by the main amplifier by providing the amplitude limiter to secure the distortion to the large amplitude part.  
     CONSTITUTION: The characteristics like (d) is obtained via amplitude limiter 13 containing the large amplitude part added and in correspondence to the input/output characteristics (a) of main amplifier 10. While the characteristics like (b) is obtained for the minor amplitude part via mimic amplifier 14. Thus, the distortion analogous to that of amplifier 10 can be generated easily, thus ensuring the ideal compensation for the distortion. Then in the case of signal (a') which is amplitude-modulated by the color TV signal, the distortion like (b') is generated for the output waveform of amplifier 10 when signal (a') did not pass through the distortion compensating device. But the signal led to limiter 13 after distribution through 1st and distributors 4 and 12 is led out in the form of output (c') which is distored by the amount equivalent to the synchronous signal component of large amplitude and then introduced into amplifier 14 to be amplified. At the same time, the distortion is generated also at the video signal part of minor amplitude to obtain the waveform analogous to waveform (b'), which is then applied to comparator 18. Thus, the distortion of amplifier 10 can be compensated.
