Title: Synchronous control system of copying machine
Inventor: UENO HIROAKI
IPC: H04N1/32
Filed: 1980-09-25
Abstract: PURPOSE:To synchronize a picture with transfer paper, to shorten a stand-by time, and to speed up copying operation, by stopping exposure with an optical picture signal when the transfer paper does not reach a resist roller, and restarting the exposure after prescribed operation is performed. CONSTITUTION:For example, the carriage of transfere paper is delayed, and failed in synchronizing the front edge of a pictur on a photosensitive drum with the transfer paper, and a flip-flop FF1 is set. If a set signal for driving a resist roller is outputted, namely, when a differential signal is outputted from a differentiating circuit 27, an AND gate AND2 outputs a reexposure request signal RE to an exposure part and an optical picture signal PS is cut off. After prescribed operation is performed, the optical picture signal is outputted again. Thus, a reexposing function for the carriage delay of the transfer paper is provided, so a copying speed is increased without paying attention to accidental paper delay.

Title: Surface potentiometer
Inventor: SUZUKI KOUJI
IPC: G01R29/12
Filed: 1977-11-09
Abstract: PURPOSE: To convert the high impedance signals, which are induced in a measuring electrode, into low impedance signals so that they may be extracted with the use of an FET and a diode.  
     CONSTITUTION: The signals 13 of a surface 1 to be measured are fed to an FET 6 and diode 3 through a space capacitance 10 between the surface 1 and a measuring electrode 2. Even if the diode 3 is under shielded condition as an initial condition, the diode side potential of the capacitance 10 approaches the bias voltage E 0  which is impressed upon a terminal 4. If the output side potential of the capacitance 10 is in the vic-nity of E 0  at the point A of signals 13, the output side of the capacitance from A to B approaches the lower potential. When that output side potential becomes lower than E 0 , however, the diode 3 becomes conductive so that the output potential at point B takes the value of E 0 . From point B to C, the diode 3 is inconductive so that signals having the same waveform as that of the signals 13 are generated at the output side. Thus, similar signals to those signals 13 can be generated at the gate of the FET 6 so that the output having a stable low impedance can be generated at the source or drain.
