Title: Electrophotographic device
Inventor: KAWAKAMI MASANORI
IPC: G03G15/043
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To make the size error of images on both sides small and to obtain a stable image by making paper carrying speed at the time of transferring the image on the 2nd side of paper lower than the paper carrying speed at the time of transferring the image on the 1st side of the paper by an amount corresponding to the reduction rate of the paper at that time. SOLUTION: The image formed on a photoreceptor 30 is transferred on the 1st side (front surface) of the paper P in a transfer part 11. The transferred image is thermally fixed in a thermal fixing device 12. In the case of printing on both sides of the paper P, the paper P on whose 1st side the image is thermally fixed is carried to a double-sided unit 20. Since the paper P is reversed from the front surface to the back surface in the unit 20, the image is transferred on the 2nd side (back surface) of the paper P in the transfer part 11 and the paper P on which the image is transferred passes through the fixing device 12 so as to thermally fix the image.  The paper carrying speed at the time of transferring the image on the 2nd side of the paper P is made lower than that at the time of transferring the image on the 1st side of the paper P by the amount corresponding to the reduction rate of the paper P at that time.

Title: Discharge circuit to dc input line
Inventor: MIYAZAKI TAKAHIRO
IPC: H04M19/08
Filed: 1987-08-12
Abstract: PURPOSE:To prevent malfunction due to noise by connecting an input set to a ground level and an output set to a logical ground level by a resistor having a prescribed resistance in a terminator for a telephone switchboard or the like. CONSTITUTION:An output set with logical ground level E of the secondary winding Ns of a transformer 20 and an input set with a ground potential G of the primary winding are connected by a resistor R having a resistance, e.g., 510kOMEGA. As a result, the electric charge stored in the secondary winding is discharged to the ground of the primary winding via the resistor R. Thus, no electric charge is stored in the secondary winding and the logical circuit is not malfunctioned due to the stored electric charge. Moreover, since the resistor R has a high resistance value, an external surge inputted superimposingly on the power line does not almost give effect onto the secondary winding.

Abstract: PURPOSE:To facilitate the checking of a negative, by processing the electric signals obtained by image picking up plural sheets of printing negative film with TV cameras of the same number as the film to display them at a monitor TV and at the same time producing pseudo picture signals to exchange them with the signals supplied from the TV cameras. CONSTITUTION:The negative films 2-5 correspond to 4 colors Y (yellow), M (red), C (deep blue) and BL (black) respectively which are arranged on a holding plate 1 and then image picked up by TV cameras 7-10 through zoom lenses 7'-10' in the form of images of desired sizes in order to obtain signals Y, M, C' and BL. The white and black levels are controlled 12 by an electric signal processing circuit 11 and amplified by a matrix circuit 13 to be converted into 3 primary colors R, G and B. These signals are fed to a monitor TV 14 and synthesized to a color to be displayed. If you want to erase a certain color, the pseudo signal is produced by setting the level of the picture signal obtained when the halftone spot density of the negative film is set at zero for the relevant color equal to the level of the blanking signal. This pseudo signal is exchanged to the signal of the camera of the relevant color. As a result, the propriety can be easily detected for the conjecture of each negative film.
