    Abstract: The back surface of a substrate having a front surface coated with a resist film is irradiated with flashes of light emitted from flash lamps. Heat conduction from the back surface of the substrate abruptly raised in temperature by the irradiation with flashes of light toward the front surface thereof occurs to heat the resist film formed on the front surface of the substrate, so that a post-applied bake process is performed. After the completion of the post-applied bake process, a cooling plate cools down the substrate. Regardless of the type of resist film formed on the front surface of the substrate, the substrate has a constant absorptance of flashes of light to allow the resist film to be heated to a constant treatment temperature, because the back surface of the substrate is irradiated with flashes of light.

An annular cooling member is installed at the space for cooling. An actuating mechanism moves the cooling member between a contacting position where the cooling member makes contact with at least one of the inner wall and the outer wall and a non-contacting position where the cooling member does not make contact with any one of the inner wall and the outer wall. A control unit controls at least the actuating mechanism.

  • Publication number: 20110014581
    Abstract: Kilns for processing ceramics and methods for using such kilns are disclosed herein. In one embodiment, a kiln includes an inner body configured to hold one or more ceramic workpieces for processing. The kiln can also include an outer body at least partially surrounding the inner body and spaced apart from the inner body to define an airflow passageway therebetween. The airflow passageway includes an inlet proximate to an upper portion of the outer body and an outlet proximate to a lower portion of the outer body. The kiln can further include an air mover positioned to move air through the airflow passageway from the inlet toward the outlet. In several embodiments, the kiln can additionally include a lid assembly pivotably coupled to the outer body and configured to sealably close against at least the inner body.

  • Publication number: 20100301033
    Abstract: Tunnel kilns serve for the thermal treatment of products in a continuous operation within a production process. The tunnel kilns are usually made up of a number of identical kiln segments, each segment having a blower, heating elements for heating up the fresh air and a common exhaust air line. For the treatment of the products, they are made to pass by either on the suction side or the pressure side of the blower. To reduce the overall volume of such kilns and to save energy, it is proposed to arrange the blower inside the kiln in such a way that it produces a circulatory flow transversely to the direction of continuous transport and to transport the products to be dried through the circulatory flow parallel to one another in the direction of continuous transport both on the pressure side and on the suction side of the blower.

  • Publication number: 20100230396
    Abstract: Embodiments of the present invention relate generally to steam ovens, and particularly to steam ovens configured to generate and deliver steam directly to the oven using a water reservoir in close proximity to an existing oven heat generating system. The steam ovens described may be designed so that they inject steam directly into the oven cavity, and in some instances, generate the steam directly in the oven cavity as well. Certain embodiments are designed with a water reservoir in close proximity to an oven heat generating system such that water in the reservoir is heated, turned to steam, and delivered to the oven cavity via a steam delivery system.

  • Publication number: 20100200563
    Abstract: The invention provides a drawer type cooking device having a cooling fan 56a disposed laterally, so that a space 70 is formed below the cooling fan 56a, enabling a high pressure transformer 55 to be disposed efficiently using this space 70. By the combination of the arrangement, position and orientation of the cooling fan, it becomes possible to reduce the set depth size at the farthest portion of the cooking device body 1. By reducing the depth size, the front surface of a cabinet and the front surface of a door 2 can be disposed flush with each other, without having to sacrifice the depth of the heating chamber 6.

  • Patent number: 7732738
    Abstract: A banquet cart includes a heater received in an opening in the bottom panel of the banquet cart. Plates of food are loaded into the interior compartment of the banquet cart in the kitchen. The heater includes a central heater unit and two heat retention material heating panels. The central heater unit heats the interior compartment of the banquet cart for twenty minutes. The central heater unit is turned off, and smaller heaters are turned on to heat the heat retention material heating panels for forty minutes. The smaller heaters are turned off and the banquet cart is rolled from the kitchen to a hallway proximate to the dining area for serving the plates of food to guests. The heated heat retention material heating panels can maintain the temperature of the air in the interior compartment of the banquet cart warm for approximately two hours and forty minutes, keeping the food in the banquet cart warm.
