Title: Sealing process
Inventor: GRAHAM CLOUGH
IPC: B65B31/00
Filed: 1982-01-19
Granted: 1988-02-23
Abstract: A container is sealed by applying an intermediate membrane of gas- permeable microporous plastics, extracting headspace gas through the membrane and applying a final barrier membrane.

Title: Washing machine
Inventor: IKEDA YOSHIO
IPC: D06F37/14
Filed: 1984-06-20
Granted: 1989-11-30
Abstract: Clothes are washed in a washing tank (4) with a movable side wall (6) rotatable in 2-directions.  This wall shaped like a circular cage with bottom is located below a fixed side wall (5) of the tank to wash clothes by the effects of the friction at the fixed wall and rotation of the movable wall relative to the fixed wall.  Projections (9,20,21,22) for friction of the clothes are formed on the inner side surface of the movable wall and other taller surface of the movable wall.  The movable side wall operates alone for a small wash load, while with a large load the load provides frictional force between the two wall.

Granted: 1994-10-22
Abstract: The system exhausts reactive toxic gas, manages a high vacuum state to prevent a thin film from being polluted, and performs a real time analysis of the thin film in the process of the CBE/ALE growth. The vacuum system comprises a long manipulator (11) equipped on one side of a load lock/analysis chamber (B) in order to transfer a base plate; gate valves (5,13,7,12) for preventing pollution between the growth chamber and the load lock/analysis chamber (B); a turbo molecular pump (5) connected to the chamber (A); an suction pump (13)/an ion pump (14) connected to the chamber (B); a titanium pump (8).

Title: Method for preventing a passivation of zinc-anode in electroplating a zn-ni alloy
Inventor: KIM TAE-YOP
IPC: C25C7/00
Filed: 1991-10-01
Granted: 1993-07-22
Abstract: A  zinc  anode  passivation,   which   is   generated   from electroplating  a  zinc-nickel  alloy   in   zinc-nickel   plating solution, is prevented by using a zinc-aluminum alloy  instead  of zinc, which is made by adding 1.0-7.0 wt.% aluminum  (Al)  to  the zinc, as an anode, and electroplating in the zinc-nickel  solution added with 5/30 cc/l acetic acid.  This  method  makes  preventing linear defect such as anode streak, lowering electric  power  cost and  improving  producbility  by  enlarging  continuous  operating times.
