Title: Device and method for image formation
Inventor: TAKEKOSHI NOBUHIKO
IPC: B41J2/01
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To make the manual feed direction of a turned over sheet easy to know, and prevent conveyance failure and staining of the sheet from occurring by using the sheet, which has a characteristic to expand to an image-forming means side before an image formation, and also, wherein a mark to indicate the surface, on which an image is formed first, is provided, in this image-forming device. SOLUTION: When an image is formed on a first surface (face surface), a sheet is inserted in manual feed guide 57 in such a manner that a cut section 1c may locate at the right lower place. Also, when an image is formed on a second surface (rear surface) after the image has been formed on the first surface, the sheet is inserted in such a manner that the cut section 1c may locate at the right upper place. Then, the cut section 1c, which is mark to indicate the surface wherein the image is formed first, is provided on the sheet 1A, and the insertion direction is indicated by the cut section 1c. Thus, the insertion direction becomes easier to know for a user. This image-forming device is constituted in such a manner that respective four corners may curl downward, i.e., the sheet may curl in a manner to expand upward when the manually fed sheet 1A or a rolled sheet is inserted.

Abstract: PROBLEM TO BE SOLVED: To make shallow the depths of recesses, which are generated in a tungsten plug, and to make the distribution of the depths uniform extending over the whole silicon wafer by a method, wherein the film thickness, which is located on the peripheral edge part of the wafer, of a tungsten film is formed thicker than that, which is located on the central part of the wafer, of the tungsten film. SOLUTION: In a CVD device, a second gas-feeding means 21, which feeds H2 gas along the peripheral edge of a wafer 13 from the direction under the lower part of the wafer 13, is provided. When the mixed gas produced by compounding raw gas WF6 , silane gas, which is a gas for reduction use, and H2 gas which is a carrier gas, is fed to the wafer 13 from above the wafer 13. At the same time, the H2 gas is fed from a direction under the lower part of the wafer 13, a tungsten film 7 is formed on the wafer 13 by a prescribed reaction.  As the feed rate of the H2 gas from the direction under the lower part of the wafer 13 is increased from zero, a film thickness difference between the film thicknesses of the central part and peripheral edge part of the film 7 is decreased and when the feed rate of the H2 gas from the direction under the lower part of the wafer is increased more than that of the H2 gas from over the wafer, the film thickness, which is located on the peripheral edge part of the wafer of the film 7 becomes thicker than that of the central part of the film 7.

Title: Electron-ray exposure device
Inventor: MATSUZAKA TAKASHI
IPC: H01L21/027
Filed: 1983-12-28
Abstract: PURPOSE:To accelerate the response properties of a convergent deflection system and improve the positional accuracy of the system even when the quantity of focal displacement with the deflection of electron beams is increased by reducing the outer diameter of an auxiliary coil compensating focal displacement to not more than half the inner diameter of the magnetic pole of an objective. CONSTITUTION:The coil diameters of auxiliary lenses 2 mounted along the inside of a magnetic path 1 for an objective are reduce to not more than half the inner diameter of the magnetic path. Consequently, since the greater part of magnetic lines of force 6 passing through the outside of an auxiliary lens 5 do not intrude to a magnetic path 4 and passes in a space between the magnetic path 4 and the auxiliary lens 5, the greater part is closed by itself in a magnetic field viewed from the objective side, thus extremely reducing an effect on the periphery. That is, the intensity of the magnetic field intruding to the magnetic path 4 is reduced to one eighth or less of conventional devices when the coil diameter is reduced to not more than half, and the magnitude is approximately the same extent as deflection of 2-2.5mm. square. Accordingly, even when electron beams are deflected extending over a range wider than 3mm. square or more, a convergent deflection system having excellent response properties can be realized without deteriorating the positional accuracy of electron beams.

IPC: G09G5/00
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To reduce the number of line memories required for conversion and to reduce a circuit scale of a video signal conversion device. SOLUTION: A write enable pulse LWE and a write address reset pulse LWRST being timing pulses starting a write means of a line memory 5 are delayed by a delay time d2 by a delay element 24, and phase differences are caused between the LWE and LWRST and a read enable pulse LRE and a read address reset pulse LRRST being the timing pulse starting the read means. The phase differences are the sizes so that a horizontal blanking period of an input video signal 2 contains the horizontal blanking period of an output video signal 25.

Abstract: PROBLEM TO BE SOLVED: To correct the distortion of a radioscopic image and X-ray pickup image and facilitate the application to an existing device at low cost by imparting distortion correcting function to an optical system for optically transmitting the output image of an X-ray image intensifier. SOLUTION: The X-ray transmitted by a subject 10 is incident on an X-ray image intensifier 12, and the output image converted into an optical image of visual light is distributed to a TV camera 14 and a film photographing device 15 by an optical system 13.
