Title: Signal input system of charge coupled element
Inventor: AKIYAMA IKUO
IPC: H01L29/762
Filed: 1980-06-24
Abstract: PURPOSE:To prevent the DC level from varying in accordance with a change of a plane picture level, by installing a coupled capacitor and a DC reproducing circuit between an input signal source and a signal input gate of a charge coupled element. CONSTITUTION:A diode 51 conducts when no signal exists, and thus the current flows forward. In this case, the input impedance of an input gate 12 is high enough and a resistance 53 has a high resistance value. Thus a apapcitor 13 is charged to the polarity as shown in the figure with voltage E2-EB, where E2 is the voltage of a voltage source 52 and EB is the built potential of the diode 51. Then a video signal with the DC component lost is supplied as an input signal 16, and as a result the diode 51 conducts in the period when the input signal becomes negative to give a charging to the capacitor 13 again. After this, the input signal cahnges to the forward direction, and thus the signal source 16 is added in series with the charge voltage of the apacitor 13 for the voltage at point B. As a result, the tip of the horizontal synchronous pulse has a waveform clamped by the voltage E2-EB. Accordingly no change is caused to the DC level.

Title: Dc/dc converter
Inventor: MATSUI ATSUSHI
IPC: H02M3/338
Filed: 1981-06-05
Abstract: PURPOSE:To forcibly shift a switching transistor from ON to OFF by closing a switching element connected to the base of the transistor before the transistor automatically becomes OFF state. CONSTITUTION:When a circuit is oscillated by a power source, inputs A, B of a comparator 10 are compared based on the output of an output coil N2, and an output C is supplied to the T input of a flip-flop 20 when an input is A>B. On the other hand, a sense coil N4 detects via a detector f the inversion of a magnetization produced at a transformer T when a switching transistor Q1 is shifted to OFF state and produces an output to the flip-flop 20, which in turn produces a pulse g. A transistor theta2 is thereby driven, and a switching transistor Q which is originally ON is forcibly interrupted. In this manner, a DC/DC converter can be operated at a high frequency with less loss.
