Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To form a high-quality image over a long term by preventing the scattering of a character and a line image caused on an intermediate transfer belt.

IPC: G01N23/203
Filed: 1986-12-16
Abstract: PURPOSE:To decrease the number of magnets for proton beam deflection by forming a proton beam incident point for a magnet, an emitting point of beams, a center of circular orbit beams in a magnet, and a rectilinear locus of beams after emitted from the magnet, on the same flat plane. CONSTITUTION:Proton beams after being scattered become incident to a magnet 1 at a J point. Beams of low energy advance along a locus of R1 in a small radius of curvature and leave a magnetic field at a point K Beams of high energy advance along a locus of R2 in a large radius of curvature and leave the magnetic field at a point N. When centers of loci R1 and R2 are made to be O1 and O2, points J, O1, O2, N, and N are on a reference beam surface. After the proton beams leave points K and N, the beams advance along rectilinear loci T1 and T2, and also they are on the reference beam surface. A slit 5 of an analizer G is disposed to cross the standard beam surface. The proton beams enter the analizer G through the slit 5 and drop in either channel of a position detecting part 4. The number of magnets can be decreased into one by this composition, and so a device can be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To convert a resolution of a binary image and then of a multi-value image with excellent resolution and gradation by generating a difference between an N(>=2)-value signal and a signal after an arithmetic operation for a difference signal for a pixel and using the difference signal when surrounding pixels not converted are converted. SOLUTION: This method converts, e.g. received binary image data into, e.g. binary image data with different resolution, and image data for converting resolution of the image are received via an input interface 2. A CPU 1 applies binary processing to an arithmetic result of a sum of a value resulting from weight-summing each adjacent pixel value before conversion at an image position after the conversion in terms of a distance and of a value resulting from weight-summing a difference signal produced in surrounding pixels of a pixel after the conversion attended with binary processing in terms of a distance with respect to a prescribed threshold value. The difference signal between the binary signal and the arithmetic result is produced as a difference signal for a pixel and used for the conversion of surrounding pixels that are not converted.
