Inventor: MATSUMOTO YOSHIMASA
IPC: B32B5/18
Filed: 1993-12-15
Abstract: PURPOSE:To demonstrate superior color contrast and tone effect by destroying sponges of a colored translucent sponding layer by means of welder embossing, changing the color of a layer to the color represented before foaming, enhancing the transparency of the layer and relieving clearly the color of a colored translucent layer. CONSTITUTION:A sheet is formed by laminaing successively a colored opaque layer, a colored translucent sponge layer and a colored transparent surface coated layer. Embossed letters, patterns and the like are demonstrated on the colored opaque layer. The colored translucent sponge layer is foamed by mixing a polyvinyl chloride compound with various kinds of foaming agents, and superior color contrast and tone effect are demonstrated. The color phase effect and the depth of color are demonstrated on the colored transparent surface coated layer. When the sheet is welder embossed, heat is generated to respective layer inside, particularly cells in the colored translucent sponge layer are destroyed to eliminate the irregular reflections, make the layer transparent and changed into the color represented before foaming. The color of the colored opaque layer as a substrate is relieved to demonstrate the desired letters and patterns.

Title: Manufacture of power transmission belt
Inventor: KANAMORI SHOJI
IPC: B29K105/24
Filed: 1991-12-12
Abstract: PURPOSE:To improve the resistance to lateral pressure of a belt, prevent the flexural deformation of the belt in the direction of the lower part of a pulley from occurring and consequently improve its service life by a method wherein short fibers are orientated in the width direction of a forming drum by winding solid sheet round the forming drum to the predetermined thickness. CONSTITUTION:Short fiber containing gum arabic is prepared by mixing short fibers 6 in gum arabic 9, which is made by dissolving rubber in organic solvent so as to be formed in the shape of sheet, in which the short fibers are orientated in a certain direction, and then dried. The obtained solid sheet 16 is wound round a forming drum to the predetermined thickness so as to be able to contain a large amount of the short fibers 6 in a compressive rubber layer 7. Accordingly, the resistance to lateral pressure of a belt is improved remarkably. Further, since the solid sheet 16 is produced out of the gum arabic 9, the surface of the sheet is smooth, though the sheet contains high concentration of short fiber content. Furthermore, since the dimensions of the sheet are exact, the compressive rubber layer 7 can be laminated accurately to one another.

IPC: F16C35/12
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a main shaft unit capable of assuring proper change of pre-load to be applied to a roller bearing. SOLUTION: A movable sleeve 11 is axially slid by hydraulic pressure, so a roller bearing 5b is pressed to apply pre-load to the roller bearing 5b, and the pre-load applied to the roller bearing 5b is changed in accordance with the rotation number of a main shaft 2. A static pressure applying part 22 to apply hydraulic pressure to the movable sleeve 11 is formed, and in changing the pre-load at least, the movable sleeve 11 is slided as the hydraulic pressure is applied to the static pressure applying part 22. Slide resistance of the movable sleeve is thus reduced, and a correct pre-load can be applied to the roller bearing 5b.

Abstract: PROBLEM TO BE SOLVED: To provide a thin-bladed kitchen knife, etc., having superior properties and particularly excellent in property of releasing after cutting, by treating a metal powder composition, having respectively specified composition and grain size, by the prescribed stages. SOLUTION: First, in a compacting stage, a metal powder having the undermentioned composition is held in a state of a thin layer of uniform thickness and compacted into plate-like state having a horizontal outline of an object of production under a pressure of (1.0 to 4.0)ton/cm<2> . The composition ratio of the metal powders is regulated so that it satisfies Ti:Al:V=(About 90):(about 6):(about 4), and further, the average grain size of respective metal powders is regulated to <=35μm. Then, in a sintering stage, the green compact resultant from the compacting stage is sintered at 1200-1300 deg.C.
