    Abstract: The present invention is related to a method and apparatus for liquid treating and drying a substrate, such as a semiconductor wafer, the method comprising the step of immersing a substrate or a batch of substrates in a tank filled with a liquid, and removing the substrate(s) through an opening so that a flow of the liquid takes place through the opening during removal of the substrate. Simultaneously with the removal, a reduction of the surface tension of the liquid is caused to take place near the intersection line between the liquid and the substrate. For acquiring such a tensio-active effect, a uniform flow of a gas or vapor is used, or/and a local application of heat. The invention is equally related to an apparatus for performing the method of the invention.

    Abstract: Chambers each include an inlet port for supplying N2 gas and an outlet port for discharging an inner atmosphere, and therefore the chambers have different amounts of supply of N2 gas in a unit of time and different amounts of discharge of inner atmosphere in a unit of time. With this structure, the first to fourth processing chambers are controlled to have the lowest inner pressure(p3), a transfer module is controlled to have an inner pressure (p2) higher than the inner pressure (p3) and a loader and an unloader are controlled to have the highest inner pressure (p1). That eliminates the necessity for keeping the whole substrate processing apparatus at the highest inner pressure (p1) and supplying a large amount of N2 gas, and therefore it is possible to achieve processings of substrate at lower cost, with shorter purge time and less contamination of substrate.

Also in the film path is a region of high humidity followed by two buffing rollers for polishing the film to be cleaned. Two of the rollers are connected to a vibration generator mechanism. Vibration of the rollers is caused by a rotating disk having two embedded magnetic elements which pass closely adjacent to magnetic elements at the end of rollers' shafts. As the rotating magnets pass by the two shafts, a repulsion force causes the shafts to move away. Connected to each of the shafts is an O-ring which acts as a compression spring that biases its respective shaft back to its starting position after the magnetic elements have moved away from each other. By rotating the disk with the magnetic elements at 3600 rpm a vibration is set up in the shafts at a rate of 7200 times per minute.

    Abstract: A garbage truck for handling large trash bins has a system incorporated therein for cleaning and deodorizing the bins after they have been emptied. Immediately after a bin has been emptied into the garbage truck trash compactor and while it is in an inverted position, the bin is sprayed with hot water ejected from nozzles mounted on the truck to the rear of the compactor. This spraying operation is controlled from the cab of the truck and is continued long enough with a large enough volume of water to insure thorough cleaning of the bin. After the bin has been washed it is returned to its original position on the ground and sprayed with deodorant from jet nozzles mounted on the top of the truck cab, this operation also being controlled by an operator in the cab.

  • Patent number: 4381285
    Abstract: The present invention comprises a contact lens sterilizing device (10,54,118) which chemically disinfects contact lenses (L) in a cell (20,64,134) containing antimicrobial solution (42,104,144) and which subsequently transfers the lenses (L) to a storage cell (22,66,136) containing storage solution (44,106,146). Momentum generated as the striker arm (6) of a mechanical timer (2) snaps from a first position to a second position is utilized to propel a cage (C,70,140) holding the contact lenses (L) from the sterilizing cell (20,64,134) to the storage cell (22,66,136), thereby effecting the transfer operation. In one embodiment (10) of the present invention, the striker arm momentum is indirectly imparted to the contact lens cage (C) via a flipper (28). In other embodiments (54,118) of the present invention, the striker arm momentum is directly imparted to the contact lens cage (70,140) via a hook (72,142) integrally formed on the cage (70,140).
