Patent JP-S6193713-A (JP)
Title: Error detection circuit
Inventor: MURAKAMI KOU
IPC: H03K3/84
Filed: 1984-10-13
Abstract: PURPOSE:To measure accurately error number in the longest series by adding an exclusive OR circuit to correct an error in the inputted longest series. CONSTITUTION:When an erroneous signal exists at an input terminal 7 and DFF1-4 have no error, an input of an exclusive OR circuit 6 goes to logical 1. Then the added exclusive OR circuit 10 acts like inverting a signal at the input terminal 7 and inputting it to the DFF1. Since the signal at the input terminal 7 is in error, the inversion means that the error is corrected. Thus, no error appears at the output of the DFFs 1-4 and an erroneous output goes to logical 0 at a point of time other than the presence of the error at the input terminal 7. Since the erroneous output goes to logical 1 only at a one point of time to one input error, the number of errors is measured accurately.

Inventor: IZUME MASAYUKI
IPC: B41F31/04
Filed: 1986-09-10
Abstract: PURPOSE:To lessen the time required for preparation of printing and the amount of test paper, by a method wherein a plurality of ink amount regulation members are arranged compactly in the longitudinal direction of an ink original roller and the opening and shutting of an ink passage is controlled at each ink amount regulation member. CONSTITUTION:A plurality of ink amount regulation members 15 composing an ink fountain 14 are compactly arranged in the longitudinal direction of an ink original roller 12 and the opening and shutting of the ink passage 18 between the ink original roller 12 and each ink amount regulation member 15 is independently controlled at each ink amount regulation member 15. Consequently, the time while the ink passage 18 is open can be directly or indirectly controlled at each ink amount regulation member 15 and the ink amount can be easily accurately regulated independently at each position of the length direction of the ink original roller 12 i.e. of the width direction of a printing surface. Therefore, by enabling the ink amount to be numerically controlled, the time required for preparation of printing and the amount of test paper can be lenssened and made economical.

After that, a tunnel oxide film 21 is formed by a CVD of an oxide film.

Title: Halftone gravure printing plate
Inventor: SHIGETA MORI
IPC: G03F5/20
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To form the above gravure printing plate in such a manner that the various density gradients from highlight parts to shadow parts are approximately completely proportional by forming cells of the dot shapes dispersed at the number of the cells increased in proportion to the various density gradients by maintaining the depth of the cells of the highlight parts. SOLUTION: The cells (black solid parts) are dispersed to the dot shapes if the aperture rate of the cells is 2 to 32%. The cell parts connected in a groove form increase successively if the aperture rate of the cells exceeds 32%. There are drop-out parts in the cells and, therefore, the points where the cell width increases are averted even in the shadow parts exclusive of the extreme shadow parts (the aperture rate of the cells is 64%). Then, the depth of the cells obtd. by the etching method is not increased and is suppressed to the shallow depth approximate to the depth of the cells in the highlight parts. The cells from the highlight parts to the shadow parts are formed of the dot shapes dispersed at the number thereof increased in proportion to the various density gradients and the areas of the cells are proportional to the various density gradients.

Filed: 1990-08-16
Abstract: PURPOSE:To improve the picture quality visually by varying a threshold level of a discriminator by means of the coding method of a preceding frame or a preceding field. CONSTITUTION:A coding method of a preceding frame at a same position as a block to be discriminated by a movement discriminator 20 is read from a memory 21 and it is inputted to the movement discriminator 20 as a signal 22.
