Title: Vacuuming of carrier box and carrier box
Inventor: ONO KOJI
IPC: B65D81/20
Filed: 1991-03-26
Abstract: PURPOSE:To enable a rapid vaccuming without dampling objects such as wafers by a method wherein when vaccuming is carried out removing dirty grains inside, flow velocity of gas to be exhausted is reduced during it flows in the vicinity of the objects. CONSTITUTION:When wafers 21 are carried in, a lid 4 is brought into contact with a flange 2 through a seal 3, and sealed sritight with clamps 5. Then a vacuum source is connected to a suction port 7 for vaccuming. In this instance, as a deflector 30 is provided between the suction port 7 and the wafers 21, the gas inside a carry box BX flows first, as indicated by arrows, mainly through gaps between four sides of the deflector 30 and four side walls 10 and 11 of the carrier box BX, and then is exhausted out of the suction port 7. Accordingly, the velocity of an airstream drops down when it flows around the wafers 21. Thus, though a large amount of air exhausted for a short time, there is no possibility that the wafers 21 vibrate or they are damaged because of the vibration.

Abstract: PURPOSE:To raise engine output by adopting an exhaust pipe of large diameter while suppressing increase in size of a pump chamber. CONSTITUTION:Branch pipes 15a, 15b as two paths of a downstream exhaust pipe 15 open into a pump chamber 8. The respective branch pipes 15a, 15b are mutually connected in their juxtaposition on a right-hand side wall of the pump chamber back and forth. If, now sum total of path sectional areas of the branch pipes 15a, 15b is set to be roughly equal to path sectional area of the single pipe portion upstream, vertical width of the exhaust outlet holes in the pump chamber wall becomes smaller than vertical dimension of the single pipe portion. Accordingly, even when in diameter, there is no need for increasing size of the pump chamber 8.
