Title: Color recorder
Inventor: FURUTA HIDEYA
IPC: G03G15/01
Filed: 1986-04-11
Abstract: PURPOSE:To eliminate the positional deviation of an image to form high definition color image even if the speed of a driving roll is varied, by setting dimensions of an electrostatic latent image area of each color formed on a belt-shaped photosensitive body to integer-fold peripheral length of a photosensitive body driving roll. CONSTITUTION:Optical images R, G, and B on a belt-shaped photosensitive body 6 which are subjected to color separation are developed as a C image, an M image, and a Y image by a cyan developing device 9c, a magenta developing device 9m, and a yellow developing device 9y respectively in accordance with movement in the direction of an arrow A of the photosensitive body, and developed images are transferred on a transfer paper 10 one over another in order of images Y, M, and C. The belt length between transfer points X and Y and transfer points Y and Z is b+l+a, where l is the length of each latent image area on the photosensitive body and (b) is the length of inter-area spaces and (a) is the length between transfer points. If a transfer paper 10 is carried at a certain speed, transfer deviation does not occur; and therefore, l+b is set to integer-fold peripheral length of a driving roll 7i. Thus, image deviation is eliminated by repeating exposure at the rotation period of the roll 7i to obtain high definition color image even if the speed of the roll is varied.

Title: Electronic zooming processing unit and its method
Inventor: TAKANE YASUO
IPC: H04N5/228
Filed: 1995-04-07
Abstract: PURPOSE: To execute arithmetic processing successively from the end of a picture without deviating the center position of a processed picture from an original picture in the case of enlarging/reducing a video signal expressing a picture by digital operation. CONSTITUTION: A processing start picture element determining part 10 determines a processing start picture element based upon the center position of an original picture. An integer part is applied to a picture element input part 18 to read out the start picture element. A correction value calculating part 12 calculates the center deviation of the processing start picture element from the decimal part of an arithmetic result and applies the deviation to an interpolation coefficient computing part 14. Thereby the position of the picture element to be found out is corrected by the center position correcting value applied to an interpolation computing part 16 as an interpolation coefficient and the picture element value of a picture end is found out on the corrected position based upon a picture element inputted from a picture element input part.  Then the computing part 14 successively adds distances with equal intervals calculated based upon zooming magnifation (r) to the initial position to execute the interpolating operation of other picture elements. Consequently arthmetic processing from the end of a picture element can be effectively executed without generating a deviation from the center position.

Title: Speed control device for rolling mill
Inventor: NOGUCHI MASAHARU
IPC: B21B37/46
Filed: 1985-04-19
Abstract: PURPOSE:To make possible the stable rolling at different circumferential speeds by monitoring the armature current of an electric motor for driving a rolling roll and decreasing the armature current of an electric motor for driving a rolling roll on the side where the current limit value is attained. CONSTITUTION:A current limit detecting circuit detects the current limit value when the armature current of the motor 4 for driving the lower rolling roll 2 attains the current limit value. A correction factor for the different circumferential speed is then calculated in an arithmetic circuit for the correction factor for the different circumferential speed and is outputted to an arithmetic circuit 7 for the different circumferential speed. The correction factor for the different circumferential speed and the set speed of the different circumferential speed which is the output of a setting circuit 5 for the different circumferential speed are multiplied by a multiplier in the circuit 7 and the different circumferential speed is corrected. The different circumferential speeds of the motors 3, 4 for driving the upper and lower rolls are thereby corrected and the speed difference between the rolls 1 and 2 is decreased. The armature current of the motor 4 for driving the lower roll 2 is thus made smaller than the current limit value.
