Title: Production of aluminum alloy sheet for can cover having superior paint film adhesion
Inventor: TANAKA NOBORU
IPC: C23C22/38
Filed: 1988-03-09
Abstract: PURPOSE:To produce an Al alloy sheet for a can cover having superior adhesion of a paint film by forming a phosphate-chromate film on the surface of an Al alloy sheet as stock to be formed into a can cover after coating with a treating soln. having a specified compsn., heating the sheet at a low temp. and carrying out coating with paint. CONSTITUTION:When a phosphate-chromate film is formed on an Al alloy sheet as stock for a can cover and coated with paint, the sheet is degreased, etched and treated with a phosphating-chromating soln. contg. chromic acid and hydrofluoric acid in 0.28-0.7 ratio of hydrofluoric acid to chromic acid and further contg. phosphoric acid to form a phosphate-chromate film having many etching pits. The sheet is then heated to a relatively low temp. of 20-50 deg.C so as to nearly prevent dew condensation on the surface of the sheet. After the lapse of 30-60min, coating with paint is carried out. An Al alloy sheet for a can cover having high adhesion of a paint film is produced.

Title: Alumina-carbon castable
Inventor: SOEDA TOMOMI
IPC: C04B35/66
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To decrease a fusing damage of a molten steel and to improve durability by using an alumina-carbonaceous aggregate containing carbon. SOLUTION: The alumina-carbonaceous aggregate is produced, for example, by mixing alumina of <=3 mm particle size, carbon of <=1 mm particle size and a resin as a binder, and granulating in a granulating machine into granules of about 8 mm diameter. As for the carbon, pitch, coke, carbon black and graphite can be used. As for the alumina, sintered alumina, electrofused alumina and natural alumina can be used. When the particle size of the alumina is >=3 mm, the carbon can not be uniformly dispersed or mixed. By adjusting the particle size of the carbon to <=1 mm, good dispersion is botd. By using the alumina-carbonaceous aggregate above described, the production of an alumina-carbon castable, especially having >=10 wt.% carbon content is made easy.

IPC: F27D17/00
Filed: 1984-03-26
Abstract: PURPOSE:To contrive to efficiently recover potential heat from sintered ore, by partitioning a course to transfer highly heated granular and lumpy matter by partition panels which cross the course to the transfer direction, and by alternately providing sensible heat recovering zones and sensible heat non-recovering zones in a waste heat recovering equipment of a sintering furnace. CONSTITUTION:Sintered ore 2 transferred to the feed opening 1 of a cooling equipment through a chute is cooled by an upward induced draft while it is moving on the pallet of a cooling equipment and is discharged. A number of partition panels 8 are provided to the inside of a hood covering the pallet of a cooling equipment. Suction ducts 5a to gather exhaust gas are connected to the alternate zones partitioned by the panels in order to recover sensible heat from the gas.

Title: Apparatus used for pretreatment of wood
Inventor: YASUJIMA MINORU
IPC: B27K1/02
Filed: 1992-02-05
Abstract: PURPOSE:To enable wood to be treated with a drug or with resin impregnation immediately after treating the wood for liquid permeability at a low cost by a method wherein an introduction opening which sends high pressure gas into an autoclave and a blasting valve which releases the high pressure gas are provided, and an exhaust silencer is provided after the blasting valve. CONSTITUTION:At first, an wood block 8 is put on a carriage 7, which is housed in an autoclave 1. Then, pressure in the autoclave is kept at 2-20kg/cm<2> by injecting high pressure gas fed via an air pressure valve 4 from a compressor 5 therein. Thereafter, the pressure in the autoclave is reduced to atmospheric pressure by releasing suddenly the blasting valve 2. Thus, the high pressure gas injected in the wood is expanded suddenly in volume. After keeping releasing time for several seconds several minutes, injection of the high pressure gas is carried out again. This cycle is repeated several times - several hundreds times. Then, a wall film of the wood is partially destroyed by quick expansion in volume per each cycle, and its permeability is improved. Since blasting exhaust is accompanied by a high-pitched tone and fluctuation in atmospheric pressure at that time, the blasting exhaust is carried out through an exhaust silencer 3 from a standpoint of pollution prevention.
