Exhaust Controlled By Solvent Concentration Patents (Class 34/567)
  • Patent number: 9322594
    Abstract: A drier comprising a drier chamber inside a drier housing. An inner atmosphere of the drier chamber has an elevated temperature relative to the outer atmosphere. An inlet lock and an outlet lock reduce the inflow of the outer atmosphere into the drier chamber and the outflow of the inner atmosphere into the outer atmosphere. The inlet lock comprises a first air curtain, which extends over the inlet lock and which runs upward, and a second air curtain, which is behind the first air curtain in the direction of motion of the objects and which extends over the inlet lock and which runs downward. The outlet lock is designed substantially identically to the inlet lock, however the objects first pass through an air curtain directed downward and then pass through an air curtain directed upward. The conveyor system is designed that the objects are moved continuously and at a substantially constant height through the entire drier housing.

  • Patent number: 8959792
    Abstract: Systems and methods are provided for controlling a dryer of a printing system. The system comprises a controller and a sensor. The controller is operable to determine a speed of a web of print media traveling through a dryer, and to apply power to a heating element of the dryer based on a power profile that models a non-linear relationship between power applied to the heating element and speed of the web. The controller is further able to determine a type of media for the web, and to select the power profile based on the type of media.

  • Patent number: 7954255
    Abstract: A drying apparatus with a vaporized-solvent-recovery function including: a concentration-at-the-end-of-drying data memorizing device to memorize a concentration of a vaporized solvent at the end of a drying operation of an object to be dried in a processing path; a vaporized solvent; an end-of-drying judging device to judge an end of drying of the object by comparing the concentration measured by the vaporized-solvent-concentration measuring device with the concentration memorized by the concentration-at-the-end-of-drying data memorizing device; and a drying-operation controlling device to control the drying operation of the object in a processing bath and to end the drying operation in response to a judgement by the end-of-drying judging device that the concentration measured by the vaporized-solvent-concentration measuring device is equal to the concentration memorized in then concentration-at-the-end-of-drying data memorizing device.

  • 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.
