  • Publication number: 20060011834
    Abstract: High resolution observation is achieved at a low acceleration voltage of 5 kV or below under a high pressure condition of a sample chamber. A sample chamber has a double structure and an inner sample chamber for keeping low vacuum is arranged inside an outer sample chamber having high vacuum. A relatively high negative voltage such as ?1 to ?9 kV for decelerating electrons immediately before a sample is applied between the outer sample chamber and the inner sample chamber. When an incident electron beam passes through an objective lens, an electron beam keeping high energy and having small aberration is formed and is decelerated immediately before the sample to acquire high resolution at a low acceleration voltage.

  • Patent number: 4684978
    Abstract: Color-separated signals, which are adapted to fabricate color-separated printing plates, are subjected to ICR processing by the hand re-touching technique while watching them on a color monitor (which is employed to simulate printing results), thereby avoiding occurrence of localized irregularity in color tone. The method of this invention facilitates the ICR processing in a hand re-touching manner and at the same time, permits immediate observation of correction results while watching the progress of the processing on the color monitor.

  • Patent number: 4673989
    Abstract: A method and apparatus for recording plural images with desired layout by an image reproducing scanner in which frames on which images to be reproduced are moved relatively to an optical axis by maintaining a layout sheet which represents area frames on a projecting plane of a projector. The original pictures to be reproduced are mounted on a movable and rotatable original picture holder along a plane intersecting perpendicularly with the optical axis. The desired areas on which the original pictures are projected are focused by adjusting magnification ratio etc., and a pick-up scanning drum and the above described data are stored as control data. Repeating the above described, the pick-up drum on which the original picture are loaded is set up so that reproduced patterns may be recorded according to the control data.

  • Patent number: 4656505
    Abstract: A method for color correction in the process for reproducing a picture in which color separation picture signals obtained by photoelectrically scanning an original picture are converted into picture signals which correspond to four printing color inks including a black ink therein to produce respective reproduction pictures for plate making corresponding to each of the color inks. A picture signal which corresponds to a black ink is produced according to gray color components obtained from B, G and R signals of the original picture, and according to chromatic color components obtained by subtracting neutral color components from said B, G and R signals. Color separation picture signals corresponding to other color inks, and deficiency in reproduction density of the black ink to be used in a black print is corrected by said other three color inks.
