Title: Serial controlled constant voltage circuit
Inventor: HAGIWARA SOUJIROU
IPC: G05F1/56
Filed: 1994-02-04
Abstract: PURPOSE:To stabilize the output voltage against load variation and reduce a screen flicker by supplying the bias of a voltage control drive circuit by a peak detector. CONSTITUTION:A voltage which is divided by bias resistors 10 and 11 with a voltage having its peak rectified by the diode 20 and capacitor 21 of the peak detector 9 is smoothed by a capacitor 12 and applied. Consequently, the base voltage of a drive transistor(TR) 13 is stabilized, the output voltage of the voltage control drive circuit 4 becomes stable, and the output voltage of the output voltage control circuit 3 does not vary. Therefore, when an AC input voltage drops, the output voltage is prevented from varying owing to the load variation. Consequently, the output voltage can be stabilized against the load variation and the screen flicker is reducible.

Title: Waveform converter circuit
Inventor: BISE TOMOKAZU
IPC: H04B3/32
Filed: 1979-02-08
Abstract: PURPOSE:To realize the miniaturization of the capacitor for the waveform converter circuit which prevents occurrence of the spike noise, by increasing equivalently the resistance value at the time constant part. CONSTITUTION:With supply of signal H to input 100, signal L is obtained from output 110. In this case, the output impedance of input circuit 30 is set extremely larger than that of the amplifier circuit consisting of intermediate transistor 40 (R10>>R20). As the collector of output transistor 50 is connected via capacitor 90, output signal V0 is expressed in the form of the output of the Miller integrating circuit featuring the time constant of 90.R10. Accordingly, the whole circuit can be suitably integrated since C90 can be minimized under the conditions of R10>>R20. Also the diode can be used as the capacity in place of coupling capacitor 90.
