Title: Pll circuit
Inventor: TAKEYAMA YOSHINOBU
IPC: G03G15/04
Filed: 1989-01-09
Abstract: PURPOSE:To evade a discontinuous input voltage or a large ripple with respect to a voltage controlled oscillator when the gain is varied by connecting an amplifier whose gain is varied depending on a voltage difference between an output voltage from a low pass filter and a reference voltage between the low pass filter and the voltage controlled oscillator. CONSTITUTION:A voltage follower 8 and an amplifier 9 are connected between an LPF 3 and a VCO 5. After a voltage signal from a PD 2 in response to a phase difference between a reference input signal Sr and a feedback signal Sf is smoothed by the LPF 3, a voltage V0 is obtained from the voltage follower 8. Then the signal is amplified via the amplifier 9, the resulting voltage is inputted to the VCO 5 as the voltage Vin. Since the gain G of the amplifier 9 is varied by a voltage difference between the output voltage V0 and the reference voltage Vref from the LPF 3, the gain change of the amplifier 9 depending on the reference signal input and on the continuity is smoothed.

IPC: G01N25/14
Filed: 1978-01-14
Abstract: PURPOSE: To realize accurate concentration measurement, keeping the flow rate constant, and preventing disturbance of control state due to noise component, by using a level detector having hysteresis in its inverting characteristics as a detector to detect the outout of the flowmeter.  
     CONSTITUTION: The output signal of a flow meter 4 is fed into a recording device 11, and is also fed into a level detector 13 through an amplifier 12. The device is constituted so as when the output signal P o  of the amplifier 12 changes in the direction to go below the first set level V 1  as shown in figures (a) and (b), an output Y is sent out; when changing in the direction to go beyond the second set level V 2 , an inverting output X is sent out. In this constitution, since a hysteresis is provided in the inverting characteristics of the output, the output of the detector 13 introduces signals X, Y into a controller 7, which energize a blower 6 and a heater 5, respectively. But, even if the output signal from the flow meter 4 contains noise component, heating and cooling may not be repeated at other than necessary points. Therefore, accurate measurements may be achieved without disturbance of the control form due to noise.
