Title: Register capable of obtaining multicolor receipt
Inventor: KIMURA TAKEMORI
IPC: B41J29/40
Filed: 1984-05-18
Abstract: PURPOSE:To make it possible to enhance the image of a receipt, by sectionalizing a receipt printing seal surface stamp into various color sections such as red, blue and yellow and making it possible to obtain a multicolor receipt simultaneously even on the same stamp surface. CONSTITUTION:A seal surface is molded from a soft open cell porous body comprising a synthetic resin and impregnated with ink to form a continuously usable stamp. Seal surfaces 1-3 demarcated by demarcation lines 4 are respectively impregnated with inks having different colors. The demarcation lines 4 are formed by injecting an adhesive in gaps formed by cutting the seal surface or inserting ink impervious films in said gaps or bringing pore parts of an open cell porous body to a closed cell one by applying heat to the seal surface itself according to demarcation lines so as to form the seal surface on a fixed table 5 into seal surface sections 1-3 having proper shapes. Furthermore, similar treatment is applied to the bottom surface, the lateral surface and the surface other than the stamping surface of the seal surface to prevent the color mixing, drying and oxidation of ink.

Title: Production of hydrogenated polymer
Inventor: MORITA HIDEO
IPC: C08F8/04
Filed: 1981-07-01
Abstract: PURPOSE:To obtain a hydrogenated polymer excellent in weather resistance, heat resistance, etc., under mild hydrogenation conditions within a short time, by hydrogenating a diene polymer with the aid of a hydrogenation catalyst comprising a solution of a noble metal colloid in a prim. or sec. alcohol. CONSTITUTION:A noble metal compound such as palladium chloride or chloroplatinic acid is dissolved in a prim. or sec. alcohol (e.g., ethanol or n-butanol). Then, a blackish brown, uniform noble metal colloid is formed by adding a polar group-containing synthetic high-molecular compound serving as a protective colloid, e.g., polyvinylpyrrolidone or poly(methyl vinyl ether), to the above solution and heating the solution to reduce the noble metal compound to the metal. The purpose hydrogenated polymer is prepared by hydrogenating a diene polymer (e.g., polybutadiene) in a solvent such as tetrahydrofuran or toluene in the presence of a hydrogenation catalyst comprising an alcohol solution of the above-produced noble metal colloid.

Abstract: PURPOSE:To produce the blurring on the image formation surface with a simple mechanism by deviating a focus and to remove moire by providing the reader with a means for changing focal distance of reflected light form a print matter. CONSTITUTION:When operation panel 1 inputs information that the original 1 is an offset printed matter, the CPU actuates the solenoid driving section to make the solenoid 13 insert a glass plate 12 having a predetermined thickness in the light path. Thus, the high frequency range component of a photo-image is removed, and as a result the same effect is obtained that a lens array 5 is moved, thereby generating a shade on the image-formation surface of image sensor 6. For gravure print such as photograph, insertion of a glass plate is stopped and the object is treated for photoelectric conversion at the best focus. Or, by rotating a pivotal section 24 via a driving motor gear and incling the glass plate 12 to the light axis in conformity with the magnification of zoom lens 20, thickness of the glass plate is substantially varied to make a shade at the focus. Furthermore, in the case or gravure print, the glass plate 12 is inclined in nearly parallel with the light axis to remove moire.

Prepressure is given to balls 8 interposed between the ball screw shaft 7 and ball nut 9 to prevent also the axial play of the ball screw shaft 7 for precise location. When a moment load acts on the ball screw shaft 7, moment is shared by the ball nut 9 and spline nut 15 to provide high support rigidity.
