  • Publication number: 20230152038
    Abstract: A heat treatment apparatus includes a heating unit, a chamber, an exhaust unit, a partition unit and a switching unit. The heating unit supports and heats a substrate on which a film of a processing liquid is formed. The chamber surrounds the substrate supported by the heating unit. The exhaust unit is configured to discharge a gas from an inner space of the chamber through a discharge opening located near the heating unit. The partition unit is configured to partition the inner space of the chamber into a first space where the substrate on the heating unit is exposed and a second space located above the first space. The switching unit is configured to switch between a first state where the gas is discharged by the exhaust unit through the first space and a second state where the gas is discharged by the exhaust unit through the second space.

  • Patent number: 8858710
    Abstract: An object is to suppress differences in concentration between processing gases supplied to a plurality of works in a chemical solution vaporizing tank. The chemical solution vaporizing tank includes a tank body having a plurality of vaporizing chambers formed by laterally and airtightly partitioning an internal space of the tank body, a chemical solution passage located under a liquid level in each vaporizing chamber and formed at each partition member for passing the chemical solution between the vaporizing chambers, and a gas passage located above the liquid level in each vaporizing chamber and formed at the partition member to communicate the vaporizing chambers with each other for uniformizing pressures in the respective vaporizing chambers. A quantity of the channel layer in each vaporizing chamber is controlled by managing, e.g., the liquid level.

  • Publication number: 20100211291
    Abstract: An abnormality detection device determines whether an injection correction amount of each cylinder at the time when maximum rotation numbers are equalized is outside a normal range if the equalization of the maximum rotation numbers among cylinders is completed in an idle stable state. The abnormality detection device determines that an abnormality exists on an injector side if the injection correction amount of a specific cylinder is outside the normal range and a rotation number fluctuation difference of the specific cylinder is in a normal range. The abnormality detection device determines that the abnormality exists on an engine side if the injection correction amount of a specific cylinder is outside the normal range and the rotation number fluctuation difference of the specific cylinder is outside the normal range.
