PROBLEM TO BE SOLVED: To provide a method capable of stably manufacturing a sufficient amount of hydrogen peroxide with a high manufacturing efficiency. SOLUTION: In the direct synthetic method of hydrogen peroxide, a catalytic solution is manufactured by adding a second noble metal salt to a solvent in which first noble metal colloidal particles are dispersed then reducing the solution, and hydrogen and oxygen are passed through the catalytic solution to be reacted to directly synthesize hydrogen peroxide. Here, it is preferable that the first noble metal is palladium, the second noble metal is platinum and the salt of the second noble metal is a hydrochloride or chloride. Also, it is preferable that the existing ratio of the first noble metal to the second noble metal in the catalytic solution is 3:1-9:1 in weight ratio. COPYRIGHT: (C)2007,JPO&INPIT ...

Auto document feeding device, image scanning device and document feeding method

The invention discloses an auto document feeding device and a document feeding method, wherein the lengths of an OUT path and an IN path are made longer than the length of a document of a main size in a traveling direction. The document of the main size stands by for conveyance in a direction of a READ document glass in a state where the entire document is contained in the OUT path or the IN path. The entrance speed of the document into the OUT path or the IN path is equal to the read speed of a scanner. The leading edge of a subsequent document is overlapped on the trailing edge of a preceding document, and the document is conveyed to the READ document glass.

CYLINDER TYPE LIQUID SEALED VIBRATION DAMPING APPARATUS

PROBLEM TO BE SOLVED: To provide a cylinder type liquid sealed vibration damping apparatus which is excellent in the durability and has a long life. SOLUTION: A first rubber-like elastic member 3 is arranged between a first inner cylinder 1 and an intermediate cylinder 2. A second rubber-like elastic member 5 is arranged between the intermediate cylinder 2 and an outer cylinder 4. A pair of liquid chambers 6, the wall of which is the second rubber-like elastic member 5, is formed between the intermediate cylinder 2 and the outer cylinder 4 so as to be positioned on the opposite sides of the intermediate cylinder 2. Further, orifices 7 are formed so as to connect a pair of the liquid chambers 6 with each other. The first inner cylinder 1 is made of steel, and the diameter of the first inner cylinder 1 has been expanded by press-fitting a second inner cylinder 8 into the first inner cylinder 1.
