  • Patent number: 6865821
    Abstract: A lumber drying kiln employs outside air pressure uses a flexible collapsing bag or cover alone or in combination with walls. The collapsing bag seals against a base to maintain the vacuum. The air pressure against the flexible top keeps the lumber layers from warping or cupping during drying. The lumber stack has alternating layers of hot plates or stickers separating layers of lumber. A bag having an open bottom and made of nylon-reinforced rubber or other strong flexible material is placed over the wood and sealed to the stainless steel platform. A vacuum pump is connected with the bag by means of a manifold and operated to remove air from the enclosed lumber stack, the vacuum strengthening the seal between the base and the bottom of the bag. This chamber design is easily scaled up or down to provide a desired drying capacity.

  • Patent number: 6745494
    Abstract: A system for high-pressure drying of semiconductor wafers includes the insertion of a wafer into an open vessel, the immersion of the wafer in a liquid, pressure-sealing of the vessel, pressurization of the vessel with an inert gas, and then the controlled draining of the liquid using a moveable drain that extracts water from a depth maintained just below the gas-liquid interface. Thereafter, the pressure may be reduced in the vessel and the dry and clean wafer may be removed. The high pressure suppresses the boiling point of liquids, thus allowing higher temperatures to be used to optimize reactivity. Megasonic waves are used with pressurized fluid to enhance cleaning performance. Supercritical substances are provided in a sealed vessel containing a wafer to promote cleaning and other treatment.

  • Patent number: 6742276
    Abstract: A plastic suit drying system comprises a drying chamber with an air warmer, and a mobile dryer rack. The mobile rack has a wheeled air plenum base, a number of drying positions (each comprising three perforated air pipes protruding up from the base), and a flanged air inlet in the back of the base that mates with a connection flange in the drying chamber. Through this flanged connection hot air is forced into the base/plenum and then into the perforated pipes. For use, wet plastic suits are placed upside down on the drying positions. Then, the mobile rack is rolled into the drying chamber so that the rack's flange mates with the drying cabinet's connection flange. Next, the drying chamber doors are closed, and the drying cycle started, during which heated air is blown into the mobile rack plenum and up into the air pipes extending into the suits.

  • Patent number: 6732447
    Abstract: A shoe drying device having two arms and an airflow channel extending therethrough. A spring exerts an outward force on the arms. Each arm includes a member for holding a shoe at an end thereof. During a drying cycle, convection air enters through an air inlet towards the center of the device, flows through the airflow channel, and exits through air outlets in the members for holding a shoe at the ends of the arms. This facilitates more even drying of shoes held in the members for holding shoes.

  • Patent number: 6688020
    Abstract: A substrate processing apparatus and method which can prevent accidents in advance so as to ensure safety against interruption of operations of the apparatus and leakage of processing substances. In a substrate processing method in which wafers W are processed are processed by feeding an ozone gas 5 to the wafers W loaded in a processing vessel 2 while an interior atmosphere in the processing vessel is being exhausted to be passed through an ozone killer 10, the ozone gas 5 is fed under the conditions that the processing vessel 2 is tightly closed, and the ozone killer in its normal state. When the processing is interrupted, an interior atmosphere in the processing vessel 2 is forcedly exhausted. When the gas leaks, the interior atmosphere and a peripheral atmosphere of the processing vessel 2 are forcedly exhausted while the feed of the ozone gas 5 is paused.

  • Patent number: RE38412
    Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.
