Title: Manufacture of electron emitting element
Inventor: TOMII KAORU
IPC: H01J1/30
Filed: 1990-07-05
Abstract: PURPOSE:To easily concentrate the electric field at an edge section when fluctuation occurs in the pattern precision of a negative electrode material layer and a control electrode and improve electron emission efficiency by forming the negative electrode material layer into a pattern with a gradually changed width. CONSTITUTION:A base electrode 2 is formed on an insulating substrate l, and a negative electrode material layer 3 is formed on the electrode 2. The layer 3 is formed into a shape with the width (w) gradually and linearly changed from the tip side to the center side. An insulating layer 4 is formed on the lower outer edge section of the layer 3 on the electrode 2 and the portion where the layer 3 is not formed, and an insulating layer 5 and a control electrode 6 are formed in sequence on the layer 4 at the preset interval from the layer 3. When voltage is applied so that the layer 3 is made negative and the electrode 6 is made positive, lines of electric force are concentrated at the edge section 3a of the layer 3. The widths of the layer 3 and electrode 6 are gradually changed according to location, and the field intensity is changed. A stable electron emission characteristic is obtained even when dispersion occurs on the pattern precision of the layer 3 and electrode 6 when they are manufactured.

Title: Doctor blade
Inventor: SHIGETA TATSUO
IPC: B41F31/20
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To obtain a doctor blade which causes no plate fog even in the case where printing is performed at a practical printing speed and for a practical printing length (number of sheets to be printed) in gravure printing which uses water-base ink, while providing long service life for the doctor blade for scraping excess ink with its forward end pushed against a gravure printing roller. SOLUTION: This doctor blade is composed of a core metal 3a made of carbon steel or stainless steel, a primer coating 3b harder than the hardness of the core metal 3a, which is coated on one face or both faces of the core metal 3a, and a diamond-like carbon coating 3c further overcoated thereon. The diamond-like carbon coating has high smoothness and high hardness and is extremely small in its Young's modulus. The coating has flexibility and makes the doctor blade easily slidable on the surface of printing plate, whereby the doctor blade is made accessible to water-base ink existing in sandpaper marks formed in a non-image area on the surface of the printing plate and ink which passes through the underside of the doctor blade is controlled to an extremely small quantity.  Accordingly, the doctor blade has excellent wear resistance and can favorably maitain the shapes of ink for a long time. Thus, plate fog can effectively be avoided, and no plate fog is caused even in the case where printing is performed at a practical printing speed and for a practical printing length.

Abstract: PURPOSE:To remove a fear of slipping off from a cartridge by making the cartridge a compact form during conveyance of a package and storing and by controlling naturally motion of image receiving paper by a method wherein the cartridge is enabled to be transformed to first and second two modes according as it is in use or in non-use. CONSTITUTION:Positioning of a first and a second housings 1, 2 is performed by engaging holes 1a, 1b for positioning with pins 23a, 23b in charging a cartridge, the cartridge 3 presents naturally a second mode, and said state is kept atable. When the cartridge 3 presents a first mode, the first housting 1 and the second housting 2 come to be of a state wherein mutual projected images are so folded as to be superimposed with each other. Since side wall surfaces are parallel, they can be effectively housed in a rectangular parallelepiped case. Since a presser component 8, when the first mode is presented, presses form above so as to control vertical motion of image receiving paper 10, the image receiving paper 10 never drops off from the cartridge while carrying it.
