Title: Image forming device
Inventor: SAKAGUCHI KAZUYUKI
IPC: G03G15/36
Filed: 1995-01-30
Abstract: PURPOSE: To prevent erroneous manipulation by making it unnecessary for an operator to be corcious of the direction of paper in an image rotation function. CONSTITUTION: This device is equipped with a control means 4 for determining, in automatic paper selection mode, form based on the size of the image of an original, set magnification, and the presence or absence of 90 deg. image rotation, and display means 6 and 7 for displaying the size and direction of the determined paper. In a 90 deg. image rotation operation, the direction of the form is not displayed but only the size of the form, therefore an operator is not concious of the direction of the form.

Title: Semiconductor device
Inventor: NISHIMURA YASUMASA
IPC: H01L21/82
Filed: 1989-01-20
Abstract: PURPOSE:To prevent the cut position deviation of a fuse link by forming a position deviation detection test pattern of an alignment mask on the same layer as a fuse link, and forming the alignment mark on the uppermost layer of a semiconductor element. CONSTITUTION:A fuse link 3 of function blocks 2a, 2b arranged in parallel on a semiconductor element 1a is cut by the following sequence. After a laser trimmer detects an alignment mark 17, fuse link patterns 11, 12 in the X and Y directions are cut based on coordinate data like mask data. The deviation of cut position in the above process is measured with measuring scales 18, 19, thereby correcting the mask data. According to the corrected coordinate data, the cut position of the link 3 is calculated. As a result, the cut position of the link 3 can be accurately set, even when the mark 17 and the link 3 are arranged on different layers, and formed so as to be displaced from specified positions.

Title: Binary coding method of image data
Inventor: TAJIMA HIROAKI
IPC: H03M5/12
Filed: 1985-01-28
Abstract: PURPOSE:To obtain a reproduced image which is faithful to its original image and superior in gradation characteristics by performing space frequency processing which emphasizes the high frequency component of digitized image data and converting the processed image data into a binary signal on the basis of a threshold value. CONSTITUTION:An unsharpness masking method is employed as a simple method for high-frequency range emphasis. This is the method for improving the appearance of an image by emphasizing the edge of a dot image during printing. In this invention, this method is attained digitally. Picture element data (x) in the center of a nXn-dot matrix to be edge-emphasized is processed by x'=x+ k(x-Q). In the equation, (k) is the weight coefficient of the edge emphasis and Q is the mean value of nXn picture element data in the nXn matrix. This arithmetic processing is carried out to obtain edge-emphasized picture element data. When this image data is converted into binary data, the threshold value is increased or decreased by a constant value according to whether picture elements which adjoin to an object picture element of binary coding and are already determined between black and while are black or white.
