Abstract: PURPOSE:To obtain a notch-less analog vector display with a simple device, by finding the ratio of virtual resolution which is higher than grating resolution to the grating resolution and coordinates of the final point from the ratio and forming a composite line by increasing the coordinates of the final point. CONSTITUTION:The ratio D of the density of the resolution of a virtual grating which is higher than grating resolution to that of the resolution of a physically addressable grating is found in the form of an integer. Then two coordinate points of a virtual final point in a desired composition are received in the form of four veriables XA, YA and XB, YB. These variables XA-YB are given in the forms of virtual address, respectively. Then the variables XA-YB are copied to UXA, VYA and VXB, VYB, respectively and the ratio D is copied to a variable CTR. Thereafter, the variables UZA-VYB are divided by the ratio D. Results of the division by the ratio D give coordinates to a physically addressable place. Then a line is drawn between physically addressable coordinate points. Thereafter, the variables VXA-VYB are increased and the above- mentioned steps are repeated until the variable CTR becomes the D.

Abstract: PROBLEM TO BE SOLVED: To provide a uniform plasma density distribution by providing a clearance in the center of the length of each of anisotropic segment columnar magnets in a dipole ring magnet, and setting the size of the clearance to match the place of the columnar magnet. SOLUTION: Anisotropic segment columnar magnets 50 (1 to 16) are oriented, as the dipole ring magnet of a magnetic field generator, in the direction of magnetization shown in the Fig. so that a magnetic field shown by the arrow 53 is produced within the ring. Each of the columnar magnets 50 (1 to 16) has a clearance 54 provided in its center along its longitudinal direction, the sizes 55 of the clearances 54 getting smaller in areas where the strength of the magnetic field is made higher and getting larger in areas where the strength is made lower. For the gradient of the magnetic field to show a distribution in which the magnetic field gets higher in the positive direction of Y-axis and lower in the negative direction, the sizes 55 of the clearances are determined to match the places where the columnar magnets 50 (1 to 16) are placed along the direction of Y-axis.  Therefore, a plasma that is uniform over a wide range can be obtained by use of the magnetic field generator in a magnetron.

Abstract: PURPOSE:To prevent the formation of a resist film on the peripheral part of a wafer and the rear surface of the wafer by forming a frame part comprising coarse-oil resin at the peripheral part of the wafer, and applying resist on the surface of the wafer on which the frame part is formed. CONSTITUTION:A resin 12 is injected through a resin injecting port 11 of an top force 9. A frame part 7 comprising a resin is formed in a doughnut shape so as to cover the peripheral part of a wafer 6. Resist 8 which is dropped on the central part spreads in a concentric circle pattern to the peripheral part by centrifugal force when a wafer sucking pipe 1 is rotated. Since the resist 8 at the lower layer stops at the sidewall of the frame part 7, a resist film is not formed at the peripheral part of the wafer. Meanwhile, the resist 8 at the upper layer spreads on the surface of the frame part 7. Since said part is formed with coarse-oil resin 12, however, the resist does not come into contact with the frame part 7 tightly. The resist 8 is repelled and splashed away.

IPC: G06F3/12
Filed: 1990-07-04
Abstract: PURPOSE:To inform a user of the number of unprocessed pages by outputting the number of unprocessed pages stored in a data storage means through an output means. CONSTITUTION:A 2nd detection means checks whether the inputted print data is identical with an ejection command or not. If so, the value stored in a storage means is updated by a counter means. Then the print data is stored in the storage means and sequentially processed by a print means. At the same time, a 1st detection means checks whether the data processed by the print means is identical with an ejection command or not. If so, the counter means updates the value stored in the storage means. Thus the updated count value of the storage means is sequentially outputted to an output means, and the number of unprocessed pages contained in a printing device is always outputted to an output device.
